Accounts Payable

The best features of Slack are its innovative interface and easy to use features. Slack makes it simple, and even kind of fun, to communicate with your coworkers quickly.

Student

While they are only visible to me, I am always worried that I accidentally posted something wrong.

Technical account manager

I like the different slack channels for various departments, tech-support, team, individual messaging, and celebrating my teams successes or helping each other out with account  challenges.

Manager of Data Integration

Slack has been a winner for me no matter which role I am filling. Teams adopt it quickly it's easy to use, easy to set up, and has abundant opportunities for integrations.

Executive Assistant

I disliked the inability to make a public group "private" after it's creation. Would occasionally lag and my.

Director

Slack has been the best decision made as far as intra-company communications platform, and also project friendly. Sharing of files and easy display help save time and effort.

Senior Software Engineer

Super easy set up, effortless onboarding, and great pricing plan for small groups. It has strong search functionality and intuitive threading.

Customer Success Manager

I hate hate hate how often I struggle with using the video share and audio when someone calls me on slack. It almost never works for me.

Entrepreneur

I like the chat option because I can send and receive real-time messages and chat with my team directly and the Slack messaging app is very powerful and amazing.

Logistics / dispatcher

You can have fun and customize. For example: We have a 'Jokes' channel that the slack bot will tell you jokes if you ask 'bot tell me a dad joke'- It's amazing.

It's super easy to stay connected with all of your colleagues. The desktop app is very nice.

It combines the depth you get from email communications with the efficiency of texting. And, if you do it right it is great for building a good, fun company culture.

Admissions Intern

In addition, files are saved and archived for easy access. I also liked the ease of use and ability to collaborate with anyone in your organization.

Research Analyst

They found it awkward that everything was a chat in Slack and uncomfortable with sending out a message that may "bother" others for small issues, and reverted to email, even with consistent reminders.

Head of Marketing 

I love the giphy option, some of the gif’s are hilarious. Also, some of the integrations are very useful - google calendar especially.

SVP Operations

I like the ability to quickly reach out to someone with a quick question vs. email. Having groups is also useful for the same reason of quickly updating a broader, interested audience.

Associate

Slack was a great platform that made the workplace feel like a community. Its user friendly interface allowed everyone to come together and share messages of high importance.

Customer Insights Specialist

OVerall Slack is very good and highly recommended if your budget allows it.

Best Communication Tool - Hands Down

Alberto O.:                                            Hey everybody. My name's Alberto. I'm the founder and president of an online tutoring service. And we switched originally from WhatsApp over to Slack. And for more reviews like this, click below.
                                                       So both Slack and WhatsApp really come down to solving the problem of an internal communication within your team. That's really what we used it for. Primarily, we did use WhatsApp originally and then we noticed that with our scaling and everything that we needed to do integrating wise, we moved over to Slack.
                                                       So Slack is really best to keep all your communications within one central location. Usually we were using WhatsApp. We were also using email and other kind of communication applications. Slack is really the all-to go-to one that we started using once we started to integrate with other applications and marketing applications that we used before, something that WhatsApp really wasn't capable of doing.
                                                       WhatsApp is truly best for just a much simpler communication within a team or with someone else individually within your team. It does allow you to create groups, but other than that, there's really no automations that you can build from. There's really nothing outside of the box between a typical text messaging service.
                                                       So with WhatsApp, it's truly as easy as it gets. You basically just download the application, whether the WhatsApp or the WhatsApp Business application, you input your phone number, you receive a verification code and you're all set. Then you can upload your contacts and start talking to whoever you would like within your contacts. Slack is a little bit more hands on, but at the end of the day, very streamlined. You just create an account. You invite your whole organization through your domain name or some type of company name, and then you start to add everyone on your team, divide them into groups, if you would wish. And then if you would like to get a little bit more technical, although it's very easy as well, you can integrate some applications that you use as well, very automated through their own build software.
                                                       So for us, top consideration was really price. Originally, we used WhatsApp as it's free and apparently will always be free, but it is very limited when it comes to a scaling organization. Slack does have a free plan and we did go ahead and move forward with it and it really gave us everything that we did need. The only thing that it did not give us was historical messages, more than 10,000. Once we reached that limit, then we did progress to move forward towards a paid subscription.

Graduate Research Assistant

That it is owned and exploited by Facebook. The whole confusion of allowing FB to purchase this software, along with getting access to the data from it, leaves a bad taste in my mouth.

PHD, IIT Mumbai

The other worst function is broadcast. Because of this feature people are using it for unwanted advertisement purposes.

Web designer

And its integration with the web is also wonderful because there we do not need to load the file on the cell phone to then share with customers, just log on to the computer and share.

Freelancer and Digital Marketer

Our Business WhatsApp was banned with no prior notice and no reason to ban. Now whenever we try to register they tell us to contact support as this phone number is banned.

Software Engineer

The best feature about WhatsApp, its chatting is very responsive and reliable. We can share pictures, videos, files attachments, music, audio notes, documents, location contact easily and rapidly.

It is very easy to use, it makes international communication very easy, works perfectly for work communication, the business option is great for communication with clients.

Business owner

During bad weather, the connection was affected. But when using other services I had the same or worse issues.

Office manager 

WhatsApp is amazing you can text and call for free all of the world, you can send videos and photos and you can make group calls as well. It’s also great for FaceTime like videos.

I have been using this messenger for more than 8 years now and its hands down the most secure and easy to use messenger with great group admin functionalities and the best chat features.

SR. Team Lead US IT Recruitment

A time was there where every single text had a different procedure but whats-app has given it new heights. The idea was brilliant and UI and UX are been also very good and easy to access.
