email otp limit
Hi all, I am new with superbase. According to image
1) means if I use that endpoint my application can send 2 email / hour using default SMTP
2) what about otp using end point /auth/v1/otp how many per / hour using default SMTP ?
And what is best practice default SMTP vs custom SMTP
I know about 50K MAU limit on free tier what about EMAIL and OTP limit ?
My use case for now I am using email + opt based authentication. I think I need to send email for purchase of pro plan that it

If you are using the default SMTP it’s 2 emails per hour. You should only use the default SMTP for light testing otherwise you should use a email service and add their custom SMTP settings into the Supabase dashboard. The default SMTP rate limit doesn’t change even on pro plans. You just need your own SMTP provider and it will allow you more emails per hour on any plan you are on (yes including free plan).
But I tried with default SMTP I am able to send 7-8 otp to different emails using end point /auth/v1/otp . So how, Is there something I am not aware of
Pro or Free does not impact this. You need your own SMTP even for serious auth debugging (IMO) but certainly for an app with users.
