Deliverability Watchdog
Know your domain health before your emails hit spam
Post-2024, email deliverability is a technical minefield. This skill monitors your sending domains, checks authentication records, tracks reputation scores, and alerts you before problems tank your outreach.
INGREDIENTS
PROMPT
Create a skill called "Deliverability Watchdog". Monitor these sending domains and mailboxes: [list domains]. Daily, check: DMARC/SPF/DKIM configuration and alignment, domain reputation scores, blacklist status across major blocklists, bounce rates by domain and mailbox, and warm-up progress for new domains. Alert me immediately if: any domain lands on a blacklist, bounce rate exceeds 5%, or authentication records change unexpectedly. Weekly summary: overall health score per domain, volume sent, bounce rate trends, and recommended actions. Include remediation steps for any issues found.
How It Works
The skill continuously monitors the health of your email sending infrastructure.
DMARC, SPF, DKIM alignment, blacklist checks, and bounce-rate trends are reviewed on a schedule so you can spot issues before they become painful.
