Bulk Folder

What is it?

What is it?

The "Bulk Folder," also called the spam or junk folder, is a designated folder within email clients where emails suspected of being unsolicited or spam are automatically filtered. Emails landing in the bulk folder bypass the recipient's primary inbox, significantly reducing the likelihood of being seen or opened by the recipient. This makes managing email deliverability and maintaining a good sender reputation essential for email marketers.
