# Configure toSend For Site Emails

> Send WordPress site emails through toSend on xCloud: add your sending key, assign it to a site, then check FluentSMTP and send a test email from the panel.

[**toSend**](https://tosend.com/) is a transactional email service for receipts, password resets and other site notifications. You can connect toSend to xCloud as an email provider in a few clicks. xCloud then sets it up in the FluentSMTP plugin on your WordPress site, and you can check FluentSMTP and send a test email from the xCloud panel, without opening WordPress admin.

This guide covers WordPress sites. For how site emails work on xCloud in general, see [Setting Up Site Emails For WordPress On xCloud](/docs/setting-up-site-emails-for-wordpress-on-xcloud/).

## Before You Start

You need two things from your toSend account:

-   **A verified sending domain.** Add the domain you will send from, such as `yourdomain.com`, in toSend. Then add the DNS records toSend shows you at your DNS provider: a DKIM `TXT` record, plus `MX` and SPF `TXT` records on a `send` subdomain. toSend verifies the domain on its own once it finds the records. Every From Email you use on a site must belong to a verified domain.
-   **A sending API key.** In toSend, open **API Keys** and create a key for your site. A sending key starts with `tsend_`. Admin keys (`tsend_admin_…`) cannot send email, and xCloud does not accept them. Copy the key when toSend shows it.

## Step 1: Add toSend As An Email Provider

From your xCloud dashboard, open **Settings → Integrations → Email Provider** and click the **'Add New Provider'** button.

Select **toSend**. Paste your sending key into **toSend Sending API Key**, give the provider a **Label**, and click **'Add Provider'**.

![Add toSend as an email provider](/_landing/docs/configure-tosend-for-site-emails-image-2.png)

You do not need to enter a host, port or username. xCloud connects to `smtp.tosend.com` on port 587 with TLS, which is what toSend requires. To replace the key later, edit the provider and paste a new sending key. Leave the field blank to keep the saved key.

## Step 2: Add toSend To Your Site

Open your site and go to **Email Config → Mail Delivery**. Select your toSend provider under **Existing Team Provider**. Enter a **From Name** and a **From Email** on your verified domain, then click **'Save Changes'**.

![Assign toSend to a WordPress site](/_landing/docs/configure-tosend-for-site-emails-image-3.png)

xCloud installs and activates the FluentSMTP plugin if needed, and saves the toSend connection in it. Your sending key is stored in the site's `wp-config.php` file, not in the WordPress database.

## Step 3: Check FluentSMTP From xCloud

Scroll down to the **FluentSMTP** section on the same page and click **'Check FluentSMTP'**.

xCloud reads FluentSMTP's own report from your site and shows:

-   **Each connection** with its From address and either **Settings OK** or **Needs attention**. If FluentSMTP finds a problem, its reason appears below the connection.
-   **Sent** and **Failed**: how many emails FluentSMTP has logged on this site.
-   **The FluentSMTP version** installed on the site.

For SMTP providers such as toSend, this check confirms that the saved settings are complete. It does not log in to toSend. Send a test email to confirm that toSend accepts them.

## Step 4: Send A Test Email

Under **Send Test Email**, enter the address that should receive it and click **'Send Test Email'**. FluentSMTP sends the email through toSend from your saved From Email, and xCloud shows the result.

A green message means toSend accepted the email. Check the inbox, and look in **Logs** in your toSend dashboard to follow its delivery. The Sent count refreshes after each test.

## Troubleshooting

### The test email fails with "Data not accepted"

![Test email refused by the provider](/_landing/docs/configure-tosend-for-site-emails-image-6.png)

toSend refused the message. This usually means the From Email does not use a domain verified in toSend. Verify the domain in toSend, or change the From Email to an address on a verified domain. Click **'Save Changes'**, then send the test email again.

### A connection shows Needs attention

![FluentSMTP connection that needs attention](/_landing/docs/configure-tosend-for-site-emails-image-7.png)

FluentSMTP is missing part of its settings, often because the site's `wp-config.php` was edited or replaced. Click **'Save Changes'** in the **Email Provider** section to write the toSend settings to FluentSMTP again, then click **'Check FluentSMTP'**.

### FluentSMTP is older than 2.3.0

![FluentSMTP is older than 2.3.0](/_landing/docs/configure-tosend-for-site-emails-image-8.png)

The checks and test emails use FluentSMTP's command-line tools, which arrived in FluentSMTP 2.3.0. Click **'Save Changes'** in the **Email Provider** section. xCloud updates FluentSMTP and keeps your settings. Then click **'Check FluentSMTP'** again.

### FluentSMTP is not active on this site

Click **'Save Changes'** in the **Email Provider** section. xCloud installs and activates FluentSMTP again.

## Frequently asked questions

### Which toSend key do I use in xCloud?

Use a sending API key, which starts with tsend_. toSend refuses admin API keys (tsend_admin_...) for sending email, and xCloud does not accept them.

### Why does the test email fail with "Data not accepted"?

toSend refused the message, most often because the From Email does not use a domain verified in toSend. Verify the domain in toSend, or change the From Email to an address on a verified domain, then click Save Changes and send the test email again.

### Do I still need to open WordPress admin to test mail?

No. The FluentSMTP section on the site's Mail Delivery page shows FluentSMTP's connection check and email counts, and sends a test email through FluentSMTP for you.

### What does Settings OK mean for toSend?

FluentSMTP found complete settings for the connection. For SMTP providers such as toSend, FluentSMTP does not log in during this check, so send a test email to confirm toSend accepts the key and the sender domain.
