Email checker  is a critical part of your email marketing strategy. Without it, you risk sending emails to fake or invalid email addresses which can result in high bounce rates, damage your reputation as a sender, get you added to spam lists, and mess up your metrics. Using a free email checker or an automated system to validate and verify emails is one way of reducing your bounce rate and making sure that you are reaching your audience.

There are many different email checker tools available on the internet. Some are very simple and will only check whether an email address is valid by checking for certain basic criteria such as the ‘@’ sign or syntax. Others will check the MX records to make sure that the mailbox actually exists and is accessible. These types of checks are much more complicated and can take a long time to complete.
