PostBrix vs Stripo

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.

Stripo is an email template builder available on the web and through an API. Its drag-and-drop and HTML editors support interactive content, modular email structures, reusable blocks, custom code, custom fonts, and HTML export. The service includes more than 1,650 customizable HTML templates. Finished emails can be pushed to more than 90 email service providers, exported to Gmail or Outlook, sent to CRMs through Zapier or Webhook, or downloaded as PDF, images, or HTML. Email on Acid integration supports testing across 98 mobile, desktop, and web clients. Teams can assign roles, share previews, and co-edit in real time. The Free plan lasts without a fixed term while the account remains active, but excludes ESP export, colleague collaboration, client rendering previews, and tests to other addresses. It includes two members, four monthly exports, five daily test emails, and ten stored emails. Paid plans start at $20 a month.
