You can connect your Lattice account directly to Slack. This will allow you to bypass emails and have all reminders, updates, and notifications sent directly to your Slackbot.
Head to Settings by clicking on your name in the top right corner and select 'Settings'. Scroll down to Integrations and click 'Add to Slack'.
Assuming you are already logged into your organization's Slack team, simply click Authorize and you will be set up.
Note: If for any reason you need to change your Slack team, you can do this in the authorization module.
