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 + RBAC
  • Webhook into your EHR
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 on provider errors, and logs every message with reason codes at every stage. Signed webhooks land in your PAS/EHR/CRM within seconds. IP allowlist at AUTH keeps credentials scoped to your production infrastructure.

The four capabilities

Feature per pain, not the other way round.

Automatic failover

Attach multiple providers; sendrules fails a rate-limited or errored send to the next attached provider automatically. Your appointment reminders don't sit in a queue.

Per-message audit trail

Every message logged with the routing decision, quality-gate verdict, provider used, and delivery outcome. Reason codes at every stage.

Read more →

IP allowlist + RBAC

AUTH restricted to your production CIDR, per-role permissions on every operator action, audit log of configuration changes.

Read more →

Webhook into your EHR

HMAC-signed events retried on schedule. Land 'delivered' / 'bounced' / 'opened' events in your record system within seconds.

Where it lands

Concrete scenarios you can wire in this week.

  • Appointment reminders with automatic failover so a single ESP outage doesn't cause missed appointments
  • Results-ready notifications with a signed webhook confirming the mail actually reached the patient
  • Recall campaigns with the quality gate rejecting stale addresses from your PAS
  • OOO parser capturing the covering GP during holidays and updating your on-cover list
  • Full audit log of every configuration change for internal governance

Other segments with similar shapes.

Verify every recipient in-line. Then parse every autoresponder reply for the person actually handling the account.
