My Step-by-Step Fix Workflow
A transparent and secure process to get your issues resolved quickly.
Header & Reputation Check
I request a sample email sent from your system, then inspect its full raw headers and verify your sending IP's reputation status.
Blacklist Delisting Support
If your IP is blocklisted, I identify the root spam cause, suggest changes, and draft delisting requests to major database providers.
SMTP & DNS Configuration
I align DNS authentication records and configure proper SMTP relays or custom return-path tracking domains.
Warmup & Delivery Test
We run test campaigns to a clean seed list to verify placement in inbox tabs of Gmail, Yahoo, Outlook, and corporate networks.
Frequently Asked Questions
Have questions about my technical services? Find quick answers below.
Sudden spam placement is usually triggered by: 1) A change in Gmail/Yahoo deliverability rules (such as the DMARC requirement implemented in 2024), 2) IP sharing on shared hosting where other users send spam, or 3) High bounce rates triggering a domain reputation drop.
No legitimate consultant can guarantee 100% placement because receiving servers use proprietary algorithms. However, I guarantee that your technical infrastructure (SPF, DKIM, DMARC, DNS, IP reputation) will meet all best practices, which maximizes your deliverability score.
Email Service Providers (ESPs) like Klaviyo or SendGrid default to tracking clicks and opens using their own shared domains. If another client spams with that tracking domain, your deliverability suffers. Setting up a custom tracking domain on your own subdomain isolates your reputation.
