Your mail stays on the phone.

One account is enough. Several, when you need them.

With one account, the inbox is that one. When you have more, All inboxes puts the mail in a single list, and each row says which account it came from. The same address cannot be added twice.

A second account needs cMail multi. Extra accounts stay in the list, frozen, and nothing is deleted. When cMail multi is active, they sync again. On each account you see the type, the address and the last sync, and you can sync now. On IMAP you choose how many messages to fetch and how often.

The inbox

You open it and see what is unread, who it is from, and what time it arrived. Each row shows the sender, the subject, a short preview and the time. Unread mail has a bar. If there is an attachment, the clip sits beside the time. On All inboxes, the row also shows the account. Search sits above the list, and a blank search shows the whole inbox again.

You sort by date, newest or oldest, by sender or by subject. You can put unread mail first. You can group conversations. If you do not, each message is its own row, and pinned mail stays at the top.

Swipe right to mark read or unread. Swipe left and the message goes to Deleted, and you can undo. A tap opens the message. A long press opens the actions: reply, reply all, forward, forward as an attachment, archive, pin, or select more. With several selected, the action applies to all of them. Pull the list down to refresh.

Reading a message

The message fits the screen, and the new text stays in front. The header stays put. Only the body scrolls. HTML fits the width of the screen, and pictures fit the space in the message instead of spilling past it. Remote pictures load. Quoted text sits behind a button, so the message does not open on a chain of earlier replies.

If the message is from a list, Unsubscribe appears, and the app uses the request in the header. Attachments are listed on the message and download to Downloads. You can save the whole email, with its attachments, as an .eml file: you choose the folder, Downloads by default, and the name. An .eml file on the phone opens in cMail.

On the open message you can star, save, archive, delete, reply, reply all and forward. Text size follows the volume keys, in the list and in the message.

Writing

You reply as yourself, or as an alias, with the right signature. For work, that matters. From and To stay visible. Cc and Bcc appear when you ask for them. The body is an HTML editor, with formatting. The signature can be plain text or HTML, and you choose whether it goes on a new message, on a reply, or on both.

You can send from an alias, or from another address, on cMail and on cMail multi. S/MIME: you import a PKCS#12 certificate, sign what you send, and encrypt to a recipient certificate you have imported. Incoming mail can be decrypted and the signature checked. That is S/MIME, mail signed and encrypted with those certificates.

Folders, move and copy

The mail does not sit in one long list. Each account has Inbox, Sent, Drafts, Deleted, Spam and Archive, plus whatever folders the server has. Opening a folder syncs it. Move and copy work to another folder, and also to another account.

Pin puts the message at the top of the list. Star marks it, and a filter can add or remove the star. Blocking a sender takes those messages out of the inbox. Removing the account takes it off this phone, with the local mail, drafts and cache. The mailbox on the server stays.

Filters and workflows

New mail can sort itself, with rules you set. A filter has an optional name and an on/off switch. You add only the conditions you want: from, to, subject, text, attachment, one account or all of them, and a folder. Empty fields are ignored. The conditions all apply together. The actions are move, mark read or unread, star or unstar, a priority notice, or move to Deleted. None of them is required. Moving to Deleted asks you to confirm when you save the rule.

Filters run on new mail, during sync. You can also apply them now to the latest 200 messages in scope. A workflow is an ordered list of filters. You can stop at the first one that matches, or let the later ones run. The rules stay in the database on the phone. cMail does not send them anywhere.

Notices and the home screen

You know when mail arrives, and what you mark as priority can notify you on its own. The first load of an account stays quiet. After that, new inbox mail notifies you. While the app is open, the notice is silent. In the background, it makes a sound. There is the normal channel and a priority channel, which a filter can use. Tapping the notice opens that message. A notice stays until you open it.

The home screen has two widgets: the unread count, and the message list. After you place a widget, you choose the account and the folder. Both follow the light theme and the dark theme.

Theme, language and colour

The theme is light or dark. The language is Portuguese or English. Each account has a colour, on the avatars and in the list, from ready-made colours or one of your own. The unread bar keeps the app colour.

Backup

You take the accounts with you. A manual backup is a file encrypted with a passphrase you choose. Import brings the settings back and does not delete accounts already on the phone. If an address is already there, that account and its messages are left out of that import.

Scheduled backup runs every day, to a folder you choose, or to your own Google Drive if you connect it. It takes the accounts, the settings and the cached mail. Drafts, Spam and Deleted are left out. The file is yours. On Drive it uses your Google account's space. CodeSharper does not keep the backup, and Drive is used only after you connect it.
