Supabase is a trademark of Supabase, Inc. emailsforsupabase.com is an independent tool and is not affiliated with, endorsed by, or sponsored by Supabase.
Supabase’s template editor takes basic HTML, but it leaves the hard parts to you:
This tool handles the branding and cross-client preview, so you paste tested HTML back into the dashboard instead of fighting the editor.
Welcome back
Why it’s different
Your colors, fonts, logo, and tone, pulled from your site and applied to every template. Not a generic email builder that doesn’t know Supabase.
Clean, inlined HTML tested across clients: bulletproof, well-maintained by team of experts.
The real GoTrue / Supabase merge tags are wired in. Export paste-ready HTML straight into your Supabase dashboard’s email templates.
These are the auth emails almost every Supabase app sends, branded and export-ready:
Plus the wider authentication & security set:
Branding is not sending. Supabase’s built-in email service is meant for development and is rate-limited. It is not for production. Branded templates still need custom SMTP to actually send, and your SPF, DKIM and DMARC records set up so they don’t land in spam. This tool fixes how your emails look; deliverability is a separate step.
How it works
Paste your site address. It scans every visible element: colors, fonts, logos, CTAs, and copy style.
Colors, typography, button shapes, logo, and your brand’s tone of voice, extracted automatically. No manual input needed.
Live preview with a dark-mode toggle, per-field edits, and one-click paste-ready HTML export for the Supabase dashboard. Merge tags are wired in automatically.
Supabase auth emails use template merge tags. The tool wires these in for you. Here they are verbatim, so you can check any export:
| Variable | What it holds |
|---|---|
{{ .ConfirmationURL }} | The full action link: confirm, recovery, invite, or magic link. |
{{ .Token }} | A 6-digit one-time code (OTP), as an alternative to the link. |
{{ .TokenHash }} | A hashed version of the token, for building your own custom action URLs. |
{{ .SiteURL }} | Your configured Site URL from the auth settings. |
{{ .RedirectTo }} | Where the user is sent after the action completes. |
{{ .Email }} / {{ .NewEmail }} | The current and new address, used in the change-email flow. |
{{ .Data }} | User metadata (user_metadata) for personalization. |
The security notifications add a few more: {{ .OldEmail }}, {{ .Phone }}, {{ .OldPhone }}, {{ .Provider }} and {{ .FactorType }}. See the Supabase email template docs.

FAQ
It’s a free tool that turns Supabase’s bare default auth emails into branded, production-ready templates. Paste your site URL, it reads your brand, and it generates every Supabase auth email with the real GoTrue merge tags wired in, ready to preview, tweak and export as paste-ready HTML for the dashboard.
Indie developers and side-project developers on Supabase who want on-brand auth emails without building an email system by hand.
Yes. During early access the tool is free: brand, preview and export every Supabase auth email template. A one-time $18 per-brand pack for saved brands and the full set is planned, but it isn’t live yet.
No. Branding changes how an email looks, not whether it’s delivered. Supabase’s built-in email is for development and is rate-limited; to send reliably in production you still need custom SMTP and your SPF, DKIM and DMARC records configured.
The core auth emails (Confirm signup, Reset password, Magic link and Change email) plus the wider authentication and security set: Reauthentication, Invite user, and the password / email / phone / identity / MFA change notifications.
