With the MailUp plugin you can easily add a newsletter sign-up form to your Web site or blog, and then send and track email and sms with MailUp. The MailUp newsletter signup plugin for WordPress is available free of charge in the WordPress Plugin directory.
The MailUp plugin for WordPress makes it easy to add a customizable newsletter signup form to a WordPress Web site.
MailUp and WordPress make it easy to create a Web site and a blog, and to communicate with readers or site visitors through a newsletter.
See the video tutorial above for an overview. Here are detailed instructions:
Sign-in to your WordPress admin account from your website or blog.
View the Plugins tab and Click on “Add New.”
Search for the "MailUp" plugin on the search tab
Click on “install now.” and click "yes" to confirm.
Click on "Activate plugin."
Go to the the Appearance section and click on the widgets tab. You can see all the available widgets including the MailUp one.
Drag the MailUp widget into the main sidebar.
You can now go to your website and check that the MailUp newsletter plugin is installed.
Before you can connect your WordPress site to your MailUp account by filling out the fields on the setup page, you will need to activate the MailUp API in your MailUp account:
To find out the IP address of your Web site, you can use a service such as http://websiteipaddress.com or http://www.selfseo.com/find_ip_address_of_a_website.php
|If after completing the setup you keep getting a "Generic Error" when testing the subscription form, try disabling IP address validation in your MailUp console.|
After installing the plugin and authorizing an external connection to your MailUp account, access the WordPress administration panel and select Settings > WP MailUp in the left-side navigation menu to configure the plugin.
The setup page will be displayed.
Continue with the steps below, starting with adding your MailUp account credentials to the General Settings tab
Configure the settings in each section as described below. Please note that all the data required to configure the plugin is available in your MailUp console under "Settings > Codes Table".
Use this section to configure general properties, including the MailUp account URL, form title, etc.
MailUp console URL
Subscription page name and path (do not modify this entry)
Subscription form title shown where the widget is placed
"Sign up for our newsletter!"
Text shown under the title
“Enter your information and press Sign Up”
Select preloaded CSS for widget
Select one of four predefined styles. 
Text used for the submit button
Request confirmation by email
Asks new subscribers to confirm their subscription via email (recommended)
 You can change the style of the sign up form as shown here.
Select which List in your MailUp account the new subscriber will be added to. MailUp accounts support multiple lists, but you can only add site visitors to one List (and optionally one Group within the List) using this widget.
List ID (REQUIRED)
Numeric list identifier. You can locate the ID in your MailUp console under "Settings > Codes Table".
List displayed name (NOT REQUIRED)
Not currently in use
Group ID (NOT REQUIRED)
Numeric Group identifier within the list. You can locate the IDs in your MailUp console under "Settings > Codes Table".
The subscription form can pass up to four separate pieces of information to MailUp. Either the email or the mobile phone number must be sent to MailUp for the user to be added to the system, so you must make at least one of those two fields required. The other two fields can be associated with any of the additional fields used in your MailUp console under "Manage > Personal Data Fields".
Here is how the plugin looks by default on customer-facing pages:
Here you can edit the error messages that are shown when the submit button is pressed, if there is an issue.
“Thank you for subscribing to our newsletter. Check your email to confirm your subscription.”
“There was an issue. Please try again.”
“The email address is not valid”
“It looks like you're already a subscriber!”
You can display terms and conditions of the subscription so that the new subscriber can have the opportunity to review them and agree to them.
Include acceptance of terms and conditions
If active, a checkbox is shown and is required.
Terms and conditions
Enter the terms and conditions.
Enter the statement that will be shown next to the checkbox (e.g. "I agree to these terms"
You can include basic HTML in the textarea field to link to an external document, as shown in the screen shot below.
You can customize the look of the subscription form created by the plugin in your WordPress-powered Web site by either changing the CSS style selected under General Settings as mentioned above, and/or by further editing those cascading style sheets. Familiarity with CSS is required to manually edit the default styles. Here is how to do so:
The form is identified by the selector “#subscribeForm” in the CSS document.
|Make sure that any style you add or modify uses the “#subscribeForm” selector to avoid any conflicts with other styles, which could negatively affect the rest of your Web site|
You must have activated a MailUp console (a regular one or a 30 days trial) and then specify console URL in plugin settings. On MailUp you must enable requests coming from the server that hosts your WordPress site (go to "Manage->Web service" and then select "frontend" in the dropdown menu to insert IP address of your server. More than one address could be registered).
Go to admin panel, press "Settings" and then select "WP MailUp". Fill in or check all the fields using the help buttons if something is not clear.
Just fill in the required fields and press the SEND button to subscribe. The specified contact will be added in the MailUp distribution list specified in system settings.

The IP address of the Web site or blog is probably not registered in your MailUp console. See above under "Authorizing WordPress to communicate with MailUp". If you are still getting this generic error even after correctly registering the blog or Web site's IP address, please try disabling IP address validation in your MailUp console and try again. There are times when IP address validation does not work properly and it can cause this issue.
