## How I researched and tested these email apps for Android

Each app ran as my only inbox for at least two days inside those three weeks, on both phones, connected to the same Gmail account with four years of unsorted mail.  
**What I scored:**

- **Notification speed**  
- **One-handed triage**  
- **Pricing**

Three apps came off the list, each for a different reason:
