Automation features and user-friendly interface support seamless communication
Slack is very supportive in terms of communication between my colleagues and clients. While working with the reimbursement feature, I found the automation capabilities on Slack to be incredibly useful, allowing me to automate messages for specific dates or times and even to greet someone on their birthday. I haven't specifically used the channel organization feature of Slack, as I am added to channels, but I use it with Airtable, which automates notifications to a specific Slack channel when a user fills out a form on our website. In my experience, Slack is a stable product for communication, and I appreciate its automation features and integration of AI capabilities for enhancing specific functions.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Nowadays, we don't need to visit an HR portal. Our marketing and human resources teams directly share details about birthdays, upcoming events, and important dates in Slack. Whether it's a training event, a company-wide gathering, or a social event, all the information is shared there. This keeps us all updated."
"Its integration with different apps is a great feature."
"When we work with a platform like Slack, we can have one source without merging different document versions."
"I like Slack's notifications. It is more user-friendly and pleasing than Teams."
"In managing releases via Slack channels, one major advantage over Teams is the ability to have threaded discussions, which helps in catching up on relevant discussions without the distraction of interleaved conversations."
"Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks."
"It allows to facilitate communication, allowing us to create channels for updates, file sharing, and photo sharing within our team profiles."
"Yammer is useful since it is a product you can easily integrate into our system since Microsoft supports it."

Cons

"It could be more stable than one of its competitors."
"From my perspective, a disadvantage of Slack compared to Teams is that connecting between the apps can be a bit difficult."
"The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM."
"I would like the text in chat to be more customizable."
"It would be better if Slack had a 'select all' option to delete all the files."
"Slack tends to crash once a month."
"Slack's screen sharing might also add the remote control feature, which is not there."

"It looks slightly less clean on Chrome compared to Microsoft Edge, but it's a minor difference. There is room for improvement in user experience, like positions of elements."
"Yammer should be able to integrate with Microsoft products, such as Outlook."
"Users need to be in the Acting Directory to exploit the features."
"Sometimes, we lose access to the solution for unknown reasons."
"I would rate the stability of Yammer as six out of ten."
