Email Validation: Verify and Validate Email Addresses

The accelerating acceptance and status of email marketing around the world have given rise to a market segment, known as the market for list validation. In case you all are trying your best to concentrate on an email campaign for your brand, the top priority should be the auxiliary tool to be the best and win your target audience’s trust and this is only possible when you are using a bulk email checker. Irrespective of which sector you are or what infrastructure you refer to every sector these days depends on emails to communicate and send across messages to their target audiences. Looking at the demand that is intensified in the market and the dynamic behavior of the market, there is only one reliable marketing technique that helps us reach out to our potential audience and also to them who we know want to know from your brand. These all happen seamlessly provided your email list is verified. Reaching out to your client base requires email filtering or cleaning software that will do the job required and at the same time keep your databank updated and secured to be used. Once you can attract traffic-you will see an upsurge in your senders score as it will show an upward climb. Let us understand how to comb the market list and filter the data before it is too late. 

Before we hit the next section of this blog to understand the Importance of email validation, we must first clearly understand what Email-validation is and how is it dissimilar when we say email verification?

The online answer to the question “Difference between email-verification and Email-Validation” is quite confusing as most of the write-ups define it interchangeably and citing one’s definition. We thought of bringing to you a simple yet informative definition of the two. 

Verification of email or simply [Email-verification]

Is a step-by-step procedure of inspecting if the email address exists or is active. The definition of an email that is ‘valid’ is one which receives emails from others. There is more than one step to verify an email address and the most common ones are syntax or [MX record check] domains and more.

Validation of email or [Email-Validation]

This is the concluding outcome of the Verification process mentioned above. The final verdict of a valid email is obtained only after checking and undergoing the email verification process.

“The most general procedure to verify and validate an email address is to shoot a ‘test email. If your mail bounces–you need not make any further attempt to send another mail–you can simply tag it as “email does not exist. The best part is that you need not send a test email to verify every mail, HandySends has a simpler way to help you and check and verify if an email address is valid without even bothering to send a test mail”

Importance of validating an email address

Planning to launch an email campaign without the pain of verifying every email address. We have systematic processes wherein all recipients will receive an email in their mailbox without worrying about the bounce back–the key factor here is the higher the bounce, the sender’s reputation is at stake, and simultaneously, the deliverability decreases. If one continues to send emails to invalid email addresses–they are simply landing on the spam folder which is not a healthy practice in the long run. It is thus important to understand the best practices whilst adhering to systematic email sending methodologies and safeguarding the sender’s repute…  

“Email Campaigns success depends on the success of email delivery”

How do we know when is the time to validate an email address?

The most important key to email validation is to understand the fact that it is not a periodic activity. Research and survey analysis recommends conducting email validation only if:

  • You have added a new addressee 
  • Your open score is much less than the last few trends
  • You conducted your last email validation over 30 days 
  • The % of your emails bouncing back is more than 2.2%

Identify the process to validate emails

What does a systematic email validation process consist of? What is the process of an email verifier and how does it operate?

One can opt for several technical gradations to understand the process of an email verifier and how does it operate. It is simply an idea for any layman to test emails and check their verification based on the algorithms the system developer codes it with. We have a detailed email verification process that guarantees the highest accurate outputs.

  • Most importantly validating of the Syntax 
  • Verify and filter throwaway emails
  • Re-verify the common typos
  • MX records
  • Check the DNS 
  • Ping mailbox 

How is a validation of Syntax done?

Assume your email address is [email protected]. One can see it consists of a local (test) and domain ( parts.

Your local portion can comprise:

  1. Characters which are a mix of the alphabet & numerical– A to Z (both upper and lower case) and 0 to 9 
  2. Pattern able typescripts – #$ %&’*+-/=?^_`{|} ~ 
  3. One single (.) dot (the local part cannot start and end with a dot, and you can’t use the dot consecutively like [email protected]). 

Additionally, it also evaluates for simple email address arrangement [syntax] errors:

  • Dots (. ) whether it is being used at the finish of the email address or the start 
  • Commas (,) have we used a comma instead of a full stop or dot (.)
  • The use of Colon ( : ) or double apostrophe ( “ ) in place of ( @ )
  • Blank Spaces or missed areas (   ) somewhere while mentioning the address
  • Two dots ( .. ) in place of single
  • No mention of “.com” or dot  ( . ) in the email-address
  • Misuse of using signs (@)

Verify and filter throwaway emails:

A filter throwaway email address is just a provisional address that is effective for some time. What is important here is to ensure you have cleaned all your email of any throwaway emails which are usually generated by Nada, Mailinator, and comparable services. If you wish you can use the third-party API, such as InboxHit. These can unfailingly identify throwaway email addresses from your list. Also, this helps you search domain names used for provisional email addresses and use them. 

Re-verify common typos: 

Mistakes, spelling errors, and typos are additional features one must focus on while validating email addresses. For instance, your email list might comprise [email protected] instead of [email protected]. These might look simple but can be implemented in your RegEx rule as well.

Check the DNS: 

When we sat to check the DNS, what it means is a simplified process of demanding a DNS report from a DNS server. In your case, you’re concerned about the MX records. The DNS entry here specifies the email server for accommodating emails for the domain name. Here is an example of a DNS lookup for 

  • Check the following on your console


  • You’ll see several MX records for domain “” and their priority values:
Email Validation

Pick the email server with the top priority. The least is the preference value, the highest the priority. In your case, this is “” You’ll need this input for the next step of the checklist.

MX Records 

In unpretentious expressions, an MX record simply alerts the server which is responsible for receiving mails for a definite domain. It’s an enhanced solution for recognizing throwaway emails. This aspect verifies if the email exchange access is enlisted in the email address and is genuine, listed, and holds a domain name, which can be retrieved as and when one is online.

The MX record also checks all inevitable steps in an email verification procedure. Although there are add-on technical features concerning this process, nonetheless the idea is to deliver accurate outcomes; an email-verifier has to predominantly depend on an MX record check for its validation processes.

Ping Mailbox:

Once the DNS lookup is done, the validation of your email address is done via SMTP connectivity. All you need is to connect to the SMTP server and then request if this email address exists. Should you see the server replying with (250 OK) the email address provided or being verified is valid? In case the server sends us a reply (550-5.1.1 User Unknown) this email address does not exist.

    First off I want to say excellent blog! I had a
    quick question that I’d like to ask if you do not mind.
    I was curious to know how you center yourself and
    clear your thoughts prior to writing. I’ve had difficulty clearing my mind in getting
    my ideas out. I do enjoy writing but it just seems like
    the first 10 to 15 minutes tend to be lost just trying to figure out how to begin. Any suggestions or hints?
