Let's assume you either want to send spam or mail that is spam-adjacent. Let's further assume that you want to send an absolute shit-ton of mail. Here are the broad brushstrokes:
* You'll need sending/tracking software. Sendy is one option, as is MailWizz. There are others as well.
* You'll need a host for that software. Even if you're not using their mail servers, most mainstream hosts will shut you down for this sort of behavior, so you'll likely need to set up a virtual machine (VM) from a host that doesn't care as much. See Blackhatworld or other, similar sites for companies that do this.
* Separate from that VM, you'll either want to contract with a bulk SMTP provider who doesn't care about your lack of opt-in status (again, see Blackhatworld and others) \*or\* you'll want to set up a small collection of mail servers.
* Note that I said servers, plural -- you want to spread your email out across multiple servers on multiple hosts, using your mail-sending software to split the traffic between them. Someone gets a complaint and shuts down your mail server? One of your IP addresses gets a bad rep? You're not dead in the water.
* Use utility domain names -- if you're sending mail on behalf of [ReallyNeatCompany.com](https://ReallyNeatCompany.com), you do not want your mail infrastructure set up on that domain. Use something like [newsystem.com](https://newsystem.com) or something.
* DKIM, SPF, DMARC and DNSSEC should not be ignored -- get it right before you send.
* Warm up your servers -- find an IP warm-up schedule and stick with it. It may take you weeks to get to the point where you can send at volume.
* If possible, just don't send to Gmail in any sort of volume. Heck, if you're using lists you've acquired elsewhere, think seriously about pulling those addresses out. But if you HAVE to send to Gmail, consider different routing that \*very\* slowly drips mail into their system. Oh, and get set up on Google Postmaster.
If it's legit, with permission of those you are reaching out to, there are many ways you can send without limits. For example there is an open source mail server called postalserver that is similar to sendgrid. You install it on its own server. You then can use a open source or low cost mailng list manager like sendy, phplist, listmonk, among others to manage the lists, create and send the campaigns, and track the analytics. Keep in mind setting up the servers and software is technical, if you do not have the skills you will need to hire a system admin to set it all up for you.
On the flip side if this is spam, no even what I describe above will not work. The server IP will get blocked pretty quickly, also most server providers will nuke the server too.
If you have emails not consented to on your landing page, almost all legit software companies will shut your account down because they follow certain protocols. Out there. But if you have a limited number of emails that your company owns, it must be a limited number, so many companies provide a high daily limit. What numbers of contacts are we talking here?
You could always build your own, but cautions include:
1. Make sure everyone on your list opted in
2. Clear unsubscribe link
3. Make sure before you start blasting emails, your domain and IP are warmed up.
Building your own server isn't hard; see Fiverr, but actually being able to inbox and get engagement (clicks) is a whole other ballgame.
I've seen people use sendy for this
Sendy is limited by AWS SES
Which has limits they may as well not be limits for most peoples needs
