What this skill does

1. 1Sizes email infrastructure from scratch: calculates how many domains and mailboxes you need based on monthly send volume targets.
2. 2Configures all four required DNS records (MX, SPF, DKIM, DMARC) for each sending domain across Google Workspace and Microsoft 365.
3. 3Runs a 3-week warmup protocol before first campaigns go live, with health score benchmarks and a ramp schedule by provider.
4. 4Monitors deliverability health metrics post-launch: open rate 50%+, bounce rate under 2%, spam rate under 0.1%.
5. 5Diagnoses and recovers from infrastructure failures: DNS misconfigurations, warmup red flags in Instantly, and email blacklist incidents.

When to use

• You're setting up cold email infrastructure from zero and need to know how many domains and mailboxes to buy.
• You see a red flame or health warning in Instantly and need to diagnose whether it's DNS, warmup, or volume.
• Your bounce rate is climbing above 3% and you need to trace it back to infrastructure or sending behavior.
• You're scaling from 1,000 to 10,000 emails per month and need to add domains and mailboxes without hurting deliverability.
