AEP Mail That Lands On Time. Every Time.
The Annual Enrollment Period runs October 15 – December 7 — and your member letters, plan-change notices, and ID cards have to be in mailboxes ahead of it. MASS Communications produces Medicare Advantage member communications at scale, managed through PatientLetterHub Enterprise.
If your AEP program needs to be in production by early fall, the planning conversation should happen this summer.

AEP season shouldn’t run on spreadsheets and email threads
Every fall it’s the same scramble: letter versions flying around by email, proof approvals stuck in someone’s inbox, no clear record of what mailed when, and postage spend you can’t document until weeks later. At 50,000 — or 500,000 — pieces, “we think it went out” isn’t good enough for your leadership or your auditors.
One portal. One production floor. Full accountability.
- Member mailings at scale — plan-change notices (Medicare and non-Medicare), member letters, ID card mailings, application fulfillment. Monthly programs and multi-day drop schedules.
- Online proof approval — see the signed proof, approve with one click, or request changes. Nothing prints without your sign-off.
- Postal documentation — Mail.dat upload confirmations, postage spend by mail class, piece counts, NCOA processing summaries. Audit-ready.
- HIPAA built in — BAA on file before any PHI moves, PHI-safe upload architecture, every action logged with a 7-year retention trail.
- Real production capacity — we print in-house in Massachusetts. Your AEP volume isn’t in a queue behind someone else’s catalog job.

Built with health systems, not just for them
PatientLetterHub Enterprise was shaped working directly with health-system member-communications teams managing hundreds of thousands of pieces a year. The portal reflects how AEP work actually happens — recurring programs, financial parameters, postage accounting, and reporting your finance team can use.
