The problem · day 31

Four weeks of warmup. One bad volume jump.

Domain warmup tools get you to day 30 with a clean reputation. Then the marketing team turns on real volume. By Tuesday, you're in spam. By Friday, the domain is dead.

Reputation looks fine.

FROM THE FOUNDER
I built RampCORE because I kept watching operators warm their domains by the book, hit day 31, push the volume their campaign actually needed, and torch the reputation they just spent four weeks building. The math wasn’t the problem. Nobody had a tool for the math.

90 SECONDS

Or just watch it work.

Quick walkthrough of the dashboard, the schedule engine, and the alert flow when a domain’s reputation dips mid-ramp.

The gap nobody else owns

Email reputation has four phases. Most tools cover one.

Warmup tools handle days 1–28. After that, you're alone. RampCORE owns days 29–60 — the phase where most domains die.

Days 0–28

Warmup

Cold domain. Send to inbox-warming pools. Build sender history. Solved by Instantly, Lemwarm, Warmbox.

Days 29–45

The cliff

Real campaigns begin. Volume jumps 25–50x in a single day. ESP throttles. Spam filters react. RampCORE controls the curve.

Days 46–90

Scaling

Steady volume. Watch for reputation dips, bounce spikes, complaint rate. Throttle alerts if DSI drops. We carry it.

Our job

Day 90+

Steady state

Domain is mature. Volume is predictable. Continued monitoring is light-touch. RampCORE keeps watching every 6 hours.

For the operator who runs email like infrastructure, not like a creative project.

Inside RampCORE

One dashboard. Every domain. Every ramp.

Color-coded health across your entire portfolio. The 30-second daily check that replaces your spreadsheet of doom.

AGENCY MODE

If you run client domains, the math gets uglier.

One inbox burning hits one team. Ten client domains burning hits your retainer. RampCORE was built for the agency seat — every domain on its own ramp, every brand on its own label.

Fully white-labeled. End to end.

Clients log in to a tool that looks entirely like yours. Your brand on the dashboard, your brand on the reports, your brand on every email they get.

Setup is a 20-minute onboarding call. We do not exist to them.

Per-client schedules

Every domain gets its own ramp, its own DSI, its own alert thresholds. No cross-contamination.

Branded client reports

Weekly health reports auto-generate with your branding. Client sees your agency, not us.

Team seats, audit trail

Account managers, strategists, ops — each gets their own login. Every config change logged with who and when.

One bill, all clients

Unlimited domains under a single Agency seat. Stop running domain math in spreadsheets.

A spreadsheet. A warmup tool. Nothing at all.

Three honest alternatives. Here is what each one actually does — and where the gap shows up at scale.

PRICING

Free is real. Pro is the operator tier. Agency is the wedge.

Most pricing pages bury the free plan. We lead with it because one warm domain doesn’t need a card. Scale up when you actually need to.

THE METHOD

No black box. Here’s exactly how DSI is calculated.

We’ve seen too many deliverability tools hand-wave with proprietary scoring. RampCORE shows you the formula. If we’re wrong, you can see where.

peak_volume / esp_safe_limit = ratio
if ratio ≤ 0.50 → 95 − ratio × 10 SAFE
if ratio ≤ 0.85 → 90 − (ratio − 0.50) × 80 CAUTION
if ratio > 0.85 → 62 − (ratio − 0.85) × 80 HIGH RISK
DSIfinal = clamp(5, 99)

Three inputs. One score.

  • peak_volume — the single highest send day in your 30-day ramp window.
  • esp_safe_limit — published daily limit × safety coefficient (0.80–0.90 depending on ESP). Lower coefficient for stricter platforms like Google Workspace.
  • ratio — how close your peak gets to the ESP’s wall. Anything above 1.0 means the schedule will trigger throttles.

DSI updates daily on real send data once you’re live. The pre-launch score from the calculator is a forecast against your stated target, not a guarantee.

QUESTIONS

The ones we get every week.

No. Warmup tools handle days 0–30, sending small test exchanges to build inbox placement. RampCORE handles days 30–90 — the volume ramp after warmup ends. Most senders blow the entire warmup investment on a single day-31 volume jump. We integrate with your existing warmup tool rather than replace it.
Inbox placement rate tells you what already happened — the percentage of your sends that landed in primary inboxes yesterday. DSI is a forward-looking pressure score: how close your planned volume gets to your ESP’s safe limit, factored against current reputation signals. Inbox rate is the autopsy. DSI is the early warning.
12 ESPs are fully modeled with safe-limit math: Google Workspace, Microsoft 365, SendGrid, Mailgun, Postmark, AWS SES, Brevo, Mailchimp, Gmail SMTP, plus three more rolling out this quarter. If your ESP isn’t on the list, you can set a custom daily limit manually and the engine handles the rest.
For Free and Pro, under 5 minutes — connect your ESP via API key, point us at your domain, the schedule generates immediately. For Agency white-label, count on 20–30 minutes on a setup call: we configure the CNAME, upload your brand, and walk you through the first three client domains. Most agencies are live the same day they sign up.
You get an immediate Slack and email alert. If DSI drops below the threshold you set (default 70), RampCORE recalculates your next safe daily volume and gives you the exact numbers to set in your sending platform — Instantly, Smartlead, SendGrid, GoHighLevel, whatever you use. The product monitors and recommends; you control the actual send. The point isn’t that crashes never happen — it’s that you find out in 6 hours instead of 48, with a plan instead of a panic.
Yes. RampCORE doesn’t replace your sending platform — it sits on top of it, telling you how much to send and when. Whether you’re sending through Instantly, Smartlead, Lemlist, or raw SendGrid, the ramp schedule and DSI work the same. You just enforce the daily caps in your platform of choice.
Fair question. Two things: (1) the math is public — see the Method section above. You can sanity-check every recommendation against the published ESP limits. (2) The Free plan exists so you can test the engine on a low-stakes domain before betting a $50K retainer on it. Run it for two weeks. If DSI ever lies to you, cancel and tell us why.
