### What Sending an Email Means

Mailrith prepares the campaign, your email delivery service sends it, and inbox providers decide where the message lands.

Before we get into buttons and settings, let us understand the basic flow. An email send has three parts. Mailrith plans the send, your email delivery service carries the message, and the subscriber's inbox decides where to place it.

Take a simple example. You have 2,000 subscribers and want to tell them about a new product update. In Mailrith, you write the email, choose who should receive it, choose the sender, and decide when it should go out. Your email delivery service, such as Amazon SES, Postmark, SendGrid, Mailgun, Resend, Brevo, or a custom SMTP service, does the actual delivery.

This split is important. If the message is badly written, the subscriber selection is wrong, or the sender is not trusted, the result can be poor even when the Mailrith setup is correct. Good sending is a mix of setup, subscriber choice, message quality, and regular review.

- Mailrith stores the email draft, subscriber rules, sending schedule, and campaign history.
- Your email delivery service authenticates the sender and sends the message through its own email infrastructure.
- Inbox providers such as Gmail, Outlook, Yahoo, and company mail servers decide whether the email reaches inbox, promotions, spam, or nowhere useful.
- Subscribers react by opening, clicking, unsubscribing, ignoring, bouncing, or marking the email as spam.

> If a send does not work, look at the whole chain. The problem may be the Mailrith campaign setup, the email delivery connection, the sender domain, the subscriber selection, the email content, or the subscriber's inbox.
