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.
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 https://www.site24x7.com/find-ip-address-of-web-site.html
|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 host
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”
Text used for the submit button
Select preloaded CSS for widget
Select one of four predefined styles. 
|Use placeholders instead of labels||If checked, placeholders inside recipient fields will be used to display the names of the fields|
|Request confirmation by email|
Asks new subscribers to confirm their subscription via email (recommended)
|I am using WPML to translate this website||Check this option if your Wordpress site uses WPML or Polylang for multilanguage support.|
 You can change the style of the sign up form as shown here.
The last option is useful if your Wordpress site uses WPML or Polylang for multilanguage support. By checking this box, each text string configured in the MailUp plugin will be added to the Wordpress strings DB shared by all plugins. The translation plugins will retrieve the strings from this DB and allow to translate them, so that language selection made by the user at site level will also be reflected in the subscription form configured with MailUp's Wordpress Plugin.
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 eight 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 six fields can be associated with any of the additional fields used in your MailUp console under "Manage > Personal Data Fields". Please note that one of this six additional fields is a date picker, so this particular field can only be used to send a date (in US format, mm/dd/yyyy).
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 add up to two conditions the subscriber has to accept in order to subscribe the form. Enabling one or more conditions is optional.
In the widget panel, the submit button requires you select all the enabled conditions to proceed.
In the example below two conditions are enabled, only the for the first one an additional text is provided. Please note that basic HTML can be included in the textarea field to link to an external document
|Admin panel||Frontend widget|
You can use the "Test" button to instantly verify the plugin settings you've configured, so that you are immediately aware if there is an IP addresses restriction configured in MailUp, or if an incorrect IP-based restriction set in MailUp is preventing the plugin to communicate with it.
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 (full account or a free trial) and then specify the platform 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 the IP address of your server. More than one address could be registered).
Go to the 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 Test button. If the test is successful, try to subscribe to an address from the form. The specified contact will be added to the MailUp distribution list specified in system settings.
Yes, you can modify any of the sections ("General Data", "User Lists", "User Fields", "Errors" and "Terms and Conditions") and update the information.
You can select between four (4) available styles (CSS), if no one matches your need you can edit one of the existing CSS files (style1.css, ..., style4.css). Please note that editing is allowed only for users who have read/write access to those files.
Yes, MailUp provides a simple integration with all the most used social networks. You could insert into your website a simple banner "Click here to subscribe to our newsletter using your Facebook account". This feature is a standard one and you don't need to install any plugin, just activate a MailUp account.
Yes, edit each string within the settings panel. No need to edit any file. MailUp supports all the charsets. If you use WMPL or Polylang to manage multilanguage, check the corresponding option inside General Settings.
MailUp allows you to take control of subscribers (view, import, edit, delete, export) and of messages (define scheduling, content, and recipients).
Yes. Click on the Plugins tab and click on "deactivate."
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.
Yes. You have to create the subscription form extrapolate the HTML code and paste it inside WordPress during the creation of an article or page (this depends on the theme used or the website set up).
