The last section when creating a new email list is the Signup Forms section. You can embed a signup form right onto your website to have clients sign up for your campaign.
Click "New Signup Form" and choose which type of signup form you'd like to make. You can choose from:
Form, which will create a generic form to collect information.
Pop-up, which creates a pop-up box prompting your client for their info.
Bar, which creates a bar that goes across your site that prompts your client for their information.
For each of these options, you can edit the way they look and feel on your website. You can customize the layouts, fonts, colors, and more for each type of form. You can live preview what it would look like on the right side of the editor page.
After you create your desired message, click on the "Embed Code" box right next to your form. You can copy the script form and paste it directly into a code block on your website.
