Hi there, Giovanna Tucker thank you for submitting to our Ucraft Forum!
You can add AWeber to your website with the help of our Custom HTML Element or through the Site Settings App > Code Injection section. Just keep in mind that to have it active you'll need to connect a Custom Domain to your Ucraft site first.
We also suggest using this article for a step by step guide on how to get the HTML code from AWeber.
Feel free to let us know if anything else is needed!
