Email validation check is a simple but vital tool that ensures you have high-quality contacts in your database and reduces the risk of costly deliverability issues. This is a key component to maintaining a strong email marketing program and improving your overall profitability.

While most marketers know that email address verification is important, many don’t understand exactly how it works. In a nutshell, email validation checks that an email address is properly formatted and actually exists by performing a series of tests on the email server. This includes looking at the MX and DNS records to confirm that the domain is active and that the mailbox is accessible. It also checks that the email address is not a spam trap or known complainer, which could hurt your reputation and lower your delivery rate.

Email Validation Check: Why It’s Vital for Effective Communication

When choosing an email validation check, look for one that has a high accuracy rate to avoid the risk of inaccurately flagging legitimate addresses as invalid. Also, be sure to evaluate the provider’s resources and support, especially if you’re using a free tool that has limits on the number of emails it can validate in a given period.

Adding real-time email verification to your signup forms is an easy way to improve the quality of your email list. It instantly weeds out invalid addresses, such as those belonging to bots, spam traps and known complainers, so you can be confident that your email campaigns are reaching their intended recipients.
