We built the features that actually move the needle on deliverability, stripped out the bloat, and priced it fairly. Here's exactly what you get.
Every feature below solves a real problem our users had with other platforms.
Multi-layer DNS + MX + SMTP probe verification runs in parallel batches. Verify 10,000 emails in under 10 minutes — not hours. Disposable and role-based addresses are caught automatically.
Pause, resume, or cancel a campaign mid-send without losing progress. Real-time counters for delivered, failed, and pending — visible the moment you press send.
Connect Gmail, SendGrid, Mailgun, SMTP2GO, Postmark, or any custom SMTP server. Rotate between senders per campaign for maximum inbox placement.
Automatically extracts first name, last name, or full name from your CSV columns and the Name <email> paste format. Every {{Name}} tag resolves to a real person.
Every verification run is saved with its label, stats, and full results. Re-download as CSV, load directly into a campaign, or delete when no longer needed.
Design once, reuse everywhere. Your HTML templates are stored server-side, previewed live, and available in one click during campaign creation — with no copy-paste.

Campaigns run through a BullMQ + Redis queue. Your campaign keeps sending even if you close the browser — no frontend dependency.
All campaign stats, contact history, templates, and verification results are stored in PostgreSQL — durable, queryable, and backed up.
Your SMTP passwords are AES-256 encrypted before hitting the database. They're never logged or exposed via API responses.
JWT authentication on every protected route. Per-IP and per-user rate limiting prevents abuse — your credits are protected.
The Python verifier uses asyncio to probe up to 20 SMTP connections concurrently per batch, with configurable concurrency limits.
Transparent pixel and link-wrapping tracking with campaign-level aggregation. Opt campaigns in or out per send.
Pay for what you send. No seat fees, no feature tiers, no surprises.
