You sent the invoice two weeks ago, the deadline passed on Friday, and the client still hasn't paid or responded. A well-timed email reminder can be the difference between an awkward follow-up and a payment that quietly slips through the cracks, but most freelancers either wait too long or send something so vague it gets ignored. Getting reminders right matters even more once you're juggling multiple clients and due dates, which is why an effective email reminder needs the right timing, a clear subject line, and a structure that makes the ask obvious in the first two lines. This guide walks through exactly how to write one, from picking the send time to knowing when an automatic reminder can take the task off your plate entirely. For the bigger picture on getting paid on time, our complete invoice guide for small businesses covers the process end to end.
Here's how to put that into practice, step by step.

What makes an email reminder effective
An email reminder is a short, targeted message that prompts someone to complete an action they've already agreed to, like paying an invoice, confirming a meeting, or replying to a request. Effective reminders work because they're specific: they name the exact ask, the deadline, and what happens next, instead of vaguely nudging the recipient to "circle back."
There are two ways to send them. A manual reminder means you're writing and sending each message yourself, which gives you control over tone but takes time and is easy to forget. An automatic reminder is a message that a system sends on a schedule you set once, useful for recurring tasks like monthly invoices. Most freelancers end up using both, and knowing when to reach for each one is what separates reminders that get results from ones that get skipped over.
Step 1: Decide the right time to send your reminder
The right time to send a reminder is before the deadline matters, not after it's already passed. A reminder sent two or three days ahead gives the recipient time to act while the deadline still feels relevant, instead of arriving as an apology for something already missed.
Timing should match the stakes. A meeting confirmation might only need a same-day nudge, while an invoice often benefits from a reminder a few days before the due date and another shortly after, similar to the cadence covered in how to write effective payment reminders for clients. A document request usually sits somewhere in between, depending on how urgent the deadline is.
Avoid sending multiple reminders in the same week for the same ask. Clustering them back to back reads as pressure rather than a helpful nudge, and it can make the next follow-up feel harder to send.
Step 2: Write a subject line that gets opened
A good subject line tells the recipient exactly what's inside before they open the email. Front-load it with the specific action or date, since most inboxes truncate long subject lines and the first few words carry the most weight.
Vague subject lines like "Following up" or "Checking in" get skipped because they don't signal urgency or content. Compare that to something like "Invoice #204: payment due Friday" or "Contract for the Baker Studio project: signature needed." A freelancer chasing a signed contract might write "Quick signature needed on your design contract," while one nudging an overdue invoice could use "Reminder: invoice #118 is now 5 days past due." Both name the ask and the timeline in a single glance.
Step 3: Structure the body so the ask is impossible to miss
A reminder email should work even if the recipient only reads the first two lines. That means opening with context, stating the ask, and closing with a single next step, in that order, without burying any of the three under extra detail.
The opening line
Start with one sentence that places the email, not a full recap of the project or invoice history. Something like "Just following up on the invoice I sent on March 3rd" does the job. It orients the recipient without asking them to reread an old thread to remember what this is about.
The ask
State exactly what you need and by when, in plain language. "Could you send payment by Friday?" is clearer than "Let me know if you have any questions about the invoice," which doesn't actually ask for anything.
The close
End with one specific next step, not a list of options. A payment link, a proposed reply-by date, or a single question works better than offering several ways to respond, which can make the email feel like it needs more thought than it does.

Step 4: Match your tone to the type of reminder
The right tone depends on what you're reminding someone about. A payment nudge, a meeting reminder, and a second follow-up all call for a different balance of warmth and directness, even if the underlying structure from Step 3 stays the same.
Payment reminders
Keep payment reminders factual. Reference the invoice number and due date directly instead of leaning on guilt or apology, since a neutral tone reads as routine rather than confrontational. For more on getting this balance right, see how to remind someone to pay you politely and effectively.
Meeting or deadline reminders
These can be short and purely logistical. State the time, location or link, and any prep needed, and skip the pleasantries that slow down a message someone just needs to glance at before a call.
Follow-up after no response
Acknowledge the silence in one line, without assigning blame, then restate the original ask instead of re-sending the whole email. Something like "Wanted to bump this back to the top of your inbox" keeps it light while still moving the request forward.
Step 5: Set up automatic reminders for recurring tasks
An automatic reminder makes sense once a task repeats on a predictable schedule, like a monthly invoice due date or a recurring check-in with a retainer client. Instead of rewriting the same email each cycle, you set the rules once (when to send, how many times, and what the message says) and let the system handle it from there.
Most automation tools let you schedule a short series: one reminder a few days before the due date, another on the day itself, and a final one shortly after if payment hasn't come through. This mirrors the manual cadence from Step 1, just without the mental overhead of remembering to trigger it. Our guide to automated payment reminders: a complete guide for small business owners walks through setting up that kind of sequence in more detail.
The one risk with automation is sounding robotic. Keep your templates editable so you can adjust wording for a specific client or add a personal line when the situation calls for it, rather than letting every recipient get an identical, impersonal nudge.
Know when to send a follow-up (and when to stop)
A common cadence is one reminder before the deadline and one to two after, spaced a few days apart rather than sent back to back. That gives most clients enough room to respond without feeling chased at every turn.
