Easiest way to inbox about 1k emails?

What would be the easiest way to go about this? non opt in ones.

You may use mailchimp and you can send 1k emails for free

Yes, mailchimp for non optin, what a fucking great idea.

OP, 1k emails isnt much, you could probably inbox via a couple of gmail accounts

If you need help with understanding how to do appropriate email marketing, PM me... most folks have no clue what they are doing and thus get shut down quickly by ISPs blocking their IP addresses. It is not rocket science but most people just are too impatient to learn how to do it right the first time.

PM me if you need help and are coach-able.
