MJML.ai Use Case
MJML Repair tool for broken email code
Paste damaged MJML or raw HTML and get back cleaner, valid MJML plus compiled output. This is the fastest path when a legacy template breaks, imports poorly, or fails validation.
Fix invalid structure
Resolve malformed sections, unsupported nesting, and syntax mistakes that cause rendering failures.
Convert chaos into maintainable MJML
Turn hard-to-edit legacy snippets into readable MJML teams can update safely over time.
See what changed
Review before/after validation and rationale so fixes are auditable instead of opaque.
Best-fit scenarios
- A campaign fails because old markup no longer compiles cleanly.
- You migrated from another builder and the resulting HTML is difficult to reuse.
- You need quick recovery of a template without rewriting from scratch.
Keep moving after repair
After fixing structure, validate and optimize the final version for ongoing production use.
