Proper Way to Send a "light" Bullk Email amount

Hey guys so I am looking to start sending bulk emails and avoid having my current IP Address blacklisted...

Currently I have my own tools that work in two ways: One sends emails through smtp with a 100 email per day cap, and another version that auto inputs the data through a chrome extension as if a user is on the computer, with a time-limit in between each email of about 30 seconds but that also caps at about 3-400 emails.I figured I can buy some proxies and create a new email address per proxy so lets say 10 email accounts (using gmail) with 10 proxies, sending about a 100 per proxy - 1000 emails total per day...

Any thoughts on the method above, I have yet to purchase proxies ($2-3 per each monthly as it looks like the going rate for private proxies), or is it better to use a different service or another method? I am a programmer so have experience automating everything it is the part of avoiding my IP being blocked and be able to send a lot more emails without becoming spam... Also, not too experienced with proxies so might need help with that...

The emails I send I plan on being able to reply to each email that I receive to those accounts, with the accounts looking real, as I will use different little tweaks on a username. Also, want to send anywhere from 1,000-10,000 emails per day if possible.

There are services out there that allow you to simply import an email list (getresponse.com still does, I think) and send to unverified recipients. However, if a whole bunch of them complain spam, you risk getting your account closed.

So in that case, send an email with a landing page and then try to get the most % opt-ins. Then target that new email list. Benefit of that is it allows you to have a targeted audience.

Those type of websites cost a lot more money, trying to keep it somewhat cheap, under ($50)
