Collection letter template

The short answer
A dated, delivered first notice is the record you want before you hand a debt to a collections agency. Send it Certified with electronic Return Receipt, $14.99 all-in: USPS records when it was mailed and when it was signed for. Preview the exact pages free. This template is not legal advice.
The math
The math on one certified letter.
| Option | Cost | Your time |
|---|---|---|
| paperplane, Certified + Return Receipt | $14.99, all in | About two minutes |
| At the counter | USPS fees, plus printing, an envelope and the trip | About ten minutes at the counter, plus the drive and the line |
USPS charges the same fees whoever hands the letter over. The difference is the trip, the form and the slip you keep for a year.
A past-due invoice buried in email gets ignored. A physical letter reads as a genuine escalation, and it gives you a delivery-verified paper trail — useful if the account eventually goes to a collections agency or small claims court.
First notice vs. final notice
For a first notice, some businesses start with plain First-Class ($0.99) and keep the tone professional. Save Certified + Return Receipt for a final notice before referring the account to collections — that is when proof of exactly when it was received starts to matter.
How it works
- Open the template, add the invoice number, amount, and due date.
- Pay $14.99 (Certified + Return Receipt) — mailed the next business day.
- Keep the delivery record if the account escalates further.

Questions before you send
Why not go to the post office myself?
You can, and if your time is free it costs less. USPS charges the same fees whoever hands the letter over; paperplane does not replace the post office, it replaces the trip. The mailing record comes from USPS, not from us. $12.99 covers the printing, the envelope, PS Form 3800, a USPS address check before you pay and a handoff the next business day. For a letter you already know how to send, the counter is a fine choice.
What if they refuse the letter?
USPS tracking records what happened to it, including refused or unclaimed. You still have the mailing record. Rules on what that means vary, so check with your court or an attorney if a deadline depends on it.
If something goes wrong, do I pay?
If we cannot mail the letter, the hold on your card is released and you are not charged. If a letter fails after your card is charged, you are refunded automatically and in full.
Why send a formal letter instead of just emailing?
A physical letter reads as a genuine escalation, not another email in a crowded inbox, and it creates a delivery-verified paper trail — useful if the account later goes to collections or small claims.
What should a first collection letter include?
The invoice number, amount, and due date; a specific new deadline; and an offer to discuss if there is a dispute or hardship. Keep the tone professional — save firmer language for a follow-up notice if this one is ignored.
Certified Mail or plain First-Class?
For a first notice, some businesses start with First-Class ($0.99) and reserve Certified with Return Receipt ($14.99) for a final notice before referring the account to collections — the delivery proof matters most closer to that decision.
