Email sender identity

Every email JustBook sends — confirmations, reminders, receipts — goes out with a sender name and address. By default it sends from JustBook’s managed address with a name you choose. If you’d rather send from your own mailbox, you can do that too. This page covers both.

Set the From name on the default sender

Section titled “Set the From name on the default sender”

On the JustBook default email sender, customers always see a fixed address — noreply@justbookapp.com — but you control the name shown next to it in their inbox.

  1. Go to Settings → Integrations → Messaging & Email.
  2. In the Email (SMTP) section, leave Use my own sender unchecked.
  3. Enter a Sender name — for example, Marigold Studio. Customers then see Marigold Studio <noreply@justbookapp.com>.
  4. Click Save Changes.

Leave the name blank to fall back to your business name. There’s nothing else to set up — the default sender is managed and ready.

Send from your own mailbox (SMTP)

Section titled “Send from your own mailbox (SMTP)”

If you want emails to come from your own address, connect your own mailbox. This is a Pro-plan feature.

  1. Go to Settings → Integrations → Messaging & Email.
  2. In the Email (SMTP) section, turn on Use my own sender.
  3. Fill in your mail provider’s details:
    • SMTP Host and Port
    • SMTP User and Password
    • From Email — the address customers see (must be a verified sender with your provider)
    • From Name — the sender name, usually your business name
  4. Click Save & Send Test to send yourself a test email and confirm it works.
  5. Click Save Changes.

Once the test passes, your emails send from your own address. If a test fails, JustBook keeps sending from the default address so your customers still receive their emails — fix the details and run the test again to switch back.

A test that sends isn’t the same as delivered. A mail server can accept a message and still not deliver it. Send a real test to an inbox you can check, and make sure your From address is properly verified with your provider.

Which one should I use?

Section titled “Which one should I use?”
  • Just want your business name in the inbox? Set the sender name on the default sender — quickest, nothing to configure.
  • Need emails to come from your own domain? Connect your own mailbox (SMTP).

The same choice exists per channel for SMS and WhatsApp — see Notification channels.
