Comparison of Mail Shark vs SendJim Features and Benefits
Mail Shark is a solid choice for postcard printing and mailing.
SendJim is the direct mail marketing platform made specifically for home service contractors: it sends hyper-targeted mail, then automates the follow-up that actually closes jobs and drives revenue.
Bottom line: SendJim doesn’t just send postcards to get you in the mailbox. It follows up by mail, text, and voicemail, asks happy customers for reviews, and brings past customers back, so one completed job turns into your next several.
The features that actually matter when you’re running crews, closing jobs, and trying to keep your pipeline full.

SendJim is built on a hyper-targeted direct mail marketing engine for home services. Postcards, handwritten cards, letters, EDDM, and Radius Bomb neighbor mailings, sent to the right households, not just every household.
The real difference is what happens after the mail goes out. When a job closes, SendJim automatically follows up with nearby homeowners, asks happy customers for reviews, reminds past customers when they’re due for service, and keeps texting unclosed leads until they convert.
SendJim doesn’t stop when the job is done. It keeps going, triggering neighbor mailings, instant texts, voicemail drops, review requests, and repeat-service reminders automatically all triggered off Jobber, Housecall Pro, ServiceTitan, and the other CRMs you already use.

Where SendJim goes further is multi-channel automation around each job, triggered right off your CRM. One completed job can fire not just a neighbor mailing, but an automatic reminder text for recurring services, a review request to a happy client, and a voicemail drop.
If you want direct mail plus SMS, voicemail, and review automation working together SendJim is the tool for you.
SendJim’s 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. It’s a clickable feature inside your dashboard. Predictive targeting is available on the Pro Plan.
The multi-platform automation.
SendJim does the direct mail marketing as well as anyone, postcards, handwritten cards, letters, EDDM, and hyper-targeted Radius Bomb neighbor mailings, and then it automates everything around it. SMS broadcasts, ringless voicemail, gifts, and review automation, all running natively from one dashboard and triggered automatically off your CRM.
So a single completed job in Jobber or Housecall Pro fires a full multi-channel follow-up sequence: neighbors get a postcard, the customer gets a thank-you and review request, and past customers get reminded when they’re due again. Just set it up once and let your marketing engine do the work.
