Summary

When blocked on Verizon and receiving canned responses, a multifaceted approach is necessary. It involves understanding potential reasons from the error messages themselves and leveraging external tools like SenderScore, Talos, and MXToolbox to check IP/domain reputation and blacklists. Ensure proper email authentication (SPF, DKIM, DMARC) and consider gradually warming up new IPs. Proactively monitor your spam rate and feedback loops through Google Postmaster Tools and set up feedback loops with other ISPs. Review your email content for spam triggers and maintain clean email lists. Persistently contact Verizon support for escalation, but also recognize that it may be difficult to get past automated responses. Engage in industry initiatives like whitelisting and proactively monitor your sending reputation across multiple platforms. Finally, adhere to general email deliverability best practices, including list management, authentication, and content optimization.
