Maintaining a good reputation at Microsoft, in order to have emails delivered to the inbox has been getting progressively harder over time, as their spam filters continue to evolve.
Over the past week, across the email industry, it has been reported that a big change has been seen in Microsoft’s filtering leading to much higher spam placement, and delays to emails being delivered for many senders.
This comes at a time when many retailers are already struggling to continue to drive high levels of engagement. The impact of the economic environment is leading to consumers being more price-conscious and wary with spending. As a result, customer loyalty is weakening as many consumers experiment with new brands for the first time, something we also saw at the start of Covid, during Peak.
It is currently unclear if these changes are temporary (following Microsoft having to fix an issue with their spam filters failing in February) or if this is a permanent change that is now catching out many businesses. What is clear, is that even if the current state of Microsoft filtering is temporary they will only continue to make it harder for mail to reach the inbox.

Using this data, you can start to build a reputation repair plan in which you reduce sending volumes to Microsoft, targeting only your most recently engaged contacts and over time building the audience back up. As part of this, you will also need to establish a benchmark open rate for good performance. Whilst opens can no longer be used as a direct measure of contact engagement, they are still useful as a proxy for placement (as in most cases pre-fetching only happens when the email is delivered to the inbox, not the spam folder).
