Email validation is a process of verifying the accuracy and validity of an email address. It is important to verify email addresses before sending out any communication, as invalid or inaccurate email addresses can result in undelivered or bounced messages.
There are a number of different methods that can be used to validate an email address, including checking the syntax, domain name, and user account. Additionally, many email validation services also offer additional features such as checking for disposable or temporary email addresses.
The best email validation service will depend on your specific needs and requirements. However, some popular options include Email Hippo, Kickbox, and MailboxValidator.
