We have a customer who is disputing whether an email was actually sent to them. We sent this email using File drop automation from Marketing cloud
I can see in the tracking that the email got delivered and was also opened. The email address is also correct.
Sorry for the strange question, but is there any more evidence that can be provided here. Are there email logs saved in .zip format in Marketing Cloud. Also to future proof this, can we have a .pdf email 'sent either via FD automation or a Journey' saved maybe in our data warehouse when they are sent?
