Support for many other email services via standard Internet email protocols: IMAP, POP3, SMTP. This covers Exchange, too, provided that the server has IMAP/SMTP enabled (no ActiveSync support, EWS is planned).

Push mail (IMAP IDLE, instant incoming email delivery) for those servers that support it (Gmail and more). Plays well with other email apps that you may be using to access your IMAP mailbox. Uses existing folder structure, can synchronize drafts, sent, and deleted messages.

Can save attachments on the memory card, can attach any file type (a file manager is required for picking, my favorites are ES Explorer and Solid Explorer). Learn more.
