Not delivering all mails and losing formatting using mail merge

Hi friends,

Greetings from me!

I want to send wishing mails using mail merge.
The mails are not delivering from top to bottom that is from first entry to last entry.
I’m not getting a name of person having a birthday after a word ‘Dear ,’
I’m losing the formatting of mails as formatted in a main word document.
The picture of cake is aligning left in mails which should be centered as in main word document.
I want a current date (today) under the picture cake leaving one blank line above and under a current date in green color.

Any help will be highly appreciated.

Thanking you in anticipation.
