Composing and Sending

Here's everything about writing mail: opening the composer, choosing the From account and signature, scheduling, undoing a send, and how drafts are saved.

Opening the composer

C opens a blank composer (in the Tasks view it creates a new task); R, A and F open the inline composer inside the conversation.
The From account defaults to the selected account, or to your Main account when All Accounts is selected.
On desktop, the From selector sits on the To line, in the column directly above the BCC label, and BCC shares a line with CC.
Recipient fields autocomplete from the people you email most: WonderMail counts how often you write to each address and offers the top ten when the field is empty, and searches every remembered address once you type. Suggestions only appear once you type the first character in To, CC or BCC, so an empty field never covers the rows below it. Use the Up/Down arrow keys to highlight a suggestion and Enter to insert it; the highlighted row stays in view while you cursor through a long list. Esc closes the suggestion list and keeps you in the email; a second Esc closes the email as usual.
The address book is shared across all your connected accounts, and it is built from everyone you have sent mail to — including mail sent from Gmail or another client that WonderMail has synced. Your own connected account addresses are suggested too, listed first and marked “Your account”, so copying or blind-copying yourself takes one keystroke; they are not stored in the address book, so they have no Remove option.
Each address you add to To, CC or BCC becomes a chip with an x. Press Enter or Tab to accept a complete address even when it is not already in autocomplete; click the x to remove it. Backspace on an empty field pulls the last chip back for editing. Double-click any chip to edit that address.
Hover or click a To, CC or BCC chip to see the full address with a copy button, so you can copy it in one click.
Drag a chip from To, CC or BCC onto another of those fields to move it there — handy when someone should be copied instead of addressed directly.
Drag a sender or recipient name from a prior email (or its full address in the hover card) onto the current draft’s To, CC or BCC field to copy the address there. Existing recipients and unfinished typing stay in place, and an address already in that field is not added twice. Open BCC first if it is hidden. Native dragging requires a browser and device that support it.
In a brand-new email or a forward the cursor starts in the To: field. Press Enter to accept an address (typed, or picked from suggestions with the arrow keys) and move straight to the Subject field; press Enter or Tab there to land at the very start of the body. Replies open with the cursor in the body, ready to type, because the recipient and subject are already filled.

Signatures

⌘G opens the Signatures menu in the compose toolbar. Pick a signature for this email, star one to make it the default for the mailbox in the From selector, choose No signature, or toggle Auto-display for that mailbox. Use the Up and Down arrow keys to move through the list and Return to pick one. The small ? beside Signatures explains this at a glance.

The first time you open the composer, WonderMail creates a "Default" signature for you reading "Best regards," followed by your own name; edit or delete it any time in Settings → Signatures.

Signatures can also be deleted while you write: open a signature for editing from the Signatures menu and click Delete at the bottom left of the dialog.

Creating or editing a signature while you write leaves the current message, recipients and subject exactly as they are.

The signature sits in its own space one blank line below the message body and moves down or back up as you type or delete lines. Hover it for a pencil to edit the signature or an X to drop it from this email.

On mobile the signature uses the same one-blank-line spacing below the body, along with that mailbox's default signature and Auto-display setting; tap the X on the signature to drop it from this email.

After an email sends or is scheduled, WonderMail remembers the signature—or No signature—used for each To and CC recipient. Adding that person to To or CC switches the signature to the remembered choice straight away, even after you picked one by hand (a reopened draft keeps its saved signature until you change its recipients); with several recipients, the first To address with a remembered choice wins, then CC. You can still change it afterwards.

Pro Tip: star a signature per mailbox once in the Signatures menu. Every email from that address then signs itself correctly with no thought.

Meeting links

The video-camera button in the compose toolbar inserts a saved meeting link. Click it, pick a link, and WonderMail drops your own wording plus the clickable address at the cursor, for example "Here is a meeting link: https://zoom.us/j/1234567890". The text is ordinary text you can edit afterwards.

The thumbs-up button beside it answers fast: in a reply it replaces the suggested draft with one large 👍 (your signature stays); in a new email or forward it inserts a 👍 at the cursor.

To link words you have typed, highlight them and press ⌘/Ctrl+K, then paste or type the web address and press Enter. The words stay and become a clickable link.

