How to write a client follow-up email that gets a reply
Short, specific and easy to answer, with templates for the three moments clients go quiet.
On this page
A follow-up email gets a reply when it is short, names one decision and is easy to answer in a line. Skip the apology and the "just checking in." Give the client a yes or no, or two dates to pick from. Silence usually means the email slipped down the inbox, not that the answer is no.
Why clients go quiet
Silence is almost never a verdict on you. The email landed in the middle of a meeting. It needed a sign-off from someone on holiday. The client meant to reply, forgot, then felt a little guilty, which made replying harder.
The data backs up the case for trying again. In Instantly's analysis of its own users, the first email captured 58% of replies and follow-ups produced the other 42%. Belkins' 2025 study puts follow-up steps at 58.6% of replies. The two datasets count differently, but they agree on the point: a large share of your answers sit behind the second and third message. These are cold outreach numbers, so expect warm clients who already asked for your proposal to reply even more often.
Treat a quiet client as a logistics problem. A follow-up is you doing the small admin job the client wishes they had time to do.
The four parts of a good follow-up
Get these four right and the template nearly writes itself.
The subject line
Keep it short, plain and specific. Backlinko's study of 12 million outreach emails found that subject lines of 36 to 50 characters got the best response, which is roughly five to eight words. "Quick question on the homepage copy" beats "Following up :)". Reply in the same thread when you can, so the client sees "Re:" and recognises the conversation.
Avoid the classics: "just checking in," "circling back," "per my last email." They tell the client they are late, and people who feel accused reply slowly.
The opening line
Lead with the one thing you need. Compare two openings.
- Weak: "Sorry to bother you again, I know you're super busy, just wanted to see if you'd had a chance to look at the proposal I sent last week."
- Strong: "Quick one: are we good to start the homepage on Monday, or would you rather push to the following week?"
The strong version can be answered in three words. The weak one asks the client to reconstruct the context, manage your feelings and write a paragraph.
The ask
Offer a small menu, not an open field. "Does Tuesday or Thursday work better for a 20 minute call?" is easier than "Let me know when you're free." A yes or no question, or two dated options, removes the need to think. You are not asking the client to plan. You are asking them to pick.
The close
End with a reason to act now that is true. "I'm holding a slot for you next week and can confirm it once you give the word" works. If your availability is limited, say so plainly. Real scarcity persuades. Invented scarcity gets noticed and resented.
When to send and how often
Quality matters more than timing, but timing still moves the number.
On the weekday question, Belkins' reply rate data shows Wednesday and Thursday tied as the best days at 0.48% each. Do not obsess over it. Landing in the inbox before the client's day fills up matters more than a magic minute.
On spacing, a simple rhythm fits most service work:
- Day 0: the original email, whether it is a proposal, a deliverable or a request.
- Day 3: the first follow-up. This one recovers most of the replies you would otherwise lose.
- Day 7 to 10: the second follow-up, with a new angle or a small piece of value.
- Day 14 to 21: a polite close-out.
Then stop. Belkins recommends three to five steps for most sequences and notes that after step five, volume falls sharply and returns shrink fast. Three well-built follow-ups beat eight desperate ones. After the close-out, let it rest and reach out again in a month with something new.
Three templates for the moments clients go quiet
Swap the brackets for real details. Personalisation counts: Backlinko found that personalised message bodies got 32.7% more replies than generic ones, so spend ten seconds mentioning the actual project.
1. The proposal that went silent
Subject: Re: [Project] proposal
Hi [Name],
>
Following up on the proposal I sent on [date] for [specific deliverable]. I currently have space to start the week of [date].
>
Two quick questions so I can hold that slot: does the scope match what you had in mind, and is the [price] within the budget you're working with? Happy to adjust either.
>
If now isn't the right time, tell me and I'll check back next quarter.
>
[Your name]
This names the decision, offers to flex on the two things clients hesitate over (scope and price) and gives a graceful exit. The exit does the work. Permission to say "not now" often produces "yes, let's go."
2. The client who disappeared mid-project
Subject: [Project]: need your call on [the blocker]
Hi [Name],
>
The [deliverable] is ready and waiting on your review before I can move to [next step]. It's the one thing holding up the [date] delivery.
