There are basically two chief measures to really cleaning your email lists.

The very first is email Validation or Scrubbing (or occasionally cleaning? There are lots of names for this) but basically what you're doing here is remove as much KNOWN crap as you can.

Verification is a lot more expensive part of your general data hygiene procedure, hence email validation eliminates as far as possible until you want to confirm, which saves money and time. I will get into affirmation in my next article. If you want to get the services of email verification api visit

When I say 'Known' crap I suggest that your suppression list (this can be really a listing of known dead mails, spam cubes, honey pots, complainers etc.) and you essentially 'wash' your listing against the suppression list and eliminate any of those terrible emails you have in your listing.

There are lots of actions in email validation (eliminating) your listing of damaging bad mails that you don't wish to email to!

A number of those email scrubbing activities should be:

De-duping – or eliminating duplicates

Role Accounts – eliminating mails such as "data @", "sales @"," webmaster @", etc..

Note: Many folks may want to email to those address since they're calling B2B and these mails address may be who they need contact, but you do not wish to email to the information.

Bad Steak – such as it states, there are well known bad domains out there which are connected with spam cubes or honey pots, which means you'd want to wash from this listing and eliminate any mails you've got with these domain names.
