Reliable Bulk Email Platform Setup

I’m ready to start pushing regular promotional offers to an existing subscriber list and need a dependable bulk-sending platform that can maximise deliverability and directly drive sales. I already have the contacts cleaned and permission-based, so the main focus is choosing or configuring a service that scales, avoids spam traps, and provides clear analytics.

Here’s what I’d like to walk away with:
• A platform (or self-hosted solution) fully set up under my domain, warmed IP or shared pool explained, SPF/DKIM/DMARC correctly aligned.
• My list migrated, segmented for promotional blasts, and a basic responsive template loaded.
• A short walkthrough on scheduling, A/B testing, and reading the conversion metrics so I can launch future campaigns solo.

Any well-known SaaS (Mailchimp, SendGrid, Brevo, etc.) or a VPS-based option is fine as long as you can prove reliable inbox placement. Let me know your preferred stack, timeline, and examples of past high-volume campaigns you’ve handled.
