What is email validation and why is it important?

Valid email addresses are essential for any company hoping to succeed with email marketing and customer communication. It’s critical to double-check your email address list is correct, error-free, and that the emails actually exist. People make mistakes, it happens, it’s not uncommon for your customers and subscribers to make typos in their email addresses during input. And if these typos go unnoticed and uncorrected into your database, you will not only lose contact with that customer, but also have an overall bad effect on your overall deliverability score as more of your emails bounce.

We’ve put together a handy guide advising how to check if an email is valid, why it’s important for your marketing strategies and sales communications, and how Fetchify could make life so much easier for you.


What is email validation?

Email validation is a method of determining whether or not an email address is reachable and valid. It executes a quick process that detects typos, whether they are honest errors or deliberate misdirection. It also verifies whether a specific email address is associated with a reputable domain. This tool not only checks email addresses at point of entry into your database, it also protects your email sender score, allowing you to get the most out of your email software.

It’s not enough to simply be checking for an @ symbol in your email field, or for a full stop and a standardised suffix. These only verify that a customer’s email address is properly formatted. Just identifying correct format doesn’t check if an email address works and is linked to a valid, frequently used inbox. This means you won’t realise it’s invalid until you try to contact the customers or prospect. Whether it’s for signup confirmation or an email campaign, if too many of your emails bounce back, you could end up automatically being filed into junk folders.


Why is email validation important?

Email marketing is essential for eCommerce firms because it allows you to connect with customers instantly without depending on social media algorithms or search engine results. It has a significantly lower risk than social media advertising. Your subscriber list is yours to keep and your communications are delivered directly to them, even if you switch platforms. That implies you can’t lose your ability to interact with them due to an algorithm change, a failure of an external firm, or an arbitrary ban.



Here are some great benefits of email marketing:

It boosts brand recognition – consumers who follow you indicate that they are interested in your business

  • It is incredibly measurable, allowing you to diagnose issues and identify areas where you can improve
  • It’s cost-effective
  • Because some purchasers are in the research, comparison, or ready-to-buy stages, personalised messaging is possible, customised to their stage in the buyer journey.

Whether email marketing is your main method of communicating with clients or just one of several different channels, verifying customer email addresses at the time of entry/capture is a primary priority in order to maximise your campaign’s contactable audience and readability. Having verified email addresses could reduce your bounce rate by up to 98%1, which is a staggering statistic. It can also help with increasing your conversion rate as you can be sure your campaigns are going to the correct email addresses every time.
