Letter of Intent Template for Acquiring an Email Marketing Agency

A plain-language LOI framework and negotiation guide purpose-built for retainer-based email marketing agency acquisitions in the $1M–$5M revenue range — covering purchase price, earnouts tied to client retention, exclusivity, and due diligence scope.

A Letter of Intent (LOI) is the pivotal document that moves an email marketing agency acquisition from informal conversations to a structured, time-bound process. For agency deals in the $1M–$5M revenue range, the LOI must address the unique risks of this business model: month-to-month client contracts, founder dependency on key relationships, platform licensing tied to Klaviyo or HubSpot accounts, and the challenge of separating recurring retainer revenue from one-time project income. Unlike asset-heavy businesses, an email marketing agency's value lives in client relationships, institutional knowledge, and repeatable delivery systems — none of which show up on a balance sheet. A well-drafted LOI signals to the seller that you understand the business, protects you during due diligence with an exclusivity period, and establishes the economic framework — purchase price, deal structure, earnout mechanics — before either party invests in legal and accounting fees. This guide walks you through every section of a standard LOI for this industry, explains what to negotiate, and highlights the mistakes that derail deals before closing.

LOI Sections for Email Marketing Agency Acquisitions

1. Parties and Transaction Overview

Identifies the buyer entity (or entity to be formed), the seller, and the business being acquired. Specifies whether the transaction is structured as an asset purchase or stock/membership interest purchase — a critical distinction for email marketing agencies where client contracts, Klaviyo/HubSpot platform accounts, and employee agreements may need to be individually assigned in an asset deal.

Example Language

This Letter of Intent is entered into as of [Date] between [Buyer Name or Acquiring Entity] ('Buyer') and [Seller Legal Name] ('Seller'), the owner of [Agency Name], a [State] [LLC/S-Corp] ('the Company'). Buyer proposes to acquire substantially all of the assets of the Company, including client contracts, email platform accounts and agency partnerships, proprietary templates and automation frameworks, domain and brand assets, and associated goodwill, pursuant to a definitive Asset Purchase Agreement to be negotiated in good faith by both parties.

💡 Sellers often prefer a stock sale for tax efficiency (capital gains treatment on the full amount), while buyers — especially SBA borrowers — typically prefer an asset purchase to avoid inheriting unknown liabilities and to achieve a stepped-up tax basis. For a Klaviyo Elite Partner agency, confirm early whether the platform partner status transfers under an asset deal or requires a new application, as this can affect deal structure preference.

2. Purchase Price and Valuation Basis

States the proposed total enterprise value and the EBITDA or SDE basis on which it is calculated. For email marketing agencies, the LOI should explicitly reference the trailing twelve-month (TTM) adjusted EBITDA, the multiple applied, and the revenue quality assumptions underpinning the valuation — particularly the percentage of revenue classified as recurring retainer versus one-time project work.

Example Language

Buyer proposes a total purchase price of $[X,XXX,000], representing approximately [3.5x–4.5x] of the Company's trailing twelve-month adjusted EBITDA of $[XXX,000], as preliminarily calculated based on financial statements and representations provided by Seller. This valuation assumes that no less than 70% of trailing revenue is attributable to recurring monthly retainer agreements and that no single client accounts for more than 25% of total revenue. Material deviation from either assumption discovered during due diligence will be grounds for purchase price renegotiation.

💡 Email marketing agencies frequently present EBITDA add-backs that include founder compensation above market rate, personal vehicle expenses, and non-recurring software investments. Scrutinize each add-back. If the agency derives meaningful revenue from performance-based or one-time campaign launches, insist on a separate revenue quality schedule before finalizing the multiple. Sellers will push for the high end of the 3x–5.5x range by citing net revenue retention above 110% — require documentation before accepting that claim.

3. Deal Structure and Payment Terms

Outlines how the purchase price will be paid, including the cash at close, SBA loan proceeds, seller note, and any earnout component. For email marketing agency acquisitions, earnouts tied to client retention over 12–24 months post-close are standard because the primary risk is client attrition following a change in ownership.

