What does graymail refer to in email marketing?

Graymail refers to emails that individuals have opted in to receive at some point but no longer wish to receive. This term highlights the nuanced category of emails that are not technically spam because the recipient has given consent at some stage. Graymail can lead to low engagement rates, as recipients may ignore these emails or unsubscribe from the mailing list entirely.

By understanding graymail, marketers can focus on maintaining their lists, ensuring content remains relevant to their audience, and managing their sender reputation. This can ultimately improve engagement levels and the effectiveness of their email marketing campaigns. Recognizing graymail enables marketers to refine their strategies and keep their inboxes engaged with content their audience truly values.
