Summary
Successfully contacting Optonline postmasters about email deliverability issues is generally difficult and often unsuccessful. Instead, experts and marketers recommend focusing on building and maintaining a strong sender reputation. This involves implementing email authentication protocols (SPF, DKIM, DMARC) to prevent spoofing, maintaining a clean email list through regular hygiene practices (removing unengaged subscribers and managing unsubscribes), and consistently delivering high-quality, engaging content. Monitoring sender reputation using tools such as Google Postmaster Tools and Microsoft SNDS is also crucial for identifying and addressing any deliverability issues. If blacklisted, follow the specific removal process for each blacklist. Consider contacting Cloudmark, as Optimum domains use their services. Gradually warm up new IP addresses to establish a positive sending history. Having a readily accessible abuse contact for reporting issues is also advised.
