I would like to send weekly messages to a list of users which is updated each week.

Hey @support 5 Racheal from the support engineer team here👋 

If I'm understanding correctly, you are looking to have your workspace pull user data as well as message content from your Excel or Google Sheet, have I got that right? If so, as far as importing message content using the create a message endpoint of our API is going to be your best option there! You can import your users from the following sources: 

CSV

Via Rest API

Mailchimp

Mixpanel

If you are hoping to automatically import user data you would be able to use our REST API and/or our webhooks to write a script or app to do this, however, it would require some dev resources on your end. Before getting started I would suggest reviewing our developer documentation to see the available endpoints as you explore what’s possible.

If you don’t happen to have a developer on hand you could also look into using a 3rd party automation tool, such as like Zapier, instead. It looks like they have a Google Sheets <> Intercom connection:
