What is real-time email verification?

Email verification is a common method to prove you’re a real conscious human person – for the purposes on safe online transactions. A message with a link is sent to the user, and he has to click on it to verify his/her sign-up, order, subscription or comment. This process is of the most significance in transactions involving money, such as online banking. Though in modern fast-pace reality it becomes even more important to validate data as quick as possible. And preferably instantly, in real time, so tools and services for real-time email verification emerged.

Being one of the ways to guarantee the collection of real and right user data on the early stage – before emails enter a database, is also an opportunity to turn users to customers. As a business, you want clean email lists to increase sales and, of course, no risks of fraud. Thus, when a user signs up on your website or app, you want to avoid fake/wrong emails right there. You don’t want misspelled addresses or fake accounts of someone fooling around. How do you do it?

What is real-time email verification?

Real-time email validation, or verification, is one of the solutions that a typical email verifier service offers. It can be free or paid for a certain amount of validations per period, depending on a company. To verify email addresses in real-time at point of entry, a connection is established between a user sign-up form and a validation service. This is usually done via API – a set of protocols in programming to set a communication between programs.

Such validation identifies common errors/typos (“gamil”, “mgail”, “gmail.cmo”, etc.), authenticates domains, syntax, and in some cases checks MX records (mail exchange) for existence of email address. It can be integrated into web forms, sign-up forms, forums and message boards, CRMs.

Benefits of real-time email verification are obvious:   

  • Clean email lists
  • Reduce bounces and increase CTR
  • Improve marketing/email campaigns
  • Reach more people to turn them into customers
  • Save time and opportunity to automate tasks
