The search is very powerful.
Likeliness to Recommend
What differentiates Slack from other similar products?
finding anything in old emails is a nightmare. slack's search is amazing. i can find any message, file, or link from years ago in seconds. it is a searchable archive of your whole team's brain.
What is your favorite aspect of this product?
i love that i can filter my search by person, channel, or date. it is very powerful. it has saved me so many times when i needed to find a specific decision that was made a long time ago.
What do you dislike most about this product?
on the free plan, you can only search the last 10,000 messages. it is very limiting.
What recommendations would you give to someone considering this product?
if you have a good memory, you don't need search. for everyone else, slack's search is a lifesaver.

it is faster than email.

slack is all about speed. it is real-time chat. email is so slow. i can get an answer to a quick question in seconds on slack. this is the biggest difference.
What is your favorite aspect of this product?
i love that i can see when someone is typing. it feels more like a real conversation. using @ mentions to get someone's attention is also great. it has made our team communication so much faster and more efficient.
What do you dislike most about this product?
because it is so fast, people expect you to reply instantly. it can be stressful.
What recommendations would you give to someone considering this product?
if you want to speed up your team's communication, get slack.

threads keep conversations clean.
Likeliness to Recommend
What differentiates Slack from other similar products?
the thread feature is the best. in a busy channel, you can reply to a specific message in a thread. this keeps the main channel clean and easy to read. email replies are a total mess compared to this.
What is your favorite aspect of this product?
i love using threads for detailed discussions. it stops the main channel from getting flooded with a long back-and-forth conversation. i can follow a specific topic without getting distracted by other messages. it is so organized.
What do you dislike most about this product?
sometimes people forget to use threads and the channel becomes messy anyway.
What recommendations would you give to someone considering this product?
teach your team to use threads properly. it is a game changer for organization.
Pros
- Continually Improving Product
