Mailbox Comments

Where is Spark (and Polymail) as alternatives?

Comment by pacorob
about Mailbox Feb 2016

Spark and Polymail should definitely also be added to the list of alternatives for Mailbox.

My favorite is Spark and after that Airmail. Outlook is also ok but lacks a great search feature. You can only search in e-mail of 2 months old.
