The countdown module of Splio Message Builder is generating a repeating gif of the timer (1 minute of the countdown). This gif is generated (and so is the start date) when your customers attempt to load the image, so for most of them when they open the email that is containing the countdown. In this case, the countdown reflects perfectly the correct time until the end date.

With iOS15, Apple released a new feature called Mail Privacy Protection. When the user chooses to enable it (40 to 50% adoption rate), Apple’s servers are downloading the image before the user opens the email. Your countdown will be well generated and the customer will be able to see it but the remaining time will be related to when Apple’s servers have downloaded the image, not necessarily when your customer has opened the email.

For most of your customers, the impact is very low and they will not see the difference because most of the users that usually open your emails will do it in the first hour of receiving (or nearly). However, keep in mind that if a user comes back to the email they will have false information (it will be the same image as the first open).
