Update and Check Email Database

Update and Check Email Database

Customers delete, change, transfer, and even sell their mailing addresses in a year. Therefore, it is important to check the base before bulk sending.

Run the email list through the validator and clean up unnecessary emails: non-existent accounts, contacts with complaints, users who unsubscribe from your emails.

Let’s summarize and use the following tips:

  • Check the collected contact base. Clean up the list and delete invalid mailboxes once or twice a year.
  • Use an email verification. Find the best works for you and your team.
  • Don’t send emails from your primary domain.
  • Don’t buy ready-made email contact lists. Build your customer base. Use the website, advertisements, questionnaires, call tracking, polls, and email finders.

A relevant and valid email database is the most crucial part of any marketing activity.

Address Syntax and Format Checking

The email verification tool checks email for:

  • Errors before and after the @ symbol. The first part of the address is called local, the second – domain:, For example, a user can skip a letter in a domain name: “.co” to “.com”.
  • Duplicate addresses.
  • Spam traps. These are the addresses that services use to check for unscrupulous senders. Because of such contact in your address book, you can get blocked by the mailing service. The validator checks the list of known spam traps and shows the matches.
  • Service addresses. This is the mail that is assigned to a group or department in a company — for example, admin@, support@, hello@. A big number of complaints come from these addresses.
  • Disposable emails are addresses for temporary use that do not require registration. Users use them in order not to receive a mailing from companies and not to give access to the main email. The email verifier finds such mail and offers to delete it from the contact database.

Validating emails allows any marketing specialist to reduce ineffective moves and reach maximum efficiency per every cent spent.
