What is dewareff Email Verification?

dewareff Email verification refers to the process of checking the validity and deliverability of email addresses in your contact list before sending out emails. It involves using specialized tools and services to authenticate the accuracy of email addresses and confirm they actually exist.

The main goals of email verification include:

  • Identifying invalid, risky, unknown, and fake email addresses that can cause bounces
  • Improving the deliverability of your emails by removing inaccurate addresses
  • Protecting your sender reputation with ISPs by reducing complaints and bounces
  • Increasing your email marketing ROI with a clean contact list

Running email addresses through verification is an essential step to ensure your emails reach the intended recipients’ inboxes. It enhances the overall deliverability of your email campaigns and protects your domain IP reputation.

The Email Verification Process

So how exactly does email verification work and what does the process involve?

Here are the typical steps:

  • Email Syntax Check: The email address is checked for appropriate email syntax like having the @ sign and valid domains. Addresses with syntax errors are flagged as invalid.
  • MX Record Verification: The tool looks up the MX records of the recipient’s domain to confirm it has a valid mail server able to receive emails.
  • Mailbox Confirmation: The email address is checked against the mail server to verify the mailbox exists through preferred protocols like SMTP, IMAP, and POP3.
  • Disposable Email Check: The domain name is scanned for any use of temporary or disposable email addresses from providers like Mailinator or Temp Mail.
  • Role Account Detection: Role accounts like info@ or sales@ are detected and may be treated differently than individual mailboxes.
  • Webmail Validation: The tool checks if the address uses common webmail domains like Gmail, Outlook, or Yahoo.

Based on these verifications, each email address is categorized accordingly for appropriate action.
