Collection Email Templates: What to Send at 15, 30, 60 and 90 Days Past Due

Four collection emails that each escalate something real, with the wording you can adapt, plus the reason most accounts receivable sequences quietly stop working after the second message.

By Sven Nelson, Chief Business Development Officer and Chief Marketing Officer, C2C Resources

When a claim arrives here, one of the first things we read is the email chain. It is usually long, usually polite, and it almost always tells the same story: four or five messages that say very nearly the same thing, sent weeks apart, each one slightly more frustrated than the last and none of them changing anything the customer actually has to respond to.

That is the real failure in most accounts receivable email. Not the wording, the sameness. A collection sequence works when every message moves the account somewhere new, so below are four templates covering 15, 30, 60 and 90 days past due, what each one is doing, and how to tell when email has stopped being the right tool.

Why send collection emails instead of letters?

The practical argument for email is the attachment. A surprising share of what looks like a refusal to pay is an invoice that never reached the person who approves it, and email is the only channel where you can resolve that in one message instead of one week.

The practical argument against email is that it is easy to ignore, which is true and is exactly why the sequence matters. A letter is an event. An email is one of two hundred things in somebody's inbox that morning, so it has to earn attention structurally rather than by tone.

Three things do that work: a subject line that names the invoice number and the amount, an attachment the reader can act on without replying to ask for it, and a visible change from the message before. Everything below is built on those three.

What should the day 15 collection email say?

The first message is not a collection email. It is a check that the invoice is in the system, and writing it as anything stronger costs you goodwill for no gain.

Two details matter more than the wording. The subject line carries the invoice number and the amount, which means the message is searchable and forwardable without being opened. And the last line offers to fix something, which gives a reader whose real problem is a mismatched purchase order a way to say so without admitting a delay.

Keep the invoice attached from here on. Every message in the sequence should be actionable on its own, because the person who eventually deals with it is often not the person you first wrote to.

What should the day 30 collection email say?

This is the message that most companies get wrong, usually by asking "could you provide an update" and accepting the answer. An update is not a commitment, and a commitment without a date is a decline that nobody wanted to say out loud.

Notice what changed. The subject line now states the age, the body references the previous email by date, and the question has only two acceptable answers: a date, or a reason. That gives you something to work with either way, which the first email deliberately did not.

If this message produces a date, write it down and follow up the morning after it passes. The accounts that quietly age past recovery are rarely the ones somebody decided to let go. They are the ones where the follow up date lived in one person's head.

What should the day 60 collection email say?

This is the single most underused move in accounts receivable, and the one that most often produces payment. Two months of messages to somebody without authority is not a collection process. It is a queue.

The history paragraph is the part worth copying. Three sentences, all factual, no adjectives: what was delivered, when it was invoiced, who was contacted and what came back. A senior reader can act on that in thirty seconds, and crucially it establishes that no dispute exists, which removes the easiest way to park the account for another month.

Keep the tone neutral. You are not accusing anybody of anything, and a senior contact who feels ambushed will hand it straight back down to the person who has already not paid you.

What should the day 90 collection email say?

Everything that makes this email work sits outside the email. If the deadline passes and nothing happens, you have taught the customer precisely what your dates are worth, and so has every colleague who inherits the account.

Four lines, no legal language, no capitals, no threat beyond the one thing you are actually going to do. Borrowed courtroom phrasing makes a message sound serious to the person writing it and sound like a template to the accounts payable staff who read these constantly.

Note the offer in the last paragraph. A message that leaves no honourable exit gets ignored by customers who could have paid something, and a partial payment plan that holds is a better outcome than a placement that recovers less. Our guide to what a final demand letter should say covers the posted version of this notice, which is worth sending alongside the email when the balance is large.

Why do collection emails get ignored?

It is worth being blunt about this, because most of the effort companies put into fixing their emails goes into rewriting the wording, which is the part that matters least.

• The recipient cannot pay you. Accounts payable clerks process what they are told to process. If nobody has approved the invoice, a clerk cannot conjure a payment date, and ten emails will not change that. This is what the day 60 escalation is for.
• The question has no wrong answer. "Any update on this?" can be answered with "we are looking into it" forever. "Which payment run is this going into?" cannot.
• It came from a system. Automated dunning from a no reply address is read as automated, filtered as automated, and ignored as automated. Use a real name and a real reply address.
• It is the same email again. If message four is message one with a firmer adjective, the reader learns that the sequence has no end. Something visible has to change each time.

Across roughly 25,000 claims a year, the email chains attached to placements are remarkably consistent on this. The wording is usually fine. The sequence almost never escalates.

Should collection emails replace phone calls?

Credit teams tend to drift toward email over time because it is lower friction and it feels productive. It is also where accounts go quiet, because nothing in an inbox obliges anyone to respond.

The combination is what works, and the order matters. Calling first means spending the call establishing what the invoice says. Emailing first means the document is already in front of them and the call can go straight to the only question that matters, which is when it will be paid. Our guide on how to make collection calls covers how to run that conversation and what to do with the common objections.

One more reason to keep calling: a phone conversation tells you things an inbox never will. You hear hesitation, you hear when the person is embarrassed, and sometimes you hear that the company has lost its controller and nobody is approving anything. None of that arrives by email, and all of it changes what you should do next.

When should you stop emailing and place the account?

The honest trigger is not an age in days, it is a change in the kind of answer you are getting. While a customer is still disputing, still promising, still asking for the delivery paperwork, you are in a conversation, and conversations sometimes produce payment. Once the replies stop being substantive, or stop arriving at all, you are not collecting any more. You are being managed.

We accept commercial claims from $1,000 to hundreds of thousands of dollars, under 120 days past due, and that number is the one worth planning around. Most placements we receive arrive closer to 180 days, typically after a fifth and sixth email that were never going to work. Clients typically recover 20 to 30 percent more with us than they did with their previous agency, and a meaningful part of that difference is simply that the accounts arrive earlier. Be wary of anyone quoting you a hard number instead: a suspiciously high published recovery rate usually means the agency is making it up.

There is also the case where placement is the wrong answer. If your past due balance is large because invoices go out with errors, because disputes sit unresolved for weeks, or because nobody owns the follow up, then an agency recovers some money and you meet the same problem again next quarter. That is an order to cash problem, and a first party accounts receivable program that runs this cadence in your own name fixes more of it than placement will. Getting the terms agreed in writing up front through an online business credit application prevents a good share of it from happening at all.

When the account genuinely has stopped responding, the next step is third party commercial debt collection, and the value of a fixed placement date is that it takes the decision out of the month it is hardest to make. If you want the posted versions of these messages, our guide to commercial collection letters has the full sequence with templates, and business payment terms covers the terms that decide how often you need any of this.

A note on where an account goes. It is worth using a certified commercial agency. C2C Resources is certified by the Commercial Law League of America, endorsed by the International Association of Commercial Collectors, carries a $500,000 surety bond, and holds collection licenses in the states that require them. Our collectors average twenty six years in this work, and we have collected commercial accounts in all fifty states since 2002.
