How to Connect
In RocketVerifier open Dashboard → Integrations → MailerLite, paste the credentials below (a token for the new MailerLite API) and click Connect. They are validated against the platform before anything is saved.
Pick the source to sync, the schedule and the write-back options in the integration settings, then click Sync now or wait for the schedule.
| Field | Required | Where to find it |

| API key | Required | MailerLite → Integrations → API (new MailerLite, connect.mailerlite.com). |
Credentials are stored encrypted and are only ever sent to the platform's own API hosts.
What It Syncs
Sources
All subscribers or any group.
Incremental syncs
Subscribers whose updated_at is after the last sync (filtered by RocketVerifier; MailerLite has no server-side filter).
Schedules & Credits
- Schedule: Manual only, Daily, Weekly or Monthly. Each run syncs the source chosen in the settings; Sync now starts one immediately. Only one sync runs per integration at a time.
- Mode: Full re-checks every contact in the source except those verified in the last N days (default 30, 0-365); Incremental only checks contacts changed since the last sync.
- Each sync creates a regular verification job: 1 credit per unique address, and
unknownresults are refunded when it completes. If the balance is too low the sync stops withinsufficient_creditsbefore anything is charged. - Results are written back when the job completes; the sync history in the dashboard shows updated, failed and skipped counts per run.
Write-back
Fields ("Write status fields")
rv_email_statusrv_email_sub_statusrv_email_scorerv_verified_at
Custom fields (labels RV Email Status etc.), created on first use.
Status values are deliverable, undeliverable, risky and unknown (disposable addresses are undeliverable, catch-all addresses unknown). Sub-status is a sub_status value (none when there is no extra detail), score is 0-100 and verified-at is an ISO 8601 UTC timestamp.
Action Rules
In the integration settings, pick an action per result: Invalid, Disposable, Risky, Catch-all, Unknown or Valid. Actions run after the field/tag write-back.
Unsubscribe
Sets the subscriber to unsubscribed.
Move to list
Adds the subscriber to the group you pick.
Beta: the MailerLite connector is new. Sync reports list every contact that could not be updated; please tell us if something looks wrong.
