Windows Mass Email Software Needed

I need a ready-to-use bulk email program that installs on Windows and comfortably pushes out up to 20 000 cold emails every day. Consistent inbox placement is critical, so the solution must sustain at least 70 % deliverability and handle standard cold-outreach needs such as warmed-up SMTP rotation, throttling controls, DKIM/SPF configuration and automatic bounce processing. Full, real-time analytics are a must: I have to see open rates, click-through rates and unsubscribe rates at minimum, along with spam-complaint flags so I can quickly prune lists. Personalisation isn’t required—plain text blasts are fine—but clean list uploading, suppression management and simple template storage will help keep campaigns organised. Because I’m ready to purchase as soon as it proves itself, I’ll need a trial or test licence long enough to push a live batch and confirm deliverability and reporting accuracy. Deliverables (acceptance criteria) • Windows installer or portable executable of the application • Trial credentials or licence key sufficient for one full test campaign • Brief setup guide covering SMTP integration, DNS settings and analytics dashboard • After successful test, link or invoice for the full commercial licence If you already have a mature, battle-tested Windows solution that ticks these boxes, let’s talk so I can start testing right away.
