Interesting in using jetpack subscription widget

You should be able to customize the look of the form with CSS to match the Feedburner widget’s style. You can add that CSS to your theme stylesheet, or to your custom CSS editor available under Appearance > Edit CSS in your dashboard.

If you’re not comfortable writing this CSS on your own, I’d be happy to tell you what code to use, but I would need you to add the widget to your sidebar again so I can test my CSS changes.

Thanks!

Something like this should do the trick:

.sidebar .jetpack_subscription_widget form {
  margin: 0;
  width: 261px;
  padding: 5px 15px;
  float: left;
  border: 1px solid #bfbfbf;
  border-top: transparent;
  border-bottom: transparent;
  background: #FFF;
  margin-left: 5px;
}

.sidebar .jetpack_subscription_widget #subscribe-text {
	text-align: center;
}

.sidebar .jetpack_subscription_widget input[type="submit"] {
	margin: 0 80px;
}

.sidebar .jetpack_subscription_widget #subscribe-email input[type="email"] {
  background: url(http://www.jumzler.com/wp-content/themes/caresland-lite/images/input-bg.png);
  width: 241px;
  height: 21px;
  border: none;
  box-shadow: none;
  background-repeat: no-repeat;
  color: #292929;
  font-size: 14px;
  font-family: 'Scada', sans-serif;
  padding: 13px 10px 7px;
}

You can paste that code at the end of your theme stylesheet, or in your custom CSS editor.

I hope this helps.
