There are many ways to add padding to your text block in Mailchimp, but I am going to share two quick ways for people who don't want to deal with code.
#1 Use "Boxed Text"
#2 Use a tiny bit of HTML which you can cut and paste into a text block:
β
<table align="βcenterβ" border="0β" cellpadding="10" cellspacing="0" width="β600β">
<tbody>
<tr>
<td style="text-align: left;">Your text here</td>
</tr>
</tbody>
</table>
