People often use email cleaning, email scrubbing, and email verification as if they mean the exact same thing. In day-to-day marketing conversation they overlap, but the terms still point to slightly different ideas.
Email verification
Verification is the most specific term. It focuses on whether an address looks valid enough to use.
That usually includes checks such as:
- syntax
- domain and MX availability
- typo signals
- disposable-domain detection
The result is usually a status on each address.
Email scrubbing
Scrubbing usually means a broader cleanup of the file itself. That can include:
- duplicate removal
- formatting cleanup
- basic typo correction
- normalization of messy fields
It is more about tidying data than making strategic send decisions.
Email cleaning
Cleaning is the broadest term. It often includes verification plus the judgment call about what to send, what to fix, what to suppress, and what to remove.
In practice, when most teams say "we need to clean the list," they mean:
- identify the obviously bad addresses
- separate the questionable ones
- export a cleaner file for the next campaign
That is the problem MailCull is designed to help with.
