01 Automation, on display

Flows that run on autopilot and improve with every send.

Most email marketing firms treat every subscriber the same way: one template, one send time, one generic offer. We build flows that react to what subscribers actually do. Pick a flow to see how it's structured.

TriggerSubscriber joins your list
Email 1Welcome and brand story
WaitLet them settle in
Email 2Best sellers and social proof
GoalFirst purchase

Illustrative structure. Every flow we build starts from your customer data, not a template library.

02 The full stack

Everything our email company delivers.

We don't hand you a template and disappear. Every deliverable is built, tested, and reported on in-house, at a fraction of the cost of building the same team yourself.

Nº 01

Email Strategy & Roadmap

We audit your current list, competitors, and past sends, then build a 90-day plan tied to revenue targets, not vanity metrics.

Nº 02

List Segmentation & Growth

Behavioural segments, sign-up forms, and lead magnets that grow your list with people who want to hear from you.

Nº 03

Campaign Design

On-brand HTML templates that render cleanly across Gmail, Outlook, and Apple Mail.

Nº 04

Marketing Automation & Flows

Welcome series, cart recovery, win-back, and post-purchase flows that run on autopilot.

Nº 05

Cold Email Outreach

As a cold email agency for B2B pipelines, we write and warm up outbound sequences built to book meetings, not trigger spam complaints.

Nº 06

White-Label Email Marketing

Agencies and consultants outsource to our team and keep the client relationship under their own brand.

Nº 07

Deliverability Management

Domain authentication, warm-up, and list hygiene so your campaigns land in the inbox, not the promotions tab or spam folder.

Nº 08

A/B Testing & Optimisation

Subject lines, send times, and CTAs tested continuously, with results rolled into the next campaign.

Nº 09

Reporting & Analytics

Weekly dashboards showing opens, clicks, and revenue per email in plain language.

What sets your retainer Most engagements start with a flat monthly retainer, so you know the exact cost before any campaign goes live. It depends on three things:

  • List size
  • Number of active flows
  • Custom design work

03 How an engagement runs

From brief to inbox in seventy-two hours.

Campaigns move from brief to inbox in days, not the multi-week cycles typical of larger, slower shops. Most clients are live with their first campaign inside two weeks of signing on.

0hBriefGoal, offer, and segment agreed
24hCopy & designSubject lines and on-brand template
48hTestRendered across inboxes before a single send
72hSendLive, then reported in plain language

Audit & Strategy

We review your list health, past campaigns, and competitors, then map a plan against clear revenue goals.

List & Segments

Sign-up flows, lead magnets, and behavioural segments that put the right message in front of the right subscriber.

Build & Automate

Templates, copy, and automated flows go live, tested across inboxes before a single send reaches your list.

Test & Scale

Ongoing A/B tests and monthly reporting turn early wins into a repeatable, scalable revenue channel.

04 Behind the numbers

One number matters: revenue per send.

Email is the highest-ROI channel you own, and it deserves the same strategic attention as paid media or SEO. Every campaign starts with your customer data, not a template library. 9+ years running email programs and 180+ campaigns launched monthly.

01

Senior Strategists, Not Account Managers

You work directly with the person building your flows, not a rotating point of contact reading updates off a spreadsheet.

02

Revenue-First Reporting

Every report ties back to money generated, so you always know exactly what your email program is worth.

03

Deliverability Built In

We monitor sender reputation weekly, not quarterly, so a spam-folder problem gets caught before it costs you a launch.

04

Fixed Turnaround Times

Campaigns move from brief to inbox in days, benchmarked against industry data like the Litmus State of Email Deliverability report.

07 The store policy

Why brands choose this email company.

Plenty of vendors can schedule a send. Fewer can tell you why it worked, or didn't. Email connects to your paid campaigns, SEO, and social media work instead of sitting in a silo.

Strategy Before Software

We choose the platform after the plan, so the tool fits your business instead of the reverse.

Transparent Reporting

No vanity dashboards. You see opens, clicks, and revenue in the same report, every month.

Dedicated Team

A strategist, copywriter, and designer assigned to your account, not a rotating pool of freelancers.

Fast Onboarding

Most clients are live with their first campaign inside two weeks of signing on.

No Long Lock-In Contracts

Month-to-month agreements, because results should be what keeps you here.

Full-Funnel Thinking

Email works alongside your paid, SEO, and social work.

What's included when I hire your email management service?

At GD Digital Marketing, we handle strategy, segmentation, copywriting, design, automation, and reporting, the full email marketing agency workflow, so you don't need to hire or manage each role separately in-house.

What should I look for in an email marketing company before signing a contract?

Look past the platform certifications. The best email marketing company will show you past campaign data, explain their segmentation approach, and tell you exactly how they measure success before you sign anything.

What does email marketing agency pricing typically include?

Pricing depends on list size, the number of active flows, and how much custom design work is involved. Most engagements start with a flat monthly retainer, so you know the exact cost before any campaign goes live.

Do you offer cold email outreach for B2B teams, or only newsletters?

Yes. As a cold email marketing agency for B2B pipelines, we build and warm up outbound sequences alongside your regular newsletter and lifecycle campaigns, so both channels work from one shared list strategy.

Can I hire you if there's no email marketing agency near me locally?

Yes. Strategy calls, campaign builds, and reporting all happen remotely over video and email, so location never affects turnaround. Most of our current clients aren't based in the same city as our team.

Can you handle bulk email marketing services for a large, older list?

Yes. Large or inactive lists just need extra care first. We clean, re-permission, and warm the list before any high-volume send, so your sender reputation stays protected instead of getting flagged as spam.
