If you are adding a link into your email, for example a link for an offer, it is possible to change the colour of the link to match the design of your email. This works for (hyper-) links as well as special links.
Below you can see an email as an example, with two different links; one email address (hyperlink) and one offer-link (special link).
Click into the text box and a layout menu will appear on the right. Here you will see the option "Link colour" (see image).
Fill in the colour code you prefer and the colour of the link will change. It is important to repeat this adjustment in every row. If you want all of your email links to be in the same colour, you will have to use this method for every text box. You can also save the row with the right coloured link and you will have easy access to it every time you are writing an email.