Add, rename, reorder or delete meeting links in Settings → Meeting links, or without leaving the email you are writing by choosing Edit links… at the bottom of the button's list. Each link has a name, a web address and its own wording, where {link} marks where the address goes; star one to offer it first.

Sending

⌘Enter (Ctrl+Enter on Windows) sends the email immediately from the composer.
⌘S (Ctrl+S on Windows) saves the email as a draft without closing the composer and confirms with a "Draft saved" notice.
Schedule opens the schedule-send picker (also on H). Once a message is scheduled the compose box closes and stays closed — the message waits in Settings → Scheduled, where it can be cancelled before it goes.
Editing a scheduled email (Settings → Scheduled → pencil) opens it at the very top so the draft is visible right away, with Save and Cancel beside Send: Save keeps the same send time and stores the edits, Cancel closes the composer and leaves the scheduled email unchanged.
Send shows a 10-second countdown with an Undo button and an Accelerate button. Undo pulls the message back and puts the draft into Drafts with its original reply context. Accelerate sends immediately and skips the rest of the wait. Both buttons sit on their own row under the address, so they stay visible however long the address is; a long address wraps at the “@” and is trimmed if it still does not fit. Undo is the only thing that stops a send: the ⌘/Ctrl-Z shortcut, which undoes archives, moves and deletes, deliberately does not cancel a send.
If your mail provider is briefly busy, WonderMail waits 60 seconds and tries again, up to three times, showing a "Still sending…" notice. Press U to retry straight away. You are told the email was not sent only if all three retries fail, and your reply comes back ready to resend. Every try is listed in Settings → Activity.
Every send is recorded permanently: when Send was pressed, the countdown, whether the mail service accepted it, and, if it was stopped, the exact cause and time (the Undo button, the reply box closing, the page being closed or reloaded, another send taking its place, or an app error). Settings → Activity → Copy send log copies that record; it holds recipients and subjects only, never email text. Settings → Activity also lists Recent send failures — every send the mail service refused in the last 30 days, with the time, recipient, subject, Failure ID, the exact reason it gave, and whether a later attempt on the same conversation went through.
Archive after sending (Settings → General, on by default) archives the conversation as soon as you send a reply, reply-all or forward. It also applies when you schedule a reply or forward: the conversation leaves Inbox as soon as the send is scheduled. The Send Undo button cancels the send, restores the draft and returns the conversation to Inbox; undoing or cancelling a scheduled send also returns it to Inbox. Turn the setting off to leave replied-to and forwarded conversations where they are.
When you reply or forward on the desktop, the Send button has a small arrow with two immediate actions: Send & Archive sends the email and archives its conversation (in a conversation split into one row per sender, only the email you answered is archived and the other senders' emails stay in their box); Send sends the email without archiving. The main button starts on the action that matches your Archive after sending setting, and the send keyboard shortcut does whatever the main button shows.
Once a reply or forward is sent, the writing box closes for good: it never comes back holding the text you just sent. The conversation shows the email you answered, with a collapsed "You replied" (or "You forwarded") strip above it — click the strip to read what you sent, click again to fold it away. Clicking a search result for your own reply shows that reply open instead of folding it. In Follow-Ups, your own newest email (the one you are waiting on) also shows open instead of folded. The AI summary strip is hidden there too, since it would describe the email you already answered. A sent email can no longer be edited, so the edit and remove controls are never offered in Sent.
Hover the time under any email's sender to see two IDs you can copy: that individual email's own Email ID first, then the Conversation ID for the whole exchange. Every email has its own ID, including ones you sent. Pasting either ID into the search box opens that conversation, and the first eight characters are enough. If an ID matches nothing at all, search says 'No email found with that ID' instead of the generic 'No results'.
