How to Write an Email Requesting a Client's Approval on a Retainer Agreement

A retainer agreement is the foundation of a stable, ongoing client relationship. It guarantees you consistent work and income, while giving your client priority access to your expertise. But before any work begins, you need that agreement signed, approved, and returned. The approval email you send can be the difference between a quick signature and a long, awkward silence. A poorly worded request can make the client feel pressured or confused, while a clear, professional invitation builds confidence and speeds up the process. This guide provides a tone-focused approach and ready-to-use templates to help you request a client's approval on a retainer agreement with clarity, respect, and effectiveness.

Why You Need a Clear Retainer Approval Process

A retainer agreement is more than a contract—it's a commitment to a recurring service relationship. Getting it approved and signed sets the tone for the entire engagement. A clear approval process shows your client that you are organized, transparent, and serious about the partnership. It also protects both parties by defining scope, payment terms, and expectations upfront. Without a signed retainer, you risk scope creep, payment disputes, and confusion about availability. By proactively requesting approval and making the process easy, you demonstrate professionalism and set the stage for a smooth, long-term collaboration.

Pro Tip: Always send the retainer agreement in an editable format (e.g., Word or Google Doc) along with a PDF for reference. This gives the client flexibility to review and make notes directly on the document.

Common Mistakes That Delay Retainer Approvals

Even a well-crafted retainer can sit unsigned if your approval request falls short. Avoid these common pitfalls to keep the process moving:

  • Sending the agreement without a summary: A long legal document can be overwhelming. Provide a bullet-point summary of key terms (scope, fee, duration, termination) so the client knows what they're signing.
  • Not specifying a deadline: Without a clear "please sign by" date, clients may set the document aside indefinitely. Give them a reasonable deadline (e.g., 5–7 business days).
  • Using overly formal or intimidating language: While the agreement itself may be legal, your email should be warm and approachable. Avoid legalese in the request.
  • Failing to highlight the benefits: Remind the client how the retainer benefits them—priority support, guaranteed availability, cost savings—to reinforce their decision.
  • Not offering a call to discuss: Some clients may have questions. Invite them to schedule a quick call to go over any concerns.

Polite Email Templates to Request Retainer Agreement Approval

Below are two templates: one for a standard initial request and one for a follow-up. Each includes subject line options and placeholders. Customize the bracketed sections before sending.

⚠️ Warning: Never pressure a client to sign without giving them adequate time to review. Rushing can lead to buyer's remorse or legal issues. Always allow at least 3–5 business days for review, and offer to address any concerns.

Best Practices for Securing a Signed Retainer

Beyond the email, these habits will help you get retainer agreements signed quickly and professionally:

  • Personalize the agreement: Tailor the retainer to the client's specific needs. A generic template may not address their unique concerns, making them hesitant to sign.
  • Use electronic signatures: Platforms like DocuSign, HelloSign, or PandaDoc make it easy for clients to sign without printing or scanning. Include a link to your preferred e-signature tool.
  • Set a clear start date: Specify when the retainer takes effect once signed. This gives the client a tangible milestone and motivates them to act.
  • Follow up with a thank-you: Once signed, send a warm thank-you email and confirm the start date. This reinforces the positive relationship.
  • Keep a record: Store the signed agreement securely and share a copy with the client for their records. This prevents disputes about what was agreed.

What to Do If You Don't Hear Back

If you've sent a follow-up and still haven't received the signed agreement, don't panic. Here's a step-by-step plan to move things forward:

  • Send a second follow-up (if needed): A third email with a slightly more direct tone, but still polite. Mention that you need the signed agreement to proceed with the work and that you're open to adjusting any terms.
  • Make a phone call: A brief call can often break the silence. Ask if they received the emails and if they have any questions. Often, the issue is simply that they forgot or were too busy.
  • Offer a virtual review session: Schedule a short video call to walk through the agreement together. This can speed up approval by answering questions in real time.
  • Check with the right contact: Sometimes the person you're emailing isn't the final decision-maker. Ask if there's someone else in their organization who needs to review the document.
  • Consider a verbal agreement to start: If the client is eager to begin but the paperwork is delayed, you may agree to start work with a verbal confirmation, pending the signed agreement within a week. This should be done cautiously and only with trusted clients.

Throughout this process, remain professional and understanding. The goal is to get the signature, not to create tension. A patient, supportive approach often yields the best results.

Frequently Asked Questions

Q: How long should I give a client to review and sign a retainer agreement?
A: Typically, 5 to 7 business days is reasonable. For large corporations with lengthy internal approval processes, you may need 10–14 days. Always state a specific deadline in your email and remind them a few days before.

Q: What if the client requests changes to the retainer agreement?
A: This is common. Review their proposed changes carefully and discuss them openly. You can accept, reject, or negotiate. Once both parties agree, update the document and resend it for final approval. Keep a record of all revisions.

Q: Is it better to send the retainer agreement as a PDF or a Word document?
A: Send both. PDF is best for reading and signing electronically, while Word (or Google Docs) allows the client to edit if they want to suggest changes. Provide clear instructions on which version to use for signing.

Q: Should I ask for a deposit or upfront payment along with the signed retainer?
A: It's common to request the first month's retainer fee or a deposit upon signing. If you do, mention that clearly in your approval request email so the client knows what to expect.

Q: Can I start work before the retainer is signed?
A: It's generally risky, as you have no formal agreement in place. However, for trusted clients, you might start with a limited scope or a single deliverable while the paperwork is being finalized. Always state that this is a one-time exception.
