Setting Brevo SMTP on Supabase

[joaoguidev]

Hello.

Im trying to set Brevo transactional emails to be used by Supabase to send my confimation emails, magic link and so on instead of the built-in Supabase one but, without success.

Brevo gives me the following info to be used on SMTP:

From the image above, I'm setting Supabase on the studio like so

• (Brevo) SMTP Server --> (Supabase) Host ** this is: smtp-relay.brevo.com
• (Brevo) Port --> (Supabase) Port number
• (Brevo) Login--> (Supabase) Username *** this one is curious because in Brevo, the Login value is an email address
• (Brevo) I generate a SMTP key --> (Supabase) Password

In Brevo I registered my domain and also registered the sender with an email of the refered domain. I the mentioned email on the Supabase Studio SMTP fields "Sender email".

Has anyone had success implementing this? What am I missing?

Thank you.

I use my Brevo login email.

Hello GaryAustin1.

On the field password on Supabase, you create a SMTP key on Brevo and use it there right?

[GaryAustin1]

Yes.

It is strange. On the Supabase auth log I get "no such host" for smtp-relay.brevo.com.

[joaoguidev]

OMG!!!
There was a space before smtp-relay.brevo.com.
Forget it.

It worked.

it's not working for me there's no log for from supabase side when I try to send magic link it's getting sent sucessfully but on recipient's mail address it's not receiving

Shouldn't you check the log at Brevo? Whats the error message there?

[someshfengde]

I've tried to figure it out for like 2 hours then just shifted to resend. They have great integration with supabase setup took me just 1 minute.

You need to follow their SMTP instructions and fill in the fields as discussed above.
