Sender Profile Architect
A Sender Profile is the operational boundary for tenant identity, channel configuration, inherited resources, billing, and credentials. Use this skill before provisioning when a poor boundary would mix brands, compliance posture, rate-limit impact, or webhook ownership.
For live MCP profile lifecycle operations use sent-profile-provisioning; for market requirements use sent-compliance. MCP selects an acting profile with optional profileId on ordinary account tools for organization grants only. sender_profiles.* tools operate on target id and reject acting profileId. REST headers below are not MCP arguments.
Recommended tenancy model
When tenants require isolation, recommend one Sent organization with one Sender Profile per tenant. A shared profile is appropriate only when the tenants genuinely share one brand, sender resources, compliance posture, billing/rate-limit expectations, and operational blast radius.
Do not recommend pooled-by-default architecture. Make the isolation decision explicit using references/multi-tenancy-patterns.md.
