## Direct Answer
Connect the email delivery service you trust. Mailrith manages subscribers, emails, and follow-up while that service sends each message.

- Use Amazon SES, Postmark, SendGrid, Mailgun, Resend, Brevo, or Custom SMTP.
- Test the connection before you use it for a real email.
- Keep sender setup, limits, costs, bounces, and complaints visible.

## What This Feature Helps You Do
- **Choose Your Email Delivery Service:** Keep the email delivery service you already trust instead of moving everything into one combined email platform.
- **Clear Cost Split:** Your Mailrith plan covers email marketing. Your email delivery service handles sending costs, sending limits, and its own rules.
- **Understand Delivery Problems:** When an email does not arrive, check the service account, sending limits, bounces, and complaints instead of guessing what happened.

## When To Use This Feature
- You already use Amazon SES, Postmark, SendGrid, Mailgun, Resend, Brevo, or a service that works with Custom SMTP.
- You want Mailrith to manage subscribers, emails, follow-up, and reports while another service sends.
- You care about sender-domain setup, sending limits, bounces, and complaints.

## When This May Not Be The First Thing To Set Up
- You want one company to manage email marketing, sending, billing, and delivery support for you.
- You do not want to manage connection details, sender domains, or bounce and complaint setup.
- Your sender domain is not ready for marketing email yet.

## A Simple Setup Path
1. Choose the service that should send emails for this workspace.
2. Verify the sender or domain inside that service before you connect Mailrith.
3. Create the connection details Mailrith needs by following the guide for that service.
4. Add the connection in Mailrith, then send a test email.
5. Set up bounce and complaint updates where the service supports them. Then start with a small engaged segment.

## Common Mistakes To Avoid
- **Connecting Before The Domain Is Ready:** Connection details are not enough. The sending domain, account approval, and domain status matter too.
- **Ignoring Sending Limits:** Daily limits, sending-speed limits, account reviews, and service rules still apply when Mailrith sends through that service.
- **Skipping Bounce And Complaint Updates:** Bounces and complaints are important signals. Connect those updates when they are available.

## How This Connects With The Rest Of Mailrith
- Broadcasts and sequences choose a delivery connection before sending.
- Automations can send emails through the same sending setup.
- Workspaces keep sending details separate by brand or client.
- Free tools can help check domain records and email delivery before a launch.
