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.

Cons

“The marketing campaign features are not as advanced as some dedicated email marketing platforms.”

Cons

“I cannot scroll down on my MacBook to see the complete screen material. And though there are quite a bit more templates, they are very basic visually. ”

KIMBERLY E.
