The Problem

Great outreach still lands in spam.

Email providers reward trusted senders. Without warmup and monitoring, your domain never earns that trust — and your pipeline pays for it.

New domains look suspicious

Fresh domains and mailboxes have no sending history. Providers treat them as risky — so cold outreach starts in spam before prospects ever see it.

Spam folders kill pipeline

Even great copy fails if it never reaches the primary inbox. Missed opens mean missed meetings, slower sales cycles, and wasted SDR time.

Reputation drops silently

Blacklists, DNS misconfigs, and sudden volume spikes can tank deliverability overnight — usually without a clear warning until replies dry up.

Powerful Core Features

Everything you need for high-volume growth.

Built for those who can't afford to be in the spam folder. AI-driven precision for modern sales teams.

Human-like AI conversations that graduate your inboxes from zero to high-volume safely.

Automated DNS Checks

Live verification of SPF, DKIM, and DMARC settings with one-click repair guides.

Advanced Analytics

Deep dive into reply rates, open rates, and conversion trends per sender.

Our Protocol

From connect to primary inbox.

Three steps: connect mailboxes securely, let AI warmup build trust, then scale outreach with confidence.

1

Connect Inboxes

OAuth integration for Google Workspace & Microsoft Outlook, or SMTP/IMAP for everything else.

2

AI Warmup & Monitoring

Our proprietary AI starts sending human-like conversations and monitoring domain reputation.

3

Scale Outreach Safely

Consistent primary inbox placement allows you to scale volume without fear of being blocked.

How Warmup Works

Reputation is earned over weeks — not overnight.

Senderup automates the slow, careful process of teaching Gmail and Outlook that your mailbox is a real, trustworthy sender.

Week 1

Gentle ramp

Senderup starts with a few human-like conversations per day — short replies, natural timing — so providers see real engagement, not a blast.

Week 2

Volume grows safely

Daily send volume increases gradually while we watch placement signals. If something looks off, ramp slows automatically instead of risking a spike.

Week 3+

Reputation compounds

Consistent positive engagement builds sender trust. You unlock higher volume with stronger primary-inbox rates across Gmail and Outlook.

What runs every day

Behind the scenes while you focus on outreach.

Send & reply loops

Warmup traffic looks like real people talking — not random gibberish — which is what modern spam filters actually reward.

Placement checks

We track whether mail lands in primary, promotions, or spam so you know reputation is improving before you scale outreach.

DNS & blacklist watch

SPF, DKIM, DMARC, and blacklist status stay under watch so a config slip does not quietly undo weeks of warmup.
