Email unsubscribe is one of the most dreadful things for any email marketer. After all the hard work you put into a campaign, it is particularly annoying to get your emails unsubscribed.
According to Mailjet, if your unsubscribe rate is below 1%, you are said to be within the industry norm. However, emails sent to new lists—to subscribers who have not received an email from you before—are not included in this calculation because they usually have more unsubscribes. Your industry also influences the number of unsubscribes you get. An agreeable unsubscribe rate is below 0.5%, and you should work on creating better emails if your unsubscribe rate exceeds that.