>
Could you take a look by [day]? If it's easier, I can walk you through it on a 15 minute call. Tuesday or Wednesday afternoon both work.
>
[Your name]
The message frames the silence as a risk to the client's timeline, not to your feelings. That reframe moves stalled approvals. If chasing approvals has become a regular tax on your week, read our guide on how to stop scope creep, because vague approvals and creeping scope tend to arrive together.
3. The invoice stuck in limbo
Subject: Re: Invoice [#] for [Project]
Hi [Name],
>
I wanted to make sure invoice [#] for [amount] didn't get buried. It was due [date], and I'd like to confirm it's with the right person on your side.
>
If it's already in the payment queue, ignore me. If it needs anything from me (a PO number, a different format, a contact in accounts), tell me and I'll turn it around today.
>
[Your name]
The first nudge should assume good faith. If the client keeps stalling, our guide to handling late-paying clients covers the firmer steps. In the UK, for instance, the government says business-to-business debts can carry statutory interest of 8% plus the Bank of England base rate unless your contract sets another rate. Whether that applies to you depends on where you and the client are, so check it with your accountant or lawyer.
Three checks before you hit send
Read your follow-up back and run these.
First, the one-line test. Can the client answer in a single sentence, or even one word? If they have to scroll up, find a file or write a paragraph, cut the ask down.
Second, the tone test. Read it aloud. If it sounds anxious, apologetic or faintly accusing, rewrite it flat and calm. Inboxes are crowded, and Belkins found an average reply rate of only 0.45% across its 2025 campaigns, so patience is thin. Calm reads as competence. Worry reads as a red flag.
Third, the value test. Does the message give the client a reason to open it beyond your need? A good second follow-up carries something new: a mockup, a relevant article, a heads-up about your calendar. You are reminding them why working with you is the easy choice.
Stop being the status bar
The best follow-up is the one you never write, because the client could already see the answer.
A lot of chasing exists only because the client cannot check status on their own. Where is the file? Did I approve this? Has the invoice gone out? Each question becomes an email you send and a reply you wait for. Moving work out of the inbox is the single biggest cut to your follow-up load. If your client work is scattered across chat apps, our post on why you should stop running your business on WhatsApp explains the cost.
How Delivvo cuts the number of follow-ups you send
Delivvo puts the quote, the approval and the invoice where the client can see them, so fewer things go quiet in the first place.
- A new inquiry arrives through your inquiry form and lands on your lead board. An automation can send the first reply on its own, with your price list and booking link, so the client hears from you in minutes.
- You send a quote built from your packages and add-ons. The client picks, signs the contract and pays the deposit from one link, so there is no separate "did you sign it?" email.
- Work moves through the client portal, which opens with a one-time code and no password. Approvals are a click in the portal, and the client can see what is waiting on them.
- Invoices carry a payment link that works through your own gateway. If one goes unpaid, an automation sends reminders at 7, 14 and 30 days and stops once it is paid.
- Every invoice and contract has a verification code, so nobody has to ask you to confirm a document is real.
You still write the human follow-ups, like the proposal nudge above, and that is the right split. A personal note to a hesitant client should come from you. The routine reminders about a late payment or a missing reply to your first message are exactly the kind of thing a rule should send, so you do not have to remember them at the end of a long week. Clients pay you directly, and Delivvo takes 0% of the payment. See how the pieces connect on the automations page.

FAQ
How many times should you follow up before giving up?
Three to four touches over two to three weeks, then stop and try again next month. Belkins recommends three to five steps and says returns fall sharply after step five. Spacing them out keeps each one reading like a reminder, not nagging.
What is the best subject line for a follow-up email?
A short, plain one of 36 to 50 characters that names the project or the decision, according to Backlinko's outreach study. Replying inside the existing thread beats a new subject line, because the client already recognises it. Skip "just checking in."
Should I follow up by email or another channel?
Start with email so there is a written record. Move to another channel only if your relationship with the client already runs there. A personal message app for a business approval can feel invasive and leaves no clean trail.
How long should I wait before following up on a proposal?
About three days for the first follow-up. A proposal is a decision, so give the client a short window to read it, then ask one clear question. Wait longer between the next two, and close the loop politely if there is still no answer.
