Emails can get blocked or flagged as spam due to various factors that spam filters consider. These filters assess incoming mail based on multiple criteria, including the email's source, reputation, content, and recipient engagement. Different filters may have varying assessment methods, leading to different outcomes.

The reasons for email blocking or flagging include suspicious sources, blacklisted addresses, spammy content, and lack of recipient engagement. To prevent this from happening, it's essential to follow best practices, such as using validated email addresses, avoiding spammy language and links, and ensuring recipients have opted in to receive your emails.
