## Description

Changrid Email Delivery connects WordPress `wp_mail()` calls to a Changrid workspace
through the dedicated, API-key-protected WordPress endpoint.

The plugin is free, and you can start sending with Changrid’s Free plan. Upgrade
only when you need more sending capacity, routing, retention, workspace capacity,
or provider options.

Features:

 * Uses workspace access and secret keys; no WordPress user password is shared.
 * Start sending with the Changrid Free plan; no separate plugin license is required.
 * Routes normal WordPress mail, including HTML and plain-text messages.
 * Supports To, Cc, Bcc, and Reply-To addresses.
 * Keeps the From identity protected by Changrid provider configuration while allowing
   an optional site-wide Reply-To address.
 * Optional open, click, and unsubscribe tracking.
 * Optional fallback to native `wp_mail()` after a Changrid request error.
 * Sends one explicit test message from the settings screen.
 * Checks credentials and send permission without sending an email.
 * Keeps automatic workspace routing as the recommended default, with an advanced
   fixed-provider option for strict route control.
 * Keeps a small local diagnostic log without recipient addresses, subjects, or 
   message bodies.
 * Supports constants in `wp-config.php` so production secrets do not need to be
   stored in the WordPress database.

Changrid returns an accepted/queued response. Acceptance is not proof of final delivery.
Final status and provider events remain available in the Changrid workspace where
supported by the configured provider.

This plugin currently does not send attachments through Changrid. When fallback 
is enabled, messages with attachments continue through native `wp_mail()`.

### External service

This plugin sends email data to the Changrid service when the site owner enables
Changrid delivery. The request may contain recipient email addresses and names, 
the email subject and body, Reply-To addresses, tracking preferences, and a generic
plugin-version User-Agent. The User-Agent does not include the WordPress site URL.
Changrid uses this data to enqueue and operate the requested communication through
the workspace’s configured provider route.

Service links:

 * Changrid: https://changrid.com/
 * Documentation: https://changrid.com/docs
 * Terms: https://changrid.com/legal/terms
 * Privacy policy: https://changrid.com/legal/privacy
 * Acceptable use: https://changrid.com/legal/acceptable-use

The service is not contacted until the plugin is configured and a message is sent,
or the administrator deliberately presses the connection-check or test button.

The connection-check button contacts Changrid only after the administrator has
 
configured credentials and deliberately starts the check. It verifies the key and
the `communications:send` scope and loads active email provider choices without 
creating an email.

### Plans and billing

The WordPress plugin itself is free and GPL-licensed. A Changrid account is
 required
to use the hosted delivery service. Changrid has a Free plan and paid plans with
different managed-message allowances, routing features, retention, workspace capacity,
and provider options. Current prices and limits are shown at https://changrid.com/
pricing and are supplied by Changrid’s live plan catalog.

Your WordPress hosting, domain, and any bring-your-own provider charges are
 separate
from the Changrid subscription. BYOP traffic and managed-delivery allowances may
be treated differently by the selected Changrid plan; review the live plan details
before upgrading.

### Privacy

The local activity log stores UTC time, result, recipient count, execution ID, HTTP
status, and an error code. It does not store recipient addresses, subject lines,
or message content. Uninstalling the plugin deletes its settings and local log.

Enabling open or click tracking may have privacy and consent implications in your
jurisdiction. Those options are off by default. Site owners are responsible for 
their notices, consent choices, retention settings, and lawful use.

## Installation

 1.  Upload the plugin ZIP in Plugins > Add New > Upload Plugin, or copy the `changrid-
     email-delivery` directory into `/wp-content/plugins/`.
 2.  Activate the plugin.
 3.  Open Settings > Changrid Email.
 4.  Create a workspace access key with `communications:send` permission in Changrid.
 5.  Enter the access key and secret key, then save the settings.
 6.  Optionally set a default Reply-To address for replies to website email.
 7.  Press Check connection. This does not send an email.
 8.  Keep Automatic workspace routing (recommended), or choose a fixed active provider
     under Advanced delivery routing and save again.
 9.  Send one test to an address you control.
 10. Verify the accepted execution and final delivery state in Changrid before enabling
     production routing.

To disconnect the site, disable Changrid delivery, clear the access key, select 
the remove-stored-secret option, save, and revoke the integration key in Changrid.

For production, credentials can be stored in `wp-config.php`:

    ```
    define( 'CHANGRID_ACCESS_KEY', 'your-access-key' );

    define( 'CHANGRID_SECRET_KEY', 'your-secret-key' );
    ```

The optional `CHANGRID_API_BASE_URL` constant overrides the API base URL.

## FAQ

### Does this replace SMTP?

It short-circuits `wp_mail()` and submits the message to Changrid over HTTPS. The
actual provider path is selected and operated in the Changrid workspace.

### Do I need to configure an API base URL?

No. The plugin automatically uses Changrid’s secure production API. The `CHANGRID_API_BASE_URL`
constant is only for advanced or self-hosted installations and is not required for
normal setup.

### Does accepted mean delivered?

No. HTTP 202 means Changrid persisted or accepted the request. Delivery depends 
on routing, provider state, sender identity, suppression checks, and the recipient
system.

### What happens when Changrid is unavailable?

If native-mail fallback is enabled, the plugin lets WordPress continue with its 
normal `wp_mail()` transport after a request error. It does not retry a response
that Changrid reported as accepted.

A network timeout is ambiguous: Changrid may have accepted the request even though
WordPress did not receive the response. Native fallback in that situation can deliver
a duplicate. Disable fallback for duplicate-sensitive messages and review the Changrid
execution before manually retrying an uncertain send.

### Are attachments supported?

Not in this release. Messages with attachments use native `wp_mail()` when fallback
is enabled, or fail if strict Changrid-only behavior is selected.

### Are Cc and Bcc headers preserved?

All To, Cc, and Bcc destinations are submitted as individual Changrid recipients.
They do not receive a visible shared recipient header, which keeps Bcc destinations
private.

### Can I change the From address in WordPress?

No. The From email and name come from the active provider route in Changrid. This
prevents WordPress from requesting an unverified identity that would fail provider,
SPF, DKIM, or DMARC checks. Use the plugin links to manage providers or verify a
sending domain in Changrid. WordPress can set a per-message Reply-To header, and
the plugin also supports an optional site-wide default Reply-To address.

### Can I choose a specific email provider?

Yes. Automatic workspace routing is the recommended default because Changrid can
apply route priority, health, capacity, and failover rules. After pressing Check
connection, open Advanced delivery routing to choose an active provider. A fixed
provider controls the sender route but disables automatic failover for those WordPress
requests.
