Mail Merge Multiple Data to One Email ID

Hi all

For example, I have the details in an excel sheet as seen below -

Unique ID - Comment - Email ID

A - Hello - email1@email.com
A - Hi - email1@email.com
B - What - email2@email.com
B - Hiya - email2@email.com

When we use normal mail merge with excel, from the details above - FOUR emails will be sent, TWO to email1@email.com and TWO to email2@email.com.

What I want to send to the email recipient ( say, to : email1@email.com ) is as below, in ONE single mail -

A - Hello
A - Hi

Please let me know how to carry out the process.

TIA
