A strong cover letter close is three short sentences:

  1. Reaffirm interest in the role.
  2. State one specific reason you're the right fit.
  3. Ask for the next step.

Then sign off and add contact info. The close should be its own paragraph, two lines max.

Template

[Reaffirm interest.] [Specific fit.] [Ask.]

Best regards, [Name] [Phone] | [Email] | [LinkedIn URL]

Example

I'd love to bring my experience scaling pricing infrastructure to the [Role] at [Company]. Given the work I led at Acme on a similar system serving 50K customers, I'm confident I could contribute quickly. Open to a call when you have time.

What kills a close

  • "Thank you for your consideration!" as the entire close (filler).
  • Re-summarizing the cover letter (they just read it).
  • "Please don't hesitate to..." (clichéd).
  • Multiple paragraphs of pleasantries.

Sign-offs

  • Best regards — modern professional, most common.
  • Sincerely — traditional, fine.
  • Thanks — fine, slightly informal.

Avoid: "Cheers," "Yours truly," "Warmly."

P.S. (optional)

A short P.S. can highlight one extra signal:

P.S. I built [a small relevant project / wrote a relevant article]. Happy to share if useful.

Use it once, never twice. Skip if the letter is already strong.

The bigger pattern

A polished close on one cover letter matters less than tailoring fifty cover letters. Sorce auto-generates and tailors a cover letter per application — 40 free swipes a day, AI agent applies. The close is consistent and tight on every one.
