MailerLite Connector Extension

Whether the user's own MailerLite API key is connected. Use for: is my MailerLite account connected, connection status.

Connect a MailerLite account by saving its API key. Validates the key against MailerLite before saving. Use for: connect my MailerLite account, save this API key.

List every MailerLite account you've connected - label, masked key, which one is active.

Switch which connected MailerLite account is active - all following calls use this one.

Disconnect ONE specific connected MailerLite account by its label - removes only that key.

List subscribers, optionally filtered by status (active/unsubscribed/unconfirmed/bounced/junk). Use for: list my subscribers, show active subscribers.

Create or update (upsert) a subscriber by email. Non-destructive - omitted fields/groups are NOT removed from an existing subscriber. Use for: add this email to my list.

Fetch one subscriber by id. Use for: get subscriber details.

A subscriber's engagement activity (opens, clicks, etc). Use for: subscriber engagement history.

Assign an existing subscriber to a group.

Remove a subscriber from a group.

Permanently delete a subscriber.

GDPR 'right to be forgotten': permanently erases this subscriber's personal data (distinct from delete_subscriber, which just removes the record - forget is MailerLite's own compliance endpoint, POST /subscribers/{id}/forget, confirmed via MailerLite's official SDK source). Use for: forget this subscriber, right to be forgotten.

List mailing groups. Use for: list my groups.

Create a new mailing group. Use for: new group called X.

Rename an existing mailing group.

Permanently delete a group (subscribers stay, just un-grouped).

List subscribers belonging to a group.

List dynamic subscriber segments. NOTE: segment filter rules are built in the MailerLite UI only - this extension can list/rename/delete existing segments but not author new filter logic. Use for: list my segments.

Rename a segment (filter rules themselves can't be edited via API).

Permanently delete a segment.

List subscribers matching a segment's rules.

List campaigns filtered by status (sent/draft/ready) and/or type (regular/ab/resend/rss). Use for: list my campaigns, show draft/sent campaigns.

Fetch one campaign by id. Use for: get this campaign.

Create a draft campaign. type='resend'/'multivariate' and content_html both carry a REAL risk of being rejected on lower MailerLite plans - any such rejection is surfaced with MailerLite's own exact wording, never guessed. Use for: draft a new campaign called X.

Schedule a ready campaign to send (or send it instantly with delivery='instant'). Use for: schedule this campaign for tomorrow, send now.

Cancel a campaign that's currently in 'ready' state (queued to send). Use for: cancel this send.

Permanently delete a campaign. Use for: delete this campaign.

List automations (name, enabled/disabled, created date) - read-only. MailerLite's API can't build or edit automation steps; those are UI-only. Use for: list my automations, show automation workflows.

Fetch one automation's basic info by id. Use for: get this automation.

Subscriber activity flowing through an automation, filtered by status (completed/active/canceled/failed - required). Use for: who's in this automation, automation subscriber activity.

Create an EMPTY draft automation (name only) - MailerLite's API can't define triggers/steps, so the user still needs to open MailerLite's UI to actually build the workflow. Use for: create a draft automation shell.

Permanently delete an automation. Use for: delete this automation.

List forms of one type: popup, embedded, or promotion (required - MailerLite has no combined 'all forms' endpoint). Use for: list my popup/embedded forms.

Rename a form. Use for: rename this form.

Permanently delete a form. Use for: delete this form.

Create a webhook for a MailerLite event (e.g. subscriber.created, campaign.sent - see MailerLite docs for the full event list). campaign.click/campaign.open/subscriber.deleted REQUIRE batchable=true (MailerLite's own requirement). Use for: add a webhook for this event.

Permanently delete a webhook. Use for: delete this webhook.

List valid language_id values for campaign unsubscribe-page language.

List valid timezone_id values for scheduling campaigns.

Show this MailerLite account's REAL plan (name, price, subscriber tier, smart-sending flag - read directly from MailerLite's own account endpoint) plus any capability restrictions actually observed from live API responses, and MailerLite's own documented plan gates for things the account endpoint doesn't itself describe (e.g. whether HTML campaign content is unlocked at this tier). Use for: what MailerLite features am I limited to, plan limits.
