FAQ
Why are my Substack emails going to spam?
Emails usually go to spam due to missing SPF, DKIM, or DMARC records, poor sender reputation, DNS misconfiguration, or high bounce/spam complaint rates. I perform a full technical audit to identify the root cause and implement a permanent deliverability fix.
Do I need a custom domain for better deliverability?
Yes. A properly configured custom domain with correct DNS, SPF, DKIM, and DMARC authentication significantly improves inbox placement and brand trust. I handle the complete Substack domain setup for you.
Will this permanently fix my deliverability issues?
Yes — if the issue is technical. I implement industry-standard email authentication, domain configuration, and sender reputation optimization to ensure long-term inbox placement stability.
