Validate Email Format In 2 Seconds

It takes only 2 seconds to validate email format by an API. Email-Checker’s email verification API is fast and reliable for correct formatting.

Note that the string IsValidEmail method does not perform real-time authentication to validate an email address online. It merely determines whether its format is valid for an email format.

Using regular expressions is probably the most known way to validate email format in JavaScript or other local unconnected coding. An API server formats and corrects an email in less than 2 seconds with 98% accuracy.

According the standard Internet specs set forth by the committees, there are a number of valid email address formats that can be tested against. You can learn those different ways and test email address of all formats one by one, or you can install an email verification API to do it for you.

An API will test the deliverability of any email in seconds and start sending back the results of the check very fast. Email-Checker verifies the format of an email address and validates if it is correct and looks the part.

Regular expressions only will check whether the string is a valid format, it does not check whether the mailbox exists. A API is the only technology available to do that level of validation.

A service like that is preferred for forms and input boxes online. Within a input field, we can verify if a email address entered exists and immediately validate email format. Strings won’t hang.

If given a string instead of an API call, scripts will return “true” if it is a valid email format and leave you guessing about the mailbox of the email address. Strings only checks whether the a valid format is in place, it can not check anything else.

If you want to know how you can validate whether a email address entered in a field or form is in proper format during the self-registration, try Email-Checker’s API.
