Gmails new tabbed inbox feature automatically categories and sorts incoming mail using several different filters. FATdrop messages will be sorted into either “Updates” or “Promotions” (depending on which tabs you have activated) although you may wish for promos to appear in your “Primary” tab
The Primary tab by default is for person to person conversation, however it is possible to update this so promos from FATdrop will appear there.
Firstly find a promo from FATdrop, right click on it, then select “Move to tab” / “Primary”.
After doing so you will be given the option “do this for future messages from firstname.lastname@example.org”
Click “Yes” and now in future promos from FATdrop will appear in your “Primary” tab.
