The Purpose of Email Validation Tool

Every marketing campaign needs an email validation tool. The key to effective email marketing is email deliverability.

Sending messages to invalid email addresses repeatedly is the fastest way to lose deliverability.

Even if you start with a clean and high-quality mailing list, we strongly advise you to validate email addresses periodically, as some emails may become obsolete after 3-6 months.

Who needs email verification?

Invalid emails increase bounce rates, complaints, and ultimately harm your reputation. Your list may be of poor quality if obtained illegally or become obsolete after months of inactivity. So all email lists need regular cleaning.

Email Verification Tool Types

To remove suspicious or non-working emails that may harm your deliverability. The differences between tools are in the ease of use, validation performed, accuracy and reliability, assistance, and lastly, price. Let’s look at the three main email verification tools:

1. Automated Verification Tools

B2B mailing lists usually deteriorate slowly. Based on your settings, automated email verification tools check your database and alert you if your lists need cleaning.

2. Real-time Verification

Real-time email verification tools allow you to inspect and delete emails as they arrive. Using a CAPTCHA with double opt-in has the same result – you keep sending messages to at least one invalid email address. A real-time tool will also detect incorrect email input.

3. Bulk Verification Tools

Upload an email list to find out which emails are working, invalid, and dangerous. Several tools require a.csv file, but most marketing automation systems handle this task automatically. Bulk email verification tools work well if you have an old or stolen list. However, sending massive amounts of emails at the same time will continue to harm your deliverability. Consider slowing mass sending if you suspect your list’s quality.
