Wait two to three business days before your first follow-up, then a little longer before each one after that. If they emailed you first and went quiet, follow up sooner, after about two days. If it’s someone new you pitched, give it three to five days. After a meeting, send your recap the same day or the next. The exact number matters less than actually sending it, so the simplest fix is to pick the wait once and let a tool send the follow-up for you. In Mixmax, you write the follow-up, set the days, and it sends only if they haven’t replied.
These are practical defaults, not rules. Here’s how to pick the right wait for each situation.
How long should you wait before following up on an email?
Start from one question: who started the conversation?
If they reached out to you, they already want something. Silence usually means they got busy, not that they lost interest. A short wait is fine and often welcome.
If you reached out to them, they owe you nothing. Give them more room, and space each follow-up out a little more than the last.
A default wait for each situation
| Situation | First follow-up | After that |
|---|---|---|
| They emailed you first, you replied, then nothing | 2 business days | 3–4 days, then a week |
| A pitch to someone who doesn’t know you | 3–5 business days | About a week each time |
| After a meeting or call | Same day or next morning (the recap) | 3–4 days if they owe you an answer |
| After you sent a proposal or quote | 2–3 business days | About a week |
| A client or contact who’s always slow | Match their pace, often a week | 1–2 weeks |
| They said “let’s talk next month” | The week they named | A week later |
A few things change the numbers.
- They gave you a date. If they said “after the 15th,” follow up on the 16th, not before. Keeping their date shows you listened.
- There’s a real deadline. If an offer ends Friday, it’s fine to follow up sooner and say why.
- Weekends and time zones. Count business days, and send when they’re likely at their desk. Gmail’s schedule send lets you pick the exact time. (Gmail Help: Schedule emails to send)
Why the wait matters less than you think
Most follow-ups don’t fail because they were sent on day three instead of day four. They fail because they were never sent. You meant to, the week got busy, and by the time you remembered it felt too late.
That’s why the most useful thing you can do is decide the wait once, when you send the first email, while the conversation is fresh. Then the follow-up isn’t a task you have to remember.
How to set the wait once and let it send itself
Here’s how in Mixmax, a lightweight outreach tool inside Gmail.
For a single email
- Write your email in Gmail.
- In the Mixmax bar at the bottom of the compose window, add a reminder for if they don’t reply, and choose the day.
- Send. If they reply first, the reminder never bothers you. If they don’t, you get it on the day you picked.
For emails you send again and again
- Create a sequence: your first email plus one to three follow-ups.
- For each follow-up, set the wait in days, using the table above as a starting point.
- Add people. Type them in, bring them from a CSV, Salesforce or HubSpot, or add someone straight from your reply.
- Start it. Each follow-up sends as a reply in the same thread, from your Gmail address, on the day you set.
- When someone replies, their follow-ups stop.
Best for: anyone who sends the same kind of email over and over and keeps losing track of who they still need to chase. Think founders writing to investors, recruiters reaching out to candidates, agents answering new enquiries, or consultants checking in with past clients.
What to write when the day comes
Keep it short and easy to answer. A good follow-up does one thing: makes replying take ten seconds.
Hi Sam, bumping this up in case it got buried. Would Tuesday or Wednesday work for a quick call?
Hi Priya, just checking you saw the quote I sent Monday. Happy to adjust anything. Want me to hold the start date?

Frequently asked questions
How many days should you wait to follow up on an email?
Two to three business days is a good default for most emails. Go shorter (about two days) if they emailed you first, and longer (three to five days) for someone who doesn’t know you yet.
Is it rude to follow up after 24 hours?
Usually, yes, unless there’s a real deadline or they asked you to. The one exception is a meeting recap, which is best sent the same day or the next morning.
How long should you wait between follow-ups?
Space them out more each time: a few days before the first, about a week before the second, then a week or two. See how many times to follow up for when to stop.
What if they replied but didn’t answer my question?
That’s still a reply, so your automatic follow-ups should stop. Answer them by hand. In Mixmax, any reply stops the sequence for that person.
Can I schedule a follow-up email in Gmail?
You can schedule any email with Gmail’s schedule send, but it will still go out if they already replied. A follow-up tool like Mixmax only sends if they haven’t.
Does Gmail tell me when to follow up?
Gmail’s “nudges” can bring a sent email back to the top of your inbox, but Gmail decides which ones and when. More in does Gmail have automatic follow-up?
The next step
Open your sent folder and find the last email you’re still waiting on. Decide the wait now, write the follow-up now, and let it send if they don’t answer. Start free with your Google account, no credit card.
