SNDS showing Yellow

Microsoft's new requirements cover the technical components of setting up authentication (SPF, DKIM, and DMARC), but keep in mind that there’s more to your deliverability reputation than checking technical setup boxes. According to Microsoft’s SNDS filter results, Yellow encompasses a wide range of “10% < spam < 90%”. If you’re consistently finding Yellow and Red results in SNDS, you will want to review best practices for sending to ensure your audience is actually engaged with and want to receive your mail.
