Postcards
Postcards is a visual drag-and-drop builder for responsive marketing emails made from blocks and templates. Users can export clean HTML or send designs to listed email platforms, including Mailchimp, HubSpot, Klaviyo, SendGrid, Brevo, Constant Contact, and Zoho; export limits depend on the plan. Existing HTML emails can be imported and edited on paid plans. The AI Suite can generate templates from prompts and assist with editing, restyling, restructuring, translation, and design analysis. Shared workspaces, real-time collaboration, comments, and teammate roles support team work. Paid plans include Email Client Preview for checking Gmail, Outlook, Apple Mail, and Yahoo on mobile and desktop. The builder runs in a browser and requires an internet connection, though exported files can be opened and edited offline. Access is through the maker's hosted app link. The free Start plan costs nothing and includes 10 template projects, five monthly exports, 0 AI credits per month, 10 test emails daily, and unlimited teammates. Plus costs $16 a month; Pro costs $24 a month. The maker says user projects and content remain theirs and are not used to train AI models.