Example Language

The purchase price shall be funded as follows: (a) $[XXX,000] in cash at closing, sourced from an SBA 7(a) loan representing approximately 80–85% of the purchase price; (b) a Seller Note of $[XX,000] subordinated to the SBA lender, bearing interest at [6–7%] per annum, payable over [24–36] months; and (c) an earnout of up to $[XX,000] payable over 24 months post-closing, contingent on the Company retaining no less than [85%] of trailing twelve-month retainer revenue as measured on the 12-month and 24-month anniversaries of the closing date, with retainer revenue calculated on a dollar-weighted basis using contract values as of the closing date.

💡 Sellers will resist earnouts tied to revenue thresholds they feel are outside their control post-close. Negotiate a shared-risk framing: the earnout protects the buyer if clients leave due to transition disruption, but the seller should have no earnout exposure for client losses attributable to the buyer's operational decisions. If the seller will be actively involved post-close as a consultant, tie part of the earnout to their specific client retention performance rather than aggregate agency revenue. SBA lenders will require the seller note to be on full standby for 24 months — factor this into seller cash flow expectations.

4. Due Diligence Scope and Timeline

Defines the categories of information the buyer requires access to, the timeline for completing due diligence, and each party's obligations during the process. For email marketing agencies, due diligence must go beyond financials to include client contract review, platform account access verification, team retention risk assessment, and deliverability/performance metric analysis.

Example Language

Buyer shall have [45–60] calendar days from the date of full execution of this LOI to complete due diligence ('Due Diligence Period'). Seller agrees to provide timely access to the following: (i) three years of financial statements and tax returns with an itemized EBITDA add-back schedule; (ii) all client contracts, statements of work, pricing schedules, and renewal or cancellation history for the trailing 24 months; (iii) login access or screen-share review of the Company's email service provider accounts (Klaviyo, HubSpam, HubSpot, or equivalent), including account-level revenue, deliverability metrics, and subscriber list ownership documentation; (iv) organizational chart, employee compensation schedules, and any existing non-solicitation or non-compete agreements; (v) documentation of all active software subscriptions, vendor contracts, and agency partner agreements including transferability terms; and (vi) a client concentration analysis showing each client's contribution to trailing revenue and the nature of their contractual relationship with the Company.

💡 Forty-five days is the minimum reasonable timeline for an agency acquisition of this complexity; push for 60 days if the deal involves an SBA loan, as lender processing adds time. Require the seller to provide a data room within 10 business days of LOI execution — delays at this stage often signal disorganized financials or undisclosed client issues. If Klaviyo or HubSpot agency partner status is material to the deal thesis, confirm transferability directly with the platform before the LOI is signed, not during due diligence.

5. Exclusivity Period

Grants the buyer an exclusive negotiating window during which the seller agrees not to solicit, negotiate, or accept offers from other potential buyers. This protects the buyer's investment of time, legal fees, and due diligence costs.

Example Language

In consideration of Buyer's commitment to proceed in good faith and incur due diligence and legal costs, Seller agrees to grant Buyer an exclusive negotiating period of [60] calendar days from the date of full execution of this LOI ('Exclusivity Period'). During the Exclusivity Period, Seller shall not, directly or indirectly, solicit, encourage, initiate, or participate in discussions or negotiations with any third party regarding the sale, merger, recapitalization, or other disposition of the Company or its assets. Buyer may request a [15]-day extension of the Exclusivity Period in writing if due diligence remains materially incomplete due to delays outside Buyer's control, which Seller shall not unreasonably withhold.

💡 Sellers represented by M&A brokers may push back on exclusivity periods longer than 45 days, particularly if they are fielding competing interest. Sixty days is reasonable and defensible for an SBA-financed deal. If the seller insists on a shorter window, negotiate a built-in extension mechanism as described above. Confirm that the exclusivity clause covers the seller's business broker or advisor — some deals have fallen apart because the broker continued shopping the deal while the buyer was in due diligence.

6. Transition, Non-Compete, and Consulting Agreement

Outlines the seller's post-closing obligations, including a transition consulting period to introduce the buyer to clients and transfer institutional knowledge, as well as non-compete and non-solicitation covenants that protect the buyer's investment in the client relationships and team.

