How will Google's new spam rate threshold impact email deliverability, especially for B2B senders?

Summary

Google's new spam rate threshold significantly impacts email deliverability, particularly for B2B senders. Non-compliance leads to emails being treated as unwanted, potentially rejected or sent to spam, with diminished chances of mitigation if blocked. Responses to spam issues are expected to be incremental, starting with rate limiting and progressing to blocking. A spam vote rate near 0.3% can already cause deliverability problems, and B2B mail complaint rates are often unknown due to limitations in Google Postmaster Tools, which doesn't fully account for Google Workspace data. Addressing B2B spam requires scrutiny of email address sources and a halt to improper acquisition practices. While the spam rate is assessed over time to minimize the impact of a single bad day, it is recommended to target a complaint rate of <0.1%, especially for high-volume senders. Adapting to new spam thresholds necessitates focusing on authentication, list hygiene, and delivering valuable, solicited content. B2B senders must prioritize list quality and opt-in practices, as complaint rates directly affect inbox placement. Proper email authentication is key to establishing credibility, while engagement metrics like opens and clicks influence deliverability. Sender reputation significantly impacts deliverability, and maintaining clean, engaged subscriber lists is essential. Personalized, targeted cold email strategies are crucial; generic mass emails are more likely to be marked as spam. Prompt and effective handling of complaints is vital, and encouraging subscriber engagement through relevant content, personalization, and A/B testing improves deliverability. Furthermore, updated deliverability changes will impact B2B senders relying on older or less compliant tactics, requiring them to authenticate correctly, manage lists effectively, and ensure their content is wanted. New authentication requirements benefit those already adhering to best practices, but cold emailers must adapt their strategies to avoid being filtered as spam.
