Contact Form 7 was the first contact form plugin I used when I first got involved with WordPress. It worked well and I never had a problem with it. If all you need is a simple contact form, CF 7 fits the bill. For the longest time, this post from 2009 on how to configure it was the best performing post on the site https://wptavern.com/configuring-contact-form-7 it still gets traffic. I also received so many support emails, I had to update the post and close comments explaining I'm not the plugin author and don't do support.
