I have a transactional “Activate Your Account” email in a flow without a time delay, yet the email is in the waiting stage and will be there for a few hours.

I’m confident I don’t have any other rules in place to delay the send. I just sent a few copies of this email type without delay, yet a latest tranch of emails is delayed.

 

Why does this happen?

Hi @Andrew.Walters ,

Thanks for sharing.

Can you confirm the sender address in the emails and your account default sender emails match? Can you also look into the recipient activity of the flow? Does it shows that there has been recipients but the emails are being delayed and then bouncing due to the error code 550 5.7.26? This would means that the unauthenticated sending email from a sender email is not accepted due to domain's DMARC policy.

Thanks,

Alex

We had a timestamp issue, which is resolved.
