Edit your Supabase auth emails
without redeploying your app
Stable template UIDs let your backend keep calling welcome_v1 forever, while the content lives in a visual editor that anyone on the team can update. No more code changes for a typo, no more 2 emails/hour rate limits.
Why every Supabase founder hits this wall
Supabase Auth ships with default email templates. They work, technically — but the moment you want them to look like your product, you hit three problems no docs warn you about.
Hard rate limits
Free plan: 2 emails per hour. Pro plan: ~30. Launch on Reddit, blow past the cap, lose 90% of your signups silently.
Edits require deploys
Change a comma in the welcome subject? You're editing config in your Supabase project, redeploying, and praying the migration doesn't break your auth flow.
No designer access
Templates live in Supabase config or in raw HTML in your repo. Your designer/marketer/non-tech cofounder cannot touch them. Every change goes through engineering.
Stable template UIDs + visual editor
Your backend calls templates by ID. The content of each template lives in Minimo's drag-and-drop editor. Edit the content — the next send picks up the new version. No redeploys, no migrations, no engineering bottleneck.
Replace the Supabase SMTP
Point Supabase Auth's SMTP at Minimo. We become the transport layer. Two minutes, no code changes elsewhere.
Map auth events to template UIDs
Welcome → welcome_v1. Reset password → reset_v1. Magic link → magic_v1. Stable IDs your backend never has to know about again.
Edit templates without touching code
Open the visual editor. Change copy, design, branding. Save. The next email sent uses the new version. No deploy, no migration, no PR.
Built for the auth email use case
Stable template UIDs
auth_welcome_v1, reset_password_v1, magic_link_v1. The IDs your backend uses never change — only the content does.
Visual drag-and-drop editor
Designers and marketers update copy and layout without writing markup. Preview on real device sizes.
AI copy assistant
Generate friendly subject lines and body copy from a prompt. Ideal for non-native English founders or for brand voice consistency.
Zero code change
Your Supabase Auth code stays exactly the same. Minimo replaces the SMTP transport, not the auth logic.
Compliance maintained
DKIM/SPF/DMARC, opt-in tracking, GDPR-compliant storage in the EU. Same compliance as before, better deliverability.
No rate limits
Send 1,000 auth emails on Free, 10,000 on Starter, 50,000 on Growth. Forget the 2-per-hour Supabase wall forever.