The Remind toggle beside Send sets a reply reminder automatically when the message goes out — see "Reply Reminders".
WonderMail blocks sending a message with an empty body so an accidental blank email never reaches a recipient. A picture in the email body or an attached file counts as content, so you can send an image-only or attachment-only email without adding text, and forwards never need a message. It also blocks a send with no recipient at all and tells you to add an address in To, Cc or Bcc.
An incomplete address is caught before it can reach the mail service. A finished entry that is not a full address (for example leslie@leslieblai) is marked in red in the To, Cc or Bcc box, and pressing Send, using the send shortcut, or scheduling the email stops the send: nothing goes out, your email stays open exactly as you typed it, the cursor is placed in the offending box, and a notice names the field and the text to finish. Fix the address (or pick the name from the dropdown) and press Send again.
If a send fails, a notice says "Error: Email NOT sent", always shows the To: address you were sending to, and says "Your draft is back in the composer, ready to resend." When the cause is recognised, the next line says what to do instead: files too large, a recipient address refused, an account that needs reconnecting, or a mail service that is busy. The "i" button on that notice opens Debugging Info with a copy icon, holding the time, app version, composer, account, the recipient addresses and counts, subject length, attachment count and size, conversation id, Failure ID, and the exact message and reason from the mail service — never any email text. An alert email with those details also goes to the WonderMail owner. Nothing is lost: the conversation goes back to the box it was in when you pressed Send (returning from Archive if it had been archived), you are put back in that box with the conversation open, and the email opens again exactly as you typed it—recipients, subject, body and files—and is saved in Drafts.
Attachments are checked before the send goes out: if the files on an email (including those carried over from a forward) total more than 25 MB, the composer says so above the file list and refuses the send, so an oversized email never fails silently at the mail service.
Pictures pasted or inserted into the body of an email are shrunk automatically as they go in: the longest side is capped at 1600 pixels and the picture is saved at photo quality, so a large screenshot or phone photo drops from several megabytes to a few hundred kilobytes. Small pictures and animated GIFs are left exactly as they are, and files you attach with the paperclip are never changed.
Click a picture you pasted or inserted into the email body to show corner handles, then drag a corner to make it larger or smaller. WonderMail keeps the picture's proportions and stops it from becoming wider than the writing area, so the whole picture stays visible.
A pasted picture stays in the email, including in a saved draft or scheduled email you reopen later, and it is sent with a matching embedded-image reference so Gmail, Yahoo, Outlook, Apple Mail and other mail programs show it in place rather than as a stray file or empty box. The Sent copy keeps that same embedded picture.
The whole email is measured before it leaves the composer, body pictures included: if it would exceed the 35 MB the mail service allows, the send is stopped with "This email is too large to send (over 35 MB including images). Remove or shrink the largest pictures or files and try again." and your draft stays exactly as it is.
Pictures from the earlier emails quoted under a reply are re-attached so the recipient sees them. If they would add more than 25 MB, the oldest quoted pictures are replaced with "[picture removed — too large to resend]"; your own text, pictures and attached files are never removed.
Like Gmail, a sent reply quotes only the newest earlier email, because it already contains the rest of the conversation. A note says how many older emails were not repeated. A quoted email bigger than about 2 MB is shortened, with a note; your own text, pictures and attached files are never removed.

