Instead of clicking on a link to send you an email I would suggest that you avoid any mail setups that create more manual work for you. To make something of your site you should automate as much as possible, and ensure you have the best delivery rates for all your email.
Nowadays in this spam-challenged world, unless you run your own server with dedicated IP address, you want to avoid handling mail from your web server or being sent direct ly by you through your local ISP's mail server. In doing so, you will avoid mail throttling, poor mail reputation from shared IP addresses, and buggy and inflexible mail solutions etc.
As such, inbuilt mailout plugins are IMHO not a very good solution anymore unless you are combining the with a external SMTP mail service like Sendgrid. I haven't used a mailout plugin for over 10 years as there are too many downsides and I get more flexiblity with Mailchimp and their API.
Mailchimp is a mail and templating service. http://eepurl.com/WL8n5
It is free for the first 2000 addresses and 12000 emails per month.
You integrate Mailchimp using a Joomla Mailchimp plugin, linking your chosen mailchimp list(s) to the site. Different Mailchimp plugins provide different levels of integration options. You can use them to place newsletter sign-up modules, or auto add to lists on member registration etc. just as you would with an ibuilt mailout plugin. And combined with a code plugin like Sourcerer (which allows you to easily place raw code anywhere you want on your Joomla site), I find that you can get much essentially almost limitless flexibility in customising your own sign-up forms and boxes.
And, as stated, ensure good delivery rates for your outbound web server system emails using a free Sendgrid account http://sendgrid.com.
