Email Invalid Error

[Anonymous]

I pushed out an email campaign this morning and noticed a particular lead had been blocked from mailings. When I went into the detail to find out why, it said it was b/c of an invalid email address. However, i checked over the email address and it is definitely correct. How do i resolve this? Any ideas?

It may have been caused by an email to that lead bouncing in the past (Marketo automatically marks leads with bounced emails as invalid). You can go to the lead page in the database and uncheck the "invalid email address" box manually to reverse this. Here is an idea I've implemented to prevent us from having that problem:
