Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters. Its similarly annoying to them when its a long free text box, making the customer question whether they are answering correctly and sufficiently. Providing response boxes that reflect the anticipated answer length and format reassures people that they are filling them in correctly.
Let people know what happens next. Having gone to all the trouble of filling in your form, the least you can do is provide users with information about what happens next. Customer communication is key, and since you have made the form so easy to fill in and return, processing it could also be a breeze!
Use appropriate response mechanisms. Paper forms have the disadvantage that users can miss, or simply disregard, an instruction. For example, only tick/check one box from a list of 15 or 20 options. In this context interactive forms can be programmed so that the user can only tick/check one (known as a radio button as distinct from check-boxes), or presented with the options in a drop-down menu from which the user can only select one. When designing forms make sure the response mechanism is appropriate to each question.
