Graymail is a promotional email from a legitimate sender that varies in value to different users. Different from spam, the variance in content and in relevance to users makes it more challenging to filter with rules or policies.
Graymail is a type of email that falls between unwanted spam and desired emails, like a newsletter or marketing alert.
Graymail messages are commercial emails sent in bulk to large mailing lists, and while recipients have opted in to receive messages, they may have done so by accident, or expecting different types of outreach.
Why Graymail Is Challenging
Unlike spam, which comes from unsolicited or deceptive senders, graymail comes from legitimate senders to which the recipient has consented—at least at some point. This makes it difficult to block outright without risking the loss of messages some recipients may actually want.
The challenge is further complicated because what one person considers graymail may be valued by another. Traditional rule-based filters struggle to make this distinction at the individual level.
