The AddToAny WordPress plug-in is a great tool, makes it very easy to share any web page on your website.
The email button can be problematic though. In some cases only a blank page is opened, and the error message “Please copy & paste if the app did not open:” shows up.
To work around this problem I recommend turning on the “Universal Email Button” feature of AddToAny. This will bring up a menu that allows the user to select “Google Gmail”, “Outlook.com”, “Yahoo Mail” etc.
First, visit the AddToAny settings page on the WordPress Dashboard (Settings > AddToAny). Scroll down to the “Additional JavaScript” section, expand it, and enter in the following code:
var a2a_config = a2a_config || {}; a2a_config.menu_type = "mail";
Click on “Save Changes” at the bottom to save the changes made.
From now on the “plus” button will bring up the email selection options.
