## Direct Answer
Mailrith does not hide sending inside a shared setup. You connect the email sending service you trust, and Mailrith handles the list, emails, and follow-up around it.

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

## What This Feature Helps You Do
- **Choose Your Sending Service:** You can keep the email sending service you already trust instead of moving everything into one bundled email platform.
- **Clear Cost Split:** Mailrith is the marketing software. Your sending service handles sending costs, limits, and its own rules.
- **Better Debugging:** When delivery has a problem, you can check the sending setup instead of guessing what is hidden behind the app.

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

## When This May Not Be The First Thing To Set Up
- You want one vendor to manage every delivery and software decision for you.
- You do not want to touch API keys, SMTP 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 the emails for this workspace.
2. Verify the sender or domain inside that service before connecting Mailrith.
3. Create the API key or SMTP credentials Mailrith needs.
4. Add the connection in Mailrith and 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. Sender authentication, account approval, and domain status matter too.
- **Ignoring Sending Limits:** Daily limits, sending rates, account reviews, and service rules still apply when Mailrith sends through that service.
- **Skipping Feedback Events:** 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 separated by brand or client.
- Free tools can help check DNS and deliverability before a launch.
