Features users are literally asking for in their reviews, ranked by demand.

#1: Ability to block senders

High Demand

"Blocking unwanted senders is the easiest way to limit spam; shouldn’t be a paid feature."

#2: Better spam filtering

High Demand

#3: Unified inbox for multiple email accounts

Medium Demand
"Managing multiple accounts is cumbersome; need a unified inbox."
"Switching back and forth between accounts is very tedious."

#4: Offline email access

Medium Demand

#5: Customizable notification sounds

Low Demand
