In terms of return on investment, I think it was okay. We were pretty satisfied with it, although there could have been improvements, especially in terms of pricing. But compared to the alternative of using Gmail, we found Slack to be more efficient in organizing content and information.

It was more time efficient and helped you save time compared to writing emails. It was faster than writing emails, but the ability to organize content and information properly is what I appreciated the most.

I would put Slack around seven out of ten,  in terms of return on investment.

The product is worth its money. 

Our ROI is approximately 40%.
