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.

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.

For more details about AI-powered email features, see AI Email Intelligence.

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.

This is useful when a single inbox handles multiple email addresses and you want to reply from the same address the original email was sent to.

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.

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 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.
