Improve Email Deliverability with Email Validation

  0 reviews

A clean email list is essential to email marketing success. Gone are the days when spam filters just looked for certain words in the subject line. Now your ability to deliver email is determined by your email reputation: the number of bounces, complaints, and spam trap hits caused by your mailings. When you exceed the thresholds set by ISPs or your email service provider, your mail can be sent to the junk folder or even blocked. Email list cleaning can improve your email reputation and increase your inbox delivery rate by removing invalid and problematic email addresses from your list.

TowerData Email Validation provides a comprehensive, easy-to-use set of features to scrutinize email addresses for accuracy and authenticity and repair them when possible. When validating email addresses, we start by confirming that the structure of the address conforms to Internet standards and ISP rules. Free validation tools stop at checking for valid characters and the presence of an ‘@’ sign. We confirm that the email uses a valid top level domain (e.g. .com, .uk), detect invalid formats for top ISPs (e.g. AOL emails do not start with a number), and identify advanced syntax errors (e.g. domains cannot start with a hyphen).
