Common questions
What to know before the first upload.
Why use MJML for generated email?
MJML gives teams a safer high-level structure for responsive email than hand-editing raw table HTML.
Can I edit raw MJML?
Mailmedium uses structured controls for common refinements. Paid export also includes template.mjml for teams that want to continue in code.
Does the exported HTML contain private app links?
No. Export validation rejects unresolved private app links and rewrites approved assets to relative paths.
