Office Hours for Your Customers

Hey everyone! 

I'm looking to host "office hours" for our customers and create more of a community and engage customers on a massive scale vs 1-on-1, especially our SMB and tech touch customers.

If you've done this before, how have you gone about doing this (successfully)?

Here's what I'm thinking so far:

• Mass email to key stakeholders with Google Survey linked asking for their areas of interests (e.g. Specific best practices on X problem, feature functionality, connecting with other customers)
• Once I capture their interests, then send calendar invites & Zoom info to customers of respective interested topics

What I've done before:

• In-app product messaging announcing office hours one week in advance (topical office hours)
  • Result: ~Medium to high registration, but low attendance

Also - how do you get new, fresh ideas for topics?

Would love to hear from you!
