If you are seeing links in your newsletter test that you did not create, please understand that almost every email client (gmail, outlook, Apple Mail, etc.) will convert email addresses, phone numbers and URLs, to links even if they are not actively created as a link. 

When this happens, the email client automatically applies the default link color, blue, to all those links.

In order to work around this behavior, it is recommended that you manually create links in all your Content Boxes for any text that an email client will apply a link to such as

• email addresses
• phone numbers
• URLs

You can then apply link color as instructed in this FAQ:
