What is a Non-Existent Domain?
A non-existent domain refers to a domain that does not exist or is not registered. In the context of
Email Marketing, it means that any email sent to an address at that domain will not be delivered because the domain does not have any associated mail servers.
1.
Bounce Rates: Emails sent to non-existent domains will bounce back, increasing your bounce rate.
2.
Sender Reputation: High bounce rates can damage your
sender reputation, making it more likely that your emails will be marked as spam.
3.
Deliverability: Poor sender reputation can lead to a lower
email deliverability rate, meaning fewer of your emails will reach the intended recipients.
Why Do Non-Existent Domains Appear in Email Lists?
Non-existent domains can appear in email lists due to several reasons:
-
Typos: Simple typographical errors can lead to non-existent domain addresses.
-
Fake Sign-Ups: Some users might provide false email addresses, leading to non-existent domains.
-
Outdated Lists: Domains may have existed at one point but were later deactivated or not renewed.
1.
Email Verification Services: These services can help you
