Maizzle vs Postcards

Maizzle is a free, open-source framework for building HTML emails with Vue and Tailwind CSS. It works in standalone projects, monorepos and existing applications through a Vite plugin. The development server offers live preview, hot module replacement, device resizing, compatibility checks, dark-mode emulation, search and test-email sending. Tailwind configuration is adapted for email, including Outlook utilities and variants for clients such as Gmail and iOS. The framework provides render-tested components including Container, Row, Column, Button, Img, Heading and CodeBlock, with documentation describing more than 30 components. Configurable transformers can inline CSS, remove unused styles, minify output and apply other email optimizations. The CLI scaffolds projects, runs the server, builds templates to HTML and generates plaintext versions. An API exposes render(), build() and serve(). Documentation covers Vite integrations and deployment services including Nodemailer, SendGrid, Mailgun, Postmark, Resend, AWS SES and Cloudflare. Output is pure HTML usable with any email service provider. Platforms listed are API, self-hosted and web.

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.
