What to use.
WHAT MATTERS
That submissions are stored, not only emailed Spam protection Mobile behaviour Weight it adds to your pages Whether it is maintained
THE STORAGE REQUIREMENT
A plugin that only emails submissions loses them when email fails.
Choose one that stores in the site database.
WHAT MOST SITES NEED
A simple contact form and perhaps a quote request.
A lightweight plugin suffices.
WHEN A HEAVIER PLUGIN IS JUSTIFIED
Conditional logic Multi-step forms Payment collection File uploads Integration with other systems
THE WEIGHT POINT
Many form plugins load scripts on every page of your site, not only the page with the form.
Check whether yours can be limited.
WHAT TO AVOID
Several form plugins installed with one actually used Unmaintained plugins handling user input
That second one matters. Forms process untrusted input, so an abandoned form plugin is a real risk.
