How do I remind a customer who hasn't signed yet, without being annoying?

Most unsigned documents aren't a sign the customer changed their mind, they're a sign the document got buried under everything else in someone's day. A well-timed reminder, not a daily nag, usually fixes this on its own. A running list of which contracts are still unsigned makes the timing much easier to follow.

Reminder timing that works

A useful cadence I'd recommend for most business documents:

• Day 2 to 3: first gentle reminder. A meaningful share of people who sign at all do so within the first couple of days, so this first nudge is really just making sure the document didn't get lost in a crowded inbox, not assuming they're avoiding it.
• Day 5 to 7: second reminder, slightly more direct, especially if there's a real deadline tied to the document (a job start date, an event date, a price that changes).
• Day 10 to 14: a personal check-in rather than another automated nudge, a quick call or a direct message asking if anything's blocking them, since at this point an automated reminder alone usually isn't going to move things.
• Beyond two weeks with no response: treat it as a stalled deal rather than a pending one, and decide deliberately whether to keep pursuing it or move on, rather than letting reminders quietly continue indefinitely with no real plan behind them.

Reminding daily, or within hours of sending, reads as pushy to most people and rarely speeds anything up, since the usual reason someone hasn't signed is that they haven't gotten to it yet, not that they're weighing a decision that a faster nudge would resolve. The same timing logic applies to quotes, as in an automatic follow-up three days after a quote.

Message templates (plain language)

Keep reminders short and specific, never vague or guilt-tilted. A few templates that work well across most situations:

First reminder: "Hi [name], just making sure this didn't get buried, here's the link to sign [document name] again: [link]. Let me know if anything's unclear."

Second reminder, with a real deadline: "Hi [name], following up on [document name], I need this signed by [date] to [reason, e.g. "keep your start date on schedule" or "lock in the current price"]. Here's the link again: [link]. Happy to answer anything first if that's what's holding it up."

Personal check-in, past the automated stage: "Hey [name], noticed [document name] is still sitting unsigned, is there anything about it you'd like to go over before signing, or any part that needs changing?"

If you can see the link's been opened but it's still unsigned: "Hi [name], I noticed you had a chance to look at [document name], happy to clarify anything in it before you sign, or adjust something if needed." This version explicitly invites a question rather than assuming the delay is just forgetfulness, which matters once you know they've actually read it and still haven't acted.

Notice none of these guilt-trip or imply the customer did something wrong. The most common actual reason a document sits unsigned is simply that it's not top of mind, not resistance, and a message that assumes the worst tends to put people on the defensive rather than move them to act.

Auto reminders and expiry

QuickSigner, a web-based e-signature tool, includes automatic reminders from its Business plan upward, $5 a month per user billed annually, which handles the Day 2-3 and Day 5-7 nudges above without you writing or sending anything manually. This is genuinely one of the more valuable features once you're sending more than a handful of documents a month, since manually tracking who's been reminded and when becomes real overhead past a certain volume. Set it once per document type and let it run, reserving your own personal follow-up for the cases that actually stall past the automated stage.

Pairing reminders with an expiry date (covered in full in my guide to signing deadlines) sharpens this further: a document with a visible deadline creates a real reason to act now rather than "eventually," and the final reminder before expiry tends to be the one that actually gets a response when earlier ones didn't.

Why documents actually sit unsigned in the first place

Understanding the real reason behind the delay changes what kind of reminder actually helps. In my experience the most common causes, roughly in order, are: the email genuinely got buried under other messages, the person meant to review it properly before signing and hasn't found a quiet moment to, something in the document raised a question they haven't gotten around to asking, or, less often than people assume, they're having second thoughts about the deal itself. The first two causes respond well to a simple, friendly reminder. The third needs a message that explicitly invites a question rather than just resending the link. The fourth needs an actual conversation, not another reminder at all, since no amount of automated nudging resolves genuine hesitation about the deal. Reading which category you're likely in before firing off another reminder saves you from repeating a message that was never going to work. There is a fuller list in why customers do not sign.

A quick worked example

Say you sent a service agreement to a new client on a Monday. By Wednesday (day 2), it's still unsigned, so you send the friendly first-reminder template above. By the following Monday (day 7) with still no action, you check whether the link's even been opened: if it hasn't, the issue is likely delivery, confirm the email address and resend, possibly through a different channel like a text. If it has been opened but not signed, send the second template, direct and specific, mentioning any real deadline. If another week passes with no response at all, that's the point for a personal call rather than a third written reminder, since a document that's been opened and read twice without being signed usually means something specific is holding the person back, and only a real conversation surfaces what that actually is.

Common mistakes with reminders

• Reminding too often. More than roughly once every few days reads as pressure, not helpfulness, and can make people avoid opening the message at all rather than dealing with it.
• Using the exact same message every time. A customer who's seen the identical automated reminder three times in a row tends to tune it out. Vary the wording, or switch from automated to a personal note, once you're past the first reminder or two.
• Not checking whether they actually opened it. Most e-signature tools show whether a link was opened, not just sent. If it's never been opened at all, the issue might be delivery (check spam, confirm the email address) rather than reluctance to sign.
• Ignoring a stall past two weeks instead of addressing it directly. Letting reminders run indefinitely without a real conversation usually means the deal has quietly died and nobody's acknowledged it yet.

How I'd approach this

The single biggest improvement I see when a business switches from manual follow-up to automatic reminders isn't speed, it's consistency. Manual reminders depend on someone remembering to check and follow up, which slips during a busy week. Automatic reminders fire the same way every time regardless of how busy anyone is. For businesses sending contracts or onboarding documents regularly, I set this up as part of the broader client flow, reminders, expiry, and what happens automatically once a document's finally signed, rather than leaving it as a manual task someone has to remember. Get in touch if that's worth building properly for your business, and I'll tell you honestly if a simpler setup covers what you actually need instead.
