The Net Emotional Footprint measures high-level user sentiment towards particular product offerings. It aggregates emotional response ratings for various dimensions of the vendor-client relationship and product effectiveness, creating a powerful indicator of overall user feeling toward the vendor and product.
While purchasing decisions shouldn't be based on emotion, it's valuable to know what kind of emotional response the vendor you're considering elicits from their users.

Fast Chats, Faster Decisions.
Likeliness to Recommend
What differentiates Slack from other similar products?
We use it daily to coordinate flash promos, flag stock concerns, and loop sales into website performance shifts in real time. Channels tied to product lines or campaigns keep discussions focused. When something spikes or dips, the right people see it instantly.
What is your favorite aspect of this product?
The real win is how searchable everything is. Past conversations, shared files, quick decisions. All easy to pull up. Integrations also make a difference, pulling alerts from sales and e-commerce systems straight into the flow.
What do you dislike most about this product?
The downside is that without discipline, channels can multiply and attention gets split. It needs clear ownership to stay effective.
What recommendations would you give to someone considering this product?
From a business perspective, Slack has tightened communication and reduced lag between insight and action. I’d recommend it to retail teams that move fast and need clarity without bureaucracy.
