If your recipient's inbox is full, or the email doesn't exist you will get what is called a bounce. Read more about these here.
Invalid email means that the server has not been able to identify the email address, the address contains invalid characters (parenthesis, colon, semicolon, etc.), or is written incorrectly.
Unfortunately, if your contact is missing an email address we can't send them any emails. Go to the contact page and edit the contact’s information.
Email was rejected
Emails can be rejected by a number of reasons:
- Your email domain isn't verified with Upsales.
- The size of the email is too large; check your attachments and images, a total size of 15MB is considered standard.
- The recipient's inbox is currently full.
The contacts that are marked as inactive are sorted out before an email campaign is sent and will not receive your email. They will still be visible in your segment and recipient list.
You can reactivate the contact on their Contact page.
Select the Previously Unsubscribed tab to see the contacts who have unsubscribed at an earlier date. These contacts will not receive your email campaigns.
