MailerLite email marketing — manage subscribers, groups, segments, campaigns, automations, forms, custom fields, and webhooks. Connect your own MailerLite API key to read and manage your own account's data here. Some features are plan-gated by MailerLite itself (e.g. resend/multivariate campaigns, advanced automation triggers) — this extension detects and reports that honestly rather than guessing.
