Sending & Receiving Email

Copera Inbox lets you send, receive, reply, and forward emails directly inside a workspace channel — with CC/BCC recipients, rich text formatting, file attachments, AI draft replies, drafts, and support for multiple sender aliases per inbox. Once your inbox is configured with a verified custom domain, every incoming email appears automatically as a threaded conversation visible to every assigned team member in real time. You can compose from the inline composer at the bottom of a thread or from the floating compose modal, choose which alias to send from, and the AI assistant can pre-draft a reply using the full thread context.

Receiving Emails​

When someone sends an email to your inbox's primary address or any of its aliases, the message appears automatically as a new conversation thread in the inbox channel. All inbox participants can see incoming emails in real time.

Each thread displays:

  • Sender name and email address
  • Subject line
  • Preview of the message content
  • Timestamp of the latest email in the thread
  • Attachment indicator if the email contains files
  • Unread indicator for messages you have not yet opened

Composing a New Email​

To send a new email from your inbox:

  1. Open the inbox channel from the sidebar.
  2. Click the Compose button to open the email composer.
  3. Fill in the recipient fields:
    • To --- The primary recipient(s). You can add multiple email addresses.
    • CC (Carbon Copy) --- Additional recipients who should receive a copy.
    • BCC (Blind Carbon Copy) --- Recipients who receive a copy without other recipients knowing.
  4. Enter a Subject line.
  5. Write your message in the rich text editor. You can format text, add links, and insert lists.
  6. Optionally, attach files by clicking the attachment button.
  7. Click Send to deliver the email.
tip

You can also compose a new email using the floating compose modal. This allows you to write an email while still browsing other conversations in the inbox.

Replying to Emails​

To reply to an existing email thread:

  1. Open the email thread by clicking on it in the inbox.
  2. The email composer appears at the bottom of the thread, pre-filled with the reply context.
  3. Choose your reply mode:
    • Reply --- Respond to the sender only.
    • Reply All --- Respond to the sender and all other recipients.
    • Forward --- Send the email to a different recipient.
  4. Write your response and click Send.

The reply will be added to the conversation thread, and the original sender will receive it as a standard email reply. Previous messages in the thread are included as quoted content.

AI-Assisted Replies​

When Super Copera Email AI is enabled with the Draft Replies power active, the inbox automatically suggests a reply draft when you open the composer. The AI uses the full context of the email thread to generate a relevant response.

A suggestion banner appears above the composer with the draft text. You can:

  • Use this draft --- Insert the AI-generated text into the composer, where you can edit it before sending.
  • Steer and regenerate --- Type instructions in the text field below the draft (for example, "make it shorter" or "add a question about pricing") and click Regenerate to get a refined version. You can also dictate instructions using the microphone button.
  • Dismiss --- Close the banner to write your own reply from scratch.
tip

AI drafts are starting points, not finished replies. Always review and personalize the text before clicking Send. The draft is placed in the composer where you have full editing control.

Undo Send​

Clicked Send too soon? Copera gives you a few seconds to take it back — the same safety net you may know from Gmail.

When you send a new email or a reply, the message does not leave immediately. Instead, a small toast appears at the bottom-left of the screen reading "Message sent" with an Undo button, and the actual delivery is held for about five seconds. During that window you can change your mind.

What happens when you click Undo​

  • New emails — The send is cancelled and the compose window reopens with everything exactly as you left it: recipients, subject, body, CC and BCC, the chosen "From" address, and any attachments. Nothing is re-typed and nothing is re-uploaded.
  • Replies — The send is cancelled and the inline reply composer reappears at the same place in the thread with your draft restored, so you can keep editing.

After the window passes​

Once the five seconds elapse, the email is delivered for real. For new emails, a View Message button stays available for a few more seconds — click it to jump to the Sent folder with your just-sent message highlighted. The toast then disappears on its own. (Replies do not show View Message because the new message is already visible in the open thread.)

If a send fails — for example, a recipient server rejects it — the toast switches to an error with a Retry button so you can try again with one click.

tip

The Undo window is a quick fix for fat-finger mistakes — a wrong recipient, a forgotten attachment, a typo in the subject. If you spot the problem within a few seconds, click Undo, fix it, and send again. After the window closes, the email is on its way, so use the toast while it is there.

note

You can dismiss the toast at any time with its X button. Dismissing only hides the confirmation — it does not cancel an email that is already on its way. To cancel, use Undo while it is still showing.

Choosing the Sender Address​

If your inbox has multiple email addresses (a primary address and aliases), you can choose which address to send from when composing or replying to an email. The sender dropdown in the composer lets you select the appropriate "From" address.

Replies default to the address that was written to​

When you reply to an email, Copera automatically sets the "From" address to the alias the message was originally sent to — not always the inbox's primary address. For example, if your inbox owns both [email protected] and [email protected], and a customer emailed help@, your reply goes out from help@ so the conversation stays on the same address the customer used. If the original email did not match any of your inbox addresses, Copera falls back to the primary address.

You can always override this: the sender dropdown appears in both the inline reply composer and the floating compose window (for inboxes that have more than one address), so you can switch the "From" address before sending.

tip

Letting replies go out from the alias the customer wrote to keeps threads consistent and avoids confusing recipients with a different return address mid-conversation. In most cases the default is exactly what you want — just send.

Attachments​

You can attach files to outgoing emails:

  1. In the email composer, click the attachment button.
  2. Select one or more files from your device.
  3. Attached files appear below the composer with their name and size.

