Email Validation

Have you implemented email address checking from AFD Software?

A simple mistake in typing an email address makes it impossible for an email to reach the right recipient. For a business or service-based organisation this can be costly to both revenue and reputation. An enquiry from a prospective customer appears not to have been answered or an order goes unfulfilled.

AFD Software make it easy for businesses to check email addresses wherever they are entered by staff or customers. There are three checks:

Some services check only syntax, some only domain and many do not check the local part. Email address validation from AFD Software checks all three: Syntax, Domain and the Local Part.

It is not always possible to validate the full email address at each domain – however, whenever it is at all possible the AFD email validation service will do so.
