Pros

“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

“What I most like about Slack are the video call feature (Huddle) and screen-recording feature (which also allows you to record audio and camera with it).”

James W.

Salesforce Administrator

Pros

“Features like creating large groups, sharing documents, and the Web/Desktop version make it an excellent tool for quick team coordination and daily personal check-ins.”

Ravindra S.

Owner

“WhatsApp is a reliable everyday platform to connect with family, friends or colleagues by providing the features like messaging, voice notes, audio and video calls, group calls, sharing and receiving photos and videos.”

Prachi D.

Administrative

“instant communication that's familiar to most of my customers, WhatsApp Business with built-in product catalog, free calls and messages worldwide, handy status updates for informal marketing.”

Nicole T.

Event Marketing and Operations

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 only time I get frustrated with it is when I need to invite partners (from external companies) into our workspace for targeted deal collaboration. When those folks come from organizations stuck with Teams, it's not easy to get them to adopt it for a limited time, even though it's easy enough to add them to the dedicated Slack workspace.”

Alicia R.

Director, Business Development

“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.”

Enish S.

Business Administrator

Cons

“You can't sort conversations by order status or tag them as paid versus pending, so I end up scrolling back through dozens of chats to find that one customer who wanted logo placement adjusted.”

Ana N.

Founder

“because WhatsApp heavily compresses shared photos and videos, we cannot use the platform to send high-quality media assets for final technical approval.”

Jessee G.

Director of Media

“Although I understand from a privacy and security perspective that logging into multiple devices can jeopardise that set-up, but once a device has been set as trusted, if I were to lose my phone, being unable to access WhatsApp on my computer is frustrating.”
