How Calibrate works

From cold contact
to booked call. In five steps.

Every email we send moves through the same pipeline. No shortcuts, no templates, no batch-and-blast. Here's exactly what happens between receiving a prospect's name and that prospect replying.

Step 01 · Sourcing

The list is half the email.

Most cold campaigns die at the list. Pull names from a single tool, hit send, watch your sender reputation collapse. We don't do that.

Every campaign starts with a multi-source list build. Apollo for firmographics. Clay for trigger events. LinkedIn Sales Navigator for behavioral signal. SEC filings for funding stage. Crunchbase for capital. Job boards for hiring velocity.

Every contact passes through waterfall verification across MillionVerifier, Omniverifier, and ZeroBounce before we accept them into the queue.

Step 02 · Research

We read the way your best SDR wishes they could.

For each contact, we pull a research bundle in under 30 seconds. LinkedIn profile, recent posts, recent company news, latest funding event, hiring patterns, tech stack from BuiltWith, podcast appearances, conference talks. The kind of context your SDR would dig for if they had four hours per email instead of four minutes.

This isn't enrichment. It's understanding. We don't just pull "Series A · $12M" · we understand which investor, what use of funds, and which hiring pattern indicates the prospect is actively trying to grow.

No templates. Ever.

This is the heart of the model. Every other agency has 4-6 templates with merge tags. We have zero templates. We write every email from scratch using the prospect's specific profile.

Same prospect, same ICP, different week → different email. Different prospect, same ICP → completely different angle. The opening line, the trigger reference, the value frame, the CTA · all custom, every time.

And she varies sentence structure across the campaign so spam filters never pattern-match. Three thousand emails per campaign, three thousand distinct writing patterns.

  • 0 templates · 0 merge tags · 100% custom
  • Linguistic diversity scored on every send
  • 40-60 words · plain text · no links · no images

that TechCrunch piece

Hey Maya, caught the TechCrunch feature · congrats. The line about scaling outbound without burning trust is the exact problem we solve.

Couple of B2B SaaS founders we work with hit the same wall right after Series A · we've gotten them to 3-4% reply rates at 5K sends a day.

Worth a quick chat to see if it's a fit?

Human review. Then infrastructure.

We draft. A human reviews. Then it ships through infrastructure most teams will never build.

Our review queue catches the rare bad take · the joke that fell flat, the trigger event that's not as fresh as expected, the company that's actually closer to your competitor than your ICP. Our hit rate is 96%+ on first draft. Our humans handle the rest.

Then it goes out. 20+ branded domains. 1,000+ warmed mailboxes. Google and Outlook only · never cheap SMTP. SPF, DKIM, DMARC dialed in. Inbox placement monitored hourly. Reputation defended 24/7.

Step 05 · Reply

Replies. Triaged. Routed.

The reply is the conversion. Most agencies forward you everything · positive, negative, OOO, unsubscribe, all in one Slack channel · and call it "leads." We don't do that.

We triage every reply within minutes. Positive goes straight to your calendar with full prospect context attached. Neutral gets a custom follow-up. OOO and unsubscribe get auto-handled · removed from sequence, marked in CRM, never bothered again.

Your inbox sees only the conversations worth having.

  • 12-min avg first-response time
  • 4 reply categories auto-triaged
  • Positive replies routed direct to your calendar

That's how it works.
Now watch us run it.

Book a 30-minute call. We'll run our process against your real ICP, show you the dashboard, walk you through a campaign you'd run. No slide deck.
