Summary
Contacting Libero, Virgilio, and Iol admins for whitelisting is best approached by focusing on building a positive sender reputation. This includes implementing proper email authentication (SPF, DKIM, DMARC) with only one SPF record authorizing all sending sources, managing subscriber lists responsibly using double opt-in and segmentation, maintaining low complaint rates, ensuring a clean IP address, and actively monitoring deliverability metrics using tools like Google Postmaster Tools and feedback loops. Direct whitelisting is rare and not always effective. When issues arise, contacting the postmaster of each provider through their abuse reporting address or dedicated postmaster email (support@postmaster.libero.it for Libero) is recommended. Before reaching out, verify sender reputation and blacklist status. Adhering to provider-specific guidelines from Libero and Virgilio, engaging through IOL's support channels, and proactively managing email programs are crucial.
