How to send mail to a group of contacts

Hello there, I'm new to this Zoho Creator thing and I'm learning it.

I have a need to create dynamic communication list using the email of my contacts form application (in Zoho Creator).

Here is the exact sample. I have a contact directory with 1200 contacts. Some of the fields list are, NAME, GROUP, EMAIL.
Lets say that I want to invite the people that belongs to the "ENVIRONMENT GROUP" to a conference.
For that I run a view form with the filter "ENVIRONMENT" in the "GROUP" field and they are 163.

I wood like to pick dose 163 contacts from the view form in one time and sen an specific mail to all them using outlook/gmail.

This is a real sample, I need to build this application or functionality for manage the communications agenda form an foundation institution, and they have a lot of GRUOPS OF CONTACTS to manage different communications.

I would SINCERELY appreciate if anyone knows how to do this with Zoho cerator

MANY THANKS!
