Anyone else experiencing issues receiving sample emails today? We have been entering the necessary data in the send sample email box below as we always do but no samples have been received. We typically experience this when we are deploying a large email campaign but currently we are not deploying anything. Any ideas why this is occurring?
Check the white listing of Marketo IP addresses in your emailing system, although the fact that it's only today probably excludes this.
Also, try to send the sample from the Marketo main screen rather than from the email editor. I have observed that sometimes, the former works while the later don't.
