Appwrite not using mail provider (mailgun) for sending OTP ?

I've added a Mail Provider (Mailgun) following the instructions here https://appwrite.io/docs/products/messaging/mailgun

I can send messages via mailgun using that. But I'm not in the email marketing game. All I want is for OTP emails to be sent via my custom domain using mailgun. I thought addding the email Provider would be enough but OTP are still arriving from:

Appwrite noreply@appwrite.io

Do I really have to set up a custom SMTP server (using Mailgun) ? This sort of makes the email Provider setup (above) redundant.

Thank you to anybody who can clarify.

It seems it falls under custom smtp.
The email provider setup is free for all if anyone building anything. And the customization of emails falls under pro.
As the free tier related stuff will sometimes contain branding.

Thanks @Axistro . Am actually on the Pro tier... just surprised that we have to set up a custom SMTP server as well as the Email Provider which we've already configured.

Thanks for confirming.

I dont think both are needed.
Only one is enough.
Although I forgot the details, long ago In one of my projects I enabled custom smtp and email provider at the same time, which caused some glitch I think and non of the mails were comming then I switched to only custom smtp which seems to have fixed the issue.
But it was long ago. Feel free to experiement.
