SendGrid

Overview

SendGrid (by Twilio) is the most widely-used transactional email service. It handles email delivery at scale — from single welcome emails to millions of marketing messages. This skill covers sending emails via API and SMTP, dynamic templates, bulk/batch sending, event webhooks (opens, clicks, bounces), email validation, and deliverability configuration (SPF, DKIM, domain authentication).
