Newsletter HTML Generator plugin extracts title, teaser (or excerpt), author name, featured image, permalink, shortlink, date from current post and generates full HTML-code of ready to send newsletter based on the templates you provide. You just copy and paste the final HTML-code in your favorite newsletter sending service like Mailchimp, GetResponse, Campaign Monitor, etc.
<h3>How does it work?</h3>
The plugin makes custom post type “Email Templates”. 
1. First, you create as many templates as you need (for example “Mailchimp responsive”, “Weekly newsletter”, etc). You can get templates from newsletter service or design your own. 
1. After that you open any of your regular posts in edit-mode, and choose any Email template you created before. The plugin instantly generates ready-to-send HTML-code using the post’s title, teaser, etc. You also get the plain-text version of your newsletter – just in case.
The plugin doesn’t send newsletter, doesn’t create signup forms, doesn’t segment your subscribers! It only generates ready to send HTML you can use with ANY Email service provider or Email marketing service.

Display “Badges” in the side-panel which points to a web-site and an image which is then used to build the “badge”.
To access the configuration you have to go to Appearance > Widgets and edit the settings in the Panel.
Using the Widget you can choose whether to:
<ol>
<li>(Optionally) display a Title</li>
<li>Link to a site</li>
<li>Required link to an image to mark that site (any size will work, but the “standard” seems to be 88 pixels wide by 31 pixels high)</li>
<li>Pad the Badge (including centring the text); some people may prefer using their own CSS, so this is an optional configuration.</li>
<li>Enable “Display Badge in a Box” (enabled by default)</li>
<li>Enable the Displaying of a Drop-Shadow</li>
</ol>
If more control is needed, or more badges need to be displayed, the <a href="https://wordpress.org/extend/plugins/badges/" title="Wordpress Plugin" rel="ugc">badges plugin</a> on the WordPress site might be a better fit.

Badge

Display a badge (based the "badges") without requiring file-system access or knowledge of HTML.
