One SMTP endpoint, many tenants
Point every campaign tool at smtp.sendrules.net. The AUTH credential picks the tenant; the tenant's routing rule picks the provider. No per-client SMTP re-setup.

One endpoint. Every client. Their credentials stay theirs.
Manage sending for thirty clients on their own provider accounts — one endpoint, per-client rules, no shared credentials.
Multi-tenant on their credentials
Marketing Agencies & MSPs
Four sendrules capabilities mapped to the pain that defines this segment. Every one of them is on the free plan.
- One SMTP endpoint, many tenants
- BYO client credentials
- Per-tenant DMARC monitoring
- Share-link reports
The pain
What you deal with today.
You run email for many clients. Each client has their own SES, their own SendGrid, their own domains and DMARC posture. You do not want to hold their passwords, mix their traffic, or ask them to migrate to your ESP. But every campaign tool you attach makes you set that up again.
How sendrules answers
What changes when you route through us.
sendrules is designed multi-tenant. Each client is a tenant with its own routing rules, its own provider credentials (encrypted per-tenant), its own send limits, its own DMARC domain. Your campaign tool points at one SMTP endpoint; the tenant is chosen by the SMTP AUTH credential you supply.
The four capabilities
Feature per pain, not the other way round.
BYO client credentials
Attach your client's own SES / SendGrid / Postmark account. Credentials sealed with AES-256-GCM per-tenant. You never see the plaintext, they never leave their own vendor relationship.

One tenant, one DMARC dashboard. Aggregate reports arrive at a hosted rua= address per client — no shared inbox, no manual sorting.
Read moreShare-link reports
Any filtered activity view generates a read-only public URL. Send it to a client mid-campaign; when the campaign ends, expire the link.

Concrete scenarios you can wire in this week.
- One tenant per client with their own provider fleet, their own limits, their own DMARC posture
- Nightly campaign sends from a client's marketing tool through their own SES, quality-gated so bad addresses don't spike their bounce rate
- Per-client autoresponder parsers that build lists your account team can hand back to the client via webhook or CSV
- Per-client share links so account managers can send clients a live 'here's what your campaign did' report without giving them logins
- Consolidated agency-wide view (super-admin) of provider health across every client at once
