Evaluating to use non-optin email list

I'm evaluating to use non-optin email lists (1M+) scraped on Instagram for my business.
I use wix for email marketing and I can send up to 1M emails per month.
For the experienced ones, how do you suggest to proceed in order to be as safe as possible?

I'm trying to clean the emails by scraping only real IG users (using strictly parameters) and I'm also trying to not send emails twice to the same account with multiple campaigns (in order to avoid spamming behavior and to be annoying).

I'll send just a single email to present my business and then try to do remarketing (limited time deals) only on the one who clicked to visit the website.

I did a test with 5k emails and I got 30% open rate, 5%click rate, 6,7% bounce rate and I got 2 new clients.

I'm looking for advice by experienced email marketers in order to avoid to make dumb mistakes like slip into some spam traps.

wix allow you to send 1M email within a month? Just curious.

Meanwhile, do you optimize your sfp, dkim, dmarc as well as your content to avoid fall into spam box?

Yes, it does with a 50$ monthly fee.
About sfp etc.. It's all automated on wix, I just use templates and I compile them. With mail-tester.com I got a 7.1/10 with 2 errors:

-2.503 http://wiki.apache.org/spamassassin/Rules/FREEMAIL_FORGED_REPLYTO Freemail in Reply-To, but not From (this is because I don't have a [email protected] as reply-to email?)
-0.5 because of 10 images with no alt attribute.

I'm ignorant of technicalities and I don't know any of these errors and I don't know sfp dkim dmarc (I'll google it and study them but for now 0). Is that 7.1/10 good?
Man I'm just using a user-friendly tool that wix is giving to me
