GenieOS docs

Send through GenieOS Relay, your transactional ESP, SMTP, or a lifecycle platform while keeping one GenieOS workflow.

Connectors let GenieOS keep the product workflow in one place while the actual delivery can happen through the provider your team already trusts. Templates, approvals, schema contracts, campaigns, suppression checks, audit logs, and delivery events still live in GenieOS.

GenieOS Relay

The fastest path: hosted delivery with no external ESP setup.

Iterable

Use GenieOS templates with Iterable triggered campaigns and lifecycle reporting.

How connectors work

Every connector follows the same control flow: GenieOS validates the message, checks suppressions, hands the send to the provider, then normalizes provider webhooks back into GenieOS events.

Connector families

Family	Best for	Examples
Managed relay	Teams that want GenieOS to own delivery setup and webhooks.	GenieOS Relay
Transactional ESP	Teams with an existing ESP account, domain reputation, or procurement path.	MailerSend, SendGrid, Postmark, Resend, Mailgun, Amazon SES
SMTP	Legacy systems or providers that only expose SMTP credentials.	SMTP
Lifecycle platform	Marketing and lifecycle teams that want downstream journey analytics and suppressions.	Iterable

A workspace can keep multiple connectors installed. The active connector is selected per workspace, and GenieOS stores provider credentials server-side rather than exposing them to browsers or SDK clients.
