I sent a test version of a promo email to myself so I could check all of the links, make sure the images loaded properly, etc. I managed to accidentally mark it as spam, because sometimes email app buttons are a little close together. I went to the spam box and marked it as non-spam, but now all of the emails I send to that address are soft bouncing.
I unsubscribed and resubscribed that email address, and I received the welcome email confirming my subscription, but mass send promo emails are now bouncing back. Is there a way to resolve this, or is yahoo just going to block those emails forever?
