Email providers limit the number of messages you can send within a 24 hour period. (e.g. Gmail: 500, G Suite: 2,000, Outlook: 1,500). Adjusting your daily sending limit will prevent your emails from being delayed to send and also lower the risk of your email being flagged or blocked by your provider.
Step 1 Click on Account, in the navigation bar, and select Account Settings.
Step 2 Click on Email Integration.
Step 3 Under the email settings section, enter your daily sending limit and click Save.
