5. An animated "Sent!" overlay appears with a spring scale/fade animation, auto-dismissing after 1.5s.

Send-as aliases

If your account has multiple send-as addresses configured (in Gmail or Outlook settings), a "From" field with a dropdown arrow appears at the top of the compose screen. Tap to pick which address to send from.

Attachments

• Adding: Tap the attach icon (paperclip) in the bottom bar → system file picker → any MIME type.
• Display: Shown as a horizontal scrollable row of preview cards. Images show a thumbnail; other files show an icon + filename + size.
• Removing: Tap the close button on any attachment preview.
• Compatibility: Attachments are base64-encoded and sent as multipart MIME.

Viewing attachments

Attachments in received emails are shown in two sections: images as inline thumbnails (max 280dp height), and files in a responsive grid with extension badge, filename, and size. MonoMail includes an in-app viewer for images (pinch-to-zoom), PDFs (PdfRenderer), and videos (Media3 ExoPlayer). Other file types show file info with an "Open with..." button.

Schedule send

1. Tap the schedule icon (clock) in the bottom bar.
2. Pick a date (DatePicker dialog) and then a time (24-hour TimePicker).
3. The email is saved to the local database and sent automatically at the scheduled time.
4. View/edit/cancel scheduled messages by tapping the calendar badge in the inbox search bar.

Undo send

After sending, an undo bar appears in the inbox with a live countdown (configurable: 5s, 10s, 20s, or 30s). Tap Undo to cancel the send. Configure in Settings → Compose → Undo Send.

PGP encryption and signing

If PGP keys are available, a lock icon (encrypt) and pen icon (sign) appear in the compose toolbar. Encryption uses stored public keys for each recipient. See PGP Encryption for details.

Contact suggestions

As you type in the To field, suggestions appear after a 200ms debounce. Indexed from your stored emails. Case-insensitive prefix search, max 5 results.

Email templates

Save frequently-used bodies as templates. Access from the compose toolbar. Manage (add, edit, delete) in Settings → Compose → Templates. Tap a template to fill the subject and body (only if they're currently blank).
