When sending emails to an extensive list of recipients, it’s important to double-check that the addresses are valid and won’t result in spam filters blocking your messages. There are several ways to do this, but one simple way is by using email validation.
Email validation is the process of checking to make sure an address is correct so that you know whether or not someone will be able to receive your message. It’s also known as email verification or email address verification.
While this may seem straightforward,
there are many pitfalls with the most commonly-used methods for verifying email addresses this blog
will we’ll explain everything you need to know about email validation and why it’s so important when sending emails en masse.
What is Email Validation?
Email validation is the process of checking the validity of an email address to determine if it is correct and can receive email. If a person subscribes to your email list but provides an invalid email address, they may never receive your messages.
Therefore, it’s important to verify email addresses before adding them to your list to ensure that they’re correct and that the person who owns that address can receive messages sent from your domain.
The process of email validation can be broken down into two parts: Domain verification and mailbox verification.
*Domain verification confirms that the address is hosted on the same domain as your list sign-up form.
For example, if your list sign-up form is hosted at example.com/list, then you would want to make sure that examples.com is the domain that the email address is hosted on.
Why is email validation important?
Correctly verifying email addresses is critical for avoiding spam filters and successfully sending emails to your subscribers.
If you send an email to an address that is not correct,
it will end up in the spam or junk folder of the recipient’s inbox and they’ll never receive it. This means that you’ll have wasted time and money on sending emails that no one will ever read.
The most common form of email validation is sending a confirmation link to the email address that a person signed up with.
If the address is correct, they’ll receive the message and be able to click the link to confirm their email address.
If a person clicks the confirmation link,
it confirms that they are the owner of the email address and that it is correct.
By doing email validation,
you’re reducing the likelihood of sending messages to incorrect addresses and increasing the number of subscribers who will receive your emails.
How to do email validation
There are several ways to do email validation. Many email validation tools exist that can help you accurately verify email addresses. Some of the most secure and accurate ways to verify email addresses include:
Using Mail Testers to Do Email Validation
A mail tester is a website that lets you type in an email address and then sends a fake message to it. The website will then provide you with information about whether the email address is correct or not.
This can be helpful in determining if an email address is valid, but it doesn’t tell you if the person can actually receive messages from your domain.
Using Blacklists to Do Email Validation
Blacklists are lists of incorrect or fraudulent email addresses and domains.
You can use these blacklists to test the validity of an email address. For example, if you type in the address that a person signed up with on a blacklist, it will tell you that it’s an invalid email address. Unfortunately, blacklists can be inaccurate and result in false positives.
Using Whitelists to Do Email Validation
Whitelists are lists of valid email addresses and domains. You can use these whitelists to test the validity of an email address.
For example, if you type in the address that a person signed up with on a whitelist, it will tell you that it’s a valid email address.
Unfortunately, whitelists can also be inaccurate and result in false positives.
DNS-based Authentication of Mailing Addresses (DMARC)
The Domain-based Message Authentication, Reporting and Conformance (DMARC) protocol helps you protect your domain against email spoofing and other types of email hacking.
It also enables you to specify the action that your server should take when it receives a message from an unrecognized server. There are three DMARC policies: None, Quarantine and Fail. By default, DMARC is set to None, which means that your server will do nothing.
If someone sends an email from an unrecognized server, it will simply be delivered to the inbox. If you want to implement stricter email validation, you can set DMARC to either quarantine or fail.
This means that any email from an unrecognized server will be held in the spam or junk folder of the inbox. Domain validation is the only way to verify if an address is correctly hosted on your domain.

DKIM (DomainKeys Identified Mail)
DomainKeys Identified Mail (DKIM) is a method of validating a domain’s email addresses by using cryptographic authentication. With DKIM, a person sending an email uses a private key and algorithm to generate a message header.
This header is then added to the beginning of the message, which is then sent to the recipient. The recipient’s email service then uses the public key to verify the message header and ensure that it was sent by the correct person.
If everything is validated, the message is delivered to the inbox. If not, the email is held in the spam or junk folder of the inbox.
Unfortunately, DKIM can be misused by spammers who create false “domain keys” and send them to your inbox. If a message comes from an email address that doesn’t match your domain, it will be held in the spam or junk folder of the inbox.
SPF (Sender Policy Framework)
Sender Policy Framework (SPF) is another method of validating a domain’s email addresses by using a DNS record. With SPF, you enter the IP addresses of the servers that are allowed to send emails on your domain.
If a recipient’s email service verifies the message,
it will then use the IP address of the server that sent the message to determine where it came from.
If the IP address is correct, the message will be delivered to the inbox.
when not, it will be held in the spam or junk folder of the inbox. SPF can also be misused by spammers who create false “domain keys” and send them to your inbox.
If a message comes from an email address that doesn’t match your domain,
it will be held in the spam or junk folder of the inbox.
By following these best practices for email validation,
you can ensure that your emails are delivered to the inbox and that your subscribers are receiving the information you want them to receive.
Validating email addresses can also help you avoid sending emails to people who don’t want them. If you send emails to invalid addresses, you might receive complaints from people who don’t want your emails.
Email validation is an important step when sending emails to keep your list clean,
your emails from being marked as spam, and your subscribers are happy.
