Communication Settings

Configure a custom SMTP server so Caska can send customer-facing emails through your own email address and domain.

Caska can send emails on your behalf using your own email server. This is optional — if you don't configure custom SMTP, Caska uses its own email system for all outbound messages.

Setting up custom SMTP

Go to Settings → Communication

Find the Communication section in your account settings.

Enter your SMTP server details

Host (e.g. smtp.gmail.com, smtp.mailgun.org)
Port (typically 587 for TLS or 465 for SSL)
Username and password
From name and from email address

Save and send a test email

Click Send Test Email to verify the connection is working before relying on it for customer emails.

Troubleshooting

If test emails aren't arriving:

Double-check your SMTP credentials
Make sure your email provider allows third-party SMTP access
Gmail users need an App Password rather than their regular account password — standard Gmail passwords won't work with third-party SMTP

The Follow-Up (re-engagement) system always sends via Caska's system email (Mailgun), regardless of your custom SMTP setting. This ensures reliable automated delivery.
