I sent out an email to the whole list from the Lead Database tab. And I don't see Email as a tab there... See screenshot.
Thanks!
Hi Chelsea,
To find out the Email deliverability rates, go to the smart campaign you used to send the email and then click the 'Email' tab. You will be able to see delivery % as well as soft & hard bounces.
When an email address returns a hard bounce, Marketo marks field 'Email Invalid' to "True" and stops attempting to send emails to that address.
Here's an articke that explains in more detail: https://community.marketo.com/MarketoArticle?id=kA050000000KzZyCAK
