Are you experiencing a situation where your email list is expanding but the open and click-through rates are still low? If so, it is possible that your list needs to be cleaned up using email verification.
Email verification tools are the perfect solution that scans your email list and removes any invalid or harmful emails by performing various checks. As a result, you will observe an increase in the deliverability rate and safeguard your email server’s reputation.
We have listed 12 email verification tools and self-contained methods that can be used to eliminate useless email addresses from your list.
What is email verification?
If you’re engaging in cold outreach, email verification is an important process that you shouldn’t overlook. It involves confirming the validity and accuracy of an email address, which is crucial for ensuring that the email addresses you’re targeting are active and valid.
If you send emails to email addresses that are not valid or inactive, it can be a waste of your resources and time. Moreover, it can harm your email sender’s reputation and lessen the efficiency of your cold email or email marketing campaigns. This is why email verification is extremely significant.
There are two main ways to perform email verification.
The first is manual verification, which involves sending a confirmation email to the email address and waiting for a response.
The second is automated email verification services, which use various methods such as domain validation, SMTP (Simple Mail Transfer Protocol) checks, and mailbox checks to verify email addresses.
Automated email verification services are usually more efficient and accurate than manual verification, as they use advanced algorithms to identify and verify email addresses. Some email verification services can also check email addresses against databases to ensure their validity.
What happens if you don’t use email verification for cold outreach campaigns?
If you’re planning on conducting a cold email outreach campaign, it’s crucial to perform an email verification check. Skipping this step could lead to serious problems down the line, such as high bounce rates, low deliverability rates, and damage to your sender’s reputation.
Here are a few examples of what can happen if you don’t verify your email addresses before sending:
- High bounce rates: If you send emails to invalid or inactive email addresses, you’ll end up with a high number of bounced emails. This can hurt your email deliverability and sender reputation because email providers see high bounce rates as a sign that you might be sending spam or unwanted emails.
- Damaged sender reputation: Your sender reputation is a measure of how trustworthy and legitimate your emails are. If you’re sending emails to invalid or inactive email addresses, your sender reputation can be damaged, since this is a sign that you aren’t taking proper care of your email list.
- Emails going to spam: If your sender reputation is damaged, or you’re sending emails to addresses that have been marked as spam in the past, your emails might end up in recipients’ spam folders instead of their inboxes. This can seriously hurt the visibility and effectiveness of your email outreach campaign.
- Deliverability issues: If you’re sending emails to a lot of invalid or inactive email addresses, email providers might start to flag your emails as spam. This can cause a lower open rate, click-through rate, and overall effectiveness of your cold email campaigns.
Email verification vs. email validation
Initially, these words had the same meaning. However, a slight difference has emerged between them. While the two terms are still similar, the distinction between them is subtle but noticeable.
Email validation is the process of checking an email address for accuracy and validity. This includes verifying the syntax, domain, and mailbox of the email address to ensure it is deliverable and can receive emails.
For example, a mistyped email address such as “[email protected]” would be caught during the email validation process, as “gamil.com” is an invalid domain.
Most email verification services also include email validation as part of their process to ensure that the email address is accurate, active, and valid. This is because email validation is a crucial step in ensuring that the email address is not only active but also belongs to a legitimate user and has not been marked as fraudulent or spam in the past.

