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

“It's a reliable and easy-to-use email marketing tool that integrates seamlessly with Gmail, making it simple to create, personalize, schedule, and track campaigns without switching platforms.”

Saksham K.

Marketing manager

“It makes email outreach much easier by allowing me to manage campaigns directly from Gmail, schedule emails, track open rates, and automate follow-ups.”

Karthikeya S.

Admin

“I was able to send over 300 emails and landed an agent along with 250 emails for a campaign pitch and allowed me to make each email individualized.”

Jackie P.

Model and Creative Director

Pros

“The targeting options are flexible (UTMs, query parameters, device, etc.), and it was straightforward to set up a homepage split test without needing a developer.”

Dallin C.

“I am just getting started with Personizely, but I am super impressed with the customer service.”

Bonnie C.

Founder

“The widgets looks great, are customizable and the customer support is great.”

Adinde R.

Cofounder

Cons

“The sequence logic is less sophisticated than what I had access to in Intercom Series previously, but that's an unfair comparison given the price difference.”

Rene B.

Partner

“There are limitations in email template customization, a potential learning curve due to its feature-rich interface, deliverability issues related to its reliance on Gmail's infrastructure, and a lack of built-in CRM functionalities”

Joseph C.

Director of Operations

“No matter what tool you use, failing to warm up your domain and validate your email list will ruin your sender reputation.”

Narayan S.

Digital Marketing Consultant

Cons

“slightly more expensive monthly subscription”
