MailerLite

MailerLite Classic API (Legacy)

The MailerLite Classic API serves legacy MailerLite Classic accounts. New integrations should target the current API at connect.mailerlite.com. Corrected 2026-08-13: the Classic documentation host is developers-classic.mailerlite.com (per the Classic API link in the current developer portal nav); the previously recorded classic.developers.mailerlite.com does not resolve.
