Email List Cleaning: A Step-by-Step Guide to Better Deliverability
Key takeaways
- Remove hard bounces right away.
- Send a ‘still want our emails?’ note to quiet contacts.
- Stop emailing people who do not reply.
- Use double opt-in to keep bad emails out.
A list full of old or wrong addresses can quietly damage your results, because inbox providers notice when many of your emails bounce or are ignored. Cleaning your list on a regular schedule keeps your sender reputation healthy and your costs under control.
Why should you clean your list?
- Bounces and spam reports hurt your sender name.
- Quiet contacts drag down your results.
- Brevo charges by emails sent, so dead emails cost money.
How do you clean a list, step by step?
- Remove hard bounces. Brevo blocks these by itself, and check them in your reports.
- Watch soft bounces. If one keeps bouncing, the address may be dead.
- Find quiet contacts. Make a segment of people with no opens or clicks in 90 to 180 days.
- Send a win-back email. Ask if they still want to hear from you.
- Stop emailing people who do not reply. Pause them instead of sending more.
- Fix clear typos, like “gmial.com”, if you know the right address.
- Turn on double opt-in on your forms.
How often should you clean your list?
| Task | How often |
|---|---|
| Check bounces | After every campaign |
| Review quiet contacts | Every 3 months |
What is one more helpful tip?
Cleaning your list may feel like losing subscribers, but the people you remove were not reading your emails anyway. A smaller, active list usually brings more clicks, fewer spam complaints and lower costs on volume-based plans like Brevo’s.
What does this look like in practice?
For example, a music school with 3,000 contacts might find 400 people who have not opened anything in six months. After one friendly win-back email, it could keep the 60 who reply and pause the rest.
Questions people ask
Should I delete quiet subscribers?
Pausing or removing people who ignore a win-back email usually helps. Keep any records your privacy rules require.
