ECR (Email Collection Rate) It is extremely important for hotels to keep track of their Email Collection Rate (ECR) because if you have no emails, how can you contact guests for feedback or other marketing initiatives? ECR is the total number of valid emails a hotel obtains divided by the total number of checkouts.

It can be a valuable KPI, not only to monitor performance over time, but also to set objectives for staff. Get the full story at ReviewPro
