Auth emails delayed (5–10 mins) using Supabase built-in email service
authHi,
I’m using Supabase Auth with the built-in email provider for sign-up confirmation and password reset emails.
I’m consistently seeing significant delivery delays — emails arrive after 5–10 minutes, sometimes even longer.
Details:
• Supabase project region: US East (Ohio)
• Users located in: India
• Issue happens for both sign-up and reset password flows
• Emails do eventually arrive (no auth errors)
I wanted to clarify:
Are such delays expected behavior with the default/shared email service?
Is this due to queueing, IP reputation, or regional factors?
Is using a custom SMTP (Resend / SES / Postmark) the recommended solution for production apps?
Are there any plans to improve real-time delivery for the built-in provider?
I’m trying to decide whether to immediately switch to a custom SMTP or if there are best practices to improve delivery with the default setup.
Thanks in advance
