Our verdict on Kettlemail
Kettlemail is a browser-based email template builder for people who create designs for use in external campaign platforms or sending services. Its drag-and-drop editor offers sections, columns, text, buttons, images and other email elements, while a synchronized MJML editor and raw HTML blocks give users code-level control. The product is described as free and open source, and its browser-based workflow suits solo users and small teams who want to prepare templates without adopting a campaign-sending platform.
The main draw is the range of design and checking tools in one builder. Users can preview client-specific rendering, run a compatibility linter and watch a live Gmail message-size meter. AI tools can draft emails, revise individual blocks, and generate subject lines and preview text. Test sends go to the user's inbox. Once a design is ready, Kettlemail can export self-contained HTML with inlined CSS, MJML or re-importable JSON. This mix makes it useful for both visual-first editing and workflows that need editable markup or a portable template file.
Kettlemail is designed to hand work off to other services, not to manage or send campaigns itself. Its listed integrations include Mailchimp, Brevo, Klaviyo, HubSpot, Constant Contact, GetResponse, ActiveCampaign, MailerLite, Resend, SendGrid, Amazon SES, Mailgun, Postmark and SMTP.com. Templates are stored in the user's browser, so the product is a better fit for template creation than for centralized campaign operations. Documentation is the stated support channel. Choose it if free, open-source template editing with MJML and compatibility checks is the priority; choose a campaign platform instead if sending and managing campaigns in the same product is essential.
