email post notification does not fit in viewing area

Since the change in WordPress, my email post notifications no longer fit in the viewing window of the email message. You cannot see the righthand-side of the article. The white part in the middle which shows the text is too small. There’s too much empty “brown” area.

What can I do to make the viewing area of the email post notification show the whole article from left to righthand-side?

Thanks,
Ruby
