Reliable + auditable
Healthcare & Life Sciences

Four sendrules capabilities mapped to the pain that defines this segment. Every one of them is on the free plan.

  • Automatic failover
  • Per-message audit trail
  • IP allowlist and role-based access
  • Webhook into your record system
The pain

What you deal with today.

A missed appointment reminder is a missed appointment; a delayed results notification is a support call. Healthcare mail can't tolerate the 'one ESP, one point of failure' pattern. You also need auditability — who sent what, when, and did it reach the patient — for internal governance.

How sendrules answers

What changes when you route through us.

sendrules routes patient mail across the providers you already trust, fails over automatically when one refuses a send, and logs every message with reason codes at every stage. Signed webhooks land in your PAS, EHR, or CRM within seconds. Credentials can be scoped by IP allowlist to your production infrastructure, so a leaked password can't send from outside the perimeter.

The four capabilities

Feature per pain, not the other way round.

Automatic failover

Attach several providers. If one throttles or refuses a send, sendrules moves it to the next attached provider automatically. Your appointment reminders don't sit in a queue waiting for someone to notice.

Per-message audit trail

Every message logged with the routing decision, quality-gate verdict, provider used, and delivery outcome. Reason codes at every stage, so an audit question has an answer already sitting in the record.

Read more →

IP allowlist and role-based access

Authentication restricted to your production CIDR ranges, per-role permissions on every operator action, and an audit log of every configuration change.

Read more →

Webhook into your record system

Signed events, retried on schedule. Land 'delivered', 'bounced', or 'opened' events in your EHR, PAS, or CRM within seconds.

Where it lands

Concrete scenarios you can wire in this week.

  • Appointment reminders with automatic failover so a single provider outage doesn't turn into missed appointments
  • Results-ready notifications with a signed webhook confirming the mail actually reached the patient's inbox
  • Recall campaigns with the quality gate rejecting the stale addresses that inevitably accumulate in a PAS
  • Out-of-office parser capturing the covering GP during holidays and updating your on-cover list automatically
  • A full audit log of every configuration change for internal governance and information-security reviews
