Email address validation is the process of checking the validity of an email address. This helps to prevent sending invalid email messages and improving the delivery rate of your messages. By ensuring that only valid emails are sent to your recipients, you can improve your reputation and your sender status.

How can I verify if an email address is valid?

The validity of an email address is determined by its adherence to a set of rules. These rules can be found in a regular expression or API. Once you have your list of email addresses, you can use an API to validate them, allowing you to eliminate invalid or disposable emails.

One of the best API’s for email validation is Mailboxlayer. It is free to use and highly secure. It uses 256-bit HTTPS encryption to protect your data. Using an API is a great way to automate email validation while also measuring your email’s deliverability.

Besides preventing spam complaints and decreasing the number of bounced emails, proper email list hygiene can also reduce the costs associated with mailing. An accurate list will reduce the number of bounced-back messages and the cost of data storage fees. A high-quality list also increases the chances of your emails reaching the inbox.

Several Internet Service Providers (ISPs) have built-in email validation functionality. In addition to checking whether an email address is valid, an email validator will also check that the mailbox can receive messages and that the email server can accept it.

Some email validation tools will even detect errors in the email’s format. This can help you identify spam traps, as well as potential typos.
