I'm posting to see if anyone else has seen this issue.
One customer has an email address that is used to receive emails from a 3rd party service that sends emails through sendgrid.
Last week the customer contacted us stating emails were no longer being received.
They have other email addresses that successfully receive emails from other services that use sendgrid.
If the customer provides a different email address using their domain to the 3rd party service, the emails are received.
Exim logs show other customers successfully receiving emails from the same 3rd party service via sendgrid.
But Exim logs show no emails arriving from the 3rd party service via sendgrid to the customer's email address.
From my perspective the issue is a 3rd party, or sendgrid issue.
Has anyone else seen this sort of behaviour from sendgrid?
I tried opening an old sendgrid account we had for testing purposes, but after confirming our business details we received an immediate notice stating: "After a thorough review, we regret to inform you that we are unable to proceed with activating your account at this time."
EDIT:
For a bit more context the 3rd party service doesn't include an unsubscribe link in the emails sent via sendgrid.
Issue is solved for the customer.
The 3rd party had blocked the customer's email address.
The frustration for the customer is that the 3rd party doesn't send bounce backs or failure messages.
So anyone trying to contact the customer using the 3rd party service thinks the message has been sent to our customer and that our customer is ignoring them.
