Free Bindwise plan offers all the functionality limited to a monthly tracking duration.
Monitoring runs 7 days/mo. Unfortunately, you can't choose these 7 days. After a 14-day free trial, you'll have no service for 23 continuous days, then tracking will be enabled for 7 continuous days. And so on.
Alerts for those 23 inactive days are deleted.
During the 7 days of active monitoring on a free plan, you'll be able to receive up to 50 alerts/day about any business issue that happens in these 7 days.
To remove the limitations of a free plan, upgrade your subscription.
