Account limit notifications
Plan limits specify the maximum number of clicks per day allowed for any single link. If redirect limits are hit, visitors can still reach destination URL by clicking through an interstitial page. The interstitial is same as our URL Preview page.
Other limits include URLs in one month, total URLs and API requests.
If notifications are enabled, you will receive an alert when any account limit reaches 90%.
Alerts are sent to email addresses you list in Settings > Account > Notifications
