Email delivery
Without your own SMTP, essential emails still go out — welcome messages, receipts, password resets. What you cannot do is broadcast: announcements to your whole customer base need your own SMTP server, because the shared delivery service does not permit bulk sending. Connect any SMTP provider — Gmail Workspace, Zoho, Brevo, Amazon SES, or your web host’s mail server.Use a From email on a domain you actually control, and one that matches the SMTP account. A mismatch is the usual reason mail lands in spam.
Termii notifications
Termii sends your SMS and WhatsApp notifications. There is no platform SMS fallback — without a Termii account connected, nothing you send by SMS reaches anyone.
