Send email from your own SMTP server

By default, Reonic sends email on your behalf. To have your customer-facing emails come from your own server instead, connect it under Settings > Company settings > Integrations > SMTP Mail Server. Only end-customer emails are rerouted. Sign-in links and system notifications continue to send from Reonic.

Before you start

• You need admin rights, and your SMTP Mail Server needs to be available for your workspace. If the card shows as inactive, contact your Reonic account manager.
• Your SMTP server's hostname, port, username, and password. The server must support STARTTLS (default port 587).
• A sender address if your login username isn't a valid email address. This is the From address customers see.
• An app-specific password if your mail account uses multi-factor authentication. Your normal password usually won't authenticate against MFA accounts.
• SPF/DKIM set up for your sending domain on your side, so the mail isn't flagged as spam.

Connect your SMTP server

1. Open Settings > Company settings > Integrations and open the Custom SMTP Mailserver card.
2. Enter Hostname (e.g. smtp.domain.com), Port (587 for STARTTLS), Username, and Password.
3. Fill in Sender address if your username isn't an email address. Otherwise leave it. Reonic uses your username or company email as the sender.
4. Click Send test email. Reonic sends a test message to your address with a code in the subject. If it fails, you'll see an error with a STARTTLS or app-password hint. Fix it and retry.
5. (Recommended) Enter the code from the test email to confirm delivery, or skip the check.
6. Click Save configuration and confirm. From now on, customer-facing email sends through your server.

Pro tip: Saving sends an email notification to all other admins on your account. Every change also requires re-entering the password.

Manage the connection

• Edit: open the card and choose Edit settings. Re-enter the password, since it isn't shown back to you.
• Remove: use the disable toggle and confirm. This clears the configuration, so re-enabling later means entering all credentials again.

Things to know

• Only customer-facing email is rerouted. That includes Can't fulfil request, Need more information, Lead information, New offer available, Updated offer available, and Signature completed. Sign-in links, task assignments, and other system emails continue to send from Reonic.
• STARTTLS is required. Port 587 is the default; some servers differ. Reonic checks the connection before saving, so a wrong port or unsupported encryption is caught immediately. If your test email doesn't arrive, the port or encryption is the usual cause, and the error banner names it. On MFA accounts, use an app-specific password.
• You handle deliverability and bounces once it's active. Email sent through your server bounces on your server, so monitor your own mail logs.
• The password isn't shown back to you. Any edit requires re-entering it. Removing the server clears every field, so re-enabling later means entering all credentials again.
