Email verification has probably caused you a headache or more.

And you probably bother yourself with email verification because you know it’s important to your email marketing.

How does Email Validation work?

Email validation tools run a quick check to determine whether the entered email addresses are either valid, risky, or invalid.

Valid: the email address exists, and it is error-free. This verification will be complete till the mailbox level.

Risky: the recipient exists but there are other factors that indicate that sending emails to this address will bounce.

Invalid: the email address contains syntax errors, DNS errors, and/or mailbox errors.

How Does Email Validation Help?

Here are a few of the email validation’s benefits:

1. Email validation reduces bounce rate up to 98%, thus improving your email deliverability by removing all invalid email addresses from your list.

2. Email validation helps you to maintain a high Sender Score.

3. Email validation saves you money by increasing your revenue, and by not sending emails to invalid email addresses.

4. Email validation gives you a higher conversion rate, as you will be sending your emails to the right email addresses.

How can I check if my email is valid?

Here is how you can check to verify the validity of an email address:

  • Free email verifier tools: very convenient if you’re sending less than 50 emails campaigns or you verify an email address every now and then.
  • Email finder tools with built-in verification: If you’re scaling email campaigns and can’t risk email bounces, an email finder tool will automatically find and verify any given email address.

Whether you are verifying one-by-one email addresses or bulk email lists, verifying an email address without sending an email is pretty simple.

Why valid e-mail addresses are important… And invalid ones can be dangerous!

Email validation is important because emails go bad quickly – especially in times of recessions.

This happens because businesses go out of business at a high rate and people leave or lose their jobs.

When businesses cease to exist or people are led out, the domains get dropped and emails become invalid.

So a bulk email verification service ensures that you identify and remove invalid email addresses, spam traps, etc.

Removing invalid email addresses helps you maintain your IP reputation.

A low IP reputation means your email campaigns will not land in your recipients’ inboxes, but rather in their Spam folders.

What’s the difference between invalid and valid email addresses?

Valid email addresses are related to an active and engaged recipient who adds value to your marketing campaigns.

A valid email address has the right format and belongs to an email domain.

Invalid email addresses are related to an inactive and engaged recipient.

The unengaged email addresses are invalid for a few reasons:

  • Invalid emails can have typos or invalid formats that are not related to a legitimate inbox: recipients can make spelling errors in the email address’s format by accident during typing.
  • Invalid emails if the user changes their email, which makes the email not related to a user:  Inactivity or lack of engagement of certain email addresses is the reason behind how emails become invalid.
  • A person may switch inbox providers, or create a new email address within the same provider:  When an inbox provider or a server is permanently down, all email domains under that provider become “dead.”

What to Do with Invalid Email Addresses

What should you do with invalid email addresses?

If an email address is simply unengaged but valid, you can utilize a few re-engagement email strategies.

You can send a reintroduction email or, if your CRM is up-to-date, engage with the recipient on another platform.

However, if an email address is invalid, you need to archive or delete the invalid email.

You should also add the invalid email to the opt-out or unsubscribe list.

This prevents you from accidentally sending a campaign to an invalid email address.

A common example is if you send an email to someone who is no longer at a company.

Most companies won’t let you know about a change in staff.

However, if the email is linked to a person that no longer works at the company, their emails are usually auto-forwarded to a new contact.

If the new contact sends you their valid email address, update your CRM with the new address and archive or delete the old, invalid email.

You should also add the old email to the opt-out or unsubscribe list.

The best way to delete invalid email addresses?

The first step you should archive or delete invalid emails, also make sure to add the invalid email to the opt-out or unsubscribe list.

This way you prevent sending a campaign to an invalid email address.

For unengaged but valid email addresses, you can use these email addresses in re-engagement email strategies.

If your CRM is up-to-date, you can send engage with the recipient on another platform, you can send reintroduction emails.

There is also the example of if the email is linked to a person that no longer works at the company, their emails are usually auto-forwarded to a new contact.

If the new contact sends you back an email with their valid email address, update your CRM with the new address and archive or delete the old, invalid email.

However, make sure to add the old email to the opt-out or unsubscribe list.

How can I check if my e-mail address is valid?

The best way to validate an email address is to use an email checker.

An email checker will check if the email addresses have the correct syntax and are valid and deliverable.

You can also manually validate an email address by sending an email to the address to see if the message is bounced back to you or if the recipient responds to your email.

Perform an IP Address Lookup

IP address lookup helps you to determine the geolocation of an IP address.

Each email message has the IP address of the server where it comes from.

By default, you won’t be able to see the IP address since it’s hidden in the source code of the email message.

Here are the steps:

1. Look for the email message’s source, look under “received from” to find the IP address.

2. Copy the IP address and paste it into an online IP address lookup tool, like What Is My IP Address.

You will get the ISP and organization associated with the IP address as well as its location.

If the IP address is located in a foreign and far country, someone could be spoofing it.

While IP Address lookup can tell you where an IP address is from, it can’t tell you about the address’s deliverability and if it has a reputable domain.

If you have a large number of IP addresses to check, this process can be time-consuming for you as an email marketer.

E-mail checker

Email checkers, also known as email verifiers, can validate email addresses.

Free email checkers typically have a limited number of addresses you can check in a month or a day.

To check more email addresses, you need to subscribe to a service.

There are many services to choose from, while each tool is different, all email verification tools are easy to use.

Plus, some email verification tools don’t require you to register.

Password recovery

For password recovery, Google, Yahoo, and Microsoft (the three major email providers) use an email address checker for password recovery.

The password recovery process can tell you if the entered email address’s form is correct.

If you receive a message from a @gmail.com, @yahoo.com, or @outlook.com domain, you can check email addresses in your favor:

1. Go to the corresponding recovery page

2. Enter the address that you want to verify

This method to check emails is also time-consuming and can be underperforming.

As an email marketer with thousands of email addresses list, you can’t possibly be doing this process for each single email address.

Search the Address in Google

Searching email addresses in Google will reveal if the email address is valid or not.

However, it won’t tell you that an email address is fake.

This method is manual and open to the public since most people have a presence on the internet, either through websites, Linkedin, etc.

Google or Bing constantly crawl the internet, indexing new information around the clock.

That’s why real addresses linked to real accounts are easily found with a simple search engine query, while fake email addresses aren’t.

Send an Email to the Address

This is the most straightforward way how to check if an email is valid or not.

Sending an email directly to the address works great for email marketers with a small marketing list.

This option is great if you add a few email addresses to your email list each month.

If you send an email to a fake address, your email will bounce back, and you receive one of these messages from your email provider:

Message not Delivered: There was a problem delivering your message to [email protected]. See the technical details below or resend the email in a few minutes.

Address not Found: Your message wasn’t delivered to [email protected] because the address couldn’t be found. Check for typos or unnecessary spaces and try again.

There is also the case that you will not receive a message from your email provider.

This happens because some email providers use a catch-all email address to catch emails sent to incorrect addresses.

When you send an email to a catch-all address, your email will be delivered but not to your intended recipient.

How can I check if an email address is valid for free?

You can use an email validation service, it’s the best option.

Many email verification services provide a web tool on their website where you can quickly verify the address in real-time.

The email verification service does all the work of checking the syntax and reviewing the MX records for you.

What happens if you send an email to an invalid address?

In most cases, the email server could fail to recognize email addresses.

Which will result in receiving a bounce about how the address is undeliverable.

In some cases, the email may be delivered to a catch-all address, and you won’t receive a message informing you the email address is invalid.
