Integrations
Resend
Reliable email delivery for estimates and invoices.
Overview
Reliable email delivery for estimates and invoices.
Resend delivers transactional email with high deliverability. Connect an API key and verify your sending domain.
Connected services
Integrations extend what TreeOS can do — accept cards, send SMS, deliver email, store photos, and show maps. Connect them from Settings → Integrations with credentials from each provider’s dashboard.
Best practice
Connect email before your first customer-facing send. Test with your own address so bounces do not hit real clients.