Each follow-up should escalate gradually. The first stays light, the second gets more direct about the deadline, and the third can reference next steps if payment or a reply still hasn't come through, similar to the approach in how to write an overdue payment letter that gets results. If three reminders go unanswered, it's usually time to stop emailing and switch to a phone call, a formal notice, or another channel entirely.
How Bonsai helps with email reminders
Take a freelance web developer who invoices a retainer client for $1,800 each month. Writing a fresh reminder email each billing cycle is easy to forget when three other projects are due the same week, which is exactly the kind of recurring task an automatic reminder is built for. With Bonsai invoicing, you can set up automated payment reminders that go out before and after the due date on a schedule you choose once, so the invoice for that retainer client gets nudged without you drafting a new email each month.
Bonsai's automated invoice delivery works the same way for a bookkeeper who sends the same client an invoice on the first of each month: schedule it once and it goes out on time, with a confirmation email back to you so you know it landed. For a one-off reminder, like a designer following up on a $600 deposit invoice that's a few days overdue, you can still send it manually and adjust the wording so it doesn't read as generic. That flexibility matters, since Step 5 above notes that templates need room for a personal line every so often.
Bonsai's CRM, short for customer relationship management, keeps the context that makes reminders feel less robotic. Communication history and notes sit on each client's record, so before sending a second reminder to a client who missed a Zoom call, you can check the notes and reference the conversation instead of repeating yourself. Because Zoom meeting transcripts can sync to the client's record in Bonsai, a transcript from a kickoff call about payment terms is right there alongside the invoice history, giving you the detail to write a reminder that sounds like it came from someone who remembers the project, not a template.
FAQ
Q1: How do I politely send an email reminder?
A polite email reminder opens with a brief, neutral line of context, states the specific ask, and closes with one clear next step. Skip apologies or guilt-driven language like "sorry to bother you again," since a factual tone usually reads as more professional than an apologetic one. Naming the exact invoice number, deadline, or document keeps the message from feeling like pressure.
For example, a bookkeeper following up on a late payment might write, "Just checking in on invoice #204, due last Friday. Could you send payment by Wednesday?" That's direct without being terse, and it gives the recipient a concrete action instead of leaving them to guess what's needed. Politeness in a reminder comes from clarity, not from softening the ask until it disappears.
Q2: What's the right time to send an email reminder?
Send a reminder a few days before the deadline, while the recipient still has time to act, rather than waiting until after it's passed. For invoices, a common pattern is one reminder shortly before the due date and another a few days after if payment hasn't arrived. Meeting or document reminders often work fine with a shorter runway, sometimes just a day ahead.
Avoid sending more than one reminder in the same week for the same ask, since clustering messages can come across as pressure rather than a helpful nudge. Matching the reminder's timing to how urgent the task actually is, rather than sending on a fixed schedule regardless of stakes, tends to get better responses.
Q3: How do you write a professional reminder without sounding pushy?
A professional reminder without sounding pushy sticks to facts: the original request, the deadline, and one specific next step, instead of adding urgency words or repeated asks in the same message. Restating the request plainly, rather than re-sending the entire original email, also keeps the tone calm rather than insistent.
A freelance designer following up on a signature might write, "Wanted to bump this back to the top of your inbox. The contract is ready whenever you have a chance to sign." That acknowledges the delay without blaming the recipient and repeats the ask in a single sentence. Keeping each reminder short and specific, rather than layering on multiple questions or options, is usually what keeps it from reading as pushy.
Q4: Can I set up automatic reminders for recurring invoices?
Yes, an automatic reminder can be scheduled for recurring invoices so the same message goes out on a set cadence without being rewritten each billing cycle. Typical setups include one reminder a few days before the due date, one on the due date, and a final one shortly after if payment hasn't come through.
This works well for predictable, repeating tasks like a monthly retainer invoice, where the timing and wording rarely need to change. Keeping the template editable still matters, since an occasional personal line helps a recurring reminder avoid feeling generic to a client who receives it every month.
Q5: How does Bonsai help with email reminders?
Bonsai by Zoom supports automated payment reminders that go out before and after an invoice's due date on a schedule set once, which helps freelancers avoid rewriting the same reminder each billing cycle. Automated invoice delivery works similarly, sending recurring invoices on schedule with a confirmation email back to the sender.
Bonsai's CRM also keeps communication history and notes on each client's record, so a freelancer writing a second reminder can check past context instead of guessing what's already been said. Because Zoom meeting transcripts can sync to the client's record in Bonsai, details from an earlier call, like agreed payment terms, stay attached to that client's history and available when it's time to write a reminder that doesn't feel like a template.
Getting an email reminder right comes down to timing it before the deadline slips by, naming the ask clearly, and matching your tone to the situation, whether that's a payment nudge, a meeting confirmation, or a second follow-up after silence. For one-off messages, a little manual effort goes a long way; for anything recurring, an automatic reminder saves you from rewriting the same email each cycle. Bonsai's invoicing and CRM tools can help handle that recurring side of the work, so the reminders that matter most still get your personal attention.
