- Single Sign-On and Active Directory sync are Enterprise only
- Enterprise is quote only, with no published rate, and is positioned for organisations with 100 or more members
- Unlimited auto-join and announcement channels require Enterprise; Starter and Pro get one of each
Klaviyo
- The free plan caps active profiles at 250 and sends at 500 emails a month
- Pricing scales with stored profile count rather than with messages sent, so an unengaged list costs the same as an active one

- Paid tier prices are not published on the pricing page and depend on profile count
