How can I validate a domain for Verizon FBL without using postmaster verification emails?

The overwhelming consensus is that bypassing `postmaster@` verification for Verizon FBL is extremely difficult, with no guaranteed alternatives. The primary recommended approaches are to accept its necessity and optimize the handling of these verification emails. Double DKIM signing (using the ESP's domain) might offer a workaround in specific cases, depending on ESP support. Requesting verification emails to `abuse@` is a slightly more plausible alternative, though unlikely. For shared IPs, aligning the 'from' domain with the IP owner's domain or using dedicated IPs are important considerations due to Yahoo's (Verizon's) policies. Proactive measures such as proper email authentication (SPF, DKIM, DMARC), monitoring sender reputation, and maintaining clean email lists are crucial for overall deliverability and can help mitigate the need for frequent FBL verifications. Setting up custom DKIM keys and understanding the FBL setup process are essential for managing email deliverability and sender reputation.

Several strategies can potentially bypass postmaster verification for Verizon FBL setup, though direct alternatives are limited. Double DKIM signing, using the ESP's domain instead of a custom one, is one option. For shared IPs, aligning the 'from' domain with the IP owner's domain, or using dedicated IPs are suggested. Proper email authentication (SPF, DKIM, DMARC) is crucial for sender verification. Actively monitoring sender reputation through tools like Google Postmaster Tools and maintaining clean email lists by removing unengaged subscribers also helps improve deliverability and reduce spam scores. Using a dedicated IP address can further assist in inbox placement.

The dominant advice centers around the near necessity of using `postmaster@` for Verizon FBL verification. Alternatives are limited and often depend on ESP capabilities. Double DKIM signing with the ESP's domain is presented as one possible bypass. Requesting to send verification emails to `abuse@` is slightly more plausible than other non-standard addresses. Fundamentally, validating the legitimacy and interest in FBLs is crucial to prevent hijacking. Custom DKIM records enhance identification and protect reputation, while feedback loops, though often requiring `postmaster@` validation, offer crucial data on spam complaints for list cleaning and overall reputation improvement. Setting up your own DKIM keys is a good step to avoid problems with shared domains. There is the overall sentiment that while some things are difficult, they exist for a reason and trying to change them might be more effort than its worth, and simply catching the verifications emails is an easier process

The documentation emphasizes the importance of understanding the general FBL setup process, including providing necessary information like IP addresses. While not directly bypassing postmaster verification for Verizon FBL, the documentation stresses the importance of DMARC, SPF, and DKIM. These are essential protocols for authenticating your emails. FBLs from ISPs offer insights into spam complaints, which can improve deliverability, and FBLs are a key part of deliverability, even if they do need the `postmaster@` email.
