why validate email addresses?

As a professional digital marketer, you understand that the quality of your customer data is vital to your success.

Typically, up to 40% of users signing up to your business through online registration forms can be dud email addresses. Dud email addresses can harm your business in the following ways:

  • Direct costs - dealing with bad email addresses such as bounce backs in your email marketing campaigns. Does your business perhaps employ someone who will make more productive use of time rather than wasting time removing bounce backs from your mail sends?
  • Lost opportunity - a potential customer doesn't care that they made a mistake inputting their data into your online forms. They will simply go elsewhere when your back end systems fail to get in touch with them by email.

With effective email address validation technology, you can do something about the following unpleasant side effects of doing business online.

how email validation technology helps your business

Right now, your business can successfully filter the following at the point of data entry by either your customer or your data entry staff:

  • Typos - a simple case of a mistaken keypress can cause your customer problems signing up for your service. Your business can lose the opportunity simply because your lead typed an incorrect email address.
  • Tyre kickers - users that are really not interested in paying for your service, try to "game" your systems by using fake or disposable email addresses. Separate the serious potentials from the time wasters.
  • Genuinely bad addresses - detect a wide range of dud emails and the reasons why including: full mail box, mail box not present, catch all addresses, spam-traps and more.
  • The genuine, confirmed, good email addresses - these are the ones that you want! Genuine, validated email addresses that add value to your business.

With the real time services, you get all of this information available to your business in real time either through our modern user portal or directly to your business application by API.
