If you are looking for a simple solution it doesn't get much easier than fwdform. I wrote it myself when I needed quick and dirty contact form processing on my own static site.
To get your form forwarded to your email you just need to do the following.
1.Register
Make an HTTP POST request to register your email.
$ curl --data "email=<your_email>" https://fwdform.herokuapp.com/register
Token: 780a8c9b-dc2d-4258-83af-4deefe446dee
2. Set up your form
<form action="https://fwdform.herokuapp.com/user/<token>" method="post">
Email: <input type="text" name="name"><br>
Name: <input type="text" name="email"><br>
Message: <textarea name="message" cols="40" rows="5"></textarea>
<input type="submit" value="Send Message">
</form>
You can even run it on your own Heroku instance if you prefer not to trust a third-party service.
