Improve Domain Email Reputation

Our marketing emails are struggling to reach the inbox. Outlook reports a consistently low trust score for my sending domain, so most of our promotional campaigns end up flagged as spam instead of engaging our customers. I need an email-deliverability specialist to diagnose why reputation dipped and implement concrete fixes that boost trust with the major spam filters. An SPF, DKIM, and DMARC checkup, sender-score analysis, list hygiene review, and content best-practice tweaks will likely be part of the work, but I am open to any proven tactic you recommend. The end goal is simple: have future marketing sends consistently hit the primary inbox. Deliverables • Clear audit report outlining every reputation issue discovered • Step-by-step remediation (DNS records, authentication, list cleanup, template adjustments, etc.) implemented or documented for my tech team • Final test campaign showing improved inbox placement and a documented trust-score increase I’ll supply current DNS access, bounce/complaint stats, and recent campaign examples as soon as we start. Show me examples of similar reputation turnarounds you’ve handled, and tell me roughly how long it took to see measurable improvements.