Example Language

Seller agrees to provide transition consulting services for a period of [90] days post-closing at no additional cost to Buyer, including personal introductions to all active retainer clients, knowledge transfer sessions covering campaign strategy, client communication cadences, and platform-specific workflows, and reasonable availability to support account manager onboarding. Following the transition period, Seller agrees to enter into a Non-Compete Agreement restricting Seller from directly or indirectly operating, consulting for, or holding an ownership interest in any business providing email marketing strategy or campaign management services within the [United States / relevant geographic market] for a period of [3] years from the closing date, and a Non-Solicitation Agreement restricting Seller from soliciting the Company's clients or employees for [3] years post-closing.

💡 For email marketing agencies where the founder owns key client relationships, the transition consulting period is arguably the most deal-critical clause in the entire LOI. Ninety days is the floor; if the founder is the primary strategist on accounts representing more than 50% of revenue, negotiate for 6 months with a tiered wind-down. Non-competes in the 3-year, national-scope range are standard and generally enforceable in asset deals — sellers may push back on national scope, but given the remote-first nature of email marketing, geography restrictions are largely meaningless without national coverage.

7. Confidentiality and Employee/Client Communication

Establishes mutual obligations to keep the transaction confidential until closing, protecting the seller from premature disclosure to clients or employees and protecting the buyer's competitive position and negotiating leverage.

Example Language

Both parties agree to maintain strict confidentiality regarding the existence and terms of this LOI and the proposed transaction. Seller shall not disclose the proposed transaction to any client, employee, vendor, or platform partner without Buyer's prior written consent. Buyer shall not contact any of the Company's clients, employees, or vendors without Seller's prior written consent, except as jointly agreed upon as part of the due diligence process. Any breach of this confidentiality provision shall entitle the non-breaching party to seek injunctive relief in addition to any available damages. Both parties acknowledge that premature disclosure could cause irreparable harm to the Company's client relationships and enterprise value.

💡 Email marketing agencies are particularly vulnerable to confidentiality breaches because their client and employee communities are small and interconnected — a whisper in a Klaviyo Slack community or a LinkedIn message can trigger client inquiries or employee anxiety within days. Establish a clear, joint communication plan before any information is shared beyond the core deal team. The buyer's due diligence calls with the seller's team should be framed as 'operational review' conversations until a definitive agreement is signed.

8. Conditions to Closing

Lists the material conditions that must be satisfied before the transaction can close, including financing approval, satisfactory completion of due diligence, execution of definitive agreements, and any third-party consents required for contract assignments.

Example Language

The consummation of the proposed transaction is conditioned upon, among other things: (i) Buyer obtaining SBA 7(a) financing on terms acceptable to Buyer in its reasonable discretion; (ii) Buyer's completion of due diligence to Buyer's reasonable satisfaction, with no material adverse findings; (iii) execution of a mutually acceptable definitive Asset Purchase Agreement and all ancillary documents; (iv) receipt of any required third-party consents, including assignment of material client contracts and transfer or reissuance of email service provider agency partner accounts (including Klaviyo Partner Program or HubSpot Solutions Partner status, as applicable); (v) key employees identified during due diligence executing employment or contractor agreements acceptable to Buyer on or before closing; and (vi) no material adverse change in the Company's revenue, client base, or operating condition occurring between the date of this LOI and closing.

💡 The SBA financing condition is non-negotiable for most lower middle market buyers and should be stated plainly. Sellers should be aware that SBA approval typically adds 60–90 days to the timeline post-LOI. For agencies with a Klaviyo Elite or Premier Partner designation, treat the platform partner transfer as a hard condition to closing — losing that status post-close could eliminate a meaningful lead generation and co-marketing channel that the buyer may have paid a premium to acquire.

9. Binding vs. Non-Binding Provisions

Clarifies which LOI provisions are legally binding on both parties immediately upon execution and which are expressions of intent subject to negotiation in the definitive agreement.

Example Language

This Letter of Intent is non-binding in all respects except for the following provisions, which shall be legally binding upon execution by both parties: (i) Section 5 (Exclusivity Period); (ii) Section 7 (Confidentiality); (iii) this Section 9; and (iv) Section 10 (Governing Law and Dispute Resolution). All other terms set forth herein are expressions of the parties' current intentions and do not constitute a binding agreement. Neither party shall have any legal obligation to complete the proposed transaction until a definitive Asset Purchase Agreement has been duly executed by both parties.

