Set up a SendGrid account for email delivery. Covers API key creation (SG.-prefix), domain authentication (DKIM/SPF via CNAME records), Single Sender Verification for testing, SDK installation, and the relationship between SendGrid and Twilio credentials. Use before any other SendGrid skill. This skill is for SendGrid only — not the Twilio Email API (comms.twilio.com).

## Install

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

## From README

Overview SendGrid is Twilio's email delivery engine but uses a completely separate authentication system — SendGrid API keys (starting with SG.) are not Twilio API keys. You cannot use Account SID/Auth Token for SendGrid, and no Twilio MCP tools wrap SendGrid.
