SendGrid Mailing List


This plugin is a very basic simple plugin that utilizes the API to
be able to have users enter their email to a particular recipient list.

Currently does not have a html web form widget to allow users to
embed a subscription form on their website. This plugin provides a simple form
with just Email Address and a go button. You specify your List Name, and your
API Username / Password in the settings file.




By default the short code will take options set in the plugin options


  • Specify List: [sg-subscription-form list='Mailing List']
  • Redirect to URL After Success: [sg-subscription-form redirect='']


  • Settings Screen


  1. Activate the plugin through the Plugins menu in WordPress
  2. Go to Settings->SendGrid Mailing List and enter in your Recipient List name, API Username and API Key. (These are the same credentials that you login to with)
  3. You can then place the shortcode [sg-mailinglist] in a widget area or directly in a page/post to display the subscription form.
