Monitor email program health with SendGrid Engagement Quality (SEQ) scores. Covers the SEQ API endpoints, the 5 scoring metrics (engagement recency, open rate, bounce classification, bounce rate, spam rate), eligibility requirements, and interpreting scores for deliverability improvement. Use when diagnosing SendGrid deliverability issues or monitoring sender reputation. Requires a SendGrid API key (SG.-prefix) — not applicable to the Twilio Email API (comms.twilio.com).

```sh
git clone https://github.com/twilio/ai /tmp/ai && ln -s /tmp/ai/skills/sendgrid/twilio-sendgrid-engagement-quality ~/.claude/skills/twilio-sendgrid-engagement-quality

## From README

Overview SendGrid Engagement Quality (SEQ) scores measure how "wanted" your email is by recipients. Higher scores (1-5 scale) correlate with better inbox placement. SEQ is a diagnostic tool — it tells you where your email program is healthy and where it needs improvement. Key insight: SEQ scores are correlated with deliverability. A higher score means more emails land in inboxes, not spam folders. --- Eligibility Requirements Your account must meet ALL conditions to receive scores: Pro or Premier Email API plan — SEQ is not available on Free or Essentials plans Open tracking enabled in SendGrid settings Minimum 1,000 messages sent in the previous 30 days If not eligible, the score and metrics fields are omitted from API responses entirely. --- The 5 Metrics All scores range from 1 (poor) to 5 (excellent). | Metric | What it measures | How to improve | |--------|-----------------|---------------| | engagementrecency | Are you sending to an engaged audience?
