Should I archive or delete contacts in Mailchimp?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
Archiving a contact in Mailchimp takes them out of your audience and off your bill, and keeps their record. Deleting removes them for good, record and all. Mailchimp is clear about which one to use.
Looking at 5,000 unsubscribes, it is tempting to think: they are gone anyway, why keep them? Here is why. The record of who opted out is the only thing that stops them being mailed again.
| Status | Paid or not paid | Note |
|---|---|---|
| Archived | Not paid | Data kept, including who unsubscribed. Importing them again unarchives them |
| Deleted | Not paid | Permanent. The status goes with the contact |
| Cleaned (hard bounces and repeated soft bounces) | Not paid | Already free. Mailchimp recommends archiving rather than deleting them, to avoid bounces |
| Reported spam (abuse complaints) | Not stated | Mailchimp moves them out of your active audience for you. Whether they still count is not on the pages we read |
Archive, in most cases. Mailchimp says to choose archive for outdated or inactive subscribers. Because the record stays, Mailchimp still knows who opted out, and someone who unsubscribed before you archived them can't be imported as subscribed.
Why not delete. A deleted contact takes its status with it. Unsubscribed, cleaned, all of it. Mailchimp won't let you import a deleted contact back into that audience. It says the only way back is the person rejoining through your hosted sign-up form, as someone new. But your old export still holds the address, and the day it goes into another tool, nothing is left to say they must stay off your list. The Almanac's suppression and deletion answer opens on exactly that scenario, and what happens when you delete a contact compares the tools. And deleting cleaned contacts saves nothing, because they are already free.
When to delete. When a person asks to be erased. Mailchimp says archiving is not a legal substitute for deletion then. Even so, keep a do-not-email record first. What you may keep to honour that person's opt-out is covered in the suppression and deletion answer, and unsubscribing is not the same as asking to be erased.
One catch after archiving. Re-imports unarchive. Check every import against your saved suppression files first.
