How it works

From a raw lead list to a real conversation.

Setup

Connect inboxes

Link Gmail, Microsoft 365 (OAuth), or any SMTP/IMAP mailbox. ReplyNorth verifies DNS — SPF, DKIM, DMARC — before a single email goes out.

The platform

Everything an outreach engine needs — nothing it doesn't.

Multi-provider inboxes

Gmail, Microsoft 365 (OAuth) and generic SMTP/IMAP — managed in one place.

AI from your Knowledge Base

Sequences written from a per-user knowledge base with full version history.

Deliverability guardrails

DNS health, per-inbox warm-up ramps, bounce monitoring and auto-pause.

Smart scheduling

Send windows, timezones, per-day limits and round-robin inbox rotation.

Real-time reply detection

Replies stop the sequence instantly; auto-replies are ignored.

Unified reply inbox

Read and respond to every prospect reply from one dedicated view.

Suppression & compliance

Unsubscribe handling and a suppression list so you never re-contact opt-outs.

Circuit breakers

Per-inbox protection automatically pauses any mailbox showing trouble.

The dashboard

One screen for what went out and what came back

Sends, replies, review queue and bounce rate — the four numbers that decide whether today was worth it.

Global deliverability

Land in inboxes, wherever your prospects are.

ReplyNorth sends on a human-like schedule tuned to each recipient's timezone, rotating across your real mailboxes so volume stays natural and reputation stays intact — anywhere on the map.

  • Timezone-aware sending
    Each lead's send window follows their local working hours, not yours.
  • Round-robin inboxes
    Volume spreads across your real mailboxes so no single one spikes.
  • Reputation guardrails
    DNS checked per domain, warm-up ramps on new inboxes, auto-pause on bounces.

Stop-on-reply

The follow-ups stop the second they reply.

Every sequence watches for a genuine reply. When one lands, remaining steps are cancelled instantly — no awkward “just following up” after someone already said yes. Out-of-office bounces are ignored.

    Hi Priya — noticed Halden just opened a second RevOps role. We help teams like yours start conversations without burning the domain…

    Circling back — happy to share how teams cut manual follow-ups to zero. Worth a quick look?

    Interesting — can you send some times for a quick call next week?

Deliverability-first

Built to protect your reputation at every step.

Send too fast, or to bad addresses, and your domain gets blacklisted. ReplyNorth ramps volume, verifies addresses, and watches health so you stay out of spam.

  • DNS health checks
    SPF, DKIM and DMARC verified before sending.
  • Warm-up ramp
    Volume increases gradually per inbox to build trust.
  • Bounce monitoring
    Rising bounces trigger an automatic pause.
  • Circuit breakers
    Any mailbox showing trouble is protected instantly.
