Email Deliverability Expert | Fix Spam & Inbox Placement

Are your emails landing in spam, disappearing entirely, or getting inconsistent reply rates? I help businesses diagnose and fix email deliverability problems across cold outreach, email marketing, and day-to-day business email. My work covers email infrastructure, DNS configuration, sender authentication, domain reputation, inbox placement, migrations, and campaign operations. I work with Google Workspace, Microsoft 365, Apollo, Instantly, Smartlead, GoHighLevel, HubSpot, ActiveCampaign, Brevo, SendGrid, Mailgun, Klaviyo, Lemlist, Kit, and other email platforms. Clients typically hire me for: • Email deliverability audits and troubleshooting • SPF, DKIM, DMARC, MX, BIMI, MTA-STS, and TLS-RPT • Gmail, Google Workspace, Outlook, and Microsoft 365 delivery issues • Cold email infrastructure setup and repair • Domain and subdomain strategy • Dedicated sending domains and tracking domains • Domain reputation and blacklist monitoring • Inbox placement and seed testing • Email header analysis • Mailbox provisioning and warm-up planning • Google Workspace and Microsoft 365 migrations • SendGrid, Mailgun, Brevo, and SMTP configuration • Apollo, Instantly, Smartlead, Lemlist, and GoHighLevel setup • Campaign sending limits, sequencing, and deliverability monitoring • List quality, bounce reduction, and sending behavior reviews My process starts with a complete audit of your sending environment. I review DNS, SPF, DKIM, DMARC alignment, MX routing, message headers, tracking configuration, inbox placement, domain reputation, sending patterns, list quality, and platform settings. From there, I identify the actual cause of the problem. Poor deliverability is often caused by several issues working together, such as authentication gaps, damaged domain reputation, aggressive sending volume, poor list quality, shared infrastructure, tracking configuration, or mailbox provider filtering. You’ll receive a clear resolution plan based on your setup. I can then implement the fixes directly, work alongside your IT team, or walk you through the changes on a live call. I also build outbound email infrastructure from the ground up, including: • Sending domain and subdomain architecture • DNS and email authentication • Google Workspace or Microsoft 365 mailboxes • SMTP and sending platform connections • Inbox provisioning and warm-up schedules • Campaign limits and volume ramp plans • Tracking domain configuration • Deliverability monitoring and documentation I’ve supported more than 100 client campaigns across SaaS, healthcare, financial services, compliance, eCommerce, real estate, and service businesses. My experience includes deliverability troubleshooting, email migrations, cold outreach infrastructure, marketing automation, prospecting workflows, and campaign operations. Platforms and tools I work with include: Google Workspace, Microsoft 365, Exchange Online, Apollo, Instantly, Smartlead, Lemlist, GoHighLevel, HubSpot, ActiveCampaign, Brevo, SendGrid, Mailgun, Klaviyo, Kit, Amazon SES, Clay, Zapier, Make, Cloudflare, GoDaddy, Route 53, Google Postmaster Tools, Microsoft SNDS, and blacklist monitoring tools.
