Everything you need to ship better emails
Each tool is built for a single, sharp job. No bloat. No "AI suite".
3 angles, every time. Pick the one that fits.
You get a direct take, a story-led take, and a contrarian take — each tailored to your audience and brand voice, with one-line rationale per change. Skip the blank page and the second-guessing.
- Streams the first variant in under 2 seconds
- Variant rationale so you know why each line changed
- Drop into your ESP, or use our editor
Your reps lose ~4 hrs/week to follow-up writing. We auto-draft from CRM activity. Worth a 15-min look?
A VP of Sales told me last week his 40 reps each lose half a day to copy-paste. That's one full headcount of follow-up writing.
Most 'sales automation' fails because it sends. The prospect can tell. We draft — your reps still send.
Subject lines, scored before they ship.
Get 8 candidates with a predicted open-rate and explicit risk flags — spam triggers, length, audience fit. We surface the why so your team learns, not just the what.
- Predicted open-rate score 1–100, explained
- Risk flags catch spam-trigger words and ALL-CAPS
- Pair with the preheader generator for synergy scoring
Catch deliverability problems before send.
Every draft gets local lint instantly — spam words, all-caps ratio, suspicious links — plus a deeper AI pass that flags weak CTAs, buried ledes, and AI-tells in your copy.
- Instant local checks: no AI cost, no waiting
- Per-line annotations point to the exact span to fix
- AI-likeness sub-score — sounds human, not GPT
Trusted by operators who care about open rates
Real customer quotes shown below are illustrative pre-launch placeholders.
"Rewrote our entire welcome series in an afternoon. Open rates climbed from 38% to 51% in the first month."
"The score-then-rewrite loop is what I always wanted from a copy tool. It actually catches the lazy patterns I write into every cold email."
"Deliverability lint caught three things our old ESP didn't. We were getting flagged by Spamhaus and didn't know why until this told us in 2 seconds."

FAQ
Do you send my emails?
No. We are intentionally not an ESP. We optimize your copy; you keep sending where you already send (Mailchimp, HubSpot, Resend, your CRM, anywhere).
How does scoring work?
Hybrid: instant local lints (spam words, readability, link audit) plus a Haiku pass for clarity, CTA strength, and persuasion structure. Composite is weighted by email kind.
Will my drafts train your model?
No. We never train on customer content. Drafts live in your workspace until you delete them.
How accurate is the open-rate prediction?
It's a calibrated rubric, not an ML model trained on engagement data. We label it ‘predicted’ for that reason. Good for relative comparison, not absolute promises.
Can I self-host?
The product is built on Dokploy-friendly containers (external Postgres, Redis, MinIO). Enterprise self-host is on the roadmap.
