How to Write a Polite Reminder Email (Friendly and Gentle Reminder Examples)

A polite reminder names the specific thing, the date, and the one action you need, and makes that action easy to do. The politeness comes from clarity and a reason, not from apologising or padding the message with softeners.

This post is about reminding someone to do something: approve a request, send a document, meet a deadline, turn up to an event. If you are chasing a reply to an email that has gone quiet, that is a different problem, and this guide to following up after no response covers it. For unpaid invoices, see our payment reminder templates, because money changes the tone you need.

What a good reminder includes

Reminders get ignored when they are vague. "Just checking in on this" asks the reader to work out what "this" is, find the original email, and decide what you want. A reminder that does that work for them gets done faster. Include:

• What is needed. One sentence, specific enough that they could act without opening anything else.
• By when. A real date, not "soon" or "when you can".
• Why the date matters. A short reason: a meeting, a launch, a filing, a booking. People act on deadlines that have a reason behind them.
• The link or attachment again. Do not make them dig through their inbox for the original.
• An easy out. A line such as "if this is now with someone else, just point me to them" removes friction and avoids the awkwardness of a reminder landing on the wrong desk.

Keep it to a few lines. A reminder is not the place for a second pitch or a recap of everything that has happened so far.

"Friendly reminder": does it sound passive-aggressive?

Often, yes. Many people read "friendly reminder" and "gentle reminder" as mildly passive-aggressive, because the word is doing the work that the tone of the message should be doing. It tends to land worst on a first reminder, and worst of all when it goes to someone senior to you. In a low-stakes setting, such as a club, a friend or a colleague you know well, it is perfectly fine.

If you want the message to sound warm without the loaded phrase, say what you need and let the clarity carry the courtesy. Some alternatives that read more neutrally:

• "A quick reminder that {thing} is due on {date}."
• "Heads-up: {thing} is due on {date}."
• "Just flagging that {thing} closes on {date}."
• "Following up on {thing}, which I need by {date}."
• "As discussed, {thing} is due on {date}."

Two other phrases come up a lot. "Kind reminder" and "kindest reminder" are common in some varieties of English, but many British and American readers find them unusual, so "a quick reminder" is the safer choice when you write to someone abroad. "Courtesy reminder" is formal and slightly impersonal; it suits organisations, account notices and anything where you are one of many people being contacted.

Reminder email templates

Each template below follows the same structure: the thing, the date, the action, the reason. Replace the braces with your own details and cut anything that does not apply.

1. Reminder for approval

Approvals often stall because the approver is busy, not because they object. Make approving take one reply.

2. Reminder to send a document or information

When you are waiting on something from another person, tell them exactly what you need and where it goes. This is also the cleanest answer to the question of how to remind someone to send you something without sounding impatient.

3. Deadline reminder (before the deadline)

Send this while there is still time to act. A reminder on the day itself is a complaint, not a reminder.

4. Reminder to your manager or boss

Reminding someone senior works best when you remove the effort from their side. Give them the decision, or the draft, and say what happens if the date passes. Do not apologise for asking; you are protecting their time as well as yours.

5. Event or meeting reminder

6. Second reminder when the first got no action

A second reminder can be firmer, and it should still be polite. State the consequence plainly, offer a way to hand the task off, and keep the tone level. If you are not sure how many to send, this guide on how many follow-up emails to send gives sensible limits.

Reminder email subject lines

A reminder subject line should state the thing and the date, so it is useful even if the email is never opened. Avoid "Reminder" on its own and anything in capitals.

• Approval needed by {date}: {project name}
• {Document} needed by {date}
• {Task} due {day and date}
• Quick reminder: {event} on {day} at {time}
• Decision needed on {topic} by {date}
• Still needed: {thing} by {date}
• Your {form or booking} closes {date}
• One thing outstanding on {project}
• Can you confirm {thing} by {day}?

When to send a reminder

These are sensible defaults, not rules. Adjust them to how urgent the task is and how well you know the person.

• Leave enough lead time. For a deadline, send the first reminder while the person still has room to do the work properly, not in the last hours.
• Send a second one closer to the date. One reminder well ahead and one a short while before the deadline is usually enough.
• Do not remind daily. Repeating the same message every day turns a reasonable request into pressure. If something has gone unanswered through two reminders, change the approach: offer a call, ask whether someone else owns it, or escalate respectfully.
• Avoid late Friday and early Monday. A reminder is easiest to act on when it arrives during someone's working day with time to deal with it.

For more on spacing, when to follow up goes through timing in detail, and how to follow up without being annoying covers the tone side.

One caveat on that: an open means the email rendered on someone's screen, not that it was read or understood. An unopened email is a good reason to re-send. An opened one only tells you the message arrived and rendered. It is not a reason to assume the person is ignoring you; an open is not intent explains why.

Know whether your reminder is needed

MailSenseAI is a free Chrome extension that works inside Gmail. For each thread it shows whether your email was opened, clicked or replied to, so you can tell whether to re-send, wait, or write a reminder at all. When you do need to chase, it can draft an AI follow-up for you to edit and send. It never adds a footer to your emails on any plan, and tracking is free and unlimited.
