SendGrid

What SendGrid does

SendGrid covers two main use cases:

• Email API and SMTP service — for applications that need to send transactional email (receipts, notifications, password resets) at scale.
• Email campaigns — tools for marketers to create and send marketing email.

Because SendGrid is part of Twilio, you can combine it with the broader Twilio platform for things like identity verification, alerts, and support workflows.

Scale and deliverability

Twilio states the platform delivers more than 200 billion emails every month. The site also points to documentation and best-practice guides focused on deliverability, plus a partner network for integration help and deliverability optimization.

Getting started

• A free trial is available with no credit card required.
• Documentation covers API integration and sending.
• An AI assistant on the site can answer questions and help troubleshoot.
• A public status page shows product uptime.

Pricing

The homepage mentions "flexible pricing" but doesn't list plan tiers or rates. You'll need to check Twilio.com for current pricing details.

A note on the brand

SendGrid now lives on Twilio.com. The company's own messaging is that the same email products, documentation, and resources are "available and fully supported" there, so links and signups route through Twilio's site.
