Hi Saurabh,
Thanks for your response. I did as you requested and even deactivated my caching plugin (I use Litespeed cache). I ensured I purged the cache multiple times too.
After a number of trials, I found out that the setup worked when I stick to just text content. it only cleared when I added emojis. I don’t understand the reason for this but I have removed all emojis in the text content and the email notification is working now.
Thanks!
