Dear Project Provider,
I have read & understood your requirement for a Google Sheet based Script to send emails based on filtered data. I have already developed similar scripts, and certainly develop your requirement.
Moreover, you could send data from your custom domain email, if you wish, and you could get reply to your custom domain email. Additional features shall be with attachments, templated emails (beautifully designed with images). However, sending templated emails shall be slightly costlier.
Hope, we could discuss further!
