What Twilio SendGrid is
Twilio SendGrid Email API is a cloud-based email delivery service for sending messages without maintaining customer-owned email servers. Sending options include a RESTful Web API, SMTP relay, and SMTP API, with open-source client libraries for C#, Go, Java, Node.js, PHP, Python, and Ruby. Tools include dynamic templates, email validation, deliverability insights, and email testing. The Email Activity API, Event Webhook, and Activity dashboard track deliveries, opens, clicks, bounces, unsubscribes, and spam reports. Listed security features include SPF, DKIM, DMARC, TLS encryption, and API keys that can be limited to selected actions or revoked. Twilio states a 99% deliverability rate. A 60-day free trial costs $0/mo and is limited to 100 emails per day and 100 contacts; each email sent to one recipient uses one credit, including deferred or spammed messages. Pay as you go has no monthly base fee, while Premier pricing is custom. Twilio states that SendGrid does not natively support HIPAA-compliant data transmission.
