I am working on a “workflow” application that sends tasks to my Trello Inbox using SendGrid. The to: address is inbox@app.trello.com, and the from: address is the address associated with my account. I have verified that the email has been delivered via my SendGrid activity log. I have also verified that my Inbox is working by sending directly from my email client.
I have SendGrid configured with Sender Authentication using domain authentication so emails come from my domain rather than sendgrid.
I have also BCC’d the emails to another account and they are being delivered. Looking at the raw message, I confirm that the to: and from: addresses are correct and that my client (Gmail for Google Workspaces) passed the ARC tests (i.e. ensures source).
What else might be causing issues with getting emails send from SendGrid to show up in my inbox?
