LettrLabs is well-known for real estate handwritten campaigns and proximity-based mailings (e.g. "just sold" cards to surrounding houses). Scribble is built for businesses that want to automate handwritten letters off of CRM events across many verticals — real estate, auto, financial services, restaurants — with deeper per-recipient personalization per letter.
Scribble and LettrLabs both send handwritten letters, but for different jobs. LettrLabs is best for real estate proximity mailings and bulk address-based campaigns. Scribble is best for businesses where every letter should reference a specific moment in a customer relationship — a closed deal, a loyalty visit, a referral, an anniversary — rather than a bulk geographic blast.
| Feature | Scribble | LettrLabs |
|---|---|---|
| CRM-event-triggered automation (HubSpot, Zapier) | Native — letters fire automatically on deal stage changes, lifecycle events, custom properties | Supported via Zapier |
| Real ink, handwritten by a pen plotter | Yes — UUNA TEK iAuto plotter writes in real ink on every letter | Yes — robotic handwriting |
| Per-recipient personalization from CRM context | Every letter drafted by our software using actual contact + deal data | Mail-merge templates; limited contextual personalization |
| Four control modes (auto, notify, review window, approve each) | Yes — choose how much oversight per trigger | Single mode (manual approval or fully automatic) |
| Restaurant / POS loyalty integration (NCR Aloha) | Built-in NCR Aloha loyalty trigger | Not supported |
| QR-scan tracking back to source CRM | Every letter includes a tracked QR code; scans write back to HubSpot | No native QR / scan tracking |
| Pricing model | Usage-based, scales with letter volume | Per-card pricing or monthly subscription tiers |
| Delivery window | 3–5 business days via USPS first-class | Typically 5–7 business days |

Scribble is best for businesses where every letter should reference a specific moment in a customer relationship — a closed deal, a loyalty visit, a referral, an anniversary — rather than a bulk geographic blast.
LettrLabs offers some CRM integrations but is primarily campaign-focused. Scribble is built around HubSpot, NCR Aloha, and Zapier triggers, with per-event letter sends — better suited to ongoing relationship workflows than campaign blasts.
For geographic farming and "just sold" proximity campaigns, LettrLabs is purpose-built. For agents who want a system that automatically sends a personalized note at every closing, every anniversary, and every referral — Scribble is the better fit.
LettrLabs is one of a dozen services doing some version of this. The full roundup weighs every one of them on real ink versus printed fonts, what each actually automates, and published pricing.
