The Mini-Guide To Check Email Validity (+Tool Types)

Even though good cold emails have a response rate of 40%, it’s essential to ensure that the email addresses are valid. However, verifying an email address’s accuracy can be difficult. As a result, there can be many problems, such as poor sender reputation and low email deliverability. Therefore, to help you out, this mini-guide will provide some tips on how to check email validity to ensure your emails are reaching their intended destinations.

We’ll cover the basics of email validation and discuss some of the most popular methods for verifying email addresses. You’ll also learn about the importance of using tools for email verification. By the end of this guide, you’ll have the knowledge and tools you need to verify emails effectively. 

Why Should You Check If An Email Address Is Valid?

The main reason to check email validity before emailing is to avoid ruining your sender’s reputation. Sender reputation is a score given to your IP address by an email service provider. 

When you send emails to invalid addresses, and if they get bounced, your email service provider will put you under the scanner. A high bounce rate will make your sender score dip, and the email service provider (ESP) can penalize you for your actions and may blacklist you. 

You must be wondering what a bounce means. 

If you send an email and it fails to reach the recipient, it is called email bouncing. 

There can be many reasons for emails to bounce, and they are the following:

1. The email address is non-existent.

2. The recipient’s mailbox is full.

3. The email server is unavailable because of maintenance work or due to a crash.

4. The recipient blocked your email address.

Whatever may be the reason, a high bounce rate can wreck your sender’s reputation, and that can, in turn, negatively affect your email deliverability

Just in case you are not aware, email deliverability refers to the ability to make emails hit the intended recipient’s inbox. 

With a poor sender reputation, your email service provider has a high chance of considering your emails as spam and preventing them from hitting the inboxes of recipients. The emails will go to the spam folder instead of the inbox. When your emails don’t even reach the recipient, your whole email campaign will be a failure. 

Therefore, it is the accuracy of the mailing lists that decides the fate of your email campaign. 

You can avoid all the trouble when you check for the validity of the email addresses on your list. It is a necessity to verify emails as you have to build your domain reputation so that your emails reach their intended destination whenever you run an email campaign from your IP address. Maintaining sender reputation would require effort from your end. 

How Does Email Address Verification Work?

There are different techniques to check the validity of an email address. After the email verification process ends, all the invalid addresses get removed from the list, and you have a clean list for outreach.

Here’s how it works,

1. Email Address Syntax Check

This check removes email addresses that are not formatted correctly. 

2. Domain/MX records check 

In this check, the email address’s DNS entries get verified. When the domain turns out to be invalid, or an MX entry is not there, the email address gets marked as invalid.

3. Role-Based Account Detection

Sending emails to role-based accounts like info@, sales@, careers@ can be detrimental to your email deliverability. The process of role-based account detection can detect such email addresses and flag them.

4. Disposable Email Address Detection 

Disposable or junk collector emails get detected here. These are email addresses created temporarily for sign-up forms asking for a valid email address.

5. Honeypot/Spam Trap Detection

This detects honeypots, spam traps, blacklisted or fake email addresses so that you steer clear of them. 

6. Checking DNSBLs and URI DNSBLs for blacklisting 

Certain IP addresses used for spamming are present in DNS-based blackhole lists (DNSBL) or Real-time Blackhole Lists (RBL). DNSBLs are used to check email addresses and remove malicious emails in the validation process. 

7. Final verification  

In the final verification stage, each email address undergoes SMTP verification. In this stage, the tool checks for the mailbox’s existence by pinging the address without sending an email.  

What Are The Benefits Of Checking Email Address Validity?

The clear-cut fact is that those who check the validity of the email addresses on their lists and remove the ones that are not valid can enjoy several benefits. Learn more about the benefits of email verification. Here’s how email validity check is advantageous,

1. Reduces Bounce Rates

Once you remove the bad addresses from your mailing list or database, you will be sending emails to genuine recipients. As a result, your bounce rates will be lower and your sender reputation will increase. Since there is a higher likelihood that they will reach the inbox, you can generate more leads, increasing your conversion rate. 

2. Improves Sender Reputation And Email Deliverability 

As already mentioned, it is your sender’s reputation that affects email deliverability. Your sender reputation has to be good so that your emails reach recipients. Bounces, spam complaints, and emailing to spam traps can severely harm your sender’s reputation. That is why you must check email address validity to maintain a clean list of contacts.

3. Saves Money

While running email campaigns may look free, there is a cost attached to it. Similarly, there is a cost involved in maintaining databases as well. When you send emails to invalid addresses, and they bounce back, you are wasting your money. Also, by not cleaning your list periodically, you are holding on to bad addresses adding to your storage costs. Regular checking of email addresses will help you save a lot of money. Help get accurate statistics

Before finding out how to check if an email exists, you should know when to verify them. Here is when you should consider validating your list of email addresses,

1. You have added new contacts to your mailing list.

2. It has been more than one month since the last check.

3. Your bounce rate is on the higher side (ideally, it should be under 5%).

4. The open rates are on the lower side.

Then there is the double typing method whereby the user must enter their email address twice while registering on online forms. It helps in preventing typos and syntax errors.

These tools make the task of verifying email addresses more effortless and faster. It is worth the money you invest in purchasing them.

Email verification tools require you to upload your list of email addresses, and they would deliver the report marking the ones that are risky and undeliverable. You can then remove the invalid ones from the list and proceed with your email campaign.

Most tools are easy to integrate with cold email software and reduce your work of uploading the list of contacts twice. 

Tools that check if an email is valid to carry out three types of verification, and they are the following:

2. Domain check

This email search method involves checking the domain and the recipient’s email address to see if it is working or not.

3. Email Ping

The tool sends a message to the recipient’s server to verify email addresses. It helps determine whether the email address exists on the server or not and if it is currently in use.

Types Of Email Verification Tools

While all the email verification tools aim at removing invalid addresses from the mailing list, there are three main types of verification tools:

1. Bulk verification tools

Bulk verification tools require you to upload a list of email addresses, most often in the form of a .csv file. The tool then checks all the addresses in one go and marks the addresses as valid, invalid, and risky. Bulk verification tools are suitable for those who have a vast database of email addresses. 

2. Real-time verification tools

3. Ongoing/Automated verification tools

Automated verification tools remind when email list cleaning is required or automatically scan your database of email addresses periodically and remove invalid and risky addresses.

What To Look For When Selecting An Email Verification Tool?

5. Integration
