## Description
**Nanomailer for AWS SES** is a streamlined WordPress plugin that routes all emails
sent using `wp_mail()` through [Amazon Simple Email Service (SES)](https://aws.amazon.com/ses/)—
a highly reliable, scalable cloud-based email platform.
It supports Contact Form 7, Gravity Forms, WPForms, and any other plugin that uses
the standard WordPress mailing function. Nanomailer handles the full process of
authenticating with AWS, preparing email headers, and securely delivering messages
through the SES API.
There is no bloat or unnecessary overhead. It’s built with a focus on speed, clean
integration, and minimal configuration. When removed, it leaves behind no database
clutter.
### External Services
This plugin connects to **Amazon Simple Email Service (SES)** in order to send emails.
* **Service used:** Amazon Simple Email Service (https://aws.amazon.com/ses/)
* **What is sent:** When a WordPress email is triggered using `wp_mail()`, the
plugin sends the email message (recipient, subject, body, headers) to the SES
API endpoint for delivery.
* **When:** Only when an email is sent using `wp_mail()`.
* **Where:** To the regional SES API endpoint (e.g. `https://email.eu-west-1.amazonaws.
com`), depending on your configuration.
* **Is an account required?** Yes, you must have an active AWS account with SES
access and a verified email/domain.
* **Terms & Privacy:**
- [AWS Terms of Use](https://aws.amazon.com/service-terms/)
- [AWS Privacy Policy](https://aws.amazon.com/privacy/)

## FAQ
### Does Nanomailer work with other mailing functions?
No. Nanomailer only overrides the built-in wp_mail() function. Emails sent via other
libraries (like PHPMailer directly) are not handled.
### Does it store or log email content?
No. Nanomailer does not store, log, or retain any email content or headers after
sending.
### Are any emails sent without my knowledge?
Never. Emails are only sent when your WordPress site triggers wp_mail().
