Supabase Email Rate Limit Exceeded
Learn how to fix the Supabase email rate limit exceeded error by routing authentication emails through a third-party SMTP provider in 2 minutes.
Video Walkthrough
If you’ve been building with Supabase, you’ve likely encountered this error:
Email rate limit exceeded
This happens when Supabase’s built-in email service hits its rate limit for authentication emails (password resets, magic links, email confirmations). When this happens, users can’t sign up or recover their accounts.
Why You Need a Third-Party Email Provider
Something many developers don’t realize is how difficult it is to set up email infrastructure from scratch. Unless you’re sending millions of emails per month, you should use a dedicated email provider.
Routing your Supabase authentication emails through a third party solves two problems:
- Rate limits disappear - No more blocked authentication flows
- Professional domain - Emails come from your domain instead of Supabase’s
Prerequisites
- A Supabase project
- A Pingram.io account (free tier available)
Step 1: Set Up Your Email Provider
Sign up at Pingram.io. During onboarding, you’ll see a Supabase tab specifically for this use case. Select it and click Integrate with Supabase.
If you already have a Pingram account, navigate to Settings > SMTP and use the Integrate with Supabase button.
Step 2: Connect to Supabase
- Click the integration button and authorize Pingram
- Select your Supabase project from the dropdown
- Enter a sender name and address (e.g., “My App” and
no-reply@yourdomain.com)
Domain Verification
If you haven’t verified your domain yet, you’ll see a warning. The integration will still work, but emails will not come from your domain until you verify your domain in Pingram.
Bonus: Email Analytics and Logs
That’s it.
With your emails flowing through Pingram, you get visibility into:
- Delivery status - See if emails were delivered, bounced, or marked as spam
- Open and click tracking - Know if users are engaging with your emails
- Detailed logs - Debug delivery issues with full email previews
Access these from the Logs section in your Pingram dashboard.
