How to Avoid Getting Banned/Blocked Using Mass DM?

I'm planning to set up a few of fresh account, warm it up a few days, then do mass dm to spread a landing page of my website at the speed of 100~50dms/day.
(Sending DMs to people that follow me and people that don't.)

But my partner tells me this isn't going to be effective, my account can be blocked very very quickly, and my DMs will go into their "message request page" which is like the "spam" folder of DMs.

Is there any way to enhance the deliverability of DMs?

follow unfollow then dm users who follow you that way it will be in their actual inbox rather than requests

Thanks, any way to bypass that to users that aren't following us?

If you're doing it manually, don't send the same message over and over, of course

Don't use the same domain on multiple accounts. Set 1 domain / 1 account. Also, remove this part

You will get flagged fast for that.

Thanks, I guess there's really no way to DMs people that doesn't follow, btw do you think it's going to work if I type the domain as text like example[dot]com something to people?

Because the link is to my store, not some spammy CPA affiliate links.
