On the iPhone and iPad, you may encounter links for telephone numbers, dates/times, and addresses. You can disable/hide this by adding the following in the head tags of your message.

<meta content="telephone=no" name="format-detection">
<style type="text/css">.appleLinksWhite a {color: #ffffff !important; text-decoration: underline;}
.appleLinksBlack a {color: #000000 !important; text-decoration: none;}
</style>

Then around each blue link in your message add the following class: class="appleLinksBlack"

Here is an example
<span class="appleLinksBlack">May 16, 2017</span>
