550rc from alert test with Sendgrid

  • What Grafana version and what operating system are you using?

8.1.5v via Helm chart

  • What are you trying to achieve?

I’m trying to set up a notification channel

  • How are you trying to achieve it?

By setting Sendgrid as SMTP server. We’re using API key as a method of authentication

  • What happened?

Sendgrid returns 550 code: Unauthenticated users are not allowed. When using the same credentials via Powershell Send-MailMessage (copy-pasted from grafana.ini) it works great. I’ve tried the same with base64 encoded password, Sendgrid Azure account and different TLS settings

  • What did you expect to happen?

I’ve expected that Grafana will be able to use Sendgrid as an email notification channel

  • Can you copy/paste the configuration(s) that you are having problems with?

enabled: true
host: smtp.sendgrid.net:587
from_address: grafana@notify
from_name: grafana
skip_verify: false
username: apikey
startTLS_policy: MandatoryStartTLS
password: xxxxxx

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.

UI: Failed to send alert notifications
Logs: 550: Unauthenticated users are not allowed

  • Did you follow any online instructions? If so, what is the URL?

Also smtp configuration, but cant link them as I’m a new user
