How Teem Made Handwritten Mail a High-Converting Growth Channel
Up to 15% of monthly leads and $72,000+ in implied contract value.
Teem provides remote administrative professionals to U.S. healthcare practices.
With a marketing team of just three people, Teem needed an efficient way to reach busy practitioners who had little time for social media and crowded email inboxes.
Handwritten mail now accounts for up to 15% of the company’s monthly leads.

What handwritten mail contributes:
Of Teem’s monthly leads
Monthly revenue per new customer
Implied contract value from a strong month*
*Based on approximately 10 leads per month, a 60% close rate, $2,000 in monthly revenue per customer, and at least six months of retention (Teem’s average).
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
A Steady Share of Monthly Leads
In an average month, handwritten mail generates up to 15% of Teem’s total leads, or approximately 10 leads.
Teem estimates that it closes approximately 60% of those opportunities.
What One Strong Month Looks Like
Each new customer is worth approximately $2,000 per month and typically stays for more than six months.
On those assumptions, 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, aiming to reach every priority audience at least once per quarter while continuing to combine handwritten mail with events and digital outreach.
The team is also expanding the strategy beyond optometry, 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 Teem—one that earns attention, generates qualified leads, and converts them into recurring-revenue customers.
