Collections email templates — 10 escalating drafts

A chronological escalation sequence — from a friendly day-0 reminder through a day-90 final demand. Every template uses Mustache placeholders so you can drop in your own customer, invoice, and amount details. These are marketing drafts, not legal advice: have your attorney review stage 4 and 5 copy before sending.

Stage 1Day 3Friendly reminder

Reminder: invoice {{invoiceNumber}} is {{daysPastDue}} days overdue

Send 3 days after the due date, before late fees kick in. Assumes goodwill.

Show email body
Hi {{customerName}},

Hope you are doing well. Our records show invoice {{invoiceNumber}} for {{amount}} went past due on {{dueDate}}, so it is now {{daysPastDue}} days out.

No stress if it is already on the way — this note often crosses payment in the mail. If it slipped through on your side, a quick reply letting me know when to expect it would be great. I am happy to resend the invoice, split the balance across two payments, or take payment over the phone if that makes it simpler.

Thanks for your attention, and apologies in advance if payment and this email crossed paths.

Best,

Stage 3Day 21Formal request

Invoice {{invoiceNumber}} — 21 days past due, needs resolution

Send three weeks past due. Shifts from reminder to formal request for payment.

Show email body
{{customerName}},

This is a formal notice that invoice {{invoiceNumber}} for {{amount}} is now {{daysPastDue}} days past due. Multiple reminders have gone unanswered.

I want to assume this is an oversight. If so, please remit payment in full by the end of this week, or contact me today to arrange a payment plan. Our standard plan spreads the balance across three equal monthly installments with the first due immediately.

If there is a dispute about the amount or the work performed, I need you to put that in writing this week. Continuing to ignore the invoice without raising a dispute is not a workable path for either of us.

If I do not hear from you within seven days, we will move to the next step of our collections process.

Frequently asked questions

When should I send each template?

Each template is labeled with the days-past-due it is designed for. The default cadence is day 0, day 3, day 7, day 14, day 21, day 30, day 45, day 60, day 75, and day 90 — but adjust to your own net terms and industry norms.

Are these templates legal to send?

These are marketing drafts, not legal advice. Collections email has fewer restrictions than collection calls under the FDCPA, but state consumer protection laws (and FDCPA for third-party collectors) still apply. Have your attorney review the stage 4 and 5 templates before you use them verbatim.

How do I personalize the placeholders?

Every template uses Mustache-style tokens like {{customerName}}, {{invoiceNumber}}, {{amount}}, {{daysPastDue}}, {{dueDate}}, {{yourName}}, and {{yourCompany}}. Replace the tokens inline, or paste the template into your email tool and map the fields to your own merge variables.

Can I use these as is, or do I need to change the wording?

You should customize. Copy that sounds generic loses impact fast — change the greeting style, your signoff, and any phrasing that does not fit your industry. Treat the sequence as a skeleton, not a finished product.

What happens if the customer still does not pay after template 10?

At 90 days past due, the practical next step is either an attorney demand letter, referral to an external collection partner, or small-claims court for smaller balances. Syntharra's automated voice cadence typically resolves 35–50% of these accounts before they reach that point — see our DSO calculator to model the impact.

Emails only get you so far.

Syntharra automates this entire sequence — and handles the call after 3 days past due. Connect your books once; we watch every invoice forever and recover before the balance ages.
