extract email address

Remove duplicates emails, URLs, phone numbers

ExtractingEmailAddress removes automatically duplicates.

Email addresses

However, some people may have two different form of email address. john.bloggs@supercompany.com and j.bloggs@supercompany.com for example.
In that case, you can sort out by company (priority 1.), then by family name (priority 2.). It will be easier for you to strip out manually this kind of duplicates.

To do that,

• click > sort by > and drag 'company' in the top position, then drag 'family name' just below
• click 'extract'
• go through the email list result manually

Phone Numbers

Also that some phone numbers may be the same for a human, but not for your computer:
+374 9 1234567 would be the same than +374 (9) 1234567 for a human, but would not be removed as duplicated from your computer. You could sort this manually.
