Client Said the Check Is in the Mail: What to Email Next

“It's in the mail” or “Payment went out last week” is a promise, not a payment. If nothing has arrived, the next step is a short, friendly email that turns the promise into specifics: when it was sent, how, and a reference you can trace—all in writing.

Send this once the expected arrival date has passed. Replace every [bracket] before sending.

Hi [Client Name],

Thanks for letting me know payment for invoice [Invoice #] ([Amount]) was sent on [Date They Mentioned / "recently"]. It hasn't arrived on my end yet, so I want to make sure it didn't go astray.

Could you reply with:
1. The date it was sent
2. The method (check, ACH, wire, card, etc.)
3. A check number, transaction ID, or tracking reference

If it was a check, please confirm it went to: [Your Mailing / Remit-To Address].
If it's easier, you can also pay here and I'll void any check that shows up later: [Payment Link]

Thanks for helping me track it down,
[Your Name]
[Your Business]

If you get no details within a week

Hi [Client Name],

Following up—payment for invoice [Invoice #] ([Amount]) still hasn't arrived, and I haven't received a send date or reference number.

Could you confirm in writing by [Date] either the payment details or the date it will be sent? If the original payment can't be traced, a replacement via [Payment Link] is the fastest fix.

Why asking for specifics works

• A real payment has a date, method, and reference. Asking for them is neutral—no accusation needed.
• If something genuinely got lost, the details help AP trace or reissue it quickly.
• If the promise was a stall, specifics are hard to dodge and the written record helps later.
• Offering a payment link gives them a one-click way out instead of waiting on mail.

What not to do

• Do not accept another vague “should be there soon” without a date.
• Do not call the client a liar; assume it's a mix-up until the details say otherwise.
• Do not keep doing new work while a promised payment is untraceable—see the pausing-work guide below.
• Do not let the promise live only in a phone call; recap it in email.
