What is the sender domain and bounce domain?
As the name suggests, sender domain is the domain name used in the email address in the From field of any mail you receive. It helps the recipients identify where the mail came from. For example, in the email address “julius@zylker.com”, the sender domain is “zylker.com.”
Sending mails and suffering from bounces go hand-in-hand. It’s vital that all the bounces you face are routed to a particular domain so that you’ll have an easier time going through these bounces to rectify them. That’s where having a bounce domain comes into picture. It not only tracks the undelivered or bounced mails but also helps in managing the sender reputation. For example, if you have a bounce email address “bounces@zylker.com” the bounce domain is “zylker.com.”