💡 Never allow the purchase price, earnout structure, or deal terms to be characterized as binding at the LOI stage — doing so removes your leverage to renegotiate based on due diligence findings. The only sections that should be binding are exclusivity, confidentiality, governing law, and the binding/non-binding clause itself. Some sellers' attorneys will try to make the 'no material adverse change' or 'good faith negotiation' language binding — resist this.

Key Terms to Negotiate

Revenue Quality Threshold and Retainer Percentage Floor

Before finalizing the purchase price multiple, negotiate a written representation in the LOI that at least 70% of trailing twelve-month revenue is derived from recurring monthly retainers — not one-time campaign builds, list migration projects, or platform setup fees. If due diligence reveals the retainer percentage is materially lower, the multiple should compress accordingly. Email marketing agencies frequently have lumpy revenue from annual campaign launches or seasonal ecommerce clients that can inflate a single year's EBITDA without representing sustainable recurring income.

Client Concentration Cap and Earnout Trigger Mechanics

Negotiate a specific client concentration representation (no single client above 25% of revenue) and define precisely how the earnout will be calculated if the top client churns post-close. The earnout measurement should use dollar-weighted retainer revenue as of the closing date as the baseline, not a projected or forward revenue figure. Specify whether partial client churn (a client reducing their retainer by 40%) counts as full churn for earnout purposes, and include a floor below which the earnout is zeroed out versus prorated.

Key Employee Retention as a Closing Condition

Identify the two or three employees — typically lead strategists, senior account managers, or the head of deliverability — whose departure would most damage client relationships and service quality. Negotiate their execution of employment agreements with retention bonuses funded from the purchase price as a hard condition to closing, not a best-efforts obligation. For agencies where the founder is the only relationship holder, this negotiation is less about employees and more about structuring the seller's post-close consulting engagement with financial incentives tied to client retention.

Platform and ESP Account Transferability

Klaviyo, HubSpot, and Salesforce Marketing Cloud agency partner accounts are frequently held in the founder's personal name or email address, and partner tier status is tied to the agency entity's performance metrics. Negotiate upfront whether these accounts are transferable under an asset purchase, what the platform's consent process requires, and whether the partner tier resets to zero after a transfer. If requalification would take 12+ months, this materially affects the agency's lead generation pipeline and should be reflected in the purchase price.

Seller Note Standby Period and Earnout Interaction

If the deal is SBA-financed, the lender will require the seller note to be on full standby (no payments of principal or interest) for 24 months post-close. Negotiate the interaction between the standby period and the earnout payment schedule — sellers should not be in a position where both the seller note and earnout payments are blocked simultaneously for two years. Structure earnout payments as separate obligations not subject to the SBA standby restriction, which is achievable with careful document drafting reviewed by an SBA-experienced attorney.

Common LOI Mistakes

  • Accepting the seller's revenue figure at face value without separating retainer, project, and performance-based income before submitting the LOI — email marketing agencies routinely include one-time platform migration projects or email list audits in MRR calculations, overstating the sustainable recurring revenue base and leading to a purchase price the cash flows cannot support post-close.
  • Omitting platform transferability from the LOI conditions to closing — buyers who discover mid-due-diligence that the agency's Klaviyo Elite Partner status is non-transferable or requires a 12-month requalification period often face a binary choice between walking away from the deal or accepting a material reduction in the asset they paid a premium to acquire.
  • Using a 30-day exclusivity period under pressure from the seller's broker — SBA-financed acquisitions of email marketing agencies realistically require 60–75 days from LOI to close, and a 30-day exclusivity window forces the buyer into a rushed due diligence process that misses client churn patterns, employee retention risks, and revenue quality issues that only become visible when reviewing 24 months of data.
  • Failing to negotiate specific transition consulting obligations in the LOI before the seller loses negotiating incentive post-signing — sellers who agree only to 'reasonable transition assistance' in the LOI often interpret that as 30 days of email responses, leaving the buyer without the client introductions and strategic knowledge transfer needed to retain the accounts that justified the purchase price.
  • Treating the earnout as a seller protection rather than a buyer protection — earnouts in email marketing agency acquisitions exist to bridge a valuation gap created by client retention uncertainty, not to reward the seller for hitting growth targets. Structuring the earnout around revenue growth above baseline (rather than retention of existing baseline retainer revenue) misaligns incentives and can reward a seller who lands one large new client while losing three existing ones.

