Track Opened Emails In Rails

Tracking opened emails is a technique that, if used responsibly, can provide utility to both you and your users.Here a few use cases where it makes sense to me:Appointment updates. If your appointment in a car dealership was rescheduled an email is sent. If the email is not read in the next couple of hours a repeat email can be sent or a CS agent may follow up with a call.Uber-style fulfillment, where contractors are notified of lucrative jobs available to them. If nobody claims a job, a CS agent can go through users who are known not to have read the email.Providing estimates to event organizers how many people are going to show up based a on number of opened emails.
