# Campaigns & Delivery

> Connect your email delivery provider, build reusable templates, and send one-off broadcasts or time-based sequences to precisely defined subscribers.

## Guides
- [Email Delivery Connections](https://mailrith.com/docs/email-delivery-connections.md): Mailrith is provider-agnostic — you connect your own email delivery service and Mailrith handles campaign logic, subscriber targeting, and engagement tracking on top of it.
- [Set Up Amazon SES](https://mailrith.com/docs/setup-amazon-ses.md): Use Amazon SES when you want AWS-native sending with full control over your sending identity, regional configuration, and bounce tracking through SNS notifications.
- [Set Up Postmark](https://mailrith.com/docs/setup-postmark.md): Postmark is a strong choice for reliable transactional-style delivery — connect it to Mailrith with a server token, optionally specify a message stream, and configure one webhook endpoint for event tracking.
- [Set Up SendGrid](https://mailrith.com/docs/setup-sendgrid.md): SendGrid connects to Mailrith with an API key — configure the Event Webhook to keep subscriber statuses in sync when bounces or spam complaints occur.
- [Set Up Mailgun](https://mailrith.com/docs/setup-mailgun.md): Mailgun requires a verified sending domain, a sending key, and a correctly matched API region — selecting the wrong region is the most common setup error, so confirm it before saving.
- [Set Up Resend](https://mailrith.com/docs/setup-resend.md): Resend is a lightweight option for API-driven email sending — connect it with an API key, verify your domain, and configure one webhook endpoint for automated subscriber status updates.
- [Set Up Brevo](https://mailrith.com/docs/setup-brevo.md): Brevo works well when you already manage your sender identities there — connect Mailrith with an API key and let Brevo handle delivery while Mailrith manages campaigns and subscriber targeting.
- [Set Up Custom SMTP](https://mailrith.com/docs/setup-custom-smtp.md): Use Custom SMTP when your email server is not on the provider list but supports standard SMTP authentication — enter the host, port, security mode, and credentials to connect.
- [Email Editor](https://mailrith.com/docs/email-editor.md): The email editor is shared across broadcasts, sequences, templates, automations, notifications, and confirmation emails. This guide explains how to build reliable email content and review it before it reaches subscribers.
- [Email Templates](https://mailrith.com/docs/email-templates.md): Email templates are your shared content library — build structural layouts once and reuse them as starting points for broadcasts and sequence emails across your workspace.
- [Broadcasts](https://mailrith.com/docs/broadcasts.md): Broadcasts are for newsletters, product launches, announcements, and any message that goes out once to selected subscribers — compose, target, test, and send or schedule from a single workflow.
