Compliance-grade direct mail for healthcare.
Send appointment reminders, statements, EOBs, and patient outreach through a HITRUST-certified pipeline. BAA-ready, PHI-safe, and printed in 24 hours so you can reach patients on the cadence care actually needs.

Built for the controls your security team will ask about.
- HITRUST-certified facility
- Print, storage, and transport happen inside a HITRUST-certified environment. We sign BAAs and operate under HIPAA-aligned controls end to end.

- Patient lapse and win-back
- Reach lapsed patients who have unsubscribed from email or stopped responding to SMS. Physical mail breaks through digital fatigue.

- Annual flu, well-visit, screening reminders. Pull eligible patient cohorts from your data warehouse, fire the campaign, track responses.
- Care-gap closure
- Hit measure gaps for HEDIS, Star Ratings, and quality programs with timed nudges to non-compliant patients. Trackable, auditable, and at scale.
- New-provider and welcome kits
- Welcome new members or patients with branded onboarding packets. Insert ID cards, plan summaries, or provider directories per recipient.
What everyone is saying
Trusted by providers, payers, and digital health teams.
The HITRUST certification got us through procurement in days, not months. The BAA was clean and the API let our engineering team integrate the outreach workflow in a single sprint.

We moved EOB and statement printing onto MailStream and cut our turnaround from 5 days to 24 hours. Members notice. So does our finance team.

Appointment reminder postcards dropped our no-show rate by a meaningful margin in the first 90 days. Triggered straight off our scheduling system.
