Choosing well
Does it have an Android app?
Android availability can matter if you want to read and manage email on a Xiaomi, Redmi or POCO phone or tablet. Check the app’s supported platforms; Android support does not by itself indicate Xiaomi- or HyperOS-specific features.
How many email accounts can it handle?
Check the account limit and whether the client offers a unified inbox. These details help you decide whether it fits the number of accounts you want to manage and how you prefer to view their messages.
Can I read email offline?
Compare offline access if you want to read messages without an internet connection. Check whether the client also supports scheduled sending if you want to prepare a message and send it later.

Calendar tools are one of the features compared for these email clients. Check the app’s coverage to see whether its calendar support suits the way you manage email and appointments.

Which platforms does it need to run on?
Check for the platforms you use, such as Android, iOS, web, Windows, macOS or Linux. Platform availability varies by app; examples include BlueMail, Zoho Mail and Apple Mail.
