I am working on the confirmation email template with the WordPress Admin > MailPoet > Emails section

The brand design that I need to implement for the client features a pastel green 2px border running down either side of the page of their communications and 20px in from the edge of the page.

I have managed to write some source code in the H1 elements and the Paragraph element beneath but I can seem to get rid of the margin/padding top and bottom of each element so that the borders run seamlessly down the page, even when I use the !important tag to override any other formatting.

Are you able to provide me with a solution for this?

Here is the current code for the H1 section including parameters to adjust padding and margins:

    [site:title]

… and the paragraph code beneath:

Hello [subscriber:firstname | default:there],

 You've received this message because you subscribed to [site:title]. Please confirm your subscription to receive emails from us:  

Any assistance would be greatly appreciated for this template and future MailPoet template formatting ?

best regards
