Build your own forms. Create a subscription form, a contactform, a form to register for an event, etc. You can even use your selfmade form as a webshop (albeit a simple one).
Design your form as you wish. Add text fields, number fields, choice menus, and on/off switches. Decide on the names for your form fields, give a description, and set a default value if applicable. Both you and the submitter can get a notification by email. And the submitted forms are all collected in one place.
Your forms are protected against spam and bots. You can even choose to block certain submitters by blocking email addresses and IP addresses. No form spam no more!
