Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

PostKnock overview
What is PostKnock?
PostKnock is a direct-mail automation platform that unifies USPS postcard campaigns and outbound phone follow-up in a single, trackable workflow. It's built for small service businesses that depend on local outreach — dental and optometry practices, chiropractic and med-spa clinics, veterinary offices, HVAC, plumbing, pest control, and other home-service providers.
The workflow is straightforward: choose an industry playbook (for example, dental recall or HVAC seasonal promotion), customize the postcard in the visual editor, and import your contacts from a CSV — PostKnock maps the columns automatically. From there it prints your postcards and ships them First-Class through USPS, with no setup fees, minimums, or contracts.
After mail is delivered, PostKnock builds a prioritized call queue for your front desk, complete with industry-specific scripts and one-click outcome logging. Multi-wave sequencing (up to five waves) automatically advances non-responders to the next touchpoint, so postcards and calls reinforce each other over weeks instead of a single send.
Every campaign is measurable: QR-code and URL tracking, delivery confirmation, scan and call-completion metrics, and real-time notifications give you a live view of performance from one dashboard. Deployment is fully cloud-based — nothing to install.
