Contacts can unsubscribe from the mailing lists they are subscribed to at any time. This can be done through the unsubscribe link included in the footer of an automation email or a campaign. In this article, you will learn more about unsubscribes that occur from a campaign.
How do unsubscribes work from a campaign?
When a contact unsubscribes from a campaign, the contact will be unsubscribed from all lists to which the campaign was sent, provided that the contact was subscribed to them before. The contact will be unsubscribed from all selected mailing lists because the system cannot determine for which specific list the contact would like to unsubscribe with their opt-out.
For example: you send the campaign to five mailing lists. The sample contact is subscribed to three of these lists. If the contact unsubscribes via the campaign you sent, the contact will be unsubscribed from the three lists. These are the lists to which the campaign was sent and where the sample contact was subscribed. The unsubscribe will not affect the two lists where the contact was not subscribed or other mailing lists.
How can you prevent contacts from unsubscribing from multiple lists?
To prevent your contacts from unsubscribing from multiple lists, it is wise to send campaigns to as few lists as possible. For example, you can also create a list 'all customers'. If all contacts are on one list, you only need to send the campaign to one list. If contacts unsubscribe, they will only unsubscribe from one list, keeping your unsubscribe rate as low as possible.
