Email validation is a crucial element of ensuring that your data is clean and reliable. Using a validator API for your platform’s signup forms will ensure that you are only capturing valid email addresses, and preventing spoofed or fake email addresses from entering into your system. This will help you reduce bounce rates, clean up your list of subscribers and improve the overall sender reputation of your brand.

While some email validator API  have a standard result field that simply states whether or not an email is valid, the best ones will provide you with more detailed results. This includes the score, which is a percentage indicating the likelihood that an email address is valid. It can also include information such as the domain type, which indicates whether an email is a personal or business email. This will help you to determine the best approach for your platform, whether it is to display a warning message for invalid email addresses within your form or to drop them from the database.

In addition, some email verification services can also return details such as the first seen date and the spam trap score which helps to identify if an address is a common spoofed or used for phishing attacks. Additionally, there are some APIs that offer the ability to perform real-time on demand lookups, allowing you to validate email addresses as they are being entered into your platform. This will help to prevent any fraud email addresses from being able to enter your database and potentially harm your sender reputation.
