Frequently asked questions

Email validation, or email verification, determines whether an email address is valid or invalid. The process includes verifying that the address uses the correct syntax and is error-free. From there, email validation consists of checks determining whether an address is in use or outdated. In addition to detecting validity, email validation grants insights regarding the email address type to determine if an email address is safe or too risky to use for your campaigns.

Email validation is important as it protects you from high email bounce rates. After using email validation to detect invalid email addresses on your list, you can remove them before hitting send. Doing this ensures that your email messages are sent to actual recipients so that you can maximize your engagement and gather accurate campaign data. Email validation doesn’t just aid with bounce rates but also helps improve your email sender reputation.

Email verification and email validation work hand-in-hand but are different processes for determining the validity and quality of an email address. Email verification is an email check that determines if the address exists and is currently used by the owner. Email validation involves a more in-depth examination, which can detect attributes such as the address type and problems that may impact email deliverability and engagement, such as mail server configuration or spam complaint history. ZeroBounce’s email validation uses both and consists of more than a dozen steps to protect your sender reputation better.

Email validation is primarily used by email marketers and any business that uses email for mass communications. Due to the high volume of emails these companies send regularly, it’s imperative to ensure that the email list consists of only quality, valid email addresses. If too many invalid or high-risk emails are present, bounce rates quickly increase, and engagement rates suffer.

The accuracy of email validation depends on the proprietary technology used and the types of verification and validation checks employed. Email validation is generally more accurate than standard email verification due to the additional checks required for validation. Nevertheless, email verification is still essential for preventing fraudulent emails from making it onto your list. Most top email verifiers promote 95% or higher accuracy. It’s recommended to research each email validation service to determine which email address types they can detect and whether they guarantee their accuracy claims.

The benefits of email validation include lower email bounce rates, better email deliverability, consistent inbox placement, high open rates, and improved email marketing ROI. In addition to these email validation benefits, your improved email marketing metrics will positively impact your domain’s sender reputation.

Verify+ from ZeroBounce is a free and optional enhanced email verification service, which is specifically effective for validating Yahoo and AOL email addresses. In 2018, Yahoo began disabling email accounts that were inactive for more than a year. However, validating these emails will still typically yield a “valid” result, as these accounts are still disabled. Verify+ from ZeroBounce is able to validate these accounts accurately by checking for bounces and returning a response based on the result.
