We're building the
complete outbound engine.
Most outreach tools stop at “send.” Stynar runs the whole cycle — AI writes and sends personalized sequences, every reply syncs to one inbox, and the AI books the meeting for you. One platform, first email to booked call.
Outbound was half-built.
So we finished it.
We kept running into the same wall with every outreach tool: they were great at sending emails and useless after that. Replies landed in a different app. Hot leads waited in a mailbox no one checked. Booking a call meant a chain of back-and-forth messages.
So we set out to build the part everyone skipped: the full loop, from the first email to the booked meeting. AI writes and sends with real web context, deliverability is handled, replies sync into one inbox, and the AI books the meeting the moment a prospect shows interest.
Stynar is in early access today. We're a small team shipping quickly, working closely with the first teams using it, and building the most complete outbound platform we can — one honest feature at a time.
Outreach tools stop at “send”
Most platforms help you blast emails, then leave you on your own. Replies scatter across mailboxes, hot leads go cold, and meetings slip through the cracks.
Write and deliver, done right
We started with an AI writer that reads real web context, plus a deliverability engine handling SPF, DKIM, DMARC, and domain warm-up — so emails sound human and land in the primary inbox.
Replies and meetings, automated
Then we built the unified replies inbox and AI meeting booking. Every reply syncs to one place, and when a prospect wants to talk, Stynar books the meeting for you.
In early access
Stynar now runs the whole outbound cycle in one platform. We're opening it to early teams and shipping fast based on their feedback.
One platform for the
whole outbound loop.
AI sequences + deliverability
AI writes personalized sequences on your choice of model and lands them in the primary inbox — SPF, DKIM, DMARC, and warm-up handled.
Unified replies inbox
Every reply syncs natively from Gmail and Outlook into one thread-aware inbox, auto-classified so you see what matters first.
AI meeting booking
Stynar detects meeting intent in a reply and books the call on your calendar automatically — no manual scheduling.
Six principles that drive
everything we build.
Deliverability First
If your email doesn't reach the primary inbox, nothing else matters. SPF/DKIM/DMARC validation, automated domain warm-up, and reputation monitoring are built into the platform.
Real Personalization
Generic blasts are dead. Stynar's AI reads each prospect's website, role, and public context to write a genuinely specific opener and body — not just a “Hi {{firstName}}” swap.
The Whole Loop
We don't stop at sending. Replies sync into one inbox and AI books the meeting automatically, so the entire cycle — send, reply, book — runs in a single platform.
Your Model, Your Choice
Run every email on the model you trust. Pick the free GPT-4o mini baseline, or step up to GPT-5.5 and Claude Opus for high-stakes outreach. You only pay the credits each model costs.
Security & Privacy
Connected mailbox tokens are encrypted and secrets are kept in a managed vault. Your leads and credentials are yours — we never sell your data or your lead lists.
Built for Compliance
Designed for CAN-SPAM and GDPR from the start — automatic unsubscribe handling, suppression lists, and data-deletion support are included, so you stay compliant without building it yourself.
A small team,
building in the open.
Stynar is built out of Pune, India by a small, focused team that cares about the details — clean deliverability, copy that actually sounds human, and software that does the boring follow-up work for you.
We work closely with the first teams using Stynar, ship quickly, and would love to hear from you — whether it's a bug, a feature request, or just a hello.
Our mission: turn cold outreach
into real conversations.
The best business relationships start with a relevant, honest first touch — and they should turn into a booked call without the busywork. Stynar exists to make that whole journey effortless, whether you're a solo founder or a growing sales team.
