Bernard was running healthcare outreach at 500,000 emails per month across 20+ sending domains. Security scanners were pre-clicking every tracked link, corrupting all engagement analytics. Spam filters were actively blocking healthcare outreach before reaching any inbox.
Bernard's outbound operation ran healthcare campaigns at significant scale across 20+ sending domains. Two distinct problems were occurring simultaneously. First, enterprise security scanners at healthcare organisations were pre-clicking every tracked link in every email before the recipient saw the message — destroying all click analytics and causing false positive engagement signals. Second, spam filters were actively blocking healthcare-related outreach content before reaching primary inboxes. Both problems were happening across all 20+ domains with no clear prioritisation of which domains to fix first.
Multiple domains with reputation damage from inconsistent send volume across the estate. Some domains were carrying far more than safe daily limits while others were underused. Link tracking patterns were triggering enterprise security proxies specific to healthcare organisations. Content patterns in the email body were flagged by spam filters. No structured domain health monitoring was in place, so damaged domains were continuing to send without detection.
Full audit across all 20+ domains in priority order by reputation damage level. Blacklist clearance for any listed domains. DNS authentication rebuilt where broken. Sending volume redistributed across domains based on health score. Content and link structure reworked to avoid security scanner triggers. Domain health monitoring set up to catch future degradation before it becomes visible in campaign metrics.
All 20+ sending domains pulled and audited simultaneously. DNS records, blacklist status, sender score, and domain age checked for each. Reputation damage ranked by severity.
Domains listed on major blocklists identified. Removal requests submitted. Re-test scheduled post-removal to confirm clearance before returning to active rotation.
Broken SPF records, mismatched DKIM selectors, and missing DMARC policies fixed across all affected domains in priority order.
Sending volume rebalanced across the domain estate based on health score. High-damage domains pulled from rotation or put on controlled warmup ramp. Low-damage domains carrying more load temporarily.
Tracked link format revised to reduce security proxy pre-click rates. Redirect chain simplified. Image tracking replaced with plain-text approach where possible.
Email body content reviewed against known healthcare spam filter triggers. Flagged phrases and formatting patterns adjusted. Test sends run through Mail-Tester before campaign reactivation.
Automated domain health monitoring configured. Weekly blacklist check and sender score review. Alert threshold set to flag any domain approaching reputation risk before it becomes a deliverability issue.
All 20+ domains audited and assigned to repair or maintain status. Sending volume of 500,000 per month stabilised across the full domain estate within 4 to 6 weeks. Bot click false positives eliminated after link structure rework. Domain health monitoring in place to prevent repeat incidents without manual oversight.
500k monthly volume stabilised across 20+ domains. Bot click issue resolved. Monitoring live.30 minutes. No pitch. Walk away with a specific diagnosis and fix plan for your setup.
