Emails reported not delivered, but were

[SStoddard]

We sent out an email over the weekend.  For each recipient, Hubspot reports "There was an issue sending an email to this contact. This email wasn’t sent."

However, it was.  Some of the users have opened the email.  Anybody know what's going on?

Never mind!  The issue seems to have resolved itself.
