What is an unsubscribe rate?

Your unsubscribe rate is the percentage of recipients who opted out of your emails after a specific campaign. It is calculated as the number of unsubscribes divided by the number of emails delivered.

A normal unsubscribe rate sits below 0.5%. Anything consistently above this is worth paying attention to.

Is a high unsubscribe rate a problem?

An unsubscribe is not the same as a spam complaint. When a guest unsubscribes, they are politely opting out. When they mark your email as spam, they are telling their inbox provider your emails are unwanted which directly damages your sender reputation.

An unsubscribe is a much better outcome than a spam complaint. That said, a high or sudden spike in unsubscribes is a warning signal worth acting on. Left unaddressed, guests who do not unsubscribe will eventually hit the spam button instead.

Common causes of high unsubscribe rates

Sending too frequently If guests receive too many emails in a short period, they will start opting out. Consistency matters more than volume.

Content that does not match expectations If a guest signed up expecting one type of content and received something different, they are likely to unsubscribe. This often happens when venues send to their full contact list regardless of what those guests opted in for.

Emailing a cold or stale list Contacts who have not engaged with your emails for a long time are far more likely to unsubscribe or worse, mark you as spam. Sending to a fresh, opted-in list reduces this risk significantly.

No clear value Promotional-only emails with no genuine offer or relevance to the guest can cause opt-out rates to climb. Guests stay subscribed when they feel the emails are worth reading.

A sudden large send If you have not sent in a while and then blast your full list, expect a higher-than-normal unsubscribe rate. Guests may not remember signing up, or your emails may feel out of nowhere.

What to do

• Make unsubscribing easy. Hiding or obscuring your unsubscribe link does not keep guests on your list as it pushes them toward the spam button. A visible unsubscribe link is both a legal requirement and a deliverability best practice.
• Review your sending frequency. If you are sending more than weekly, consider scaling back and monitoring whether unsubscribes decrease.
• Segment your list. Sending targeted campaigns to engaged segments performs better than sending the same email to everyone. Guests who receive content that is relevant to them are less likely to leave.
• Re-engage before you lose contacts. If a contact has not opened your last few campaigns, send a dedicated re-engagement email before they unsubscribe or go cold.
• Accept that some unsubscribes are healthy. A smaller list of engaged guests who genuinely want to hear from your venue will always outperform a large list of contacts who tolerate your emails at best.

FAQ

Does unsubscribing hurt my sender reputation? Not directly. Inbox providers do not penalise senders for having guests unsubscribe. However, a high unsubscribe rate is often a leading indicator of deeper issues — low engagement, poor list quality, or mismatched expectations — that can affect your reputation if left unaddressed.

What is the difference between an unsubscribe and a spam complaint? An unsubscribe means the guest opted out cleanly. A spam complaint means they reported your email to their inbox provider. Spam complaints are far more damaging to your deliverability than unsubscribes.

A guest unsubscribed but is still receiving my emails. What happened? Check whether they are receiving transactional emails rather than marketing emails. Transactional emails (such as voucher or reward sends) are sent based on guest actions and are not affected by marketing unsubscribes. See our article on transactional and marketing emails for more detail.
