Introduction # Get started with Bird Email, SMS, voice, and WhatsApp on one platform — per-channel endpoints over shared infrastructure. Create a key, send your first message, then wire up the rest at your own pace. Quickstart Get an API key View API Reference ## Choose a path Pick a use-case quickstart to go from zero to your first send. Every quickstart is one hand-held happy path — the canonical home that channel and product pages link to. ## Explore the docs Beyond the quickstarts, the documentation is organized into four areas. The **Guides** explain how Bird works and go channel-deep; the **Knowledge base** is the operational, how-do-I side; the **SDKs & CLI** are the official ways to call Bird from your own code; and the **API reference** documents every endpoint. ## The Email guide Email is the deepest section today. Start at the [Email overview](/docs/guides/email/overview) for the conceptual map, or jump straight to a topic: - **Sending** — [Sending email](/docs/guides/email/sending-email), [Bulk sending](/docs/guides/email/sending-bulk), [Categories](/docs/guides/email/categories), [Rate limits](/docs/guides/email/rate-limits) - **Domains & authentication** — [Sending domains](/docs/guides/email/sending-domains), [DKIM, SPF & DMARC](/docs/guides/email/dkim-spf-dmarc), [BIMI](/docs/guides/email/bimi) - **Reputation** — [Dedicated IPs & pools](/docs/guides/email/dedicated-ips-and-pools), [IP warmup](/docs/guides/email/ip-warmup), [Suppressions](/docs/guides/email/suppressions), [Deliverability](/docs/guides/email/deliverability) - **Visibility & testing** — [Tracking & metrics](/docs/guides/email/tracking-and-metrics), [Events](/docs/guides/email/events), [Mail sandbox](/docs/guides/email/testing-sandbox) - **Migrating** — from [SendGrid](/docs/guides/email/migrate/sendgrid), [Mailgun](/docs/guides/email/migrate/mailgun), [Amazon SES](/docs/guides/email/migrate/ses), or [Resend](/docs/guides/email/migrate/resend) ## The SMS guide SMS is in early access. Start at the [SMS overview](/docs/guides/sms/overview) for the map, or jump to [Sending SMS](/docs/guides/sms/sending-sms), the [SMS log](/docs/guides/sms/sms-log), [Tracking & metrics](/docs/guides/sms/tracking-and-metrics), or [Events](/docs/guides/sms/events). ## Next steps After your first send, wire up [Webhooks & events](/docs/guides/webhooks) to receive delivery events.
