Depending on your ability to edit the website code, there are three possible scenarios to add the MailBluster form to a WordPress site:
1. If you manage your website’s code, you can add it there yourself. Inline forms should go inside the body tag wherever you want to display the form. Pop-up forms should go just before the closing body tag.
2. If your website has a dedicated webmaster or web admin, you can forward the code to them, and they can publish the form for you.
3. If you created your website using a builder tool, you could contact the support of your website builder to ask for instructions specific to their tool.
