Before you choose
Pick an editor for the way you work
Compare editor type and custom code editing. A visual editor may suit a layout-focused workflow, while code editing matters if you need direct control over HTML.
Check whether the tool supports HTML export and reusable content blocks before choosing.
Check where you can work
The category includes web, API, self-hosted, browser extension, macOS, and Windows options. Confirm that a tool's platform matches how you plan to build or integrate email designs.
Compare plans and trial terms
A free plan and a free trial are different offers. Check what the maker lists for the plan, trial length, and paid starting price.
RGE Studio, formerly Beefree, offers a free plan and a 15-day trial; Blocks Edit's listing includes a free plan, a 30-day trial, and paid plans starting at $10 per user monthly.
Consider code access and licensing
If you need to read or change the code, compare custom code editing and HTML export. Check the maker's licence terms if open-source software is important to your choice.
Canary is listed as open source, and MJML is listed with a free plan.
