Three send modes. One desktop.
Built-in MTA, custom SMTP rotation, your own Ubuntu nodes, and Microsoft 365 mailboxes — all driven from a single Windows desktop. Pay once, own the app forever. You bring the infrastructure.
Three engines. You pick.
Different campaigns deserve different infrastructure. AlphaXSender lets you switch the engine per campaign without leaving the Compose tab.
Built-in MTA
Direct-to-MX delivery on port 25 from your machine. Useful when port 25 is open and you want a zero-dependency send.
Custom SMTP rotation
Pool your own SMTP servers and route across them with round-robin, weighted, LRU, or random rotation. Built-in proxy support per account.
Your own nodes
Provision external Ubuntu MTAs that you own, over SSH, right from the desktop. Postfix + OpenDKIM + Redis + Postgres, installed and online in one pass.
Built for the way you actually work.
Day shift. Night shift. Hot desk. Home office. The dashboard reads the same — KPIs across the top, scheduled sends on the left, live activity in the middle, system health on the right. No mode switching, no context loss when you walk away from your machine and come back.
-
Always-on heartbeatA glance tells you: license, port 25 reach, tracker health, proxy status, node count.
-
Pause and resume in flightActive campaigns expose pause/resume right on the tile — no need to drill in.
-
Light + dark, first-classBoth themes are designed; the light one is not an afterthought.
Every workspace, designed.
Compose campaigns, enrich leads with AI, sort and dedupe lists, and send through your own Microsoft 365 mailboxes — each module gets the same care as the dashboard.
Campaign Builder
Recipient list, subject, sender, HTML editor with live preview. Pick a send mode and fire.
Leads Enricher
Drop a list of websites and let the on-device LLM pull contact details, industry tags, and qualifying notes.
Email Verifier
Validate every address before you send. NeverBounce, Debounce.io, or MillionVerifier — your key, normalised verdicts.
List Sorter
Dedupe, normalise, validate. Splits clean from dirty so what enters the campaign is what you intended.
Office B2B
Send through your own Microsoft 365 / Outlook mailboxes via Microsoft Graph — device-code OAuth or token import.
Three steps. That's it.
No SMTP wrangling. No deliverability hacking. Just a desktop app and the engine you choose.
Open
Launch the desktop app. Paste your license. You're online.
Input
Drop a recipient list, write a subject, paste your HTML. Live preview while you type.
Send
Pick a send mode and fire. Live progress streams back to the dashboard with per-recipient logs and pause / resume controls.
Pay once. Own forever.
