Diagnostic and advisory skill for email deliverability problems. Use when a developer asks why emails are going to spam, not reaching the inbox, getting blocked, bouncing, or how to improve sender reputation — with or without a specified platform. Covers SendGrid-specific tooling: SPF, DKIM, DMARC, BIMI, IP warmup, list hygiene, bounce/spam rate thresholds, and Engagement Quality Score (SEQ).

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'twilio-sendgrid-deliverability-advisor' ] || [ -L ~/.agents/skills/'twilio-sendgrid-deliverability-advisor' ]; then echo 'A skill folder named twilio-sendgrid-deliverability-advisor already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/openai/plugins' "$d" && git -C "$d" checkout --quiet 'd420d13051bffe4543ed39e30fa46b87148e47dd' -- 'plugins/twilio-developer-kit/skills/twilio-sendgrid-deliverability-advisor' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/twilio-developer-kit/skills/twilio-sendgrid-deliverability-advisor' ~/.agents/skills/'twilio-sendgrid-deliverability-advisor' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'twilio-sendgrid-deliverability-advisor' ~/.claude/skills/'twilio-sendgrid-deliverability-advisor' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
