logo takes line-height:150% at top of newsletter

The header with logo is much to height I discover in a test.
The logo = website_263x72.png means 72px height.
But in the code I see a declaration of line-height: 150%;
The size of white space below the logo is so big that customers should scroll below to see the text.

Where can I change the height of the h1 style so the logo takes less space then now.

<h1 style="
	color: #5b5b5b;
	margin:0;
	padding: 28px 24px;
	display:block;
	font-family:Arial;
	font-size: 27px;
	font-weight:bold;
	text-align:center;
	line-height: 150%;
" id="logo">
		                                            <a style="
	color: #5b5b5b;
	text-decoration: none;
" href="https://www.website.com" title="website.com"><img style="max-width:100%;" src="https://www.website.com/wp-content/uploads/website_263x72.png" alt="Sales Partners">		                                            </a>
	                                            </h1>
