Teams and roles

Bring the whole team in. Without giving everyone the master key.

Owner, Admin and Sender roles by default; custom roles you define per workspace, mapped to fine-grained permissions across every resource sendrules ships. Every action captured in an immutable audit trail your compliance team can actually export.

Sound familiar?

One shared login, and everybody knows the password.

The developer needs to add a webhook. The marketer needs to check yesterday’s open rate. The finance controller needs the invoice. Your ESP has one login per account, so you either share the master credential and hope nobody deletes a provider, or you tell everyone to ask you. Neither is a policy — and neither passes a security review.

sendrules ships with role-based access from the first send. Group people into teams, give each team the permissions they actually need, and audit every mutation so the answer to “who changed the send rule at 3 a.m.?” is a query, not a Slack thread.

Roles

Three defaults. Custom roles when you need them.

Owner
One per workspace. Only role that can transfer ownership, delete the workspace, or add another Owner. Signed off on billing.
Admin
Everything an Owner can do except the four Owner-only actions above. Can invite, rotate credentials, change plans, and delete providers.
Sender
Can send, view Activity, view Deliverability, and read most of the workspace — but cannot rotate credentials, add or delete providers, invite members, or edit routing rules. The safe default for a developer or campaign operator.
Custom roles
Compose your own from the permission catalogue. Common examples: a “Compliance viewer” that sees Activity and DMARC monitoring but nothing else; a “Contractor sender” that can send on one specific rule and read only their own activity.
Permission catalogue

Fine-grained. Not the two-tier “admin or member” shortcut.

30 resource types
Providers, rules, ramps, inboxes, parsers, DMARC domains, Postmaster domains, blocklists, seed-list runs, webhooks, API keys, suppression lists, allowlists, quality-check-failed lists, team members, roles, activity, deliverability settings, retention, and every workspace-level setting — each with its own view / create / edit / delete / action verbs.
Action verbs, not booleans
A permission is a verb on a resource type, not a global switch. “Can view providers” is separate from “can rotate provider credentials” is separate from “can delete a provider” — matches how procurement actually reviews access.
Everything gated, no ghost UI
The tenant UI shows every feature to every role — nothing is hidden. When a role tries to act without the permission, they see an inline explanation and a link to request access from an Admin. No surprise-blocked buttons after five minutes of setup.
Teams

Group people. Assign teams to rules. Rotate members without touching permissions.

Teams contain members
A member can belong to more than one team. A team can be assigned to specific routing rules so campaign operators see only the rules they own.
Assign roles at the team level
Give a team a role once; add or remove members without re-configuring anything. A departing employee is removed from the team and access disappears immediately — no orphaned permissions to hunt for.
Agency and MSP patterns
Marketing agencies use one workspace per client with a shared “Agency operators” team assigned to every one; the client keeps ownership of provider credentials while the agency does the day-to-day sending. See the Marketing Agencies page for the specific setup.
Audit trail

Every mutation captured. Every actor named. Nothing gets lost.

Full field-level diff
Every privileged action — a rotated SMTP password, an added provider, a paused ramp, a member invited, a role changed, a webhook edited — captured with actor, timestamp, source IP, and a before/after diff of the affected fields.
Retained for the audit window
The audit trail respects the workspace retention window (14 to 360 days per plan) — long enough to answer “what happened last quarter” without asking the ESP for a data export that takes a week.
Export on request
Every log entry is CSV-exportable. Regulator-ready evidence for internal SOX, ISO 27001 access-control audits, or a customer’s SIG questionnaire.
Immutable in-app
No UI to edit or delete audit rows. Retention purges old rows on schedule; nothing in between overwrites.
SSO and Enterprise

SAML SSO, SCIM provisioning, and named-engineer support on the Enterprise tier.

Below Enterprise, password authentication over TLS with optional TOTP is standard on every plan. Enterprise adds SAML single-sign-on with your identity provider (Okta, Azure AD, Google Workspace, Auth0, and any SAML 2.0-compliant IdP), SCIM 2.0 just-in-time provisioning so a de-provisioning event in your IdP removes access everywhere, and a named engineer for the initial rollout so nobody guesses which attribute maps to what.

Enterprise-grade access, from your first send.
