Email Validation Vs. Email Verification

It’s best to understand what email validation is? And why is it different from email verification?

A valid email address can host messages from other senders. If you don’t know, one in five people voluntarily lists an incorrect email address.

That’s the reason email validation is crucial. It’s the result of the email verification process. It also means reviewing any extra information attached to the lead’s email to validate it. In contrast, email verification is all about examining and verifying an email address to check whether it is active or not.

The way cold emails work now has changed. From email personalization to email validation and selecting the right person’s inbox, things have changed. But it still works the same. Email validation keeps your list of prospects fresh, reduces bots and spams traps, and elevates email deliverability rates.

Email validation is crucial since it verifies newly received email addresses in real-time, even before you hit the “send button.”

This helps you in protecting your brand from any catastrophic event in the future.

How to Properly Validate Your Emails ?

Let’s dive into how you can correctly validate your emails?

  • Using APIs

An API initiates a direct link between your email list or program to an email verification database.

Email validation API tools view your mailing list and scan it for any misspelling or typo in email addresses, domains (Gmail, Yahoo), or spammed email IDs to ensure 100% deliverability. It helps in verifying all the properties and validates the email in the best way.

It detects name, syntax, DEA, and spam trap, and active mailbox check. Just to ensure that you’re reaching the right recipient’s inbox. This ultimately reduces bounce rates, and you can easily check emails in real-time for bulk validation.

  • Send Test Emails

You can also choose an easy path for email validation. Send a test email to your dummy id or email address.

This tactic can render issues aside. It can help you check issues like blocked emails, spam filters, fake or invalid email addresses in such a manner that when you send an email, it lands in the right person’s inbox.

You can easily verify all the details of the email before sending it. It’s the most straightforward technique. If your prospects’ email address is fake or invalid, it will bounce back, and you will receive an error email showing “letter wasn’t delivered or the “address wasn’t found.”

So, use a dummy account to send test emails.

  • Check Correct Syntax Errors

We often check emails based on these (@) symbols, which are not enough. To validate an email address, you need to consider other features like syntax errors.

In short, malformed or incomplete email addresses are interpreted as syntax errors. They won’t be added to your email validation process since the syntax plays a great role.

We are humans, and we often make mistakes while doing things manually, even if it is entering an email address. You can make typo errors, commas, or misspellings. While making mistakes is fine, your email can be fallacious and invalid when cold emailing.

So, look for syntax errors before sending any cold email.

Double opt-in Method

Email list validation states that single opt-in emails help your email list increase up to 25% faster. This return on Single Opt-in appears in huge numbers of email validation.

The double opt-in technique is a popular technique that prevents spam users from registering with fake accounts. It levels up the process of eliminating invalid email addresses. Now, if a viewer is not interested in your brand and enters an invalid email address (purposely), the double opt-in email will leave no chance of re-connecting with that viewer.

  • Re-typo Method

Double typing is a process that allows users to avoid typos or syntax mistakes. It ensures that your emails are typed correctly. If you can make them enter their email address twice, they will be alerted and not repeat the same typo error they did previously.

Hence entering a valid email address will become a compulsion, not a choice.


Cold email isn’t going anywhere soon. So, it’s best to leverage the cold email process and play the number games.

And before you send your first cold email, verify, validate, and then hit the “send” button. This will save your time, energy, and money which you need to establish your business.
