Awesome list

This is a great list. May I bring your attention to Helpmonks — http://helpmonks.com?

Helpmonks is the ridiculously easy way to keep your team email organized. Something I’m sure some of your readers will love.

We do have paid accounts, however, Helpmonks has a free account for one shared inbox with three users. Additionally, Helpmonks is free of charge for any open source project or non-profit organization.

Thank you.
