Email marketing tools and guides

I have a list of around 150k users of my software from before, and I would like to mass email all of them, though they haven't opted in for email, just signed up for my software.

So if I wanted to do that, how do I do that safely? Is there any tutorial guide and tools you guys can recommend?

I would be grateful for your advice. Thank you.

You can use a plug and play solution to send your emails using multiple Gmail accounts and proxies.

Or build your own SMTP servers, you'll need some syslinux skills and a good understanding of how bulk mailing works.

You can start by sending a newsletter, Asking to optin to claim some discount one user optin. you can start sending emails.
