How do I write a payment reminder email?
How to write a payment reminder email that gets paid
Short answer
A payment reminder email should be brief, specific, and non-confrontational. Include the invoice number, amount due, original due date, and a direct payment link in every message.
**Subject line formula:** Invoice #[NUM] — [Amount] due [Date] — quick reminder
**Body structure:** 1. One-line opener: "I hope you're well. I wanted to follow up on invoice #[NUM] for $[amount], which was due on [date]." 2. Payment details: invoice number, amount, due date, and a clickable payment link. 3. Soft close: "Please let me know if you have any questions or if something is preventing payment." 4. Signature with your phone number.
**Timing sequence that recovers the most invoices:** - Day 0 (due date): Automated reminder — polite, no penalty language. - Day 3: First follow-up — same tone, confirm invoice received. - Day 7: Second follow-up — add note about late fee if applicable. - Day 14: Final written notice — firm, reference next steps. - Day 21+: Phone call or automated voice outreach.
**What NOT to do:** - Don't apologize for asking for payment. - Don't send a vague "just checking in" — always include invoice details. - Don't threaten legal action before day 30 unless a written agreement permits it.
Most overdue invoices are paid within 3 reminder emails. If payment hasn't arrived after the phone-call stage, consider automated AI voice follow-up (Syntharra automates this entire sequence).
