also in your mobile site title html you put:
<font color="#000000"><p style="font-family: Helvetica"><font size="5.5"> <b> CHRISTIN </br>
BÜTTNER</font> </p></b></font>
but it should be:
<font color="#000000">
<p style="font-family: Helvetica">
<font size="5.5"> <b> CHRISTIN </br> BÜTTNER </b></font>
</p>
</font>
so here i think just the position of the closing </b> tag was wrong.
i fixed these things for you and now the website looks normal again.
when writing your own html please be careful as you can break things if you write it wrong

how can i add a Mailto-Link?
i think if you add a text, then in the texteditor click the "link" button, then as the link enter:
mailto:hey@mail.com
