Independent research methodology

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.

Pros

“Constant Contact helped simplify email marketing and communication with customers by centralizing contact lists, campaign creation, scheduling, and reporting into one platform.”

Bradley R.

IT Director

“It provides an intuitive platform for creating professional email campaigns, managing contact lists, and tracking campaign performance without a steep learning curve.”

Stacy S.

Sales Marketing Coordinator

“It handles the practical machinery of email marketing: contact storage, list management, templates, campaign creation, sending, and basic reporting, without turning every campaign into an engineering project.”

James G.

Senior Manager, Infrastructure Engineering

Pros

“The process is simple and you can create good looking call to actions for free. If you want to get fancy and really make your CTA "pop" and have more access to features, you can pay for Sumo. As my businesses continue to grow, I will likely end up paying for those extra features on Sumo.”

John T.

Owner

“Sumo is an excellent tool to connect your email marketing to your website and design custom call to actions.”

John T.

Owner

“Seems like sumo integrates a lot of services but all are third party services, like sendfox for sending emails.”

Monica M.

Dott.ssa

Cons

“You can't resize images within blocks, for example, and when you create a new block yourself, you can't copy and paste them into a new template or save them as a content block for reuse.”

Jill R.

Founder, Owner

“Some advanced automation features lack flexibility compared to other solutions on the market, and customer support sometimes responds with a bit of a long delay.”

Mike L.

Global Head of Product Development

“Some of the automation and advanced segmentation features are not as deep as some higher-end marketing platforms.”

Bradley R.

IT Director

Cons

“some features hidden behind paywall- can suffer from option paralysis”

John T.

Owner

“The interface leaves a bit to be desired. ”
