Best Email List Cleaning & Verification Services

Are you looking for a service to get your email list cleaned? If so, you have landed on the correct page! Having a clean email list is utmost importance for the success of your email campaign. This will greatly uplift your email inbox rates which will give you more visibility, click throughs and eventually conversions. While most marketers believe that the size of the email list matters, let me tell you that it’s not the size but the quality of the email list which matters if you want high inbox deliverability rates. Sending email campaigns to a bad email list can get you into serious trouble getting your IP address, domain and brand blacklisted. And, the worst part is, once you get blacklisted, it is almost impossible to repair your reputation. So, it is always best to send email campaigns to a cleaned email list which has low bounce rates, good open rates, no spam traps and preferably an opt-in email list.

So, what exactly is an Email List Cleaning Service?

The email list cleaning service is basically a tool which cleans your email list and removes invalid, expired and spam trap email addresses. The email list cleaning tool will check whether the email address is in fact exists and whether emails can be delivered to it or not.

So, how do the Email List Cleaning Services work?

Each email list cleaning service available out there has their own way of cleaning the email list. But the main aim of those email list cleaning tools is to remove invalid, expired and spam tram email addresses.

Below is the general process most email list cleaning services use to get your email list cleaned:

Checking Syntax –  There can be quite a few email addresses which are misspelt. For example, an email address which is could be misspelt as or an email address which is could be misspelt as

Verifying and classifying of role based email addresses – Your email list most probably would contain email addresses like info@, support@, sales@ and other role based email addresses. The email list cleaning service will check whether they still exist in the first place. If they do not exist, the will mark that email address as not working. Most email list cleaning services will also classify your email list pointing out whether the particular email address is role based or not.

Get rid of disposable email addresses – The email list cleaning service will check if the email address is a disposable one. A disposable email address is an email address which is used by people for a one time use. This happens when the person who registers on your website wants to use your service but doesn’t want to give up his / her real email address. The email list cleaning service identifies and removes such email addresses.

Validating MX records – This process checks the MX records of a domain. If the domain does not contain valid MX records, these email addresses are marked as non-working email addresses.

Detect spam traps – This is one of the most important features which you could use. Please note, not all email list cleaning services provide this feature. Before you use any email list cleaning service, make sure that they provide this feature. A spam trap is an email address used by ISPS to lure in spammers. If you send an email to a spam trap, the ISP which uses that spam trap to lure in spammers will black list your domain and IP.

In addition to the steps mentioned above, there will be other processes like sending SMTP pings to each email address to confirm whether the email address in-fact exists. Once the process is complete, the email list cleaning service will let you download your cleaned email list. Most providers also let you download bad emails including the reason why it was classified as bad for you to get a better idea as to why the email address in question is marked as bad.

Advantages of getting your email list cleaned

  • Remove invalid email addresses so that you have a low bounce rate
  • You will have a good sender reputation
  • Minimum or no spam complaints
  • If you have a good sender reputation, it will improve your overall domain reputation
  • Higher open rates which derive higher click though rates
  • Good open and click though rates improves inbox placements
  • Reduce your cost for sending emails. Because you won’t have to send to non-existing email addresses. Sending email campaigns only to working email addresses requires lesser resources.

There are many more advantages of getting your email list cleaned but I have pointed out the ones which come to mind while writing this article.
