Hi Ted , thank you for your reply!
Do you mean emailing with a form? In that case it would help to contact this plugin developer. I don't think this is an issue with Buttonizer.
If you mean the email
button action, that's something that is configured by the owner of the device. For example, if you have set the button action and someone with Windows opens it, it will try to open Outlook or any other default email application. When that hasn't been set, it won't open any dialog.
If an email hasn't been sent from the visitor side via Outlook for example, then they've misconfigured their own email environment. That isn't something we can do unfortunately.
Let me know if this helps 🙂
