What it is
Twilio SendGrid Email API is a cloud-based email delivery service for organizations that want to send email without maintaining their own email servers. Sending options include the RESTful Web API, SMTP relay and SMTP API, with open-source libraries for C#, Go, Java, Node.js, PHP, Python and Ruby. The product includes dynamic templates, email validation, deliverability insights and email testing. Its Email Activity API, Event Webhook and Activity dashboard can track deliveries, opens, clicks, bounces, unsubscribes and spam reports. Listed security features include SPF, DKIM, DMARC and TLS encryption; API keys can be restricted to selected actions or revoked without changing account credentials. Twilio states a 99% deliverability rate. Plans include a 60-day free trial at $0 per month, limited to 100 emails a day and 100 contacts; Pay as you go at no cost; Essentials from $19.95 a month; and Pro from $89.95 a month. Pro includes dedicated IPs. Each email sent to one recipient uses one credit, even if deferred or sent to spam. Twilio says the service does not natively support HIPAA-compliant data transmission.
