I have submitted several model releases that have been rejected because the e-mails bounced? All of the e-mails can't be wrong. Why are teh e-mail addresses bouncing?
Which email addresses are you referring to? Addresses listed on the Model Releases?
I assume Adobe Stock sent you an e-mail requesting model releases. DO NOT reply to that e-mail. Instead please log-in to your Contributor's Portal to upload model releases. See link below for details.
