Here are my suggestions to improve the email below. 

Firstly, I would change the subject line to be more attention-grabbing. I would mention in the subject line that this is a limited offer.

Secondly, it would be better to summarize the promotion in the email body and include a clear call-to-action button with a link to a page with more details. Additionally, including some previous wedding photos would make the email more appealing.

Lastly, I suggest adding the managing director's signature and a footer with links to all their social media platforms, as well as an unsubscribe option, in compliance with regulations.

Overall, I believe that implementing these changes will significantly enhance the effectiveness of the email in achieving its intended purpose."
