# Let Codex send the email.

A Codex task that finishes at 3am can say so. Release notes, build failures, a report someone asked for: written and sent in the same task, 2¢ an email. No SMTP server, no sending provider account.

## Connect your agent

Read the [Codex setup guide](https://taskfuel.ai/docs/setup-cli/).

Use one TaskFuel account and prepaid balance. Inspect the provider and request quote before a paid call, then review the returned response and recorded charge.

## When to use it

### Ship it and announce it.

Codex already knows what changed, because it wrote it. Let it draft the note and send it in the same task instead of leaving you a paragraph to copy into a mail client.

### Report the failure to a person.

A task that fails at 3am reports into a log nobody reads until morning. 2¢ puts it in an inbox instead.

### Skip the SMTP setup.

Wiring a sending provider into a project means an account, a verified domain and a secret in the environment. This needs none of them.

## Questions

### Can Codex send emails?

Not on its own: it has no mail server behind it. Connect TaskFuel and it composes and sends the message as a tool call, 2¢ an email.

### Do I need an SMTP server or a verified domain?

No. One TaskFuel account and one prepaid balance covers it. TaskFuel pays the provider and bills your balance, so nothing lands in the project's environment.

### What does an email cost?

2¢ to send. An inbox of its own is $1 for 30 days, sending from that inbox is 0.5¢, and reading a message is 0.1¢.

### Can a task read the reply?

Yes, if you buy it an inbox. It can list and read messages at 0.1¢ each and delete them for free.

### What if a send fails?

Upstream 4xx and 5xx responses are not charged. A successful provider response can still be charged when its answer is empty or unhelpful.
