Apple's Mail Privacy Protection (MPP), implemented in September 2021, prevents senders from knowing if a recipient actually opened an email if the recipient is using the native Mail app. It does this by showing all emails in the inbox as opened. This means that your open rate contains verified opens, along with unverified opens. You can read more about this and how open rates work here.
As of November 22, 2023 Action Network tracks your total verified and unverified opens. Verified openers are activists whose emails we can be reasonably sure are being opened by a person, not a machine. Unverified openers are activists where we can't know if machine or human opened the email, likely due to MPP being enabled. Unverified does not mean a person didn't open the email, it just means we cannot know for certain.
You can target emails, mobile messages, and reports based on verified or unverified opens. This means you can include or exclude email openers if they're verified/unverified. At first, everyone on your list will be unverified. It will take a few weeks of emails being sent to the list for Action Network to accurately sort people into verified or unverified openers.
Note that open rates do not represent the performance of your email overall. We recommend using click and action rate to more accurately analyze your email's performance.
For emails sent between July 22, 2022 - November 22, 2023, you'll see your total opens and unverified opens (formerly called machine opens). Emails before this date will show "--" instead of a number of machine opens. This number is not deduplicated per activist. These statistics are mainly for informational purposes.
