Our account was disabled this week and it was like pulling teeth getting back into it. We were finally let back in and our account was enabled (yay!), so we scheduled a campaign because we had a large group of products launching last night.
However, this is what the campaign looks like currently and no one received the email.
Then, the email that our Klaviyo account has as the sender email, keeps getting emails from SendGrid saying “Invalid SMTPAPI Header”. We don’t know what this is and want help getting it resolved.

I want to apologize for the experience you are having pertaining to your account and the error you are receiving.
This behavior you are experiencing seems to be a latent behavior of your account being previously compromised.
After reviewing the interactions between yourself and our Compliance team, it appears our Compliance team was able to identify the issue and will follow-up with next steps. For further questions and clarifications, I would recommend reaching out and working directly with our Compliance team member assigned to your case via the open email thread.
Thanks for being a member of the Klaviyo Community! Have a wonderful day!
