Level: Basic
A contact form's job is to make it as easy as possible for an interested visitor to actually reach out, and every unnecessary field works against that goal.
Ask for Only What You Genuinely Need
Each additional field increases the chance a visitor abandons the form before completing it, so every field should earn its place.
Make Required Fields Obvious
Clearly marking which fields are required, rather than leaving visitors to guess, reduces frustration and form-submission errors.
Confirm Successful Submission Clearly
A visitor should never be left wondering whether their submission actually went through; a clear confirmation message or page closes the loop.
