Accurate email validation can help ensure that your messages reach their intended recipients, improving campaign deliverability rates. It can also improve engagement by removing addresses that are likely to be marked as spam or result in hard and soft bounces, as well as those that may not exist.

The best email validation tools will perform various checks on your list to verify it for accuracy. These include identifying common formatting errors, checking the validity of the domain, and assessing whether or not the mailbox exists and is configured to receive emails. Many of these tools will also provide a score for each address, indicating how accurate it is and how risky it is to send to. Some will even give you more detailed explanations about why an address has been classified as inaccurate or high risk.

Accurate Email Validation: How to Improve Your Email Deliverability

Many of these services offer APIs that you can use to add email verification to your website forms, so you can check addresses as they are entered. This can help reduce errors and prevent people from using fake or disposable email addresses to sign up for your mailing lists, which can damage your reputation and hurt your email marketing campaigns.

While email validation is essential for ensuring that your messages reach their intended recipients, it cannot guarantee 100% deliverability. Other factors, such as the quality of your content and your email server’s policies, will also impact deliverability. As a result, it’s important to incorporate email validation into a comprehensive list hygiene strategy that includes CAN-SPAM compliance and other best practices.
