## Popis

[💬 Ask a Question](https://github.com/webguyio/support/issues) | [📧 Email Me](https://cs.wordpress.org/plugins/sammy-smtp/webguywork@gmail.com?output_format=md)

Dead simple SMTP (Simple Mail Transfer Protocol) integration under _Settings  SMTP_.
No upsell theater to make it seem like it’s super complicated and you have to pay
for some premium upgrade or your emails will never make it into inboxes.

 * Manual SMTP with any host, port, and encryption combination.
 * One click connect for Google and Microsoft, using OAuth so no password is ever
   stored for those accounts.
 * SMTP passwords and OAuth secrets are encrypted at rest, derived from your site’s
   own unique keys, never stored in plain text.
 * Built-in test email form with a link to mail-tester.com for a full deliverability
   check.
 * No dependencies, no external libraries, no telemetry.

Works with Proton, Google, Microsoft, Amazon, Mailgun, and most other SMTP services.

## Nejčastější dotazy

### Why aren’t emails being delivered?

First, test the deliverability of your email at [mail-tester.com](https://www.mail-tester.com/).
Then adjust as needed. You’ll likely need to adjust your DNS settings at your domain
registrar (like GoDaddy) or your CDN (like Cloudflare).

### I moved my site to a new server and my SMTP password or connections stopped working?

Stored credentials are encrypted using keys derived from your site’s `AUTH_KEY` 
and `AUTH_SALT` values in `wp-config.php`. If those values change during a migration,
saved credentials can no longer be decrypted and you’ll need to re-enter your SMTP
password or reconnect Google/Microsoft. This is expected, and safer than credentials
that could be copied in plain text between servers.

### Are there any external dependencies or privacy concerns?

The plugin itself doesn’t track or collect your data in any way. However, unless
you run your own email server, integrating SMTP inherently involves connecting to
a third-party server, which will have its own privacy policy. Connecting, whether
via manual SMTP or OAuth, exposes your website’s domain, server IP, and other email
related credentials to that provider. Once SMTP is set up, all future WordPress 
email, both transactional and contact form submissions, will be routed through your
SMTP service of choice, where different levels of logging will take place. See the
privacy policies for [Google](https://policies.google.com/privacy) and [Microsoft](https://privacy.microsoft.com/privacystatement).
