What action options does Valid Email Checker offer for Campaign Monitor? (Tag / Unsubscribe / Delete)

Once you pick a Campaign Monitor list and switch to Clean List Automatically in Valid Email Checker, the modal exposes three actions per result category. The dropdown labels are Keep, Unsubscribe, and Delete. The category rows (Invalid, Disposable, Catch-all, Unknown, Risky) match every other integration. The Campaign Monitor-specific behavior is what each action does inside your account.

How each action behaves

• Keep — VEC writes nothing back. The subscriber remains exactly as Campaign Monitor had them. Pick this when you want a results report without modifying production.
• Unsubscribe — VEC calls the Campaign Monitor API to set the subscriber state to Unsubscribed on the verified list. Custom fields, subscription source, and historical campaign engagement are kept. The subscriber stops receiving campaigns on that list but stays in the database.
• Delete — VEC removes the subscriber from the verified list. If the subscriber existed on only that list, Campaign Monitor treats it as a full account-level removal and the contact disappears.

Default settings

The defaults are the same as every other integration. Only the two unambiguously bad categories are enabled out of the box.

Override any default at any time using the Action dropdown next to each category. The Use Recommended Settings link in the modal snaps the panel back to defaults. Pair these settings with the list selection covered in how to select a list to verify.

What survives Unsubscribe

• Custom fields — every custom field on the subscriber stays attached.
• Signup source and date — preserved.
• Historical campaign engagement — opens, clicks, and other campaign data remain on the subscriber record.
• List membership — the subscriber stays on the list (just marked Unsubscribed) until you delete them explicitly.

Why the title says Tag and the UI says Keep

Tag/Unsubscribe/Delete is the industry shorthand for what a verification tool can do to subscribers after grading their addresses. Valid Email Checker uses Keep in the actual UI because that label honestly describes the no-op behavior — VEC writes nothing. Some other vendors tag every contact regardless of category; VEC leaves Campaign Monitor data alone unless you explicitly choose Unsubscribe or Delete.

Multi-client implications

Cleanups only affect the client whose list you verified. Subscribers shared across multiple clients in an agency account are not cross-touched — VEC scopes every write to the client and list you picked. This is important for agencies handling sensitive multi-tenant data.

The Risky category in practice

Risky bundles risky, spamtrap, and role_account from the engine. Spam traps in particular hammer Campaign Monitor deliverability — enabling Risky with Unsubscribe is the safe middle ground that protects your sender reputation without losing audit trail.
