Checking email for validity. 15 best services.
Any company that sends bulk emails or uses email marketing needs to validate their contact base from time to time. There are special services for this - email validators. With their help, you can check:
- Syntax - incorrectly spelled emails: mistakes in domain spelling, missing “@” sign, etc.
- Duplicates are duplicate emails.
- Spam traps - if you send a letter to such a mailbox, all mailings will end up in spam for a long time.
- Contacts from which a lot of spam complaints are received.
- Disposable mailboxes - no one will ever read the mail coming to them.
- Role-based Addresses are determined by the position, not the person, with such emails there is a very high rate of complaints and unsubscriptions.
- Mail eXchanger (MX) - the main record for the mail domain; a domain that does not have such a record is not a mail domain, i.e. cannot receive mail.
- SMTP connection with the recipient's server - shows whether his email account actually exists.
- Contact active / inactive - whether the user is currently using the specified mailbox.
This is not a complete checklist, yet it does a good job of demonstrating how many dangers there are in an unverified contact base. For example, if contacts were collected offline - through questionnaires, polls or flyers. Or if Double Opt In has not been configured in the registration form on the site - a mandatory confirmation of the subscription.
Mailing to an unreliable contact base is:
- A waste of money;
- The risk of being blacklisted by mail servers;
- Spoiled reputation of the sender;
- Blocking in ESP.
