What it does

The MailUp plugin for WordPress makes it easy to ass a customizable newsletter signup form to a WordPress Web site.

  • Visitors to your WordPress-powered blog or Web site will be able to subscribe to your newsletter using a configurable sign-up form. Their information will be saved in your MailUp account.
  • You will use your MailUp admin console to manage those subscribers, create and send messages to them, view statistics on sent messages, and more.
  • The MailUp plugin supports the recommended 'confirmed opt-in' subscription method (i.e. subscriber receives an email with a confirmation link that has to be clicked to confirm the subscription). This method ensures that spam traps or wrong email addresses are never added to your list.
  • The unsubscription process will be managed automatically by MailUp (e.g. unsubscribe link in the footer of your messages).
  • MailUp supports SMS (text messaging) too, so you can choose to collect a mobile phone number as well.
  • It also supports sign-up via a social networking account (additional fees apply: see the MailUp web site for details).

How to use it

MailUp and WordPress make it easy to create a Web site and a blog, and to communicate with readers or site visitors through a newsletter.

  1. Signup for a free trial (no credit card required): English /  Italiano
  2. Create one or more Lists (e.g. two WordPress sites: you will create two Lists in MailUp).
  3. Install the plugin in your WordPress admin area, as described below
  4. Configure settings such as the header, footer, message templates, confirmation request email, welcome message, etc.
  5. Visitors to your Web site will start signing up, and you will be able to track the subscription trend over time in your MailUp admin console.
  6. Create and send email and/or text (SMS) messages to your subscribers.
  7. Use the NEW MESSAGE FROM RSS feature to create a newsletter from RSS feeds (a list of recent articles from your WordPress-powered blog). Just select the posts and choose a template and priority. You will be able to edit the newsletter after it has been automatically created, before you send it, without any copying and pasting.
