Removing "Author" in Subscribe-by-Email Plugin

I have the following code but it's not working. I need to remove the author who posted the article when it sends out emails from post.php

<div style="display:none !important; <?php echo sbe_show_featured_image() ? 'float:right;' : 'float:none;'; ?>">
	<?php printf( __( 'by %s on %s', INCSUB_SBE_LANG_DOMAIN ), get_the_author(), get_the_date( $date_format ) ); ?>
</div>

The "display: none !important" should do it I thought, but it's still adding my name to the emails that go out.

Thanks,
David
