There is now a function for Subscribing via an Email.
The address the email has to be sent to is available at the top of the page which also includes the Optin Form HTML Code for a standard Optin Form, as below. Lists > Overview > Forms
In Forms you will find
You place a Mailto: URI Link on your web page using the following HTML code
<a href=“mailto:firstname.lastname@example.org?subject=subscribe”>Click to Subscribe</a>
and replace email@example.com with the email address from the List > Overview > Forms page as illustrated in the screen shot above.
The alternative code to Unsubscribe, should you ever need it, is
<a href=“mailto:firstname.lastname@example.org?subject=unsubscribe”>Click to Unsubscribe</a>
That will appear on your web page as a simple clickable link Click to Subscribe so you will have needed to precede it with some suitable text such as – To receive our Free Newsletter please just click the the following link – or whatever suits the situation.
Or in the HTML code you might like to modify the link text from Click to Subscribe to – Click to receive our Free Newsletter.
Also very useful if used in cunjunction with one of the many Shopping Carts that facilitate sending an email to any designated Email Address when someone makes a purchase, thereby adding the purchasers Email Address your List in SR.
