With the MailUp for WordPress – Email and Newsletter Subscription Form plugin you can create a subscription form on your WordPress website or blog and let your visitors subscribe to your email and SMS campaigns.
This plugin aims to:
- simplify data collection and database management operations, and
- automatically connect your MailUp platform with your WordPress website
All the data entered by users in the form are automatically saved in your MailUp account. You can send your email and SMS campaigns to all the users who have subscribed through the form directly from your MailUp platform.
This plugin allows you to create and customize your subscription forms in every detail: title, description, subscription button, form fields, terms, and conditions.
The MailUp plugin for WordPress simplifies the addition of a registration form on a WordPress site and the collection of recipients for email and SMS campaigns.
Connect your MailUp account to WordPress, select a list and start designing your ready-to-use registration form.
Installing the MailUp Plugin for WordPress
- Download and install the plugin from the WordPress directory https://wordpress.org/plugins/mailup-email-and-newsletter-subscription-form/
- Connect MailUp account
- Log in with your MailUp credentials (username and password)
Now that you have connected your MailUp account with WordPress, you have to build your form.
Configuring the plugin
In the general settings you will find:
List: choose the MailUp list in which you want to collect your recipients
Group: give a name or select the group in which you will find your new subscribers
Title and description of the form: tell your visitors why they should fill out your form
Button Text: customize the text of the subscribe button
In the Form Fields tab, you can add and remove form fields. For each field, you can decide in what MailUp recipient field should the information be written, what type of content, the label displayed, and whether the field is mandatory or not.
The Terms and Conditions section gives you the ability to add up to three custom fields. Each condition will automatically create a dedicated group in your MailUp account so that you can easily retrieve who accepted them and create your marketing campaigns.
In the Advanced Settings tab you can, first of all, decide if people who sign up should receive an email requesting confirmation. You can customize some feedback messages and decide whether to use placeholders instead of labels.
Your form will inherit your WordPress styles. But if you want to customize it further, use the Custom CSS section.
How to use the form
After creating and customizing the form you can:
- place it wherever you want using the shortcode: [mailup_form]. Note that you can only have one form per page.
- Add it to the sidebar by activating a new Widget. The form will inherit your WordPress styles.
Is it possible to use the plugin for multi-language sites?
Yes, the latest version of our plugin is fully compatible with WPML.
Do you have the old version of this plugin?
Introducing the MailUp Plugin for WordPress
The MailUp plugin for WordPress makes it easy to add a customizable newsletter signup form to a WordPress Web site. 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.
- Visitors to your WordPress-powered blog or Web site will be able to subscribe to your newsletter using a configurable sign-up form. Their information will be saved in your MailUp account.
- You will use your MailUp platform to manage those subscribers, create and send messages to them, view statistics on sent messages, and more.
- The MailUp plugin supports the recommended 'confirmed opt-in' subscription method (i.e. subscriber receives an email with a confirmation link that has to be clicked to confirm the subscription). This method ensures that spam traps or wrong email addresses are never added to your list.
- The unsubscription process will be managed automatically by MailUp (e.g. unsubscribe link in the footer of your messages).
- MailUp supports SMS (text messaging) too, so you can choose to collect a mobile phone number as well.
How to use it
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.
- Signup for a free trial (no credit card required): English / Italiano
- Create one or more Lists (e.g. two WordPress sites: you will create two Lists in MailUp).
- Install the plugin in your WordPress admin area, as described below
- Configure settings such as the header, footer, message templates, confirmation request email, welcome message, etc.
- Visitors to your Web site will start signing up, and you will be able to track the subscription trend over time in your MailUp admin console.
- Create and send email and/or text (SMS) messages to your subscribers.
- Use the NEW MESSAGE FROM RSS feature to create a newsletter from RSS feeds (a list of recent articles from your WordPress-powered blog). Just select the posts and choose a template and priority. You will be able to edit the newsletter after it has been automatically created, before you send it, without any copying and pasting.
