RheeboMail makes it easy for your site visitors to subscribe and unsubscribe from emails. We recommend that you create separate lists for specific events such as newsletter, events or promotions. This way it gives the subscriber flexibility in choosing what to receive from you and gives you a better chance of retaining recipients.
For instance, if you had one email for everything, a person that unsubscribes will not receive any emails from you. If you seperate them, a recipient may choose to unsubscribe from just one type of email.
