The consensus from experts, email marketers, and Google's documentation is that the experience of contacting Google's bulk sender form is generally unfulfilling and its effectiveness is questionable. Most report not receiving a response. While some observe improvements in deliverability after a period, causality isn't proven. A strong emphasis is placed on proactively managing sender reputation through authentication (SPF, DKIM, DMARC), list hygiene, engagement metrics, and following Google's bulk sender guidelines. Postmaster Tools is highlighted for monitoring deliverability, but the form itself is largely regarded as a 'black box' or outdated.
