- Email Marketing Services
Email that gets read, replied to, and drives revenue.
Most B2B email gets ignored or flagged as spam. We build email programmes that land in the primary inbox, speak to the right buyer at the right stage, and convert attention into pipeline.

- The Problem
Why most B2B email
never converts.
Companies spend hours on email campaigns and get near-zero results. The problem is not the channel. It is how they are using it.
01
Sending to everyone, speaking to no one.
Mass sends to unverified lists with generic copy kill deliverability and response rates. Buyers can tell within two sentences that an email was not written for them.
02
No sequence strategy, just single shots.
One email is not a programme. Without a deliberate multi-touch sequence that maps to the buyer journey, most revenue stays invisible in your database.
03
Tracking opens instead of pipeline.
Open rate is a vanity metric. If your email reporting stops at opens and clicks, you have no idea whether email is actually generating revenue for your business.
- What We Do
Every type of B2B email,
done right.
From cold outbound to lifecycle nurture, we cover the full email stack — strategy, copy, automation, and reporting — on HubSpot and Apollo.io.
- Our Process
From zero to a running email engine.
Four phases. Fully managed. No templates from a generic playbook.
Phase 01 — Weeks 1–2
Audit and Strategy
We audit your existing email setup, deliverability health, list quality, and past campaign performance. Then we build a channel strategy: which email types to run, in which order, for which segments, and what success looks like in 30, 60, and 90 days.
Phase 02 — Weeks 3–4
List Building and Segmentation
We build or clean your prospecting lists in Apollo.io, segment your existing database by ICP, buying stage, and engagement level, and set up the technical foundations — domain warm-up, SPF/DKIM/DMARC, and sending infrastructure — before a single email goes out.
Phase 03 — Ongoing
Write, Automate and Launch
Our strategists write every sequence, subject line, and CTA. Nothing is templated. Sequences are built in HubSpot or Apollo.io with branching logic, reply detection, and automatic suppression. We review, test, and approve before launch.
Phase 04 — Monthly
Optimise, Report and Scale
Every month we review open rates, reply rates, click-to-conversion, unsubscribe trends, and pipeline influenced. We test new subject lines, update sequences based on what converts, and scale what is working. You get a clear report that ties email to revenue, not just engagement.
- Why Choose Qoulomb
Email marketing services that answer to your CRO, not your open rate.
We have spent six years running B2B email for funded startups and enterprise teams. Every engagement starts with your pipeline numbers and works backwards from there.
- Strategy before a single send
We map your ICP and buying stages before touching a subject line. Every email has a defined role in the sequence and a reason to exist.
- Copy written for your buyer, not a generic inbox
Every sequence is written from scratch. Our writers specialise in B2B, they know how technical buyers read, what procurement teams need, and where deals stall.
- Deliverability included, not upsold
Domain warm-up, SPF, DKIM, DMARC, handled as standard. Your emails reach inboxes before we worry about what’s inside them.
- Cold and warm in one programme
Outbound and nurture run in parallel on HubSpot and Apollo.io. One team, one strategy, no coverage gaps.
- Reports tied to revenue, not clicks
You get monthly attribution showing which emails influenced pipeline and closed deals, not a spreadsheet of open rates.
- Client Results
Email that opens doors
and closes deals.
51%
Average open rate on nurture sequences
We were sitting on a 4,000-person list that was completely cold. Qoulomb rebuilt our sequences from scratch and within 60 days we had qualified calls booked directly from email.

Increase in reply rate on cold outbound
Our previous cold email hit under 8% open rates. Qoulomb overhauled the copy, rebuilt our Apollo sequences, and we are now consistently above 40% with replies that actually convert to meetings.

Questions about
email marketing services.
We’d rather answer these before a call than waste 30 minutes on both sides going in blind.
What are email marketing services for B2B companies?
B2B email marketing services cover the full range of email programmes used to generate, nurture, and convert business buyers. This includes cold outbound sequences for lead generation, drip nurture campaigns for pipeline, newsletters for brand and retention, ABM campaigns targeting specific accounts, and lifecycle emails that reduce churn and grow revenue per customer.
What open rate can I expect from B2B email marketing?
Industry average open rates for B2B email sit around 20 to 25 percent. Qoulomb clients average 42 percent or higher across campaigns. We achieve this through tight list segmentation, subject lines written and tested specifically for your audience, sender reputation management, and technical deliverability work before any campaign launches.
What is the difference between cold email and email marketing?
Cold email is outbound, sent to people who have not opted in, focused on generating first conversations and meetings. Email marketing typically refers to campaigns sent to opted-in subscribers, focused on nurture, education, re-engagement, and conversion. Qoulomb runs both, often in parallel, as part of a single integrated revenue programme so your brand stays visible at every stage of the buyer journey.
How much do B2B email marketing services cost?
B2B email marketing retainers typically range from $1,500 to $12,000 per month depending on the number of campaigns, list size, platform management, and whether cold outbound is included. Qoulomb offers plans starting under $1,000 per month for early-stage teams and scales with you as your programme grows. Book a demo and we will recommend a plan that fits your goals and budget.
Do you work with our existing HubSpot setup?
Yes. We work natively in HubSpot for email automation, sequence management, list segmentation, and pipeline reporting. If you have an existing setup we will audit it before starting, fix what is broken, and build on what is working. If you are starting from scratch, we set up the full HubSpot email infrastructure for you.
How long before we see results from email marketing?
Cold outbound sequences typically generate first replies and meetings within 2 to 4 weeks of launch. Drip and nurture campaigns show measurable pipeline impact within 60 to 90 days as leads move through the sequence. Newsletter performance compounds over 3 to 6 months as list quality and engagement build. We track leading indicators from week one so you see progress before the pipeline shows up.
How do you avoid the spam folder?
Deliverability is a technical and behavioural discipline. We set up SPF, DKIM, and DMARC records correctly, warm up new sending domains gradually, keep list hygiene tight by suppressing bounces and unengaged contacts, avoid spam-trigger words in subject lines, and monitor sender reputation scores weekly. Most of our clients see inbox placement above 95 percent.
Can email marketing work for niche or technical B2B products?
It often works better in niche markets. A smaller, more specific audience means higher relevance when you get the messaging right. We have run email programmes for chemical commerce platforms, manufacturing software companies, and deep-tech SaaS products. Our writers understand complex products and write copy that earns the trust of technical buyers rather than alienating them.
How do you measure the ROI of email marketing?
We track email performance across three layers: deliverability and engagement (open rate, reply rate, click rate, unsubscribes), lead conversion (form fills, demo bookings, and meetings generated from email sequences), and pipeline attribution (revenue influenced by email touches across the sales cycle). Monthly reports connect every campaign to business outcomes, not just email statistics.
