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.”
— Abhas Gupta, CEO, Mabel

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.”

— Abhas Gupta, CEO, Mabel

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

Mabel

Drives 30–50x Higher Response Rates with Lob

  • 30–50x higher response rates compared to industry averages
  • ~5 percent average response rate from doctor-branded Medicare mailers
  • $360M+ incremental revenue generated for clients, 60% from direct mail

The Challenge - A labor-intensive, manual process

With 65 million Medicare patients, Medicare represents one of the largest sectors in the healthcare industry. However, engaging this demographic has historically been a challenge. Newer and more cost-effective marketing platforms such as social media and digital advertising have limited reach, and guerrilla tactics like spam calls and misleading TV advertisements leave patients confused and skeptical of engaging. Direct mail continues to be the most promising channel, but generic mailers sent to purchased prospect lists typically yield low response rates.

These insights led to the creation of Mabel, a healthcare communications platform that sends personalized letters to Medicare patients on behalf of the person they trust most—their doctor. Mabel uses the doctor’s electronic health records (EHR) system data to segment patients and deliver targeted messaging, helping patients change insurances, enroll in specific health programs, or better manage their health—unlocking a new marketing channel.

But with 3,000 clinics sending millions of customized direct mail pieces a year to different patient segments, Mabel knew manually stuffing envelopes wouldn’t be efficient or sustainable. They needed a technology solution to streamline the creative and sending process, enhance personalization, improve overall efficiency, and access to analytics to support the effectiveness of their marketing campaigns.

The Solution - Just what the doctor ordered 

Mabel implemented Lob’s automated direct mail solution, which provided an innovative solution centered around API functionality. Mabel leverages technology to automate direct mail on behalf of each clinic, eliminating the burden of manual, inefficient processes.

What would normally be a very tedious process of customizing mailers, reviewing proofs, and going back and forth with a printer has been completely streamlined. There’s no effort on either the provider’s part or our client’s part, making it a very effective solution for us and them. - Abhas Gupta, CEO

Mabel’s partnership with Lob enabled its clinics to customize and personalize mail pieces at a patient-to-patient level with unique logos, branding, return addresses, phone numbers, and websites for each clinic. This, in combination with the patient segmentation based on EHR data, ensures that every patient receives tailored messaging that resonates with them, optimizing the impact of the direct mail campaigns.

With Lob’s analytics dashboard and integration with USPS, Mabel can measure the impact of any given campaign in real-time and share those metrics back with its clients. 

The Results - 30-50x response rates and hundreds of millions of dollars in incremental revenue

Mabel desired a technology-driven solution and found that Lob's automated direct mail platform yielded significant results.

Direct mail response rates for Mabel’s campaigns are 30 to 50 times higher than industry norms, and Mabel’s response rates are in the double digits, with an average response rate of around 5%. This highlights the effectiveness of personalized messaging from patients' doctors. 

Gupta says, "We target the Medicare population. These folks are over 65. They're bombarded by spam calls, so they don't answer the phone. They don't typically have email addresses or check their email regularly, so there aren't good ways to reach them directly. But a letter from their doctor does get a response and gets acted on quickly. And that’s why the response rates are 30 to 50 times higher than a typical response rate from a payer sending letters out is around 0.1 to 0.25%.” 

In addition to stellar response rates,  Mabel has generated approximately $360 million in incremental revenue for its clients, with over 60% of that value coming from direct mail, with each enrollment potentially contributing up to $12,000 per year. Furthermore, campaign automation and API integration reduced operational burdens on clinics, enabling them to focus on patient care rather than manual mailings. Mabel’s personalized, targeted approach improved patient engagement, loyalty, and overall patient-provider relationships, which is priceless to the brand’s bottom line.

The Future

Looking ahead, Mabel aims to expand its reach and impact. Mabel has set its sights on penetrating the remaining two-thirds of the Medicare market and continuing to deliver innovative solutions like its integration with Lob to more healthcare providers.

Mabel also plans to introduce new products, including a survey tool for collecting patient feedback and enhancing engagement. They also plan to offer milestone-based communications to foster patient loyalty, build relationships, and ongoing engagement. Mabel envisions leveraging technology to provide smarter patient engagement, reminding patients of screenings, appointments, and personalized health recommendations.

Mabel will continue to innovate and evolve its platform to stay at the forefront of healthcare communication, ensuring improved patient outcomes, increased efficiency, and enhanced provider-patient relationships.
