The emailing agencythat lands inbox, segments, automates, converts, stays compliantinbox first, revenue next.

An emailing agency that builds email marketing programs that actually land. Most teams obsess over the design and ignore the part that decides everything: deliverability. We fix SPF, DKIM and DMARC, warm your domain and watch sender reputation, segment off real behaviour, build the automations that compound, and A/B test the rest, the RGPD-compliant way, so your email reaches the inbox and earns its place.

What we do

An emailing agency that lands in the inbox, not just sends.

Anyone can schedule a newsletter. Getting it past the spam filter, segmenting it to the right people, automating the flows that convert, and keeping it compliant is a different job. Here are the four things we own.

Method · 4 stages

We treat email like infrastructure, not a blast.

Most emailing programs fail the same way: a list nobody cleaned, a domain nobody authenticated, a campaign blasted to everyone, and a slow slide into the spam folder. So we build it in order: deliverability foundations first, then segmentation and flows, then templates and testing, then honest reporting, so what you send actually reaches people who want it.

  • Audit · deliverability, list quality, consent and the flows you are missing
  • Foundations · SPF, DKIM, DMARC, warmup and reputation before we scale sends
  • Build · segmentation, automations and templates wired to your ESP and CRM
  • Optimise · A/B testing, list hygiene and reporting so it keeps improving

Differentiator · no bought lists

We fix deliverability before design.

We do not sell pretty templates over a broken foundation. We align authentication, warm your domain, clean your list and protect your sender reputation first, because a campaign that lands in spam converts nobody. And we never buy or rent lists. A compliant, engaged list beats a big one every time, for the inbox and for the law.

  • Deliverability first, design second: we fix authentication and reputation before we make anything pretty, because a campaign in spam converts nobody.
  • We never buy or rent lists, and we will tell you to drop the ones you bought. Bought lists wreck your reputation and break consent rules. There is no version of that we run.
  • You own the program: it lives in your ESP and CRM with your consent records, so your team keeps it running without us holding the keys.
  • No vanity dashboard. We are judged on inbox placement, engagement and revenue per email, not on how many you sent.

What we set up

Deliverability at the core, your email program around it.

We configure the parts that turn email into reliable revenue, then connect them to how your business already runs. Here is what a real emailing program covers.

Free audit · 60 minutes

We map where your email leaks, you leave with a plan.

Before quoting anything, we take 60 minutes to look at your deliverability, your list quality, your consent basis and the flows you are missing. You leave with an honest read on what is keeping you out of the inbox, what to fix first, and which automations are worth building. Zero pitch, just a straight take on your email program.

  • An honest read on your deliverability and list quality
  • The authentication and reputation work to wire first
  • The segments and automations worth building
  • A frank take on what email will not fix for you

Our approach

How we run an emailing program.

Five steps, in order. We do not scale sends before authentication and reputation are wired, we do not ship flows without consent baked in, and your team owns the program at the end. Each step has a deliverable and you sign off before we move on.

  1. Step 1 · Email audit

    See where your email actually leaks

    We look at the real picture: are you authenticated with SPF, DKIM and DMARC, where do your sends land, how clean is your list, what is your consent basis, and which flows you should have but do not. Half the value is an honest read, including telling you if your list quality or consent problems mean no agency can fix the results until you fix the source.

  2. Step 2 · Deliverability foundations

    Get authenticated and trusted before you scale

    We align SPF, DKIM and DMARC on your sending domain, set up warmup for new domains or IPs, split transactional and marketing streams, and wire reputation monitoring in Google Postmaster and Microsoft SNDS. This is the unglamorous work most agencies skip, and it is what decides whether the rest of the program ever reaches an inbox.

  3. Step 3 · Segmentation & flows

    Build the segments and automations that compound

    We segment your list on behaviour, lifecycle and engagement, run hygiene to suppress dead and non-consenting addresses, and build the flows that earn revenue on autopilot: welcome, abandoned cart, post-purchase, win-back, lead nurturing. Each flow is mapped to a trigger, templated to render everywhere, and shipped with consent baked in.

  4. Step 4 · Templates & testing

    Make it render, then test it relentlessly

    We code responsive email templates that survive Gmail, Outlook and Apple Mail, then A/B test the levers that move results: subject lines, preview text, send time, content blocks. We connect your ESP to your CRM and site so data flows automatically, and we use AI for variant drafting and list cleanup so your team ships more without growing headcount.

