How many times should you follow up on an email to a company you don’t know?

Follow up on a cold email once or twice, a few working days apart, and then stop. Each follow-up should add something useful, be shorter than the first email, and be easy to say no to. Stop at once when the person replies or asks you not to write again.

How many follow-ups is enough?

One or two. The first covers the ordinary case: your email arrived on a busy day and was set aside. The second gives the person one more clear chance to say yes or no. After that, silence is the answer, and a third or fourth message only changes how you’re remembered.

How long should you wait?

Wait a few working days before the first follow-up, and longer before the second. That gives the person time to deal with your first email if they meant to. A reminder the next morning reads as pressure.

What does a good follow-up do?

• It adds one new thing. A piece of work you did for a company like theirs, a detail about their situation you’ve since noticed, or the answer to the question they’d most likely ask.
• It’s shorter than the first. Two or three sentences. Your first email is still there underneath if they want it.
• It’s easy to say no to. Say plainly that a one-word reply is fine, and that you won’t write again if the answer is no.

What does a bad follow-up do?

• It leans on guilt. “I’ve written three times now” treats a stranger as someone who owes you an answer. They don’t.
• It “bumps” the first email. “Bumping this to the top of your inbox” adds nothing for the reader. It only says that you want something.
• It’s the fifth message. By then you are no longer reminding anyone. You’re hoping to wear them down, and it shows.

When do you stop?

• At any reply. A yes starts a conversation. A no gets a short thank-you and nothing more. “Not now” means ask when, and write once at that time.
• At any request to stop. Then it’s for good, from you and from anyone who sends for you. The rules on this are in Is cold email legal?.
• After the second follow-up. No answer to three emails is an answer.

An out-of-office isn’t a reply. Wait until the person is back before you start counting days.

Do the published reply rates include follow-ups?

Yes, and that’s worth knowing when you read them. Instantly’s 2026 benchmark gives an average reply rate of 3.43%. It counts every reply received, including replies to follow-ups, against all the emails sent. Hunter’s report on 31 million emails sent in 2025 gives 4.5%, counted per recipient across the whole series of emails they were sent, not per email. Both describe email sent with the company’s own software.

So the published rates already have follow-ups inside them. They don’t tell you how many replies a third or fourth message adds, and we don’t have a figure for that we’d put our name to. There is more on reading these numbers in our guide to cold email reply rates.

Questions people ask

Is two follow-up emails too many?

No. Two follow-ups, a few working days apart, is a reasonable limit as long as each one adds something and is easy to decline. A third or fourth is where it starts to read as pressure.

Should a follow-up be a reply to my first email or a new one?

A reply to your own first email. The person can then see what you’re referring to without searching for it, and your follow-up can stay short.

What do I do when someone asks me to stop?

Stop, permanently, and make sure anyone sending in your name stops too. If you answer at all, one line to confirm is enough. The rules that apply are in Is cold email legal?.
