Adding a Google Plus (one or share) link to an email newsletter
EmailShareNewsletterGoogle PlusGoogle Plus-OneEmail Problem Overview
I am trying to find a way to embed a share/+1 link for Google+ in a Newsletter, much like the Facebook share and tweeter tweet links can be embedded in a newsletter, which can be achieved with the following two urls:
https://www.facebook.com/sharer.php?u=[URL]&t=[TEXT]
http://twitter.com/intent/tweet?source=sharethiscom&text=[TEXT]&url=[URL]
Is there a similar functionality available for Google Plus?
All I could find on my own, is the Google+ button, which unfortunately uses JavaScript and thus it cannot be used in an email newsletter. I would expect Google to provide a static url fallback, but I cannot find it anywhere.

Solution 1 - Email
https://plus.google.com/share?url=http%3A%2F%2Fexample.com
You can share the link on Google+ with the official Google+ share link.
Replace the url parameter with the URL encoded link you want to share.

This one works fine for me :
https://plus.google.com/share?url=your-page-url
Solution 3 - Email
The share link allows you to do this. It will work in an email, but it's not quite the same as the +1 button.
To use the share link, add a link element to your email that complies with the Google+ Buttons policy. Set the href attribute to https://plus.google.com/share?url={url encoded share target}
For example, linking to https://plus.google.com/share?url=http%3A%2F%2Fexample.com will allow you to share example.com on Google+: 
(yes, that is a working demo).
Check out the official docs for more info.
If you use this approach please be aware of the fact that it is not a direct replacement for the +1 button. The link shares the target URL on Google+, but it does not actually +1 the target page. Only the +1 button can +1 a page.

Solution for those who needs custom title, description and image. You should make following changes to target URL:
Step1. add itemscope itemtype="http://schema.org/LocalBusiness"; into <html> tag. It will look like <html itemscope itemtype="http://schema.org/LocalBusiness">. More itemtypes here
Step2. Place the follwing meta tags into <head>, change content attributes according your needs:
<meta itemprop="name" content="{Custom title goes here}">
<meta itemprop="description" content="{Custom description goes here}">
<meta itemprop="image" content="{http://www.your_url.com/your_image.png}">
Step3. Add the following link to your newsletter or anywhere you want:
<a href="https://plusone.google.com/_/+1/confirm?hl=en&url=http://www.your_url.com">Share it</a>
Tip. To check how google sees your page, you can use this tool http://www.google.com/webmasters/tools/richsnippets. Probably you'll be interested in section Extracted rich snippet data from the page

I personally suggest Google Plus Interactive Posts button https://developers.google.com/+/web/share/interactive to use in your apps/websites.Here Google Plus allows many customizations to do according to the requirement. I have used it in my app. Its a better option than Share button.

Maybe this helps. It works (partially) for me. http://www.stateofsearch.com/share-on-google-plus-any-website/

There has got to be a way to do this by hacking the +1 script.
If you are interested in just changing the apperance you should download and modify this to suit your requirements.
Then, add this to your css:
.Uu .KF {
background: url("your-replacement-image") no-repeat scroll -132px -21px transparent !important;
}
to override the Google icons. However, this is probably very unstable and subject to change.
