In the perfect world of Email Validation, there are only two answers: email address is valid or email address is not valid. But in the real world, there are other answers which make email validation process more complicated. When DeBounce servers try to reach an external server, these results may obtained:
- Email is Valid
- Email is Bounce
- Server is Accept-all
- There is no definite response - Unknown
Accept-all is also known as an “Catch-all”, is a domain-wide setting where all emails on this domain will be reported as a catch-all. There is no definitive way to determine whether this email is valid or not. DeBounce has unique methods to validate accept-all emails.
Catch-all servers that DeBounce can validate
Validate QQ.com and Mail.ru Emails
QQ.com (also foxmail.com) and Mail.ru (also list.ru, bk.ru and inbox.ru) domains are Accept-all and this is why all email validation services are not able to validate these domains (Read full article: What is a "Catch-all" or "Accept-all").
The good news is, DeBounce has unique techniques which can validate some accept-all servers. QQ.com and Mail.ru are included in servers which our engine can validate. This is an important achievement because based on Wikipedia, as of June 2016, 899 million active QQ accounts were recorded. Moreover, Mail.Ru's sites reach approximately 86% of Russian Internet users on a monthly basis and the company is in the top 5 of largest Internet companies, based on the number of total pages viewed. It's easy to guess how many QQ.com and Mail.ru emails maybe exist in an email list. DeBounce can easily check if QQ and Mail.ru emails are valid; despite both are accept-all.
