What EmailJS is

EmailJS lets front-end code trigger transactional email through connected providers—handy when you only need ‘send this payload to Gmail.’

It does not replace a submission database; searching old leads means searching email threads.

How MuxForms differs

MuxForms stores every submission, validates against schema, and can still email your team.

Pick EmailJS when email is the only persistence you want; pick MuxForms when support needs a searchable inbox and apps POST JSON.

Pricing and limits (honest)

EmailJS quotas count sends, not stored rows—cheap until marketing traffic spikes.

MuxForms pricing is tied to form ingestion and dashboard access, not per-email API call.

When MuxForms wins

  • You need history, exports, and the same backend for web + mobile.
  • You want server-side validation and honeypot without exposing email credentials to the client.

When EmailJS wins

  • Tiny static site, email-only, and you accept client-side send limits.
  • You already wired EmailJS templates across a portfolio.

Common questions

Is MuxForms a drop-in replacement for EmailJS?
For many contact and lead forms yes—match field names, update the endpoint or embed, and allow your site origin. Complex workflows may need a feature checklist.
What about CORS errors?
Browser embeds and client fetch require your production URL on the form allowlist. Server Actions and mobile JSON with the ingest secret do not use CORS.
What does HTTP 403 mean?
Disallowed origin, missing ingest secret, invalid submit token, paused form, or failed Turnstile. Read the JSON error message in the response.
What does HTTP 422 mean?
Validation failed—field names and lengths must match the schema defined in the MuxForms dashboard.
When is EmailJS still the better tool?
See the “When EmailJS wins” list on this page—we try to be honest when EmailJS fits your workflow better.
How does pricing compare?
MuxForms is $9/month for unlimited forms on the paid plan. Use the comparison table above for EmailJS's caps.

Try the backend, not another form brand.
