How many follow-ups should you send, and how far apart?

Many prospects do not answer the first message, so follow-ups are part of the method. That makes the number of them a decision and not a default. We have no anymail data to publish on the best count, so the numbers below are working conventions. Replace them with your own reply data after a few campaigns.

How many follow-ups should a sequence have?

Plan one first email and two to four follow-ups. Two is enough for a short, low-effort ask. Four suits an offer that needs more context. Beyond that, each extra step reaches fewer people who might still answer and more people who will mark you as spam.

The editor in anymail allows up to 25 steps in a campaign. Use far fewer. That limit is there for odd cases and does not suggest a target.

How far apart should follow-ups be?

Space them out as the sequence goes on. Short gaps early catch people who meant to answer, and longer gaps later stop you from becoming a daily nuisance.

New steps in the anymail editor start with a delay of 3 days, and you can change the delay on each step. Each step goes out inside a sending window you set, in the recipient's time zone.

What should each follow-up say?

Each one adds something the previous message did not. A reminder with no new content gives the recipient the same decision to make again.

1. Step 2. Add one new fact, such as a result or a short example. Keep it under 60 words.
2. Step 3. Change the angle. Ask about a different problem, or ask who owns this topic at their company.
3. Step 4. Say plainly that this is your last message. Make the ask easy to decline and leave the door open.

Keep follow-ups in the same thread. That shows the recipient the earlier message and makes the sequence read as one conversation.

When should a sequence stop for a recipient?

Stop on any of these.

• They reply, even with a refusal.
• They unsubscribe.
• Their address bounces.
• Someone else at the same company replies. (An out-of-office reply is not interest, so do not count it as a reply.) A reply from a colleague changes the situation, so keep the remaining steps from going out.

Branching helps here. A fixed sequence sends the same follow-up to everyone. A branching sequence sends different steps after a reply, a click, a bounce or silence.

What should you do after the last step?

Leave the person alone for a while. A prospect who has seen four messages and not replied has told you something. If the company is still a good fit, wait a few months and return with a new reason to write, such as a product change or a new role at their company. Treat that as a new first email with its own opening line, and do not restart the old sequence.

Check the list before you do. People change jobs and addresses go stale, so an address that worked in October may bounce in March.

What are the limits of these numbers?

The gaps and counts above come from common practice, and no single schedule suits every market. A buyer who takes a month to decide needs wider gaps than one who answers in a day. A short list of senior buyers needs fewer steps than a large list of operational roles. Read your own replies by step. If most replies arrive at step 2, step 4 may be unnecessary. If replies still arrive at step 4, a fifth step may earn its place.

How does anymail run follow-ups?

In anymail each step has its own subject, body and delay, and the sequence forks on a reply, a click, a bounce or silence. A reply from anyone at the company stops the steps that are left, and out-of-office replies are recognised and left out of the count. The details are on the sequences page.
