Emails are the primary tools used in business operations to maintain communication with customers and potential clients. These emails are also the backbone of all marketing campaigns that businesses run to build brand awareness and attract new customers. In order to make sure that all your marketing efforts are reaching the right hands, you need a good and clean mailing list of valid and authentic emails. This is where an email verification API comes in handy. An email verification API automatically eliminates mistyped, disposable, inactive, invalid and potentially threatening email addresses from your registration and subscription forms. This way, you will never have to worry about your mailing list getting stale and lose out on sales or customer service opportunities.

An email verification API provides you with a set of functions that allows developers to check the validity of an email address. It can be used for multiple purposes such as cleaning databases and preventing the risk of spammy or invalid emails from being redirected to the user’s junk or Spam folders. Email verification is also useful for monitoring the overall health of an email list, as it helps you identify inactive or invalid addresses. It can also improve the overall delivery rates and sending reputation of your business by reducing bounce rates.

One of the best email validation services is ZeroBounce. The tool uses machine learning to provide detailed results and alert users of typos while they are still in the form fields. It is highly reliable and offers various pricing plans depending on your needs. Its features include the ability to check and verify global email addresses, 30+ status & sub-status codes, and more.

Another option is BriteVerify, which offers a simple and easy-to-use email validation solution for bulk emails. Its user-friendly interface makes it easy for developers to integrate the tool into their applications, and it is GDPR compliant. It can also detect and correct spelling mistakes, and it can filter out broken SMTP handshakes, spammy mailboxes, and URI DNSBLs.

It is important to note that some of the status and sub-status codes may be added or changed in the future. So, it is a good idea to always get verification results in JSON format for the most stable output.

The response to a verification request contains a list of the status and sub-status codes for each email address. The id and index of the verified email address are included in the response, along with the error message if the address is not valid.

If the error message is “no_mx” or “no_answer” it means that the email domain has a null MX (mail exchange) record and does not accept email messages. Invalid email addresses are often provided by disposable email providers or are part of a blacklist. This information is used to help prevent spamming and other abusive activities.
