AI-first platform built for home service businesses and agencies.

White-label dashboard lets agencies resell it as their own.
Specializes in robotic handwritten direct mail — letters and cards that look personally written. Has some automation capabilities for home services including new mover targeting. Lacks AI photo personalization and agency white-label. Pricing starts around $0.75+ per piece.

We're honest: LettrLabs is genuinely better for certain use cases. Here's when to consider them instead.
When targeting affluent homeowners for estate landscaping, bespoke renovation, or high-end exterior work, handwritten mail signals exclusivity and effort in a way that postcards — even AI-personalized ones — may not. If your average job value exceeds $20,000 and your list is under 500 names, LettrLabs' approach can justify its premium.
A handwritten thank-you note after a completed job remains one of the highest-conversion follow-up tools in home services. LettrLabs automates this at scale in a way that feels genuinely personal. For post-job nurture sequences aimed at referrals and repeat work, LettrLabs has a clear edge over any postcard format.
Real estate agents farming geographic areas — just listed / just sold campaigns, circle prospecting — often benefit from the tactile feel of handwritten mail. When your audience includes sellers and landlords evaluating a long-term relationship, the effort signal of a handwritten note can outperform visual property transforms.
Lower cost per piece means more mail — and more leads — for the same budget.

CurbMailers pulls a photo of the prospect's actual property and AI-generates what it could look like after your work. No other direct mail platform — including LettrLabs — can mail a before-and-after of someone's own home.
Run it under your brand. Your clients log into your-brand.com, not CurbMailers. Manage unlimited client campaigns from one seat. LettrLabs has no equivalent offering.
Every postcard gets unique QR codes, tracking URLs, and call tracking numbers. See exactly which addresses responded, which campaigns converted, and what your cost per lead is — in real time.
Upload a CSV and launch in minutes. No design agency, no print shop coordination, no days-long lead time. CurbMailers handles printing, addressing, and USPS delivery automatically.
CurbMailers uses AI to generate before-and-after photo transformations of a prospect's actual property — something LettrLabs cannot do. LettrLabs specializes in handwritten direct mail, which is personal but cannot be visually personalized to each recipient's home. CurbMailers also offers a white-label agency dashboard and real-time response tracking.
Yes. LettrLabs handwritten mail starts around $0.75 per piece and climbs quickly at lower volumes. CurbMailers AI-personalized postcards start around $0.50 per piece with volume discounts that scale well for agencies managing multiple client campaigns.
No. LettrLabs does not offer a white-label solution for agencies. CurbMailers is built agency-first — your brand, your domain, your client portal. Clients never see the CurbMailers name.
For most home service businesses — roofers, landscapers, painters, window installers — CurbMailers is a stronger fit. The AI photo transformation is uniquely persuasive: prospects see a vision of their own property with your work done. This drives response rates well above the industry average of 1–2%.
Yes. Every CurbMailers postcard includes unique QR codes, tracking URLs, and call tracking. You get a real-time dashboard showing scans, calls, and conversions — so you can prove ROI to clients and optimize future campaigns.
