How to Configure Outgoing Email for Reliable Delivery
Reliable email setup is critical for invoices, access details, and customer notifications.
Step 1: Open mail settings
- Go to Configuration > System Settings > Mail.
- Select SMTP (recommended).
Step 2: Enter SMTP details
- Enter SMTP host, username, password, port, and encryption type.
- Set a professional sender address (for example: support@yourbusiness.com).
- Save settings.
Step 3: Send test emails
- Send at least one test email to a normal inbox.
- Check inbox and spam folder.
- Confirm links and formatting render correctly.
Step 4: Strengthen domain trust (recommended)
- Add SPF, DKIM, and DMARC DNS records for your sender domain.
- Re-test after DNS updates propagate.
What to test before go-live
- Invoice email delivery
- Payment confirmation email delivery
- Access details email delivery
