Comparison of Mailbox Power vs SendJim Features and Benefits

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 vertical, not generic templates for sales reps and network 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.
Mailbox Power gives you cards, gifts, and a campaign builder you can use in any industry. SendJim gives you a complete marketing system built around how home service businesses actually win and keep customers.

Not really. Mailbox Power markets “unlimited free postcards” on every plan, but here’s the actual math: their Pro plan is $99.99/month and Executive is $199.99/month, and on top of that you pay USPS postage per piece — $0.61 per 4x6 postcard, $0.78 per 5.5x8.5 postcard or greeting card. Gifts (cookies, brownies, coffee mugs) are billed per item.
So a 4x6 mailing on the Pro plan really costs you the $99.99 monthly fee plus $0.61 per card mailed. SendJim’s pricing rolls postage into the credit price, so what you see on your invoice is what you actually paid — no separate postage line, no surprise fees at the end of the month.
Both platforms send postcards, cards, and gifts — so on the surface they look similar. The difference is who they’re built for.
Mailbox Power is a general-purpose direct mail and gifting tool used across many industries: sales reps, real estate agents, network marketers, B2B accounts. The campaigns, templates, and automations are built to be flexible across all of them.
SendJim is the hyper-targeted direct mail marketing platform built specifically for home service businesses. Predictive Lookalike Lists tuned to your service vertical, Radius Bomb neighbor mailings around completed jobs, and native integrations with Jobber, Housecall Pro, ServiceTitan, Service Autopilot, and the other CRMs contractors actually run on.

If you’re a contractor, SendJim is built around how your business actually works
This is one of SendJim’s flagship features. Our AI Lookalike Lists identify the roughly 3% of homeowners in a given area most likely to buy your service, based on 250+ demographic, property, behavioral, and psychographic signals — tuned to your specific service vertical.
Mailbox Power offers an “AI Prospecting Suite” that includes Visitor Reveal and Intent Finder — useful for B2B prospecting, but not the same as a productized predictive model that scores residential households on their likelihood to need your home service. With SendJim you’re mailing only the homes the model says are about to need your service.
SendJim gives every customer a personal account manager and backs it up with a real human support team. Actual people who answer the phone, jump on chats, and help you set up campaigns, troubleshoot integrations, and refine your strategy — not a ticketing queue. The team knows home service contractors, your CRM, and what actually works.
Mailbox Power offers self-serve onboarding plus group Q&A calls on the Pro plan, with 1-on-1 priority support and a one-time onboarding call on the Executive plan. Their support is built for a mix of industries. SendJim’s is built specifically for home service businesses, with a named contact who understands your goals.
SendJim is built for one type of customer — home service contractors — and everything in the product reflects that. Hyper-targeted direct mail marketing tuned to home services. Native integrations with the CRMs you already use. SMS broadcasts, ringless voicemail, gifts, and review automation all running natively from one dashboard and triggered automatically off your CRM. Pricing that rolls postage in so what you see is what you pay. And it’s month-to-month, no cycle notice, cancel anytime.
Mailbox Power is a flexible card-and-gift tool that works for many industries. If your business doesn’t live or die by hyper-targeted direct mail to homeowners and CRM-triggered follow-up, that flexibility may be exactly what you want. If it does, SendJim is built for that.
