Email address checkers can improve your open rates

20 Bulk Email address checker Software Solutions:

Updated 16 October 2019:

An email address checker is essential because email marketing can be one of the most effective ways of acquiring new customers and reactivating existing customers. However, research suggests that on the average contact list around 60% of emails are inactive as email address checker software is not regularly used.  So less than half of your contacts may be receiving your communication and have a chance of opening it. This can seriously damage the effectiveness of email campaigns by reducing your conversion rate.

For this reason email address checker software is important to consider when planning your email marketing strategy. It may be a false economy if you don’t  invest in real-time solutions to check and verify email addresses when you first capture them.

You should also regularly conduct data cleansing of your lists to maintain the quality of existing customer contact details. Email address checker solutions will normally validate the format of emails, remove duplicates, remove role emails (e.g. sales@), compare against a bounce file, compare against a complainers file and remove disposable emails.
