Admin: mail provider config (SMTP / Mailgun / Resend / SendGrid)
How to swap email provider for transactional emails (welcome emails, alerts, NPS surveys).
01
Step 1 — Pick provider
- **SMTP**: works with any SMTP provider (Gmail, SiteGround, Office 365). Easiest start.
- **Mailgun**: HTTP API, free tier 5k emails/month.
- **Resend**: HTTP API, modern, 3k/month free.
- **SendGrid**: HTTP API, enterprise-grade.
02
Step 2 — Set up DNS (any provider)
- Add SPF, DKIM, DMARC records to your sending domain.
- Aim for mail-tester.com score ≥ 9/10.
- Without DKIM, emails go to spam.
03
Step 3 — Configure in /admin/mail
- Pick provider, paste credentials.
- From email: notifications@yourbrand.com.au
- From name: Your Brand
04
Step 4 — Send test email
- /admin/mail → Send test email.
- Should arrive within 30 seconds.
- If not: check SPF/DKIM via mail-tester.com.
05
Step 5 — Monitor delivery
- Mail providers all have delivery dashboards — watch bounce rate.
- Bounce rate >5% = list hygiene problem (clean your invite list).
- Spam complaints >0.1% = subject lines / content review needed.
