Dedupe Files

Removing duplicates from a file is useful anytime.  Duplicate removal is step #1 in maintaining a clean list.  Deduping has several facets to it, in that it can be used to removal duplicate email addresses as well as duplicate domains, for those who collect lists of businesses and only want to email a business once to one of the collected addresses.  Since many businesses often have several departments or contact email ( Example : support@emailspyder.com and billing@emailspyder.com ) removing duplicate domains can often be needed.  NOTE : MAKE SURE YOU BACK UP YOUR LISTS BEFORE USING THIS FUNCTION IF NOT MERGING SEVERAL LISTS TOGETHER, AS THE LISTS WILL BE OVERWRITTEN BY THE RESULTANT DEDUPED LISTS.

Using Dedupe Lists :

1. Click the ' Browse... ' button next to the input file list to open a standard open-file-window.
2. Select the files you wish to dedupe.  Select multiple files by holding down the control key while clicking.  Click the OK button when finished.
3. Click the Apply Settings button to complete the setup of this job.  Any missing items will be detailed in the text box at the bottom of the window.
