Why You Need an Email Validation Tool
It takes work to build a mailing list of prospective clients and keep that list up to date with valid and deliverable email addresses. Over time, people change addresses and spam accounts sign up for campaigns. After a while, mailings to those addresses bounce, decreasing the list’s deliverability rate. The result is that the organization’s marketing goals will be challenging to achieve.
When you know how to validate an email address using an email validation tool, you’ll save time determining if the addresses on your lists are deliverable and not spam, reduce your bounce rate, improve your sender reputation, and be assured that your mailings reach your subscribers.
Email validation tools look for potential issues and problems in an email address. The tool performs the following tasks to find these issues:
- Looks at the email address formatting and syntax to determine if it is valid and won’t result in a hard bounce.
- Checks the address against known spam traps so that your list will avoid being blocked by ISPs and ESPs.
- Verifies the domain where the address originates from to make sure the domain is registered.
- Uses the SMTP protocol to make sure the mailbox for that address exists and can receive messages.
How to Choose an Email Validation Tool for Your Business
As your mailing list grows and ages, it becomes more difficult to keep the list free of incorrect addresses and email addresses that have been closed. So, it’s a good idea to clean your lists with a validation tool regularly.
When looking for the best service that fits your needs, evaluate each potential service to determine if they provide the types of email verification tools you’ll need and the types of problem email addresses the service looks for. Do you need to validate addresses in bulk or perform real-time validation with an API? Does the service identify fake addresses, spam traps, catch-all addresses, inactive accounts, and role-based emails?
In addition, look at the service’s accuracy rate, API and automated integrations, customer support, speed, and price. You may also want to look at the level of control you’ll have over your list and the type of reports the service provides after validating your list.
