Deliverability Operations Skill

When to Use

• Inbox placement drops or spam-folder complaints.
• Preparing for IP/domain warmups or volume ramps.
• Auditing authentication, feedback loops, or compliance settings.

Framework

Signals to Monitor

1. Engagement – opens, clicks, unsubscribes, spam complaints by ISP.
2. Reputation – Google Postmaster, Microsoft SNDS, Talos/Barracuda, Spamhaus, Validity.
3. Infrastructure – SPF/DKIM/DMARC alignment, BIMI, TLS, reverse DNS, dedicated vs shared IP.
4. List Health – bounce types, spam traps, opt-in provenance, inactivity thresholds.

Playbook Steps

1. Snapshot key metrics over last 7/30 days.
2. Identify affected mailbox providers (Gmail, Outlook, Yahoo, etc.).
3. Validate authentication + sending domains.
4. Segment audiences by engagement tier; limit sends to VIP/high intent.
5. Recommend remediation actions (warmup plan, content refresh, list cleaning, cadence adjustment).

Templates

• Deliverability diagnostic worksheet (reputation + infrastructure + content).
• IP/domain warmup tracker (volume ramp table).
• Compliance checklist (CAN-SPAM, CASL, GDPR/CCPA, unsubscribe handling).

Tips

• Pair with segmentation skill to isolate healthy cohorts.
• Document every remediation change to correlate with future reputation shifts.
• Align marketing, security, and legal teams on consent language.
