Mail Privacy Protection for Apple Mail
Apple iOS 15 and Mac OS Monterey come with a new setting called Mail Privacy Protection for Apple Mail.
With this setting enabled it's not possible to tell whether, where or when an email was opened because the tracking image that open tracking relies on (a small, transparent pixel that's not visible for contacts) is preloaded even if contacts don't actually their emails.
This results in unreliable open tracking for your contacts who use Apple Mail to read their emails with Mail Privacy Protection enabled.
Delivery of emails and click tracking are not affected.
Impact on your Envoke account
Email campaign reports
Open rates in email campaign reports may be over inflated depending on how many contacts on your list use Apple Mail with the Apple Mail Privacy Protection enabled.
Since AB testing is based on email opens, its results will be less reliable. This depends on the number of contacts on your list who use Apple Mail with the Apple Mail Privacy Protection enabled.
When you filter your list for campaign activity using "opened" or "didn't open" as a condition the results may be inaccurate - again, depending on how many contacts on your list use Apple Mail with the Apple Mail Privacy Protection enabled.
Re-sending emails to non openers
This in turn affects who will receive your email if you re-send it to anyone who didn't open the original.