  5. Step 5 · Optimise & hand over

    Report honestly, then leave you running it

    We report on what matters: inbox placement, open and click trends, conversions, unsubscribe and spam-complaint rates, not vanity volume. We tune flows, keep the list clean and the domain warm, and document the program in your ESP so your team owns it. If you want us on retainer for the next phase, we talk about that separately, never as a condition.

Proof · what the teams say

We're judged on the email that lands.

No partner badge to display, so we lead with what matters: feedback from the teams whose email program we built, and whether their email kept landing and converting after we left. Our Trustpilot reviews come from those teams, not from a marketing deck.

  • The program lives in your ESP and CRM, owned by your team
  • Deliverability and reputation wired before we scale any send
  • Flows built on consent, tested, and kept clean
  • Trustpilot reviews come from the teams we built it for

FAQ · Emailing agency 2026

The questions we get asked on repeat.

  • What does an emailing agency actually do?
    An emailing agency runs your email marketing end to end so it lands and converts, instead of leaving you guessing why your campaigns hit spam. We fix deliverability first (SPF, DKIM, DMARC, warmup, sender reputation), segment your list off real behaviour, build the automations that compound (welcome, abandoned cart, win-back), code templates that render everywhere, and A/B test relentlessly. The point is email that reaches the inbox and earns revenue, the RGPD-compliant way, not a prettier newsletter nobody sees.
  • How much does an emailing program cost?
    It depends on scope: a deliverability cleanup and a few core flows is nothing like a full program across segmentation, automations, templates and ongoing A/B testing. We do not throw out a flat package. We start with a free 60-minute audit to find where your email actually leaks, then quote a fixed scope. Your ESP subscription (Brevo, Mailchimp, Klaviyo, SendGrid) you pay the platform directly; we set it up so the spend stays predictable.
  • Why do my emails land in spam or the promotions tab?
    Usually because the foundations are missing, not the copy. If your sending domain is not aligned with SPF, DKIM and DMARC, if you blast a cold or bought list, or if your reputation is already damaged, providers filter you out before anyone reads a word. We align authentication, warm the domain, clean the list, separate transactional from marketing streams, and monitor reputation in Google Postmaster and Microsoft SNDS. Deliverability is the first thing we fix, because nothing else matters until your mail lands.
  • Which ESP should we use, Brevo, Mailchimp, Klaviyo or SendGrid?
    It depends on your model. Klaviyo is strong for ecommerce flows and product data, Brevo and Mailchimp cover marketing plus transactional well, Kit suits creators, and SendGrid is built for high-volume transactional sending. We do not push one platform for a commission. In the audit we pick the ESP that fits your volume, integrations and automation needs, then set it up and wire it to your CRM. If you are already on one, we usually work with it rather than force a migration.
  • Can you set up automations and flows for us?
    Yes, and that is where email compounds. We build the flows that earn revenue without a manual send: welcome series, abandoned cart, post-purchase, win-back, re-engagement before sunset, and lead nurturing for B2B. Each flow is mapped to a trigger, templated to render across clients, and A/B tested on subject line, timing and content. We wire them to your ESP and CRM so they fire on real behaviour, and we keep consent and suppression in place so the program stays compliant.
  • Do you handle RGPD and consent?
    Yes, and we treat it as non-negotiable, not a checkbox. We build on opt-in, keep your consent records clean, honour unsubscribes fast, and suppress anyone who has not agreed to hear from you. We will not buy or rent lists, and if you bought one we will tell you to drop it, because it wrecks your reputation and breaks consent rules. A compliant, engaged list is worth more than a big one, for deliverability and for the law.
  • When is an emailing agency NOT the right fit for us?
    If you want us to blast a bought list, we are not your agency, that is a fast way to torch a domain and break the rules. If your list is tiny and has no consent, the honest answer is to fix collection first, not to send harder. And deliverability is not a one-time job: reputation needs ongoing care, list quality and consent decide your results more than any clever subject line. If you want a single magic blast and no maintenance, email is the wrong channel to expect that from.
  • How long until we see results from email marketing?
    Deliverability fixes and a first core flow can land in 2 to 4 weeks: audit and authentication first, then warmup, segmentation and a welcome or abandoned-cart flow. A full program across multiple automations, templates and ongoing testing runs longer. We work in batches so you get inbox placement and a revenue flow live early, rather than waiting on a big launch before a single email reaches a customer. Real results depend on list quality and consent, which is why we fix those first.
