Deliverability autopilot
We read real bounces and spam complaints every few minutes, score each sender, and throttle or pause automatically before you burn a domain.
Around half of all email “opens” are faked by Apple Mail and bots. Norbelys filters them out — so you optimize on real replies, and your sending domain stays protected from the first email.

Send from the mailboxes you already use
Apple Mail Privacy Protection silently pre-fetches your tracking pixel. Gmail proxies every image. Security scanners click every link. Most platforms count all of it as “engagement” — and inflate your open rate by double digits.
Norbelys classifies every open and click in real time and shows you only the humans. The numbers you optimize against are numbers you can trust.
Counts Apple MPP pre-fetches, image proxies and bots as real opens.
No deliverability degree required. Norbelys handles the parts that usually take weeks to learn.
Link Google, Microsoft or any SMTP/IMAP inbox in a couple of clicks. We auto-derive your sending domain and walk you through SPF, DKIM and DMARC.
Always-on warmup builds reputation gradually while Norbelys watches bounces and complaints, throttling or pausing automatically before anything goes wrong.
Launch sequences that send in each recipient's timezone. Watch real replies land in one inbox — with bot and Apple MPP opens filtered out of every report.
Warmup, sending, deliverability and replies — built to work together, so you ship campaigns instead of babysitting them.
We read real bounces and spam complaints every few minutes, score each sender, and throttle or pause automatically before you burn a domain.
Unlimited warmup on every plan, ramped gradually on a separate budget — so warming a mailbox never eats into your sending limit.
Per-recipient timezone delivery with sending windows and human-like jitter. Daylight saving handled for you, no spreadsheets.
Run variants on any step. Once enough real replies land, Norbelys promotes the winner automatically — no dashboard to babysit.
Replies are threaded, classified as human, auto-reply or bounce, and a real reply instantly stops the sequence so you never double-send.
One-click unsubscribe (RFC 8058), automatic suppression and encrypted credentials — the parts that keep you safe, on from day one.
The dashboard is just a client of the same public API you get. Send your first email in minutes, automate the rest, and never hit a feature that's “UI only.”
import { Norbelys } from "@norbelys/sdk";
const norbelys = new Norbelys(process.env.NORBELYS_API_KEY);
// Launch into a cold sequence — one endpoint.
await norbelys.messages.send({
from: "sara@acme.com",
to: "founder@startup.com",
subject: "Quick question, {{first_name}}",
send_mode: "sequence",
sequence: "seq_q3_founders",
});
// → { id: "msg_8f2c…", status: "queued" } Whether you're sending your first cold email or your millionth, Norbelys meets you where you are.
Skip the agency retainer. Connect a mailbox, let warmup run, and start booking meetings with sequences that protect your domain from day one.
Run multi-step sequences at scale, let A/B tests promote their own winners, and trust the numbers because bots and proxies are filtered out.
Separate workspaces, unlimited mailboxes and flat pricing that doesn't punish you for growing. Report numbers your clients can actually believe.
Drive cold campaigns and bulk sends from one API. Wire opens, clicks and replies into your own product with webhooks and a typed SDK.

“We're a new company, so you won't find a wall of logos here — we haven't earned them yet. What you'll find is a product built on one rule: tell you the truth, even when the truth is a lower open rate. We'd rather show you 41% real opens than 64% of fiction.”
No contracts, no lock-in, no “talk to sales” to leave. Pay monthly and stop whenever you like.
Coming from Smartlead, Instantly or Lemlist? We'll personally help move your campaigns, mailboxes and suppression lists.

Deliverability is the whole point. Every mailbox gets always-on warmup, we monitor real bounces and spam complaints every few minutes, and we automatically throttle or pause a sender before its reputation slips. You bring a healthy domain and relevant copy — Norbelys runs the protective machinery.
Included on every plan, with no limits and no separate fee. Warmup runs on its own budget, so warming a mailbox never eats into your campaign sending limit.
Because they're real. Apple Mail Privacy Protection and bots auto-trigger your tracking pixel, which inflates open rates across most tools. Norbelys filters those out and shows only human opens — so the lower number is the honest one. We optimize on replies, which can't be faked.
Connect Google or Microsoft, or any mailbox over SMTP/IMAP, in a couple of clicks. We auto-derive your sending domain and guide you through verification.
We walk you through SPF, DKIM and DMARC and verify they're configured correctly, so you meet the Gmail, Yahoo and Microsoft sender requirements that now gate the inbox.
A free tier invites spammers onto the shared warmup pool, which drags inbox placement down for everyone. Paying upfront keeps the network clean and your emails landing. Plans start at $29/mo and you can cancel anytime.
Yes — and we'll help. Reach out and we'll personally move your campaigns, mailboxes and suppression lists so you don't lose momentum.
Credentials are encrypted and every account's data is isolated. We honor RFC 8058 one-click unsubscribe, are GDPR-ready, and let you export everything on demand.
Anytime. Plans are month-to-month with no contracts and no lock-in, and you can export your data whenever you like.
A first-class one. Cold campaigns and bulk sends go through a single POST /v1/messages endpoint, with webhooks, a typed SDK and full reference docs. The dashboard is just a client of the same public API.
Connect a mailbox, let warmup run, and watch real replies land — with your domain protected from the very first send.
