1) Manual solution:
Create a coupon with your desired rules
Set the number of uses to 1 per customer and unlimited for general usage.
Copy the coupon code in the newsletter email
Path: app/design/frontend/{your package}/{your theme}/locale/language_ISO/template/email/newsletter_subscr_confirm.html for exemple.
2) The dynamic one:
Create an observer on the newsletter_subscriber_save_before or newsletter_subscriber_save_after that checks if the customer subscribes and if so, it creates a coupon with your desired settings. See this for creating coupons by code.
Then rewrite the method Mage_Newsletter_Model_Subscriber::sendConfirmationSuccessEmail so you can pass that code as a parameter to the e-mail template.
Something like this:
$email->sendTransactional(
Mage::getStoreConfig(self::XML_PATH_SUCCESS_EMAIL_TEMPLATE),
Mage::getStoreConfig(self::XML_PATH_SUCCESS_EMAIL_IDENTITY),
$this->getEmail(),
$this->getName(),
array('subscriber'=>$this, 'coupon_code'=>THE COUPON GENERATED IN THE EVENT)
);
Then modify the newsletter subscription e-mail template to include this:
Your coupon code is: {{var coupon_code}}
Reference.

So after the some action the customer gets the email with the code.
I assume in the code it's a controller action.
What you need is to add a view for this action (block and template) and in the template show generated coupon code. And the coupon generation function you already have in the module.
