Hello @DakshMiglani,

How did you solve your issue?

Yea, so I was running my emailing service on kubernetes which was also supplying it the sendgrid key via secrets, But I didn't realise that it was also adding a '\n' character to it.

That's why later, when I checked the sendgrid api key, it looked like:
"SG_SOME-KEY-HERE\n".

So I stripped that newline character and boom it started working.