- MailUp automatically manages the unsubscribe process and gives you access to statistics down to the individual recipient level (opens, clicks, social sharing, etc.)

Potential issue with IP address validation
Connecting WordPress to MailUp
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)
The subscription form title is shown where the widget is placed
"Sign up for our newsletter!"
Text is shown under the title
“Enter your information and press Sign Up”
Text used for the submit button
Select preloaded CSS for the 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 the 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.
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".
Personal Data Fields
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 these 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).
- Check "Show" to show the field in the widget
- Check "Req." to make the field required
- The field code must match a valid field code in your MailUp console. "Email" and "SMS" should not be altered. The other field codes can be any of the field codes available in your MailUp console, and they can be located under "Settings > Codes Table".
- You can use as few as 1 field and as many as 8 fields. In the example below, 5 fields are used.
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!”
Terms and conditions
You can add up to two conditions the subscriber has to accept to subscribe to the form. Enabling one or more conditions is optional.
In the widget panel, the submit button requires you to select all the enabling conditions to proceed.
In the example below two conditions are enabled, only then for the first one, an additional text is provided. Please note that basic HTML can be included in the text area 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 is set in MailUp is preventing the plugin to communicate with it.
Customizing the default CSS styles
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:
- First, select the Plugins Editor in the WordPress administration area
- Select “WP-MailUp” from the drop-down menu
- A list of files will be displayed, including 4 CSS documents: “style1.css”, “style2.css”, “style3.css”, “style4.css”. They correspond to the following styles shown in the drop-down menu under General Settings:
- style1.css = Default
- style2.css = Rounded corners
- style3.css = Rounded black
- style4.css = No style
- Select a file to modify it.
- Click on "Update File" to save your modifications. We recommend that you backup the code before making any changes. If you don't see the "Update File" button, you probably don't have sufficient permissions in your WordPress installation. Contact your WordPress site administrator.
The form is identified by the selector “#subscribeForm” in the CSS document.
- Note that the changes are immediately live in your WordPress site if the document you edited corresponds to the style currently selected under General Settings.

FAQs and Troubleshooting
Do I have to be a MailUp customer to use the plugin?
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).
How can I configure my plugin?
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.
How can I check if my plugin is working?
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.
Once the configuration is set up, can I make any changes/updates?
Yes, you can modify any of the sections ("General Data", "User Lists", "User Fields", "Errors" and "Terms and Conditions") and update the information.
How can I change the appearance of the plugin?
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.
Can subscribers sign-up for my newsletter through a social account (e.g. Facebook)?
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.
Is it possible to translate this plugin?
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.
Why should I use this plugin and not other services, like FeedBurner?
MailUp allows you to take control of subscribers (view, import, edit, delete, export) and messages (define scheduling, content, and recipients).
Can I disable the plugin?
Yes. Click on the Plugins tab and click on "deactivate."
The plugin was configured correctly, but it still returns a "generic error" when I fill out the subscription form. Why?
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.
Can I insert the form within a single page?
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).
Is it possible to create a shortcode?
Yes, it is. First, you have to create the subscription form in your MailUp platform and extract the HTML code from using the dedicated button. Then you can associate the HTML code to a shortcode. There are various free plugins downloadable from WordPress that allow creating shortcodes using the HTML code of a subscription form.
Is there a possibility to link MailUp plugin to Elementor forms?
For the moment we do not have a direct plugin for the Elementor component of WordPress, but through the functions of the Elementor plugin, and by creating the registration form in Mailup, you can add the registration form to your website. First of all, you have to load the Html block from Elementor:
Then log into MailUp and create your subscription form. Find the subscription forms directly in the console, in the menu "Database building/Subscriptions/Subscription forms". Once created, the Html code can be obtained and copied, and pasted into the Html block:
In this way, you can have the registration form on your site directly linked to MailUp.
