How To Validate Multiple Email Addresses (the Right Way)


You’ve asked the question, “How to validate multiple email addresses.” The real question is, is that the right question? 

Chances are you’re searching for a service to tell you if the emails in your list are active and deliverable. Validation will do that. What it won’t do is protect you from the deliverable, yet still dangerous emails in your email list. 

For that, you need something different. You need Email Hygiene.

So - the question you should be asking is, what’s the difference between Email Hygiene and email validation?

The difference between email validation, verification, and Email Hygiene 

Email Verification: Email verification is a real-time server ping verifying that the email ID exists, is active, and accepts email. 

Verification detects email addresses that are:

  • Valid
  • Invalid 
  • Unknown

Email Validation: Email validation uses a third-party data source to confirm valid email addresses. At Webbula, we use our dataVault, which is constantly updated, to validate verified emails against and ensure they are still active. This sets our validation service apart from competitors who use cached historical data. 

The challenge with cached data is that it gets older and more inaccurate with every moment, hour, and day that passes. Because our dataVault is constantly being updated and refreshed, our email validation results are more accurate than our competitors. 

Validation confirms that email addresses are:

  • Valid
  • Invalid
  • Unknown

Neither email verification nor email validation goes beyond determining any more than that. Many serious threats, like bots, disposable domains, and blocklisted emails, will pass verification and validation because they are active emails. 

Email Hygiene: Webbula’s Email Hygiene takes validation and verification a step further, determining which email addresses pose a threat to your deliverability and sender reputation. Not only that, Email Hygiene ranks those threats based on risk severity. 

How to properly manage the deliverability of your email list
