Composing Emails

Bulwark's composer provides a rich editing experience for crafting emails.

Rich Text Editor

The editor supports full formatting:

Bold, italic, ~~strikethrough~~, and underline
Ordered and unordered lists
Inline hyperlinks
Tables (insert and edit)
Block quotes
Code blocks
Inline images with a resizable image component (embedded as data URLs so drops don't duplicate attachments)

Choose which sender identity to use from the dropdown in the composer. Each identity can have its own name, email address, and signature. The identity manager refreshes from the server after create, update, and delete operations so the composer stays in sync with server-side changes.

Auto-Select Reply Identity

When replying to an email, Bulwark can automatically select the identity that matches the recipient address of the original email. This is configurable in settings.

Reply-To Addresses

Configure reply-to addresses in the composer to direct replies to a different address than the sender identity.

From-Header Override and Catch-All Auto-Reply

When you own a catch-all domain, replies to mail sent to an arbitrary alias (e.g. marketing@yourdomain.com) should come back from the same alias - even when it isn't a configured identity. Bulwark detects this and pre-fills the alias as the From header in the composer. You can still override the From header manually before sending.

Signature Position

Each identity can choose whether its signature appears above or below quoted text on a reply or forward. The default fallback is the primary identity's signature. The setting is searchable from the email behavior settings.

Composer Modes

Bulwark supports two composer modes:

Rich text - Full formatting with the rich text editor (default)
Plain text only - A simplified plain text composer for users who prefer unformatted emails

The composer mode can be configured in email settings.

Attachments

Drag and drop files onto the compose window
Click the attachment button to browse
Maximum file size is determined by your Stalwart configuration
Inline images can be pasted directly from the clipboard
Resizable image component for adjusting inline image dimensions
Direct image upload support in the rich text editor
Forgotten-attachment warning - if the body mentions "attachment", "attached", etc. but no file is attached, Bulwark warns before send

Signatures

Set up multiple signatures via identity management:

Each identity has its own signature
Signatures are automatically appended based on the selected identity
Switch identities (and signatures) using the dropdown in the composer

Templates

Insert reusable email templates from the compose toolbar:

Browse templates by category with search and filter
Placeholder variables (e.g., {{recipientName}}, {{date}}) are auto-filled from composer context
Custom placeholders prompt for input on insertion
Press T in the email list or Ctrl+Shift+T in the composer to open the template picker
Manage templates from Settings

S/MIME Compose Controls

Enable or disable signing per message when an S/MIME identity certificate is available
Enable encryption when every recipient has a known public certificate
Unlock protected keys on demand from the composer without leaving the draft
Keep default signing and encryption preferences in the S/MIME settings panel

Drafts

Emails are auto-saved as drafts every 60 seconds (configurable in settings). You can also manually save with Ctrl+S. Drafts sync across devices via JMAP. A discard confirmation dialog appears when closing an unsaved draft.

Existing drafts can be reopened and edited - click a draft in the Drafts folder to resume editing with all content, recipients, attachments, and identity selection restored.
