Harvesting emails with mac

[PBSGCREC]

For MAC, does anyone know of any software or online tool to harvest emails from Google?

I used 'Email Grabber' years ago, but it's been a while.

Thanks.

And what would you do with those emails?
AFIK, Google does not even cache emails.

I want to ask them if they would like to receive a free digital copy of my magazine.

I am aware of all the above and I have done on a regular basis, however, I would still like to build a list of unknowns and ask them once (opt-in). I am not going to SPAM them.

That is the wrong way to do that: unsolicited email =spam

1. You need to pay to acquire a mail list with proof of an opt-in and that can be hazardous; or,
   
2. Build you own list from your own website opt-ins; or,
3. Collect email subscriptions from either squeeze pages or content locked documents.

Unless the emails are from a source like the above you will not find any commercial email SMTP (in North America or Europe) that will send them out for you anyway.
