Don't worry - Slack notifications can be switched on and off at any time in the Slack integration settings page to limit noise from any notifications you don't find helpful.
Our goal with Ramp's Slack integration is to help you cut down on the number of emails your team receives because business activity alerts are sent to Slack channels not to individual users. We are putting the most relevant information about transactions, missing receipts, and statements all in one place for you to manage your finances as a team rather than as individuals.
