What Twilio SendGrid is
Twilio SendGrid Email API is a cloud-based email delivery engine that sends messages without customers maintaining their own mail servers. Sending options include a RESTful Web API, SMTP relay, and SMTP API, with open-source libraries for C#, Go, Java, Node.js, PHP, Python, and Ruby. Dynamic templates, email validation, deliverability insights, and testing support message workflows. The Email Activity API, Event Webhook, and Activity dashboard track deliveries, opens, clicks, bounces, unsubscribes, and spam reports. Listed security controls include SPF, DKIM, DMARC, TLS encryption, and scoped or revocable API keys. Plans include a 60-day free trial, usage-based Pay as you go, Essentials from $19.95 per month, Pro from $89.95 per month with dedicated IPs, and custom-priced Premier. Each recipient email uses one credit, including deferred or spam-delivered messages. Twilio says SendGrid does not natively support HIPAA-compliant transmission.
