Misclassification happens due to reputation, content, authentication alignment, or engagement signals.
Junk Mail Misclassification is when legitimate emails end up in spam. Root causes usually include poor domain reputation, sudden volume spikes, misaligned authentication, or sending to unengaged lists. Content can contribute, but it’s rarely the only factor. A good deliverability workflow includes monitoring bounces and complaints, warming properly, cleaning lists, and verifying SPF/DKIM/DMARC alignment.
