Pros

“It also has very powerful search functionality, which we used to drive a lot of automation and reporting for sales and service managers, first through Zapier and now through Close itself as well as they build out more internal automation triggers.”

Jackson E.

Sales Team Lead

“They handle lead pages with lots of activities and notes really well, allowing you to filter down by activity, customer, employee, timeframe, or text searching.”

Jackson E.

Sales Team Lead

“The trial period felt a bit short, especially for teams that are evaluating multiple tools and need time to fully explore all the features.”

Mehmet A.

Business Development Manager

Pros

“However, managing constant notifications can be overwhelming at times, and finding older messages in a busy channel can be tricky. While it improves team connectivity, the volume of communication can become distracting, making it essential to manage notifications effectively for a smoother experience.”

Arthi R.

Engineer

“Channels help keep discussions organized by project or department, file sharing is seamless, notifications can be customized to reduce distractions, and the powerful search feature makes it easy to retrieve older conversations.”

Emilia W.

Network Support Coordinator

“The intuitive interface, reliable performance, and wide range of integrations have helped streamline our daily workflows and improve productivity. While there are occasional challenges with managing large volumes of messages and notifications, the benefits far outweigh these minor drawbacks.”

Andrea L.

Innovation Manager

Cons

“They also have one limit that hurts automated workflows: you can only trigger them on a small subset of what their search tool allows you to look for.”

Jackson E.

Sales Team Lead

“So if a new lead calls in to your agency/store, and if the call ends and the lead isn't added, then the call's number/history is lost in the ether. If you've ever onboarded new employees, you know procedures like this won't be followed all the time.”

Jonathan L.

Insurance Agent

“Features are clearly targeting the saas sales segment, which wasn't helpful for my agency which essentially is a retail business model.”

Jonathan L.

Insurance Agent

Cons

“Notification management can also be challenging in active workspaces, leading to information overload if not carefully configured. While Slack offers powerful search capabilities, finding older conversations or specific files is not always as intuitive as it could be.”

Cristiano F.

Consultant

“The lack of proper conditional logic (if/then branching) is frustrating. If you want to build complex, multi-step flows with different outcomes based on user input, the native builder just can't handle it.”

Denis M.

Recruiter

“Notifications can become overwhelming fast if you don't take time to configure them properly, and most people don't — which leads to either constant pinging or people muting everything and missing important messages.”
