PULSAR Mail Sender

Timed. Precise. Relentless. The desktop bulk email engine with built-in deliverability AI.

PULSAR Mail Sender is a self-hosted Windows desktop bulk email platform built on .NET 10 and a MailKit/MimeKit sending engine, with no per-email cloud fees. It rotates multiple SMTP servers through warm-up, proxy, and rate-limiting logic while an embedded ASP.NET Core tracking server records opens, clicks, and unsubscribes locally. AI-assisted spam scoring (Claude API with a local Ollama fallback), DKIM signing, drip sequences, and A/B testing give you agency-grade deliverability in a one-time-purchase app.

$69 USD, one-time payment, lifetime license.
