Send an email

Send an email

Sends an email from a verified sender, with up to 1,000 personalizations that each set their own recipients.

Set up

Use the first option your agent supports.

CLI (official)

Install the command, then confirm it runs.

brew tap twilio/brew && brew install twilio
twilio --version

Run twilio email:send.

Set $SENDGRID_API_KEY in your environment first (get a key: https://app.sendgrid.com/settings/api_keys).

API (official)

• Base URL: https://api.sendgrid.com
• Endpoint: POST /v3/mail/send
• Auth: send the header Authorization: Bearer $SENDGRID_API_KEY
• Get a key: https://app.sendgrid.com/settings/api_keys
• Docs: https://www.twilio.com/docs/sendgrid/api-reference

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
