Email Validation

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.

At AFD Software, we make it easy for you to check email addresses are live wherever they are entered, by staff or customers, using a 3-point email check system.

When contacting students, we found multiple instances where the email addresses and phone numbers provided were wrong.

Preventing one or two students from slipping through the net, because they would otherwise miss a key communication and fail to enrol, more than covers the cost of email validation and phone validation from AFD.
