What it is

Twilio SendGrid Email API sends email through a cloud-based delivery service, so customers do not need to maintain their own email servers. Messages can be sent through its RESTful Web API, SMTP relay, or SMTP API, with open-source client libraries for C#, Go, Java, Node.js, PHP, Python, and Ruby. Tools include dynamic templates, an Email Validation API, deliverability insights, and email testing. The Email Activity API, Event Webhook, and Activity dashboard track deliveries, opens, clicks, bounces, unsubscribes, and spam reports. Security features listed include SPF, DKIM, DMARC, TLS encryption, and API keys that can be limited or revoked. Twilio states a 99% deliverability rate. A 60-day free trial is listed at free, with limits of 100 emails per day and 100 contacts. Pay as you go is free; Essentials starts at $19.95 a month and Pro at $89.95 a month. Each email to one recipient uses a credit, even if deferred or sent to spam. Twilio says SendGrid does not natively support HIPAA-compliant data transmission.
