In this first step the email verifiers checks the spelling errors. Some of the criteria’s that the tool looks into are commas, spaces, @ wrongly placed and domains etc. For example if an email ID that is Sonam@[email protected] this can be easily retrieved and removed once the email verifiers bring this to you.
  • Step 2: The second step is all about checking the domains. The verifiers check the domain of the email ID and if the domain is not there or is not working then this email are regarded as invalid. There are many such email IDs that can come up in an email list and it is very important to make sure these are removed.

Why is it necessary to verify emails?

There are many reasons why emails should be verified from time to time.  When these IDs are invalid then there is no use of sending emails to those Ids and most of the time and energy of the sales team would be wasted in these invalid ids. There are several reasons that can actually cause an email change or invalid email; here are some of the reasons.

Change of email ID – This is one of the most common reason of email id getting invalid. There are times when a person wants to change the domain because of various reasons. In such cases the previous Id gets invalid. Although the email Id is invalid, the id will still be active and in such cases although the email will be in the inbox but will remain unread. That is why it is important to separate such email Ids out of your email list.

Change of email Id with the same provider – This is another classical example of change of email Id within the same provider. The user might want to change the email ID and opt for a more suitable one within the same provider. For example if, [email protected] wants to change her Id to [email protected] then the previous Id will stay active but the emails will be unread.

Change of position in the company – In most of the companies the email Ids are different in different levels. In the higher levels, they all have the same ones. In such cases when a person moves from one level to another level than the previous email Id becomes invalid. In such cases your email will get bounce and hence it is important that you remove the previous one and put the latest one for that particular person.

Change of Jobs – In most of the cases when a person changes his or her job to some other employer, in such cases new email Ids are given to that person. And when you do no change the email list, all your important mails will be on the previous Id of that person. In some companies there email Ids are replaced by new employees. In such cases your email will be received by wrong person and that is the last thing that you want.

Dead Domain – In most of the cases, when a company is out of the business the domain becomes inactive. In such cases there is no point in mailing to these email ids. Email verifiers will retrieve these ids and present it to you, which you can remove from your email list.

Inactive public email provider – In many cases the email providers gets out of the business and hence is dead. In such cases the email Ids becomes invalid or useless. In such cases, it is important that you know about these email ids which you can remove from the list.

Reasons to verify emails

Verifying email Ids is very much important and from time to time it is important that you verify the email ids of your email list. There are times when your Id might lead you to some untrusted email Ids which can reduce your email deliverability and also reduce your reputation in the business.

When your emails are getting into invalid ids all the time, then your reputation decreases and you might be blacklisted for that.
