Email validation, verification, and list hygiene services have advantages and disadvantages.

Email validation


In most cases, you will get a report from a cheap email validation provider informing you whether or not your email has been verified.

  • Valid. In some cases, this means that the email has been validated and is accurate, while in others, it means that the email is genuine and accepting messages.
  • Invalid. Because your email validation service has confirmed this email’s existence, it does not exist. Or, it’s not taking any messages at this time. Entries that do not fulfill the functional requirements to act as an email fall into this category.
  • Unknown. The status of an email address is included in this category. Emails that didn’t make it past the validation procedure fall into this category. There are certain cases when an SMTP server accepts any emails sent to its domain, even if the sender does not have a valid account linked with the environment.
  • Do not send this message. Certain email validation companies give legitimate emails yet contain terrible news for the sender in their category. Email addresses having a history of spam complaints or ties to questionable websites may fall into this category. Depending on the service, extra inspections and hygiene activities may be included. An email verification or list hygiene service generates findings beyond the basic types by providing value and risk-related information about each email address.

What’s the difference between email verification and validation?

In addition to ensuring that an email address is “functionally genuine and exists,” email verification goes further. An account may be verified as active and linked to a natural person using public and proprietary data. This aids in the eradication of inactive subscribers and spammers from your mailing lists. The more thorough a service provider’s verification procedure is, the more information they can supply you with your customers. All of the following status categories may be included in a verification service report:

  • Duplicate. The email addresses you’ve supplied for evaluation will be compared to your current list by a list hygiene service, and any duplicate addresses will be identified.
  • Catch-all. Catch-all accounts capture emails sent to a legitimate domain, but emails sent to an existing address are not. To ensure that they get everything submitted to their environment, a company may utilize a catch-all address. Those signals, on the other hand, are being ignored.
  • Role-based. may be used by a corporation to collect generic messages (e.g., [email protected] or [email protected]) that an individual does not own.
  • Obtain a free email address. Some people use a free email account that isn’t the wrong kind of lead. Some B2B marketers, on the other hand, choose to use just addresses from other companies’ domains when compiling their lists.
  • Auto-generated or random number. Throwaway or false accounts or bots are more likely to be linked to an address made up of random characters than legible ones. Even if an address is connected with a genuine domain, certain services may block it if it seems to be produced automatically.
  • The spam trap. There is no actual customer here, and you are being tested on your email hygiene. It’s not uncommon for a formerly active email to become a spam trap. Keeping an eye on your subscriber list and implementing a sunset strategy may help you avoid this.
  • The toxic area. Sender domains aren’t the only ones that might suffer from a negative reputation. Spam distribution, bot email creation, and other disruptive conduct are hallmarks of toxic domains. You don’t wish to receive emails from these domains.
