# FAQ

## General

**What does BooleanSMTP do?**
It takes over WordPress's `wp_mail()` function and sends every email your site generates — contact forms,
password resets, order receipts — through a mail provider you choose, instead of your web server.

**Which providers does it support?**
Five mailers: Amazon SES, Google Workspace, Microsoft Outlook, Custom SMTP (any SMTP server)
and PHP Mail. See [Mailers](/docs/mailers/).

**Is my email data secure?**
Every credential you enter is encrypted before it's stored.

## Setup

**Can I use more than one provider?**
Yes. See [One connection per sender](/docs/advanced/one-connection-per-sender/) for how BooleanSMTP chooses a connection and
[Fallback and retries](/docs/advanced/fallback-and-retries/) for what happens when a send fails.

## Sending

**Does BooleanSMTP queue my emails?**
No. Only a message that already failed is queued, and only when **Retry on other connections** is on. See
[Fallback and retries](/docs/advanced/fallback-and-retries/) for how it works.

**What happens when an email fails to send?**
BooleanSMTP logs the provider's error and applies your fallback and retry settings. See
[Fallback and retries](/docs/advanced/fallback-and-retries/) or [troubleshooting](/docs/troubleshooting/) if it keeps failing.

## Logs

**How long are email logs kept?**
You control this with **Retention Period** in **Settings → Logging & Retention**. See
[Log retention](/docs/logs/retention/) for the available periods and default.

**Can I export my logs?**
Yes, from the command line: `wp boolean-smtp logs:export` prints recent logs as JSON. Redirect its output
to a file if you want to save it, for example `wp boolean-smtp logs:export > logs.json`. There's no
export button on the **Email Logs** page itself. See the WP-CLI reference
for its options.

## Developers

**Is there a REST API?**
Yes, and every route needs WordPress admin access — see
the REST API reference for the full list of endpoints.
