Problem: Manual workflows slowed outreach to Medicare patients

With 65 million beneficiaries, Medicare represents one of the largest and most critical sectors in healthcare. But this audience is notoriously hard to reach.

• Patients are bombarded with robocalls and rarely answer the phone
• Many do not use email regularly, if at all
• Generic payer mailers typically generate just 0.1 to 0.25 percent response rates

Mabel was founded to address that gap by connecting with patients through the source they trust most: their doctors. Using data from electronic health records (EHR), Mabel built a platform that allowed clinics to segment patients, tailor messages, and send branded letters directly from their providers.

As the company grew to support 3,000 clinics mailing millions of letters each year, manual processes like stuffing envelopes and managing printers became an unsustainable bottleneck. Mabel needed a solution that could scale personalization, simplify production, and deliver analytics to prove campaign effectiveness.

Solution: Lob automates personalization, sending, and tracking

Mabel chose Lob’s API powered direct mail platform to modernize and scale its operations. With Lob, clinics can:

• Personalize at scale with logos, return addresses, phone numbers, and websites unique to each clinic
• Leverage EHR data to segment patients and deliver program specific messaging at the individual level
• Automate production so mail can be created, proofed, and sent without manual back and forth
• Track delivery through USPS integrations and Lob’s analytics dashboard, with real time campaign visibility

“We target the Medicare population. These folks are over 65. They are bombarded by spam calls, so they do not answer the phone. They do not typically have email addresses or check their email regularly. But a letter from their doctor does get a response and gets acted on quickly.”

This streamlined process turned direct mail from a resource drain into Mabel’s highest performing marketing channel.

Results: Stronger engagement, higher revenue, lighter workloads

The results have been striking.

• Doctor branded letters now average ~5 percent response rates, which is 30 to 50 times higher than the typical payer mailing
• Campaigns have generated $360 million in incremental revenue for clients, with over 60 percent attributed directly to direct mail
• Each patient enrollment can drive up to $12,000 annually, creating measurable financial impact for providers
• Clinics no longer spend time managing proofs and envelopes, freeing staff to focus on patient care and engagement

Spotlight: Medicare enrollment at scale

During a recent enrollment period, Mabel supported thousands of clinics in reaching Medicare patients with personalized direct mail campaigns. Each letter included branding from the patient’s own clinic, program specific details, and clear next steps.

The results exceeded expectations: response rates in the double digits, hundreds of thousands of patients engaged, and millions in annualized revenue created for providers.

By combining trusted voices with Lob’s automation and personalization, Mabel proved that direct mail can outperform digital channels for one of healthcare’s hardest to reach populations.

Looking ahead:

Mabel plans to scale even further into the Medicare market, with a goal of reaching the two thirds of patients who have not yet been engaged through direct mail. The company is also building new capabilities, including:

• A survey tool to capture patient feedback and improve engagement
• Milestone based communications such as reminders for screenings and appointments
• Expanded personalization options to deepen provider patient relationships

“Lob has taken what used to be a bottleneck and turned it into one of our strongest capabilities. Now we can focus on creating better experiences for the communities we serve, instead of worrying about whether we can meet demand.”

With Lob, Mabel has redefined direct mail as a critical growth engine for healthcare providers, improving patient outcomes while delivering measurable business results.
