About Sendgrid

SendGrid's v3 API reference documents the endpoints available for the Twilio SendGrid email platform. It covers mail sending (including scheduled sends, batching, and cancellation), account provisioning, and deliverability features such as domain authentication, link branding, reverse DNS, sender verification, and IP warmup and pooling.

The reference also documents email validation (single and bulk), email activity and log filtering, event tracking and webhook configuration, and statistics retrieval by browser, client type, device, country, and mailbox provider. Additional sections cover legacy marketing campaign tools (campaigns, categories, custom fields, lists, recipients, segments, sender identities) alongside a newer contacts API for managing and importing/exporting contact records.

This documentation is intended for developers integrating email sending, deliverability management, or contact/marketing campaign functionality into applications via SendGrid's API.
