Keep in Touch

Offers a widget that enables visitors to subscribe for receiving by email a weekly digest
of newly added posts. This keeps the users closer to your site and doesn’t force them to
“poll” for updates.

The widget only shows an input field for the email address and a ‘Subscribe’ button.
Then a short procedure is started to confirm the subscription:

• No validation is performed on the entered email address.

• After clicking on ‘Subscribe’, the user is presented a virtual page in which she is
  asked to re-enter the email address and click again on a ‘Subscribe’ button.
  This is a simple measure against robots placing subscription requests.

• Again, no validation is performed on the entered email address except it is matched with
  the one previously entered. In case of a match, an email message is sent to the user
  containing a link with a unique code, on which the user has to click to confirm her
  request. The user is informed by this in a new virtual page.

• After the user clicks on the link in the email, the email address is considered
  subscribed and it will receive weekly messages containing a digest of new posts from the
  previous week, with direct links to the respective pages. In each message there is also
  a link to allow the user to unsubscribe.

Unsubscribing follows a similar pattern in which the user will first receive an email to
confirm the request, with a link containing a unique code.

To keep it simple, no check is performed as to whether a user is already registered or
not. Any request can be performed in any phase of the process.

Weekly emails are sent using wp_mail(), on a configurable weekday at a configurable time.
Even when no posts have been added, the user will still receive and email to inform her of
that.

The emails will all contain the heading image of the theme at the top.

Until support is provided for selecting subscriptions, all subscribers will be subscribed
for the weekly digest and the newsletter.

Warning!

Only tested with the permalink format set as
“/index.php/%year%/%monthnum%/%day%/%postname%/” on a Windows server. Don’t know if it
works with other formats, although the implementation is quite generic.
