The Challenge

Teem wanted a channel that could:

  • Break through the digital noise

  • Reach hard-to-access healthcare decision-makers

  • Feel personal without creating a heavy workload

  • Complement events, email, and other outbound efforts

  • Keep Teem top of mind without oversaturating its audience

The team believed genuinely handwritten mail would be more engaging than a traditional printed postcard.

The Strategy

Teem began by testing LettrLabs with a few thousand optometry contacts across the United States.

After the initial campaigns performed well, direct mail became part of a broader multichannel strategy. Teem rotates handwritten mail with events, cold email, and other outreach to keep each interaction fresh.

Campaigns use:

  • Event-specific audience lists

  • Personalized variable fields

  • Dedicated landing pages

  • QR codes

  • Email calls to action

  • Different messages, offers, and campaign angles

Teem found that referencing a specific event the recipient attended performed better than generic messaging based only on their profession.

Inside the Results

Lead Volume From Handwritten Mail

In strong months, handwritten mail generates up to 15% of Teem’s total leads, or approximately 10 leads.

What One Strong Month Looks Like

With each new customer worth approximately $2,000 per month and typically staying for more than six months, one month can represent approximately:

  • Six new customers

  • $12,000 in new monthly recurring revenue

  • $72,000+ in implied contract value

A Safeguard Against Costly Errors

LettrLabs also helped Teem avoid costly execution errors.

On one occasion, the team caught incorrect campaign data shortly after submitting an order. LettrLabs paused production, preventing as many as 3,000 inaccurate pieces of mail from being sent.

What’s Next for Teem

Teem is increasing its mail volume, planning to continue combining handwritten mail with events and digital outreach.

The team is also expanding the strategy beyond optometry virtual assistants, targeting healthcare-adjacent verticals with campaigns to medspas and home-care organizations.

What began as a small test is now a repeatable growth channel for Teemβ€”one that earns attention, generates qualified leads, and converts them into recurring-revenue customers.
