What action options does Valid Email Checker offer for MailerLite? (Tag / Unsubscribe / Delete)
When you pick a MailerLite Group or Segment and switch the Valid Email Checker modal to Clean List Automatically, three actions become available per result category. The dropdown labels read Keep, Unsubscribe, and Delete. The category rows match every other integration (Invalid, Disposable, Catch-all, Unknown, Risky). What changes is how each action lands inside MailerLite.
How each action behaves
- Keep — VEC writes nothing back. The subscriber stays put. Custom fields, Group memberships, and historical engagement are untouched.
- Unsubscribe — VEC calls the MailerLite API to flip the subscriber status to Unsubscribed. Custom fields and engagement history are preserved. The subscriber stays in their Groups but stops receiving any future campaigns.
- Delete — VEC removes the subscriber from MailerLite entirely. Custom fields go with them. Other Groups the subscriber was a part of lose them as well.
Default settings
The defaults match every non-ConvertKit integration. Only Invalid and Disposable are enabled out of the box.
| Category | Enabled by default? | Default action |
|---|---|---|
| Invalid | Yes | Unsubscribe |
| Disposable | Yes | Delete |
| Catch-all | No | Keep |
| Unknown | No | Keep |
| Risky | No | Keep |
Click Use Recommended Settings to snap back to defaults. Pair these settings with the list selection in how to select a MailerLite list to verify.
What MailerLite preserves on Unsubscribe
- Custom fields — every MailerLite custom subscriber field stays attached.
- Group memberships — the subscriber stays in every Group they were in, just marked Unsubscribed.
- Signup source and date — preserved on the subscriber record.
- Historical campaign engagement — opens and clicks remain for reporting.
Why the title says Tag and the UI says Keep
Tag/Unsubscribe/Delete is the industry shorthand. Valid Email Checker uses Keep in the actual modal because that label honestly describes the no-op behavior — nothing gets written. Some other vendors silently tag every subscriber with their grades; VEC leaves MailerLite data alone unless you explicitly choose Unsubscribe or Delete on a category.
The Risky category in MailerLite
Risky bundles risky, spamtrap, and role_account. Spam traps damage MailerLite deliverability faster than any other category. Enabling Risky with Unsubscribe protects your sender reputation while keeping the audit trail and custom fields intact.
