Insights on cold email, deliverability, and scaling your outreach infrastructure.
Dedicated IP vs shared IP for cold email: most senders should stay on managed shared pools. A dedicated IP only pays off above ~100,000 steady emails a year.
Read DMARC aggregate reports: decode the XML, spot the alignment trap where SPF passes but DMARC fails, and find unauthorized senders sending as your domain.
A sending subdomain builds its own Gmail reputation separate from your root, so a cold-email burn never touches the brand domain your business actually runs on.
Custom tracking domain setup points a branded CNAME at your ESP's redirect host so opens and clicks resolve under your own domain, not a shared, listed one.
MTA-STS and TLS-RPT configuration for cold senders: publish the policy file, add two DNS records, run testing mode, then enforce TLS 1.2+ on inbound mail.
BIMI setup for cold email senders: the SVG Tiny PS logo, the VMC or CMC certificate (around $1,499/yr), the DNS record, and whether inbox logos are worth it.
A DMARC p=reject migration playbook: climb the none, quarantine, reject ladder safely. Google requires bulk senders to publish at least p=none. Here's the ramp.
A step-by-step plan to recover a burned cold email domain: stop the bleeding, diagnose, re-warm, and decide whether to rebuild or replace, with Gmail's real reputation thresholds.
Switching cold email platforms doesn't reset your domain reputation. Here's how to migrate mailboxes, sequences, and warmup without dropping live campaigns.
