Use a mail formular for the Subscribe Button

The easiest way to embed a subscribe form in the Mashshare subscribe slide down box is to use a third party mailing plugin like “mailpoet” or contact form plugin like “contact form 7 (cf7)” and copy its integrated shortcodes into the Mashshare settings field for the subscribe button.

If you are using “mailpoet” this is an example code borrowed from including a Facebook like button.
You have to adapt this to your needs:

<div class="email-subscription"><strong class="title">Sign up and we notify you about new features and Add-Ons</strong>[ wysija_form id="1" ]<span class="note" style="font-size: 12px;">We promise not to spam you and not to give away your mail address. Read our <a href="/privacy">privacy policy</a>.</span></div>
<div style="float: left; padding-right: 10px; margin-top: 4px;"><strong class="title">Don't forget to like Mashshare: </strong></div>
<div style="margin-top: 10px;"><iframe style="border: none; overflow: hidden; width: 90px; height: 21px;" src="//;width=90&amp;layout=button_count&amp;action=like&amp;show_faces=true&amp;share=false&amp;height=21&amp;appId=317697668417910" width="300" height="150" frameborder="0" scrolling="no"></iframe>
<iframe style="width: 200px; height: 21px;" src="//;lang=en&amp;show_count=true" width="300" height="150" frameborder="0" scrolling="no"></iframe></div>
