The email lists obtained by enterprises from website registration, exhibitions, CRM and third-party channels usually contain addresses with format errors, invalid or abnormal status. If used without verification, it will increase email bounce and data processing costs.
It is impossible to quickly determine whether the email address is currently real and valid.
Historical customer mailboxes may have been deactivated or have lost value.
A large number of incorrect email addresses are mixed into the database, affecting the overall quality of the list
Manual verification of mailboxes one by one is inefficient and cannot handle large files.
The lack of unified test results makes subsequent screening and sorting difficult.
