What is email address validation?

Email validation is the process of verifying the legitimacy and activeness of an email address, and features process checks including:

Syntax check

Syntax refers to the structure and format of the email address. Every email address shares the same structure: username, followed by an @ symbol, followed by the domain name. Email validation will check that the username and domain name are correctly formatted without any spaces or other errors.

Domain validation checks

The domain name is the final part of an email address following, such as or Email validation will check whether the domain exists, is active, is not a disposable address, or is not on a spam or scam list.

Mailbox checks

The mailbox is where the emails will be sent and delivered to. Email validation will check if the mailbox is currently in use, can receive emails and whether or not it belongs to a temporary email address provider.


Why should my business use an email verification tool?

Email verification tools are cost-effective and time-saving ways to cleanse your email database and are used by thousands of businesses across the world. By checking whether an email address is valid, active, and real, you can save a lot of time and money, whilst also finding out more about your customers.

Improved deliverability rate

Invalid email addresses lead to emails bouncing, which has a negative impact on your sender’s reputation and email deliverability. By validating your email addresses and using a clean list, you will improve your email deliverability rate, reduce your bounce rate and ensure your emails reach the right people.

Save time & resources

Manually validating a single email address doesn’t take too long, however, when you need to check many, it can be a long-draining process resulting in inconsistencies. Hopewiser lets you work smarter, validating emails in bulk – processing thousands of emails at once, which not only saves time and resources but also ensures there are no bad email addresses in your list.

Save money

Along with saving valuable resources from manual validation, you also save money by only paying for what you need. Many email campaign platforms, such as Mailchimp or Klaviyo, will charge you based on how many contacts you have on the system. So by having a clean email list, you can be sure that you are only paying for legible email addresses which have a chance of a conversion.
