FREE Email verifiers.

We have heard and seen so many email verifiers claiming to be the best and free, but honestly, they have all proven to be false. For example, you Google and come across a link claiming FREE bulk email verification. When you go to that site, there is a catch. They are not 100% free, or they are not free at all. It was just a well written content to fool search engines into bringing traffic to the site. You are given some credits to test and then asked to pay for further testing. Then you will come across the sites claiming to be free, but they check the syntax of your emails and run mx check. People with basic knowledge of email verification will know this is not a real email checker service. They are doing a part of the email verification, but not real email verification has other necessary steps. We will discuss them in detail below.

Syntax and Formatting

That is the most basic step when verifying emails. Ensuring the data does not have emails with typos are not following the email standards. For example, an email is not missing the @ symbol, or no domain is missing inside the email. 

This step helps in removing any invalid emails and saves time. You remove the emails that have typos or are incorrect. 

Domain Verification

Domain verification is the next layer, where the email is checked by the domain to see if the domain is valid and exists. This process ensures the domain used in email is valid and the domain is carrying a mailbox, which is an MX check. 

MX check ensures that the targeted domain has a mailbox setup. When people purchase a new domain, it does not come with the mailbox. You have to connect your domain with some hosting. Domains with no MX records mean the emails are not configured. 

BlackList Check

This step is also important; many companies ignore this and do not check if the targeted domain is blacklisted. Why would you like to email a domain that has been blacklisted? Using some services, you can check if the domain is blacklisted or not. 

Sending emails to a blacklisted domain can harm your domain reputation, so it's better to avoid sending emails. 

SMTP Email Verifier

That is the most important step, and this final step in the process tells us whether the targeted email is valid. SMTP verification is the process of talking to the email host and verifying if the email we are checking is actually the right one. Once the host accepts an SMTP handshake, we ask if the targeted email is valid. 

Most email hosts do not allow multiple SMTP handshakes, and they block incoming requests. That is where most service providers need help to check the validity of emails. 


Email Verification and its results. 

When an email is verified, it's important to understand the labels used to help you with your email marketing. Even though the email looks valid, it is valid. It can lead you to problems. We will discuss all the possible results to classify email results further. 

Valid Emails

As the name suggests, these are valid emails; you can send emails to these domains. Remember that an email that shows valid today may not be valid after 30 days. Data shows that over 25% of emails die out after 30 days. We will share some case studies to back the claim. 

Let's say you work for a business and use that email to create an account on a website to use their service. You get an offer or an opportunity from a different business. So you decide to move on. In most cases, your email is either deleted or forwarded to the generic mailbox, which is usually never monitored. Let's say the tech decided to delete the email as it cost the company, and there is no longer any use for the email. Now, whenever that company you signed up with sends an email, it gets a bounce back. Telling them email does not exist. So it's very important to keep the email list clean and check it every 45 days, as advised by experts. 

Invalid Emails

As suggested by the name, it is very simple: the emails are invalid, and you should not send emails to these email accounts. Sending them emails on invalid email accounts creates many issues and compound problems. It may not seem like a big issue from the face, but it's a big issue. 

When you send emails to invalid emails, the email service providers grade your business/domain if you are sending clean emails. The first flag to catch spammers is hardbounce. Since spammers do not know the emails in their database are real. They send emails to anyone and everyone. Once you cross the threshold of hard bounce, serious issues will occur. 

  1. You will notice your emails are not getting open rate
  2. Your ROI goes down since less open means less business
  3. Your emails land in spam folders 
  4. Some providers will block you completely
  5. Your regular emails with your other customers will be affected
  6. Domain getting blacklisted.


Catchall Emails

People use different terms for this label; catchall emails are technically valid, but not sometimes. We will explain in detail how catchall or accept all emails work. So the name suggests catchall. Some domains use these settings on the server end to accept any incoming email to their domain; this is another way to fight spam. So, let us say you want to email alex@bulkmailverifier.org, but you typed alexx@bulkmailverifier.org, bulkmailverifier.org uses catchall settings. Since you have the domain name spelled correctly, your email will not be bounced back. Your email will get delivered, but it will not be delivered to alex@bulkmailverifier.org. It will go into a special folder set up to catch incoming spam. These folders are not monitored. 

Sending emails to the catchall domain is only recommended if you have spoken to the person. 

Rolebased Emails

Role based emails are emails that are mostly linked with either a role or a department. For example, sales, support, admin, care, and info. As you can see, the emails are suggesting a role behind it. When you send emails to these particular emails, they land inside a shared inbox. 

You sent an email to sales @ abc.com, and chances are, it will never get replied to. Yes, it would be read since the sales department monitors it, but your promotional email is useful for them. Their inbox role is to feed them sales-related info, generally related to leads. 

Unknown Emails.

Unknown emails are tricky; these emails look valid, but there is a 50% chance of being invalid. They will pass the initial steps but not the final steps of SMTP verification, which means that the host email server did not accept the handshake or refused to accept the SMTP handshake. So, it still needs to be 100% confirmed if the email is valid. That is why the emails are marked as unknown. We do not recommend sending emails to unknown domains unless you have been communicating with a particular email in the past.
