Your labels have a for attribute but your inputs do not have a matching id. This is required to get them to work together. See the link below for a more in depth explanation.

Here is a working version of your code:

.preferences {
  height: 103px;
  width: 491px;
  box-shadow: 0px 12px 18px -6px rgba(5, 5, 5, 0.3);

  font-size: 16px;
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
}
input {
  display: none;
}
span {
  height: 15px;
  width: 15px;
  border: 1px solid grey;
  display: inline-block;
  position: relative;
}
[type=checkbox]:checked   span:after {
  content: '\2714';
  position: absolute;
  top: -5px;
  left: 0;
}

<div >
<h2>I prefer</h2>
<label for="prefer-email">
<input id="prefer-email" type="checkbox">
<span></span>Send me an email
</label>

<label for="prefer-call">
<input id="prefer-call" type='checkbox'>
