In their own words
PostBrix
PostBrix is a browser-based email builder for producing responsive templates and organizing assets for campaigns. Its visual editor lets users arrange text, images, buttons, dividers, and columns without writing HTML. Layouts are designed for mobile and desktop, and saved headers, footers, and calls to action can be reused across projects. The product can help generate or refine email copy with AI, then export templates as MJML or fully inlined HTML for an existing workflow. PostBrix says its exported code works with services that accept HTML or MJML, including Mailchimp, HubSpot, SendGrid, Brevo, Postmark, Amazon SES, Klaviyo, Customer.io, ActiveCampaign, and Mailgun. The documentation also describes REST API rendering and key management, live previews, test emails, responsive checks, and rendering troubleshooting. A free plan and free trial are available; paid plans start at $9/mo. The free tier is limited to five monthly exports, five daily downloads, three daily test emails, and ten lifetime AI generations.
