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
Connecting WordPress to MailUp
Do I have to be a MailUp customer to use the plugin?
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).
How can I configure my plugin?
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.
How can I check if my plugin is working?
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.
Once the configuration is setup, 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 with your need you can edit one of 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 to 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 web site a simple banner "Click here to subscribe to our newsletter using your Facebook account". This features 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.
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 of messages (define scheduling, content and recipients).
Can I disable the plugin?
Yes. Click on the Plugins tab and click on "deactivate."Configuration seems to be correct
The plugin was configured correctly, butplugin always
it still returns a "generic error"message.Starting from v.7.4, MailUp introduced a security restriction that allows only calls from servers whose IP address is registered on MailUp console (go to "Manage->Web service" and then select "frontend" in the dropdown menu to start registering IP). More than one address could be registered. Even if it is not recommended, you can disable this restriction by deselecting "IP address check enabled" option
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.
