How do I fill out a form that came to me in an email?

I am not quite sure what you mean, but based on the subject, I presume that someone sent you an email with the form or the link to it?

If that is true, than you can click on that link to fill it out.

If not, feel free to copy - paste the contents of the email here and we would be happy to assist if we can.

If you meant something else, please do let us know in more details in regards to the same.
