Your cold email reply rate is 2%. Top operators hit 8-12%. Half the time it's deliverability (you're in spam and don't know it). The other half it's messaging (hitting the inbox but getting deleted in 3 seconds). We fix both. Technical audit + messaging rebuild + 90-day monitoring. Free inbox placement test.
Founders and sales teams in Boston running cold outbound are often hitting 2% reply rates without knowing if the problem is deliverability or messaging. Half the time it's technical — you're landing in spam. The other half it's copy. We audit both, rebuild what's broken, and monitor for 90 days. Boston sales teams using this hit 8–12% reply rates.
You invested in Apollo, Clay, Instantly, or Smartlead. You built sequences. You're sending 2,000 emails a day. Your reply rate is 1.2% and you're not sure if the messaging is wrong or if you're invisible to half the inboxes. Here's what most founders don't realize: Google and Microsoft tightened sender reputation enforcement in 2024, and as of 2026, roughly 30-50% of cold email from improperly-configured domains lands in spam before anyone reads a word. SPF is set up but DKIM is broken. DMARC is missing. Your warm-up was 4 weeks when it needed 8. Your domain age matters now. Your subject lines are triggering spam filters you didn't know existed. Meanwhile, no one is auditing this — agencies sell you sequences, tools sell you volume, and nobody's responsible for whether the email actually reaches the inbox.
30-50% of improperly-configured cold email lands in spam invisibly
Google and Microsoft tightened enforcement in 2024. Missing DMARC, broken DKIM, or insufficient domain warm-up means your best-crafted sequence never reaches half the inboxes. You think the messaging is bad — actually the email never arrived.
Typical cold email reply rates are 1-2% — operators who fix both get 8-12%
The 10x gap between median and top performers isn't luck or better copy. It's the combination of technical deliverability (reaches inbox) + messaging (gets read) + targeting (reaches buyers with actual pain). Most operators fix one and wonder why results barely move.
Bad deliverability burns your ICP list
Every cold email sequence that hits spam degrades sender reputation AND teaches Google/Microsoft that your domain sends spam. Damage compounds. A month of bad deliverability can blacklist a domain for 6+ months — meaning your paid ICP data (Apollo seats, Clay credits, ZoomInfo) becomes worthless until you recover.
A sales rep spends an hour crafting the perfect cold email. Sends it to 500 leads. Two replies. The leads are gone and the guessing starts over.
— Ideabrowser Research, Cold Email Scorer AnalysisA 14-day sprint that fixes both halves of the cold email problem. First week: technical deliverability audit and remediation (SPF, DKIM, DMARC, sender score, warmup, blacklist check, inbox placement testing across Gmail/Outlook/Workspace). Second week: messaging audit — subject lines, opening lines, CTA structure, personalization depth — with rewritten templates tested against inbox placement. Plus 90 days of monitoring so regressions get caught.
Get StartedFull technical deliverability audit
SPF/DKIM/DMARC configuration verification. Sender reputation check (Talos, SenderScore, Postmaster Tools). Blacklist status across major RBLs. Domain age and warm-up analysis. MX records and TLS. Catch-all vs individual mailbox setup. Any one of these broken invisibly kills reply rates.
Inbox placement testing across major providers
We seed your sequences into test accounts across Gmail, Outlook.com, Microsoft 365, Google Workspace, and common mailbox configurations. Real measurement: what % of your emails land in Primary, Promotions, Spam, or Quarantine. Not vendor marketing claims.
Messaging audit: subject, opener, body, CTA
Analysis of your 3 current top-performing sequences against reply rate, plus the 3 lowest. We identify spam-trigger words, generic personalization patterns, weak CTAs, length issues. Rewrite templates using proven structures (problem-first, insight-led, reference-based) matched to your ICP.
A/B testing framework for your sending tool
Setup of proper A/B testing in Instantly, Smartlead, Apollo, or whatever you're using. Most operators don't actually A/B test — they rotate templates randomly. We build the testing structure so you can statistically identify winning variants across subject lines, openers, and CTAs over 4-6 week windows.
90-day deliverability monitoring
Weekly sender reputation reports. Monthly blacklist sweep. Quarterly inbox placement re-test. Most deliverability issues come back after 60-90 days if you don't monitor. You get early warning before reply rates drop.
You send us 3 of your current cold email templates. Within 48 hours we run them through our placement test rig (Gmail, Outlook, Workspace, major providers) and report back: what % lands in inbox vs spam, which providers are blocking you, and top 3 likely causes. Zero obligation.
Deep dive on your sending infrastructure. SPF/DKIM/DMARC verification. Sender reputation across major services. Blacklist check. Warmup analysis. Output: prioritized remediation list with specific DNS changes, tool configuration fixes, and warmup protocol.
We coordinate with your DNS admin (or IT contact, or sending tool support) to implement fixes. Re-test after each major change. By end of week 1: verified configuration, clean blacklist status, confirmed DMARC alignment.
Analysis of your current templates against your actual reply-rate data. Rewrite 3 core templates per sequence using ICP-matched structures. Subject line A/B variants drafted. New templates inbox-placement tested before handoff.
Weekly monitoring dashboard configured. Alerts set for reputation drops. Written playbook for team: how to onboard new sending domains, how to spot deliverability issues early, how to respond to blacklist events. 90-day monitoring begins.

Our methodology is built on proven frameworks
We are NOT a cold email agency. We don't send emails for you, source lists, or run sequences. We fix the infrastructure and messaging so YOUR team (or your existing agency) gets better results from the same effort. Many of our clients run internal SDR teams; others use agencies. Our work complements both — we're the deliverability + messaging layer nobody else owns.
