How to Write an RFP Response Cover Letter That Evaluators Remember

Responding to a request for proposal (RFP) is mostly about compliance: answering every question, in the right format, by the deadline. The cover letter is the one place where you get to speak directly to the people making the decision.

Many companies waste it on boilerplate: “We are pleased to submit our response and look forward to the opportunity.” Evaluators have read that sentence hundreds of times. A strong cover letter does something more useful: it tells them, in one page, why you are the right choice for their specific situation.

What The Cover Letter Should Do

• Show you understand their problem, in their words.
• Summarise your fit against their most important criteria.
• Highlight one or two differentiators, with evidence.
• Confirm compliance and point to key sections.
• Name a contact and signatory.

Keep it to one page. Check the RFP for any rules on cover letters; some prohibit them or limit their length.

Lead With Their Priorities

Before:

Acme Solutions is a leading provider of innovative technology services with over 20 years of experience. We are pleased to submit our response to your RFP and believe we are uniquely positioned to deliver exceptional value.

After:

Your RFP sets out three priorities: moving 40,000 patient records with no service interruption, meeting NHS data security standards, and keeping clinic staff training under two hours. Our response shows how we have done exactly this for three regional health trusts since 2023, with no unplanned downtime, and a training programme that averaged 90 minutes per clinic.

The second version mirrors their criteria, then gives proof.

Use Evidence, Not Adjectives

“Industry-leading”, “best-in-class” and “innovative” mean nothing to an evaluator scoring against criteria. Specific results, references and certifications do. If you mention a client, make sure you have permission.

Signpost The Response

Evaluators are busy and often score sections separately. Help them:

Section 4 covers our migration approach and timeline. Section 6 details our security certifications. Pricing is in Appendix B as requested.

Address Risks Honestly

If there is an obvious concern, such as being a smaller supplier or proposing a different approach, address it briefly and confidently. Evaluators notice what you avoid.

Public Sector Rules

Public procurement often has strict rules on format, communication and evaluation, and anything outside the specified structure may not be scored. In the US, federal procurement follows the Federal Acquisition Regulation, and other countries have equivalent rules. Read the instructions twice.

A Context For Proposal Writing

A Wrivio Context for RFP cover letters could say:

Rewrite this as an RFP response cover letter. Confident, precise and specific, one page, no marketing adjectives such as leading, innovative or best-in-class. Start with the buyer’s stated priorities, then our evidence for each, then where to find key sections. Keep every number, client name, date, certification and section reference exactly as written. Do not add claims, references or commitments that are not in the original.

Press Ctrl+Shift+Space, paste your draft, and check every number and reference against the main response. Inconsistencies between the cover letter and the body cost points. See how to write a proposal executive summary and how to write a case study people believe.

Common Questions

Is a cover letter required for an RFP response?

Not always. Some RFPs request one, some forbid it, and some ignore it in scoring. Follow the instructions. When allowed, a strong one helps evaluators frame the rest of your response.

How long should an RFP cover letter be?

One page. Anything longer belongs in the executive summary or the response itself.

Who should sign the cover letter?

Someone with authority to commit the company, usually a director or executive, and named as the contact if the RFP asks for one.

Can I reuse a cover letter across RFPs?

Reuse structure, not content. Evaluators can tell when a letter was not written for them, and generic letters waste the one page where you can stand out.
