Mailmojo

Mailmojo is a Norwegian email and SMS marketing platform built for businesses 
that want professional results without the complexity. This official plugin bridges 
your WordPress site and your Mailmojo account in three practical ways.
Grow your list with subscribe popups 
Once the plugin is installed and connected with your Mailmojo account, your 
published subscribe popups appear on your site automatically, no extra setup 
needed. The plugin loads a small script in the background so your popups just 
work, respecting the display rules you’ve already configured in Mailmojo. Popups 
set to show site-wide will appear everywhere; those targeting specific URLs will 
appear only on the right pages.
Add subscribe buttons anywhere 
Use the Mailmojo Popup Button block to place a subscribe button in any post or 
page. Connect it to any published popup form in your Mailmojo account, and 
visitors who click it will see the form immediately. It fits naturally into the 
block editor alongside your other content.
Turn your posts into newsletter content 
Enable content sync to push your published WordPress posts to Mailmojo and keep 
them in sync automatically. When you’re building a newsletter, Mailmojo’s content 
browser lets you drag and drop your latest posts directly into your email, no 
copying, no pasting, no reformatting.
<h3>External Services</h3>
This plugin connects to the Mailmojo API (api.mailmojo.no) to:
<ul>
<li>Verify your API token when you save or test the connection.</li>
<li>Fetch your account’s JS snippet, which loads subscribe popup forms on your site.</li>
<li>Retrieve your published popup forms for use with the Popup Button block.</li>
<li>Push your WordPress integration settings (site URL, username, and application password token) to Mailmojo when content sync is enabled.</li>
</ul>
No data is transmitted until you save an API token. Content sync credentials (site URL, WordPress username, and an application password) are only sent when you explicitly enable content sync.

This plugin provides the ability to configure WPSiteSync with an HTTP Authentication username and password to be used when communicating with a Target server that is set up with Authentication.
Usage Scenarios:
If you’re using WPSiteSync with a staging server but want to limit access to the staging server via HTTP Authentication, this is the plugin for you.
This add-on plugin for WPSiteSync allows you to configure an HTTP Authentication username and password that will be used in communicating with the Target server; allowing you to PUSH and PULL changes from your local site to your password protected staging site.
This plugin works the same whether your Source Site is a local install via DesktopServer or other local development environment, or a publicly hosted site. For more information on DesktopServer and local development tools, please visit our web site at: <a href="https://serverpress.com/get-desktopserver/" rel="nofollow ugc">https://serverpress.com/get-desktopserver/</a>
How it Works:
The WPSiteSync for HTTP Authentication add-on plugin sends the username and password with each API request made to the Target site. This allows you to configure your Target site with .htaccess rules that will limit access to user that have the password.

WPSiteSync for HTTP Authentication

It does what it says it does

It allowed me to configure my target site with .htaccess rules that will limit access to the user that has that password.

This worked like a charm.

Adds support for sites protected with HTTP Authentication via .htaccess rules.
