Why most cold email campaigns fail

Cold email is no longer about sending as many messages as possible. It is about deliverability, infrastructure, and technical reputation. Most campaigns fail because they are built on shaky foundations that land straight in the spam folder.

We handle everything from domain setup and DNS configuration to warmup and daily deliverability monitoring, so your messages always land in the inbox.

Structured Warmup

We run your domains through a 4-week warmup process to build a healthy sender reputation before sending starts.

Sequence Architecture

We build multi-step sequences using AI personalisation and A/B testing to maximise your reply rates.

04

Continuous Optimisation

We monitor deliverability daily, swapping domains and tweaking copy to keep your inbox rates above 95%.

Frequently asked questions

How many domains and inboxes do we need?

For most clients we set up 3–5 sending domains with 2–3 inboxes per domain. This keeps volume per inbox low, protects deliverability, and means if one domain ever takes a hit, your entire outbound does not go down. We handle all domain purchasing, DNS configuration, and inbox setup.

How long does domain warmup take?

Typically 3–4 weeks. We run a structured warmup using real engagement signals so the domains build a healthy sender reputation before any cold outreach starts. Skipping or rushing warmup is the number one reason cold email campaigns fail from day one.

What sending tools do you use?

We primarily work with Instantly and Smartlead depending on the client's volume and use case. Both are purpose-built for cold email infrastructure and have strong deliverability track records. We configure, manage, and monitor everything inside these platforms on your behalf.

What open and reply rates should we expect?

With a well-built ICP, strong copy, and healthy infrastructure, we consistently see open rates between 40–55% and reply rates between 3–8%. Our average across active accounts sits at 38% reply rate. Results vary by industry and offer but these are realistic benchmarks we hold ourselves to.

What happens if deliverability drops?

We monitor deliverability daily across all client accounts. If inbox rates drop or spam rates rise, we pause sending immediately, diagnose the issue, and fix it before resuming. You will never find out about a deliverability problem from your own inbox. We catch it before it affects results.