Frequently Asked Questions

What multiple of EBITDA should I offer in the LOI for an email marketing agency?

Email marketing agencies in the $1M–$5M revenue range typically trade at 3x–5.5x adjusted EBITDA, with the upper end reserved for agencies demonstrating 70%+ retainer revenue, net revenue retention above 110%, documented SOPs, diversified client bases, and platform specialization such as Klaviyo Elite Partner status. In the LOI, anchor your offer to a specific TTM adjusted EBITDA figure and state the multiple explicitly. A 3.5x–4.0x offer is defensible for agencies with month-to-month contracts and founder dependency; you can justify 4.5x–5x for agencies with annual contracts, low churn, and a documented account manager layer that handles client relationships independently of the owner.

Should the LOI be structured as an asset purchase or stock purchase for an email marketing agency?

The majority of lower middle market email marketing agency acquisitions use an asset purchase structure, particularly when SBA financing is involved. Asset purchases allow the buyer to cherry-pick which liabilities they assume, achieve a stepped-up tax basis on acquired assets, and avoid inheriting unknown obligations from the seller entity. The primary complication is contract assignment — client agreements, platform partner accounts, and software subscriptions must be individually assigned or novated, which requires consent from each counterparty. For agencies with a Klaviyo or HubSpot partner designation, confirm the platform's assignment policy before choosing structure. Stock purchases simplify contract continuity but expose the buyer to historical liabilities and are less favorable from an SBA underwriting perspective.

How should client retention risk be handled in the LOI if most contracts are month-to-month?

Client retention risk in a month-to-month agency is best addressed through a combination of an earnout tied to retained retainer revenue and a robust transition consulting obligation. In the LOI, specify an earnout baseline equal to trailing retainer revenue as of closing, define the retention percentage threshold that triggers earnout payments (typically 85–90% retention at the 12-month mark), and require the seller to provide a minimum 90-day transition period with personal client introductions. Additionally, negotiate a representation that the seller has no knowledge of any client intention to reduce or cancel retainer services — and make this representation a closing condition that survives into the definitive agreement.

Can I get SBA financing to buy an email marketing agency, and does the LOI need to mention it?

Yes — email marketing agencies are SBA 7(a) eligible businesses when structured as asset purchases from operating entities with at least two years of operating history and positive cash flow sufficient to service debt. SBA loans can cover 80–90% of the purchase price (up to $5M), making them the most common financing tool for lower middle market agency acquisitions. Your LOI absolutely should reference the SBA financing condition — stating that the transaction is contingent on Buyer obtaining SBA 7(a) financing on acceptable terms protects you if the loan is not approved. Notify the seller at LOI execution that SBA approval typically adds 60–90 days to the timeline, so they set realistic expectations for closing.

What due diligence items specific to email marketing agencies should the LOI reference?

Beyond standard financial and legal due diligence, the LOI should explicitly reference: (1) client contract terms and 24-month churn history to assess net revenue retention; (2) access to email service provider accounts (Klaviyo, HubSpot, Mailchimp) to verify account ownership, deliverability metrics, and subscriber list health; (3) documentation of agency partner status with ESPs and the terms of those partnerships including lead referral volume; (4) team structure and identification of key person dependencies, including whether the founder is the primary point of contact for top accounts; and (5) a revenue quality breakdown separating retainer, project, and performance income. Each of these items addresses a specific risk that is unique to email marketing agencies and that generic due diligence checklists will miss.

How long should the LOI negotiation and due diligence process take for an email marketing agency acquisition?

From the date of signing the LOI to closing, most email marketing agency acquisitions take 90–120 days when SBA financing is involved, or 60–75 days for all-cash transactions. The LOI negotiation itself — from initial offer to signed LOI — typically takes 1–2 weeks if both parties are motivated. Budget 45–60 days for due diligence, 30–45 days for SBA lender processing concurrent with due diligence, and 2–3 weeks for definitive agreement drafting and closing logistics. Deals that drag past 120 days from LOI signing face elevated client and employee leak risk — if your exclusivity period expires before closing, renegotiate an extension rather than letting it lapse without a formal agreement.
