SMTP Relay Credentials with VPS and Domain Configuration

I’m preparing a cold-outreach campaign to new prospects and need an SMTP relay configured using my VPS, domain, and Supermailer platform. The goal is to send 5,000 – 10,000 emails daily, ensuring strong inbox placement without delivery or throttling issues...
