Recent Game Changing Innovations

5.0 2 months ago New

Pros:

I've been a Slack user since the beginning, and now there are many Slack competitors on the scene. Over the years we've tried tools like Teams, as we are O365 users, however, we keep being driven back to Slack as it just works. Slack has everything you could need for a team collaboration and communication platform, and with its continued innovation, it's truly becoming our digital HQ.The Salesforce acquisition of Slack has proved to be a good thing, and I'm excited to see the innovation that will continue to come from this relationship.Slack went through a period of time where innovation seemed to slow and we were burdened by buggy features like Slack calling. In the past year their pace of innovation has stepped up, and we've benefited the most from Slack Huddles, which are reliable and feel more personalized than Zoom. Their roadmap also looks exciting with features like Canvas coming down the pipeline, a much-needed addition to Slack.

Cons:

I don't like how it's difficult to create long-form posts/messages that include multiple images. The images/files are all attached at the bottom of your post, and if you want to follow a structure like text, image, text images, you have to create multiple back-to-back posts. Hopefully the Slack Canvas feature will solve this pain point.

Discussing about pros and cons with features.

4.0 2 months ago New

Comments: I am using Slack for the last 3 years in my daily life. It helps in my daily usage of communicating with my firm colleagues and work partner. It helps me in different in this period like audio calls, messaging, and sharing documents and files. The magic link feature is amazing. I think only a few apps or software have these types of features.

Pros:

I feel the most marvelous features in Slack are magic links, a separate channel, real-time messages, and notifications. Real-time messages and notification help to easily communicate with co-workers. Magic link is an easy way to access your account without email and password. It is faster as well and sometimes it is not necessary to remind email passwords. A separate channel is a secure way to access or have project discussions. It is also good in security ways by it have own URL to join its particular channel to those who are authorized. Due to this slack brings people together to work as one unified team

Cons:

Slack is a messaging app for businesses. One thing about being dissatisfied with slack conversations get deleted after 14 days, so if we sent something important within a channel it will erase so this feature kept me having difficulties at some sort of times.

Alternatives Considered: Microsoft Teams

Reasons for Switching to Slack: If I have to purchase a product besides slack, I will choose Microsoft. Because of Storage space, Microsoft teams have 1 TB of space in the basic package but slack has 1 TB in Enterprise. We have to agree that Microsoft has well storage than slack. And another reason is audio sound of Microsoft in a good n comparison to slack.

It's a great Communication tool and the pricing is fair!

5.0 3 months ago

Comments: We felt that we made the right move by switching to this pro tool. Our communications it's very effective, and there is no mistake in mixing private or personal communications. This helped our team to stay focused and always reply in business mode.

Pros:

We are a marketing agency and have several types of contracts and clients who love fast communications and avoid long email threads. We cannot live without it.

Cons:

We are glad that restrictions for free accounts were removed, which allow new adopters to get to know the tool better and incorporate it into their daily activities.

Alternatives Considered: Workplace from Meta and Google Workspace

Reasons for Choosing Slack: Management was becoming chaotic.

Switched From: Google Chat

Reasons for Switching to Slack: Because having an independent communication application with no need to have an opened browser tab was a great choice. Also, the versatility to move between workspaces is a must.

Slack is perfect for cooperating with your team, for conversations and for creating groups

4.0 2 months ago New

Pros:

You can create groups per project or issues with all relevant people and you can share documents, images and everything really simple. There are icons and emojis which are funny and the notifications are very well integrated and help distinguish the important from the not relevant.

Cons:

Video-calling and audio-calling are just not working well and slack for cell phone does not update really well and there are some conversations that you can miss.
