Ok, I have a question. How do I send personalize bulk email for free (not some free trial software)? Each personalized email needs to be individually sent (so as not to appear as spam). I want to use spreadsheets to pull in the email addresses, first names, etc. I thought Moz Thunderbird with mail merge would do it, but doesn't. Mailchimp doesn't want spam sent. I prefer not to use BCC because of spam blockers.

What do I do? How do I start? Thanks