Pro Tip: the 10-second countdown is a real recall. If you spot a typo or a missing attachment the moment you hit Send, click Undo and your draft returns to Drafts with its reply context intact.

Attachments

Click the paperclip in the composer toolbar, or drag one or more files from your computer anywhere onto the open desktop compose pane, to attach them. Each file becomes a chip under the body: click the file name for a menu with Preview and Download, or the x to remove it before sending; the total across all files is capped at 25 MB. The same menu works on files carried over when you forward an email.
Where you drop a picture decides what happens to it. Drop a picture inside the writing area and it goes into the email at that exact spot as an inline picture, shrunk the same way a pasted picture is; drop it anywhere else on the compose pane (headers, toolbar or file row) and it is attached as a file instead. Files that are not pictures are always attached, wherever you drop them. Dropping several files at once treats each one by the same rule, and it works the same on Mac and Windows. The draft is saved the moment a file lands, so nothing is lost if you close the email or the browser, and the files come back when you reopen the draft.
Attachments work with scheduled sends too — the files are stored securely and go out with the message when it sends.
Pictures embedded in the body of an email are matched to the stored image files by the id the message gives them. A few emails arrive without those ids; WonderMail first checks whether the embedded reference exactly matches an image filename, then matches remaining pictures to stored inline images in the order they appear, so the message still looks the way the sender intended — in reading and when you forward it.
Attachments you receive stream from your provider on demand, including inline images embedded in the message body. Each attachment card has two buttons — Preview (opens it below the email straight away with a loading message and scrolls it into view, or says so with a Download option if the file can't be shown; PDF, images, Word, Excel, CSV and attached emails (.eml) up to 5 MB; an attached email shows its sender, date, subject and message, keeps web images hidden until you click Show images, and lists its own files without opening them) and Download (saves it to your computer). For Word and Excel files, Preview shows the file rendered in your browser: a spreadsheet as a proper grid, a Word document as readable text. A CSV is read as a grid too (your original CSV is untouched and Download still gives you it). When an email has two or more attachments, a Download all button above the cards saves every file in a single .zip named after the email subject; files with the same name are numbered (2), (3) and so on, and if any file can't be fetched a notice names it and no zip is saved.
Drag an attachment card out of WonderMail and drop it into any folder on your computer (Finder on a Mac, File Explorer on Windows) to save the file there. The same drag works on attachment chips in the compose pane. Hovering the card or chip gets it ready, so the drag saves the real file, not a link. If you drag before the file has finished loading, WonderMail says so and the next drag works. This uses Chrome or Edge; in other browsers use Download.
PDFs are drawn by WonderMail itself rather than handed to the browser's built-in viewer, so Preview shows every page inside the email instead of a grey placeholder, and Escape and the arrow / J / K keys keep working while the preview is open. If a PDF cannot be drawn, the preview says so and Download still works.

Typing shortcuts

Typing -> in the message body turns it into a right-pointing arrow (→) as soon as you type the second character, in a new email, a reply or a forward, on desktop and mobile.
Text you paste, quoted history and a reopened draft keep their plain -> exactly as written; only characters you type are changed.
If the arrow was not what you wanted, ⌘Z removes it the way it removes any other typing.

Auto-capitalize

Auto-capitalize (Settings → General, on by default) capitalizes the first letter of each sentence as you type, including after ., ! and ?. If you want a lowercase letter, backspace right after the capital appears and type the lowercase one — WonderMail will not change it back.

Auto-capitalize names (Settings → General, on by default) capitalizes the name after a greeting — typing hi wendy gives Hi Wendy, and pressing Return after a bare greeting like Hi Hana adds the comma for you — and any word in your message that matches a name in the To, CC or BCC lines. Backspace the capital and type the lowercase letter to keep it lowercase; WonderMail remembers that choice for the rest of the email. Turn it off in Settings → General.

Drafts

If an email already has a saved draft, opening that email restores the draft automatically. The composer does not take focus, so email shortcuts keep working — click into the message body to carry on writing.
A conversation keeps a single saved draft — saving again replaces the previous one instead of piling up duplicates in Drafts.
In Drafts, a single click on any draft opens it straight away for editing; its conversation loads underneath a moment later. The draft you are editing is highlighted in the list, the same way a selected email is highlighted in every other box.
In Drafts, the side rail offers only Trash, which deletes the open draft; the trash icon on a draft row does the same for that draft.
Files attached to an email that failed to send are kept with its draft, so they are still attached when you reopen it later.
A draft you started with Forward comes back in Forward mode when you reopen the email; replies come back as replies.
Drafts auto-save to your account every 5 seconds while you write — replies, forwards and brand-new emails alike. It runs quietly: no toast, no cursor jump, and nothing is written when the composer has not changed.
A live copy is also kept in your own browser about a second after you stop typing, so a page reload or a crash cannot lose what you wrote. Reopening the email restores whichever copy is newer, with one safeguard: when the two copies were written within moments of each other, the longer one always wins, so a shorter copy saved a fraction of a second later can never replace what you typed. The browser copy is cleared when you send, schedule, or discard with x.
Clicking another email always opens that email in the reading pane and immediately saves the open message as a draft, including brand-new emails and the last words you typed a moment earlier. Switching mailboxes, closing the box, or leaving the app also saves it immediately.
The signature showing when you left, including No signature, is saved with the draft. Reopening from Drafts or search restores that choice instead of picking a default. On desktop, changing only the signature also counts as an edit and is saved when you close the composer.
