Bulk email limitations explained

Bulk is designed for users who need it for business-critical purposes, e.g. Recruitment consultants emailing individuals applying for a specific job(s), support users needing to update their users, and accounts departments sending invoices.

The danger of giving all users bulk permissions is that this massively increases the risk to the company, the company’s clients and Proofpoint Essentials of a spambot (for example) causing serious IP reputation problems. When a spambot is detected, Proofpoint Essentials will shut down the infected address(es) to eliminate the risk of it causing any problems.

Increasing the bulk limit for all users affectively removes this ability. There are specific third-party programs that are designed for bulk sending, e.g. Constant Contact, MailChimp, and These companies have designed their platform to professional deliver bulk messages. These companies are recommended for services such as sending marketing material like newsletters.

Another recommendation is to set up a custom rule in your exchange outbound rules to send out e-mail for your newsletters and other bulk messages that bypasses the outbound email filtering. This is not a recommended option due to the reasons described above.
