What's the best way to schedule meetings?

It depends on your use case. Calendly is the best tool for scheduling a meeting with groups of people. Tell it what dates/times you're available, how much time (e.g. 30 minutes) you have for each meeting, and send a link to the appropriate people. They can select a slot and Calendly will add it to your calendar immediately. This tool isn't ideal for scheduling ad-hoc meetings via email though. Clara or x.ai are better for that.

Mixmax is an awesome gmail plugin for enhancing your inbox. They recently launched a fantastic meeting scheduling feature.
