When you first open up the settings page, you will be greeted with 6 tabs:

  • Configuration – Basic functionality and settings
  • Comment Form – Specific settings for the Comment Form
  • Registration Form – Specific settings for the Registration Form
  • Signups – List of the last 25 signups via the plugin.
  • Export – Export a .csv file containing all details for the signups
  • Log – A log so you can view the progress and details of the functionality of the plugin.

Lets start with setting up the plugin. First go to the “Configuration” tab.

Under “Activate Functionality”, there are two checkboxes. By checking these on and off, you can control which functionality you wish to use.

To add the functionality to the Comment Form, make sure the “Enable Comment Form Signup?” checkbox is checked, and if you wish to enable this functionality during registration on your blog as well, you can use the “Enable Registration Form Signup?” checkbox.

Extra functionality

It is possible to have the checkbox next to the comment form pre-checked when people enter a comment, but please be aware, that this is not CAN-SPAM compliant, so use this functionality at your own risk!

Signup Filter Settings

Spam and spam comments are always a problem, and it is possible to filter out most of these, by turning on the “Ignore Suspected Spam?” option. This lets Newsletter Booster use WordPress’s spam detection functions, and if WordPress suspects the comment in question is spam, the user who left the comment will not be registered as a newsletter signup.

Only Approved Comments is the next step, where you can also set up Newsletter Booster to only sign up users who leave a comment that is approved directly. If the comment needs to be approved first (due to your blog settings or WordPress suspects the comment is spam) the user will not be signed up to your newsletter.

Email Notice Settings

Notify Admin? By turning on this option, you will automatically get an e-mail every time a new user signs up to your newsletter via the plugin.

Hide for your users? A nice little feature, that allows you to hide the checkbox for your registered users.

External API Integration

Newsletter Booster can submit your newsletter signups directly to external newsletter managers such as Mailchimp or AWeber. This feature requires a bit more technical insight, but two examples are provided in the plugin.

For more details and explanation, go to the section named “External API Integration Documentation” in the documentation.

Designing the signup

Newsletter Booster gives you the option of styling the design. Please note: Not all WordPress Themes looks fantastic without any tweaking of the design, but if you have a little bit of experience with HTML and CSS, it is not that difficult to tweak.

Go to the tab “Comment Form” to tweak the design.

Per default, the checkbox to sign up to the newsletter is put below the comment field, where it is not very visible. The option “Above Comment Field” can move the checkbox up above the comment field, but please note this functionality does not work that well with all WordPress Themes, and might require a bit of tweaking if it does not work when turned on.

Pitchline: Is where you can enter the text next to the checkbox, example: “Please sign me up to your newsletter also.”

Disclaimer text is an optional text field where you can enter text which is then displayed below the checkbox and pitch line. HTML is accepted, for example:

To make the option of signing up to your newsletter stand out, you can use the “Highlight Setup” option. By turning on this option, you will be able to fill in HTML in the “Before NLB code:” and “After NLB code:” text fields, to make visually appealing signup notices.

External API Integration Documentation

One of the most powerful features in Newsletter Booster is the integration with any external mailinglist manager system that allows for adding newsletter subscribers via URL strings.

For example, if you wish to add a new e-mail and name to a mailing list hosted with Mailchimp, you can turn on the option to send this information in the settings page of Newsletter Booster in the tab named “Configuration” in the section named “External API Integration”.

If you turn on the option “Submit to API”, every time a new newsletter signup is processed and approved based on your other settings, Newsletter Booster can open an URL with the correct parameters added automatically.

To use with Mailchimp:

Please note the YOUR_API_KEY and YOUR_LIST_ID needs to be filled out with YOUR specific values. Both values can be found in Mailchimps system after you have logged in. Specific links to Mailchimps own documentation:
