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
