Import the channel sender and one transport subpath for the smallest install surface.
The main `sently` package is for shared types and factories — not every provider.

<Callout title="The one rule">
  Prefer `sently/mailer` + `sently/transports/<provider>` (or the matching SMS / WhatsApp / push
  entrypoints) over pulling providers from the main barrel.
</Callout>

## Channel and core

| Import | Primary API |
| ------ | ----------- |
| `sently` | `createMailer`, `createSMTPMailer`, types, OAuth2, `SentlyError`, `consoleObserver`, `toChannelSendResult`, `FallbackTransport`, `WeightedFallbackTransport`, `CloudflareEmailTransport` |
| `sently/mailer` | `createMailer` only |
| `sently/smtp` | `createSMTPMailer` |
| `sently/sms` | `createSmsSender` |
| `sently/whatsapp` | `createWhatsAppSender` |
| `sently/push` | `createPushSender` |
| `sently/channel-result` | `toChannelSendResult`, `ChannelSendResult` |
| `sently/errors` | `SentlyError` hierarchy |
| `sently/idempotency` | `IdempotencyTransport` |
| `sently/dkim` | DKIM signing |
| `sently/react` | `reactPlugin` |
| `sently/plugins/template` | template plugin |
| `sently/auth/oauth2` | `OAuth2Client` |
| `sently/pool` | `SMTPPool` |
| `sently/observability` | `consoleObserver` |

## Transports

| Import | Use |
| ------ | --- |
| `sently/transports/<name>` | One provider or decorator (e.g. `sndr`, `inbucket`, `fcm`, `retry`) |

HTTP providers such as SNDR, Resend, and Plunk are **not** re-exported from `sently`.

## Webhooks

| Import | Use |
| ------ | --- |
| `sently/webhooks/<provider>` | One parser (+ verify helper when exported) |
| `sently/webhooks` | Convenience barrel of all named helpers |

Email: `brevo`, `mailgun`, `postmark`, `resend`, `sendgrid`, `ses`, `sndr`.
SMS / WhatsApp: `twilio-sms` (+ verify), `unifonic`, `whatsapp-cloud` (+ verify).

## Adapters

| Import | Use |
| ------ | --- |
| `sently/adapters/node` | Node TCP/TLS |
| `sently/adapters/bun` | Bun TCP/TLS |
| `sently/adapters/deno` | Deno TCP/TLS |
| `sently/adapters/cf` | Cloudflare `cloudflare:sockets` |

## Troubleshooting

<Accordions>

<Accordion title="Why is SndrTransport missing from import sently?">

Provider transports live on `sently/transports/*` so bare Node/Deno imports of `sently` do not load every HTTP client. Use `sently/transports/sndr`.

</Accordion>

</Accordions>
