Suburban Portland, OR, 800 monthly new-mover households in 3-mile radius

Owner + 6 part-time instructors, $340K annual revenue

The challenge

Birch & Breath Yoga had a 180-member monthly autopay base and needed steady new-member acquisition to offset roughly 5%/month membership attrition. The owner had been running ClassPass for distribution (with the well-known margin compression) and Instagram ads ($4-8 cost-per-click) and converting roughly 8-12 new members a month at a blended customer-acquisition cost of $85.

Studio research from peer owners surfaced a consistent insight: new movers within their first 60 days were 3-4x more likely to commit to a yoga membership than long-term residents. The new-mover demographic was actively rebuilding routines, looking for community, and budgeting for wellness during the move-in surge. After 60-90 days, conversion rates dropped sharply as new movers settled into existing patterns elsewhere.

The owner had tried buying a new-mover list before through a national mailer; the 4-week turnaround had killed the campaign before it started. She needed a faster pipeline that could mail within 7 days of move-date, integrate with her studio management software for class booking, and not require a 5,000-piece minimum that didn't fit her single-studio scale.

The PostKnock approach

Playbook used: New-Mover Welcome

We deployed PostKnock's New-Mover Welcome playbook configured for the yoga vertical with a weekly new-mover address feed. The catchment was filtered to single-family residential moves within 3 miles of the studio (yoga commitment drops sharply beyond that radius based on retention data) and to households where at least one occupant was age 25-55. The monthly list landed at ~800 households.

Wave 1 was a 4x6 postcard with a warm welcome headline ("Welcome to the neighborhood, your first yoga class on us"), a clear single offer (one free class, any style, any instructor, no commitment), and a QR code linking to the studio's class calendar with a one-tap booking flow. The card visual was an actual photo from a recent class (with permission and compositing as needed). Community feel, not stock-yoga-pose imagery. The studio's actual class schedule, hours, and address were printed on the back.

There was no Wave 2. The new-mover decision window is narrow and a second card 4 weeks later often misses the conversion window. The owner instead ran a follow-up SMS (with explicit opt-in at first-class booking) for redemption-day reminders and post-class membership offers. Total: 800 pieces per month, 4-week rolling cohort. We measured one full cohort for the writeup.

on $660 cost

Twenty-seven first-class redemptions on 800 unique new-mover households: 3.4% response rate, solidly in the 2-4% personal-services range and lifted by the time-aligned new-mover targeting. Of the 27, 11 converted to monthly memberships at $107/month average ($1,177 month-1 recurring revenue), 6 purchased the 3-class pack ($234 transactional), and 10 took the free class but didn't convert further. Total month-1 attributable revenue: $1,411.

Campaign cost ran $660: $480 in postcards (800 at $0.60), $99 in Pro-month, and $81 in feed-integration time amortized across the cohort. Month-1 ROI of 2.1x on visible revenue is honest and modest, but the recurring revenue tail is the real story: 11 monthly memberships at $107/month with the studio's average 9-month tenure represents $10,593 in projected first-year LTV against the $660 campaign cost. First-year ROI: 16x. Cost-per-acquired-member dropped from the studio's $85 ClassPass/Instagram blended CAC to $60 from postcard, while delivering higher-LTV members (new-mover-acquired members had 11.4-month average tenure vs. 7.8 months for ClassPass-acquired).

“ClassPass gives me bargain-hunters who shop on price. The postcards give me actual neighbors who walk to class. Different members entirely.”

What we’d do differently

  • Speed-to-mailbox after move-date was the dominant variable. Cards arriving within 14 days of move converted at 4.8%; cards delayed past 30 days dropped to 1.4%. Tight feed integration is non-negotiable.
  • Studio community photo (real class, real members with permission) outperformed stock yoga imagery in pilot copy testing. Authenticity beats production polish for community-driven categories.
  • We should have offered a 3-class welcome pack as the lead instead of a single free class. Single-class converters at 41% to membership; 3-class pack converters at 70% in industry data, bigger initial commitment correlates with stickier long-term membership.
