SendJim is built on a hyper-targeted direct mail marketing engine designed specifically for home service businesses. Our predictive Lookalike Lists, Radius Bomb neighbor mailings, and Top 3% audiences are tuned to your specific service industry, not just generic templates for sales reps and marketers.
It connects natively to the CRMs contractors actually run on: Jobber, Housecall Pro, ServiceTitan, Service Autopilot, and more. When a job closes, the whole follow-up machine fires automatically: neighbors get a postcard, the unclosed quote gets a text, the past customer gets a voicemail, the happy customer gets a review request.
SendJim gives you a complete marketing system built around how home service businesses actually win and keep customers.
