## Opis

**Mailster SparkPost Integration** connects [SparkPost](https://www.sparkpost.com/)
to the [Mailster Newsletter Plugin for WordPress](https://mailster.co/?utm_campaign=wporg&utm_source=wordpress.org&utm_medium=readme&utm_term=SparkPost)
so you can send campaigns and transactional mail through SparkPost instead of your
web host’s mail server.

Use it when you want scalable newsletter delivery on SparkPost while keeping Mailster’s
campaign editor, lists, and automation.

> This plugin requires [Mailster](https://mailster.co/?utm_campaign=wporg&utm_source=wordpress.org&utm_medium=readme&utm_term=SparkPost)**
> 4.0** or newer and a [SparkPost](https://www.sparkpost.com/) account with a Master
> API key and a verified sending domain. When SparkPost is the active delivery method,
> outgoing email content and delivery metadata are sent to SparkPost (US or EU API,
> depending on your endpoint setting).

#### Why send Mailster newsletters with SparkPost?

 * **SparkPost delivery for Mailster** — Registers SparkPost as a delivery method
   under **Newsletter  Settings  Delivery**.
 * **WEB API or SMTP API** — Send via the SparkPost Transmissions (WEB) API (recommended),
   or use SparkPost SMTP with TLS on port **587** or **2525**.
 * **US or EU endpoint** — Choose the default SparkPost API/SMTP hosts or the **
   EU** endpoint (`api.eu.sparkpost.com` / `smtp.eu.sparkpostmail.com`).
 * **API key verification** — Verifies your Master API key against the SparkPost
   account and can sync Mailster’s send limit from SparkPost usage.
 * **Sending domains and subaccounts** — Lists verified sending domains and optional
   SparkPost subaccounts from your account.
 * **Open and click tracking in SparkPost** — Optionally enable SparkPost open/click
   tracking (account defaults, none, opens, clicks, or both).
 * **IP pool and tags** — Set a dedicated IP pool ID and comma-separated tags attached
   to each transmission.
 * **Bounce and complaint sync** — Reads SparkPost message events and applies bounces,
   complaints, and unsubscribes in Mailster (SparkPost handles soft delays).

#### How it works

 1. Install and activate **Mailster SparkPost Integration** alongside Mailster 4.0+.
 2. Create a SparkPost account, verify your sending domain (DNS), and create a **Master**
    API key with permissions for Account, Message Events, Sending Domains, Subaccounts,
    Transmissions, and (if using SMTP) Send via SMTP.
 3. Open **Newsletter  Settings  Delivery**, select the **SparkPost** tab, enter your
    API key, choose the endpoint if needed, and save.
 4. Select WEB API or SMTP, configure tracking, IP pool, and tags if desired, then 
    send a test email from a verified From domain.
 5. Run your Mailster campaigns through SparkPost.

## Instalacja

 1. Upload the entire `mailster-sparkpost` folder to the `/wp-content/plugins/` directory,
    or install from the WordPress plugins screen.
 2. Activate the plugin through the **Plugins** menu in WordPress.
 3. Make sure [Mailster](https://mailster.co/?utm_campaign=wporg&utm_source=wordpress.org&utm_medium=readme&utm_term=SparkPost)**
    4.0** or newer is installed and active.
 4. In SparkPost, verify your sending domain and create a Master API key with the permissions
    described in the [setup guide](https://kb.mailster.co/send-your-newsletters-via-sparkpost/?utm_campaign=wporg&utm_source=SparkPost&utm_medium=readme).
 5. Go to **Settings  Newsletter  Delivery**, open the **SparkPost** tab, enter your
    API key, choose Default or EU endpoint, and save.
 6. Choose WEB API (recommended) or SMTP API, configure optional tracking / IP pool/
    tags, and send a test email using a verified From address.

## Najczęściej zadawane pytania

### Does this plugin work without Mailster?

No. This is a delivery addon for the [Mailster Newsletter Plugin](https://mailster.co/?utm_campaign=wporg&utm_source=wordpress.org&utm_medium=readme&utm_term=SparkPost)
and requires Mailster **4.0** or newer.

### Do I need a SparkPost account?

Yes. You need a SparkPost account, a verified sending domain (or verified From address),
and a Master API key. SparkPost is a paid email delivery service; see SparkPost 
for current plans.

### What is the difference between WEB API and SMTP?

**WEB API** (recommended) sends through SparkPost’s Transmissions API and usually
returns clearer errors. **SMTP API** relays via `smtp.sparkpostmail.com` (or the
EU host) on port 587 or 2525 with TLS. Both are available in the SparkPost delivery
settings.

### Why Master API key?

Mailster needs Account read access (and related permissions) to verify the key, 
list sending domains and subaccounts, read message events for bounces, and send 
transmissions. A restricted key without those permissions will not work fully.

### Can I use SparkPost EU?

Yes. Choose the **EU** endpoint in the SparkPost delivery settings to use the EU
API and SMTP hosts.

### How are bounces handled?

When SparkPost is the active delivery method, bounce handling is driven by SparkPost
message events synced into Mailster. Mailster’s own bounce mailbox settings are 
ignored for this delivery method.

### Is email data sent to a third party?

Yes. When this delivery method is active, Mailster sends email content and related
delivery metadata to **SparkPost** so messages can be delivered. Bounce and engagement
events are read back from SparkPost’s APIs.

### Where can I get support?

For Mailster and this addon, see [mailster.co](https://mailster.co/?utm_campaign=wporg&utm_source=wordpress.org&utm_medium=readme&utm_term=SparkPost)
and the [SparkPost setup guide](https://kb.mailster.co/send-your-newsletters-via-sparkpost/?utm_campaign=wporg&utm_source=SparkPost&utm_medium=readme).
For SparkPost account, billing, and API questions, use [SparkPost documentation](https://developers.sparkpost.com/).
