Cannot get email to work

I'm totally new to this, although I have some limited DB/programming eperience.

I cannot get Akaunting to send emails. I am self-hosting (on Interserver), and I have tried my own emails on the same server and domain, as well as Gmail and nothing works.

I don't get any error messages just 'Invoice email has been sent', and there is nothing email related in the logs.

Is there an 'idiots' guide available anywhere?

I am on the verge of giving up on Akaunting, which is a shame, as it looks to be an otherwise excellent program.

I use resend for smtp.

1. Simply create an account on resend.
2. Add your domain. (example.com, not subdomain.example.com)
3. Go to resend settings, then to SMTP
4. Use those credentials under the email service settings in Akaunting.
5. Ensure the email in your company settings is set to something like [email protected] (The same domain you added in resend)
6. Create a test invoice to send to yourself.

If you run into any errors you can check the logs on resend and throw that into ChatGPT or your favorite LLM and it will guide you in case I missed something.
