Spike is an amazing team comms platform. Imagine Slack but inside your email, & with everyone you need - team members, clients and vendors too! Our team loves Spike!
My company started using Spike a year ago & the team feels like it’s vastly improved our productivity. It’s amazing to not have to switch back & forth between a million apps!
“I have the whole firm using Spike for its chat interface and super fast features, and I even got some of my clients on it. They love how easy it is to communicate.”
I had something like 90K unread emails before switching to @SpikeNowHQ. I’m down to just 2K emails. Inbox 0, here I come!
“Spike improved workflow between our teams and clients since they had a collaborative workspace. The entire project history & needed files in one place.”
"I chose Spike because it quickly solved my biggest problem—the overwhelming feeling that there are more emails than time in the universe."
One of the best mail tools. Very simple interface, and very useful tools for daily to-dos.
