So I found some free bulk gmail extractors that work, but they all charge for the full versions.
With Zapier, it appears as though you can only use "received" mails as a trigger for Gmail-- this prevents me from copying existing information from emails in my inbox, because I can't trigger a "new" or "received" email from an email that I already have.
So, I'm left with a programming conundrum: I have all the tools I need, Knack, Zapier, Gmail...
there are even free scripts that exist.
I'm a bit lost on how I can hack this together:
1)copy any email address from any field from all existing inbox emails
2)input into spreadsheet
??? ideas?
I will post my solution later when I figure it out.
