Free is forever and includes 5 credits per month, 1 brand profile, 250 MB of media storage, the visual block editor and MJML and HTML export. Starter is $15 per month with 25 credits, 5 GB of storage, unlimited brand profiles and the knowledge base. Pro is $39 per month with 75 credits and 20 GB of storage.
The Free plan doubles as the trial, and the knowledge base is not available on it. Prices checked on 2026-09-29.
