Email providers are increasingly making it easier for their customers to stop receiving your newsletters and other subscriber emails. In Gmail, when a subscriber hasn’t opened any email from the sender after 30 days, a notice pops up asking them if they want to unsubscribe.
“Unsubscribe from [newsletter name]? You haven’t opened any emails from this sender in the last month,” it reads. The subscriber can choose “no thanks” or “unsubscribe.”
