How long to wait before following up on an email

For most business emails, wait two to four working days before your first follow-up. Wait a little longer before each later one (about a week, then two). Follow up sooner when there is a real deadline, and later when the person told you when to expect an answer. Count working days, and skip holidays.

The reason for the gap is simple: you want to give the person enough time to answer on their own, but not so much that the thread has gone cold and they have forgotten what it was about.

The best follow-up date is often one the other person already gave you. "We decide after the board meeting on the 14th" means you write on the 15th.

Most replies come quickly or not at all. In an analysis of over 500,000 sales emails, Yesware found that 90% of emails that got a reply were answered within one day of being opened, and over half of those within 3 hours. So if a few days pass with nothing, the first email has probably been buried, and a follow-up is the only way it gets a second look.

Later touches still matter. Belkins analysed about 7.5 million B2B outreach emails sent over 12 months and found that the follow-up steps (steps 2 to 6) produced 58.6% of all replies. In other words, most replies in a sequence come after the first email, not from it.

Studies differ on the exact best gap, and most of them measure cold outreach rather than threads with people you already know. Treat any single "best number of days" with care; the ranges below are practical defaults that respect both sides.

Each row has ready-made emails in follow-up email templates. To turn a row into actual dates on a calendar, use the follow-up planner.

• There is a meeting, call or deadline in the next day or two that depends on the answer.
• You sent something they were actively waiting for (a contract, a quote they asked for that day).
• The person replies quickly as a rule, and this time they have not.
• You made a mistake in the first email (wrong attachment, wrong price): correct it straight away.

Usual reply time is a good signal. If a client always answers within a few hours and this time three days have passed, something is off, and a short check is helpful rather than pushy.

• They told you a date. Wait until the day after it.
• The decision involves several people (a buying committee, a board, an investment committee).
• It is a holiday period where they are. In Spain, August and Semana Santa are slow; across Europe, so are the weeks around Christmas.
• They are on leave: an out-of-office reply tells you exactly when to write again.
• The request is big for them (an intro to their network, a reference, a large purchase).

Time zones and working days

Count working days in the recipient’s calendar, not yours. A follow-up that lands at 07:00 their time sits at the top of the inbox when they start the day; one that lands at 23:00 is buried by morning.

For a single request to someone you know, two or three follow-ups after the first email is plenty. For planned outbound sales, a sequence of four to six touches over two to four weeks is common, and the Belkins data above suggests most replies arrive somewhere in that range. Planning one is covered in sales follow-up cadence.

Whatever the count, end on purpose. A last message that says you will stop ("I will assume this is not a priority and stop following up") is both polite and effective, because it asks for nothing hard.

Stop immediately when someone says no, asks you to stop, or unsubscribes.

Timing advice is useless if you forget the thread. A few ways to keep track, from manual to automatic:

• Write the follow-up date in your calendar when you send the first email.
• Use your mail app’s reminder or snooze feature on sent messages.
• Keep a "waiting for" label or folder and review it every morning.
• Let Skein watch the threads on your domain and draft the follow-up when one goes quiet for longer than that person usually takes.

Skein compares the silence with how fast each person usually replies, so a quiet day from a fast replier counts more than a quiet week from a slow one. By default it asks you before anything is sent. Try it on sample data in the demo.
