twilio-email-send
✓★ 4,081by openai
Use when the caller has Twilio credentials (Account SID + Auth Token or API Key SID + Secret) and needs to send email via comms.twilio.com/v1/Emails. This is Twilio-native email — NOT SendGrid. Do NOT use if the caller has a SendGrid API key (SG.-prefix) — use twilio-sendgrid-email-send instead. Covers single sends, batch sends up to 10,000 recipients, Liquid personalization, operation tracking, and error handling.

Send and verify one-time passcodes (OTPs) via Twilio Verify over SMS, RCS, voice, email, or WhatsApp. Covers creating a Verify Service, sending tokens, checking submitted codes, automatic WhatsApp-to-SMS fallback, and service configuration. TOTP is supported via the Factors API (a separate family from channel-based OTP). Use this skill to add phone or email verification or two-factor authentication to any application.
