How do I deal with a Suomispam blacklist listing affecting my email deliverability?

Key findings

• Limited impact: Suomispam is often considered to have a limited impact on general email deliverability compared to larger, international blocklists. Its primary influence is likely within Finland or with specific Nordic recipients.
• Customer perception: Clients or customers might perceive any blacklist listing as highly significant, even if its actual impact on deliverability is negligible. This can lead to unnecessary alarm and pressure for delisting.
• Cause of listing: Suomispam may list IPs due to spamvertising activities or other abuse. Identifying and rectifying the root cause is the first step toward potential delisting, though their policies on expiration can be strict.
• Shared hosting: Sometimes, a listing might be for a shared hosting environment, meaning your specific domain or IP isn't the direct target. This confusion can arise from certain online blocklist checking tools.

Key considerations

• Verify impact: Before acting, verify if the Suomispam listing is genuinely causing email bounces or deliverability issues. Check your bounce logs for references to the blocklist. Learn how to assess the impact of an unknown email blacklist.
• Educate stakeholders: Help customers understand that not all blocklists carry the same weight. Explain the nuances of how email blacklists work and their varying influence on deliverability.
• Review sending practices: Ensure your sending practices are clean and compliant. This includes maintaining a healthy sender reputation and avoiding activities that could lead to spam complaints.
• Consult Suomispam's policy: Review the official Suomispam blog for their policies and frequently asked questions regarding listings and delisting processes. This can provide direct guidance on what steps, if any, are viable.

Key opinions

• Focus on actual impact: Marketers frequently advise that the first step is to confirm if a blacklist listing, like Suomispam, is actually causing deliverability issues (e.g., through bounce messages) before taking action.
• Manage client expectations: Clients often overreact to any blacklist mention. Marketers need to educate them on the varying impact of different blocklists and emphasize that not all listings are equally critical.
• Ignore if no impact: If a listing isn't causing measurable bounces or affecting campaign performance, many marketers opt to ignore it to avoid expending resources on non-critical issues.
• Blame RBL checkers: Some marketers point to general RBL checking sites for creating unnecessary panic by listing IPs without providing sufficient context on the blocklist's actual relevance or usage.

Key considerations

• Data-driven discussions: Arm yourself with deliverability data (bounce rates, inbox placement metrics) to show clients the actual impact, or lack thereof, of a Suomispam listing. This can help you understand why your emails might be failing.
• Targeted audience: Consider if your target audience for affected campaigns includes a significant number of Finnish recipients. If not, the impact of a regional blacklist may be minimal.
• Preventive measures: Continuously monitor and refine your email sending practices to minimize the risk of being listed on any blocklist, focusing on recipient engagement and list hygiene.
• Communicate clearly: Be transparent with clients about the nature of the blacklist and the likely, or unlikely, effect on their deliverability. This proactive communication builds trust.

Key opinions

• Verify impact first: Experts strongly recommend checking for actual deliverability issues, such as specific bounce messages referencing Suomispam, before undertaking delisting efforts.
• Not all lists are equal: It's a common expert opinion that many less-utilized blacklists, including Suomispam, have minimal real-world impact on most senders' deliverability.
• Regional relevance: The impact of Suomispam might be localized, affecting mail to Finnish recipients more significantly than broader audiences. Consider if your customer is sending mail in Finnish, as this blocklist is regionally focused.
• Difficult engagement: Some experts have found Suomispam difficult to engage with, noting that they may not expire listings, leading to persistent (though low-impact) listings.
• Misleading tools: Online RBL checking sites often provide incomplete context, leading to false alarms about listings on less critical blocklists.

Key considerations

• Prioritize major blacklists: Focus your resources on addressing listings on widely-used blacklists that have a significant impact on your overall deliverability. Learn more about real-time blackhole lists (RBLs).
• Understand UCEPROTECT: While distinct, discussions around Suomispam often parallel UCEPROTECT, another blacklist whose impact can be disproportionately perceived. Understanding UCEPROTECT's impact can provide helpful context.
• Data collection: Collect data on actual bounce messages and deliverability rates before committing to delisting requests for minor blacklists.
• Proactive hygiene: Ensure robust email hygiene practices to prevent future listings on any blacklist, focusing on consent, engagement, and low complaint rates.

Key findings

• Listing criteria: Suomispam explicitly states that they list 'spamvertized sites' and that for delisting, the reason for the listing must be removed.
• Misleading lookups: Their FAQ warns against lookup sites that mix up shared hosting, incorrectly claiming a domain is listed when only another entity on the same host is. They do not suggest filtering based on sender domain IP DNSBL lookups.
• Experimental nature: The Suomispam blog describes their email blacklist (ebl.suomispam.net) as an 'experimental blacklist' designed to cover specific spam issues, implying a targeted rather than broad application.
• DNS records: General documentation (e.g., Leaseweb) suggests that additional DNS records, like PTR records, can help decrease the chance of being listed on a blacklist, emphasizing proactive DNS configuration.

Key considerations

• Understand listing type: Ascertain whether the listing is for your specific domain or IP, or if it's a shared hosting issue that might not directly impact your sending. This helps to understand the difference between a blacklist and a blocklist.
• Address root cause: If your IP or domain is listed for spamvertising, you must stop the activity and prove it has ceased before any delisting is possible.
• Review authentication: Beyond PTR records, ensure your SPF, DKIM, and DMARC records are correctly configured to establish sender legitimacy and boost email deliverability rates.
• Official sources: Always refer to the official documentation of Suomispam for the most accurate and up-to-date information regarding their policies.
