Postcoder email validation is easy to integrate into the existing user-input forms on your website or app.
Postcoder validates the email address in real-time
Postcoder performs a range of live checks to verify the email address can actually receive email.
You capture a valid email address every time
Postcoder lets you know whether the email is valid, and highlights typos and disposable domains.