How do email verifiers work?
Verifying the accuracy of your email list is for maintaining a positive sender reputation, so it’s worth learning how to check email addresses for typos and syntax errors, the existence and activity of the email address, as well as their safety and deliverability.
When choosing an email verifier, it’s important to consider the type of verification offered. Some verifiers may only offer one type of verification, while others may offer a combination of different verification methods.
Here is an explanation of how email verification works, which may be helpful:
Syntax check
- To ensure the accuracy of email addresses, a thorough check is conducted on the local part, the at-symbol (@), and the domain name with a dot-symbol (.).
- The local part cannot exceed 64 characters, and it must have dots (.) and symbols (@) placed correctly.
- Special characters (? “# $ % & ` * + _- . / | ^ {}) are allowed only in the local part, but not at the beginning or end.
- Checks for common errors like periods (.) at the beginning or end of the email address, commas (,) instead of periods (.), semi-colons (;), or apostrophes (‘) instead of the at-sign (@).
- Additionally, it verifies for spaces or blank areas ( ) in the middle or at the end of the address, double periods (..) in the local part or domain name, missing “.com” or period (.) in the address, or any misplaced signs (@).
- Email verifiers help detect spam traps and invalid email addresses before they cause any trouble with ISPs or ESPs.
Domain existence checks
When checking for the validity of an email address, email verification services also ensure that the domain name is accurate and is functioning.
This means that if someone enters an email address like [email protected], but the domain under domain.com is not registered, an email verifier would flag it as invalid. These services are here to help ensure that your emails are reaching their intended recipients.
MX record check
MX records, also known as Mail exchanger records, play a crucial role in verifying the validity of an email address. It goes beyond the basic email verifier that only checks the email format and characters, by verifying if the domain name exists and is configured with email DNS settings.
Catch-all domain checks
If you have a catch-all server, it means that all emails sent to your domain will be accepted, even if there is no specific mailbox for them. To check if an email is part of a whole domain, you can use an email verifier that is reliable and trustworthy.
It’s important to note that if you receive a verified email as a catch-all, you’ll need to decide whether you want to send emails to it or remove it from your list completely. Using a verified catch-all email address when sending emails can cause risks, such as higher bounce rates and being marked as spam. This can harm your email deliverability and sender reputation, so it’s best to be cautious.
SMTP authentication
The last and crucial stage of the process is to validate the individual mailbox. Email verification services utilize the SMTP protocol to examine whether the recipient’s domain has a legitimate MX record. If it does, it then verifies the existence of the username and proceeds accordingly.

The ideal validation service should cater to all or most of your requirements and possess the highest precision level in recognizing invalid, undeliverable, and spam email addresses. To ensure the service is reliable, it must verify correct syntax, catch-all servers, domain authentication, and SMTP authentication at a minimum.
Additionally, some other attributes you might want to contemplate when selecting a provider are:
- Take into account the speed at which the service can check your mailing list and provide results.
- Consider the options available for uploading your mailing list, including the choice between verifying only a few addresses or doing a bulk verification, as well as whether you prefer a software or cloud-based tool.
- Ensure that the provider follows standard data protection practices and is GDPR compliant to keep your mailing list data private and secure.
- Consider the price of the service and whether it fits your budget. Some email verification services offer free or trial plans for those starting with email marketing, while subscription or pay-as-you-go plans may be better suited for larger or ongoing campaigns.

Can I verify emails myself?
You have already read about some in the previous section, where we described the workflow of verifiers, revealing their types (domain, DNS, SMTP verification).
Nevertheless, we have incorporated some straightforward approaches to authenticate your email accounts in this segment. Certain techniques demand expertise in email technology.
Ping the server
To verify email addresses without actually sending emails, you can use a technical process called “pinging the server”. This method requires a tool like PuTTY for Telnet on Windows or the iTerm app on Mac. Here’s how to do it:
1. Enable Telnet on your Windows system.
2. Open the command prompt and enter the nslookup command: nslookup –type=mx domain.com. This will reveal multiple MX records associated with the domain, so choose the one with the lowest preference number.
3. Connect to the telnet server by typing: telnet {mail server address} 25.
4. To initiate a handshake with the server, type: HELO.
5. Next, provide your identity by entering a random email address as follows: mail from: {random email address}.
6. Then, add the email address you want to verify by typing: rcpt to: {email address to verify}.
7. If the server responds with an OK message, the email address is valid.
This is a helpful and friendly way to verify email addresses using the ping the server method.
Send an email from a different account
If you want to ensure your email gets delivered to a specific account, it’s best not to use your primary email address, as it can be risky. Instead, it’s recommended to set up a dummy email account to test it out. Moreover, manually removing the bounced accounts from your email list can be done, but it’s a bit of a hassle since it involves repeating tasks twice.
Use a free email verification tool
Several free online tools can also help with email verification, such as Verify Email Address, Quick Email Verification, and Hunter Email Verifier. These tools typically use algorithms and databases to check email addresses and provide a status report showing whether the email is valid, risky, or invalid.
However, keep in mind that manual verification can be time-consuming and may not be as accurate as using a specialized email verification service. In addition, free tools may have limitations in terms of the number of email addresses that can be verified per day, and some may not provide advanced features such as spam trap detection or disposable email detection.
Wrapping up
In this article, we have outlined the top email verification tools that will help you easily remove incorrect and invalid email addresses from your marketing lists.
This will make it easier for you to achieve a positive return on investment (ROI) on your campaigns. It is recommended that you use these tools frequently to maintain the best possible deliverability of your emails.