Incoming emails with attachments display a file indicator in the thread list. Open the email to see the full list of attachments, and click on any attachment to download it.

Contact Suggestions and Details​

Copera connects your inbox to your workspace contacts so you spend less time typing addresses and more time knowing who you are talking to.

Suggestions while you address an email​

As you type in the To, CC, or BCC field, Copera suggests matching people as soon as you have entered a couple of characters. Suggestions are drawn from:

  • Workspace members — your teammates on Copera.
  • Saved contacts — people you have added to your workspace contacts.
  • People you have emailed before — addresses Copera recognizes from past conversations, even if you never formally saved them as a contact.

Each suggestion shows the person's name, email, and avatar so you can pick the right one at a glance. Select a suggestion to drop the address straight into the field — no need to type the whole thing or remember the exact spelling.

tip

Already added a few recipients? Suggestions automatically skip addresses that are already in the field, so the list only ever shows people you haven't added yet.

Editing a recipient​

Recipients you have added appear as chips in the field. Double-click any chip to drop it back into the input for editing — handy for fixing a typo without removing and re-typing the whole address.

The contact details popover​

Hover over a recipient chip while composing, or over a sender's or recipient's name while reading a thread, and a compact contact card appears with everything Copera knows about that person:

  • Name, email, and avatar at the top.
  • A "Not in contacts" label if the address is not yet a saved contact.
  • For saved contacts: their job title, department, and company, birthday, website links, addresses, category tags, and any notes you have on file.

From the card you can:

  • Add to contacts — If the person is not saved yet, click to open the new-contact form pre-filled with their name and email.
  • Edit — If the person is already a saved contact, jump straight to their contact details to update them.
  • Copy email — Copy the address to your clipboard with one click.
tip

The popover is the fastest way to turn a one-off correspondent into a saved contact. The next time you email them, they will show up in your suggestions automatically.

Email Threading​

Copera groups related emails into conversation threads, similar to how Gmail and other modern email clients work. When someone replies to an email, the reply is automatically grouped with the original message, creating a continuous conversation view.

Each thread shows:

  • The complete email history in chronological order.
  • Individual messages with their sender, timestamp, and content.
  • Quoted content from previous messages is collapsible to keep the view clean.

Drafts​

If you start composing an email but are not ready to send it, you can save it as a draft:

  1. Begin composing your email.
  2. Click Save Draft instead of Send, or the draft may be saved automatically.
  3. Your draft will appear in the Drafts folder.
  4. To resume editing, open the draft and continue where you left off.
  5. When ready, click Send to deliver the email.

Frequently Asked Questions​

Can I unsend an email after clicking Send?​

For a few seconds, yes. After you click Send, a "Message sent" toast appears at the bottom-left with an Undo button, and the email is held for about five seconds before it is actually delivered. Click Undo within that window to cancel the send and reopen your draft with everything intact. Once the window passes, the email is on its way and can no longer be recalled. This works for both new emails and replies.

Does dismissing the "Message sent" toast cancel my email?​

No. The X on the toast only hides the confirmation — your email still goes out. To actually cancel, use the Undo button while it is showing (within the five-second window).

Which address does a reply come from when my inbox has aliases?​

By default, a reply is sent from the alias the original email was written to. If someone emailed [email protected], your reply goes out from help@, keeping the conversation on the same address. You can override this with the sender dropdown in the composer before sending.

How does Copera suggest recipients as I type?​

When you type in the To, CC, or BCC field, Copera suggests matching workspace members, your saved contacts, and people you have emailed before. Pick a suggestion to add the address instantly. Suggestions appear after you type a couple of characters and skip anyone already added to the field.

Can I see details about a sender or recipient?​

Yes. Hover over a sender's or recipient's name in a thread, or over a recipient chip while composing, to open a contact card with their name, email, and — for saved contacts — job title, company, links, tags, and notes. From the card you can add them to contacts, edit an existing contact, or copy their email address.

Can I send emails from any address on my domain?​

You can send from the primary address and any aliases configured on your inbox. The sender dropdown in the composer lets you choose which address to send from, which is useful when one inbox handles multiple public-facing addresses (for example, support@ and help@).

Can everyone on the inbox see my drafts?​

Drafts are personal — only you see your own drafts. Other inbox members cannot view or edit another teammate's in-progress email.

How large can attachments be?​

Copera itself does not impose file-size limits on attachments — you can compose a message with a large video or design file without Copera rejecting it. However, the recipient's email server (Gmail, Outlook, Yahoo, etc.) may reject very large attachments: most mainstream providers cap incoming attachments at 20–25 MB total. If a remote server rejects your message, Copera surfaces the bounce with a clear error. For big files, upload to Copera Drive and share a link instead — the recipient gets a link that works regardless of their provider's attachment limits.

Does Copera automatically save drafts?​

Copera periodically auto-saves your composition so you do not lose work if you close the tab or refresh the page. You can also explicitly save a draft at any time.

Can AI write the whole reply for me?​

When Super Copera Email's Draft Replies power is enabled, the composer opens with a pre-generated AI draft that uses the full thread context. You can click Use this draft to insert it, steer the AI with plain-language instructions (like "make it shorter" or "add a question about pricing") and regenerate, or dismiss to write your own reply from scratch.

Is email search available from the Command Palette?​

Yes. Press Ctrl+K (or Cmd+K), type ! followed by your query (for example, !invoice), and the palette searches across your connected inboxes. See Command Palette Quick Navigation for all search prefixes.
