It is incredibly important to know how to check the database of email addresses for validity if you work in a company that deals with email marketing as a part of business strategy. Before sending out a mass mailing, you must first verify your email address list. After all, it ensures that letters are sent successfully and that a large percentage of them get delivered. There are particular services that can assist you so that you don’t have to do it yourself. Email validators are what they’re called. You can check a lot of things with their help:
- Syntax – incorrectly spelled emails: mistakes in domain spelling, missing “@” sign, etc.
- Duplicate emails.
- Spam traps – if you send a letter to one of these addresses, all subsequent mailings will be classified as spam for a long period.
- Contacts from which a lot of spam complaints are received.
- Disposable mailboxes – no one will ever read the mail coming to them.
- SMTP connection with the recipient’s server shows whether a particular email account actually exists.
