Set Up the Netcore Mailer in FluentSMTP

With FluentSMTP, you can integrate Netcore (formerly Pepipost) into WordPress to improve email deliverability and authenticity. Netcore is one of the leading mailer options for WordPress, that is reliable and easy to set up.

This article will guide you through integrating Netcore into WordPress using the FluentSMTP plugin to send emails via SMTP.

Configuring Netcore

Go to Settings in the FluentSMTP top bar. If you haven't set up any connection yet, the setup wizard opens automatically. Otherwise, click the + Add Connection button.

Then select the Netcore icon from the provider grid.

NOTE

If you want to change the connection provider, click the change button next to the provider logo at the top of the page.

This opens the connection form, where you provide:

• From Email and From Name
• Force Sender Name: Uses this connection's From Name, whatever name the sending plugin set.
• API Key: Obtained from your Netcore account under Pepipost API Settings, described in the next section.

The rest of this guide walks through getting the API Key from Netcore, then pasting it into this form.

Get Netcore API Key

First, log into your Netcore account and click the Settings icon from the left sidebar, then select Integrations. Now, open the API tab. You will find your key listed under Name, or click the Create API Key button to generate a new one.

NOTE

Netcore's dashboard layout may look slightly different from the screenshot above depending on when you signed up. If a menu item has moved, look for Settings → Integrations → API in your account.

Then, go back to the Add Connection page under Settings in the FluentSMTP top bar, and paste the API Key you copied from Netcore inside the API Key box.

Once you input all the necessary information, click the Save Connection Settings button. Your Netcore server will be connected to your FluentSMTP.

Details of Netcore API Settings

• Store in Database: By default, this is enabled and strongly recommended. This will keep the information in the database in encrypted format. Tick Disable Encryption for API Key (Not Recommended) only if a security plugin rotates your SALT keys and the encrypted value keeps breaking.
• Store in wp-config.php: This allows you to store the access key inside the wp-config.php file by the following directive.

Copy the snippet below, replace the stars with your own credential, and paste it into your site's wp-config.php file.

define( 'FLUENTMAIL_PEPIPOST_API_KEY', '********************' );

That's all about setting up the Netcore Mailer in FluentSMTP to send emails from the WordPress website.
