This is a KILLER feature.
Even though I have not used HEY’s implementation of this feature (I’m still waiting for my invitation), I’ve use a similar feature daily in another email/workflow SaaS. At my company, Basis 365 Accounting, we use Karbon, a workflow management software that allows our team to leave notes on email threads. Again, it is a KILLER feature because it allows us to collaborate with each other to coordinate a response or seek clarity without cluttering up our inboxes with forwarded emails.
When HEY brings this feature to the business version HEY later this year, I guarantee that it will be your favorite feature.
This one feature by itself, is almost worth the $99/year price point, but HEY offers up so much more that justifies the price. As a point of comparison, we pay about $70 per user per month for Karbon.
This sounds crazy to say in 2020, but I’m genuinely excited about email again and I’m pounding the refresh button frequently just to see if the invitation has landed in my mailbox.
