Hack'celeration Agency · Newsletter 2026The newsletter agencythat sets the strategy, grows the list, lands in inboxes, automates the flows, measures revenuemore subscribers, more revenue.
A newsletter agency runs your email newsletter end to end, because a template and a send button isn't a strategy. We set the editorial calendar, grow the list with opt-in lead magnets, set up deliverability so your emails land in the inbox instead of spam, and build the automations in your ESP, measured on engaged subscribers and revenue, not vanity opens.

GeminiA newsletter agency grows an audience, not just a send.
Anyone can pick a template and hit send. Growing an engaged list, landing in the inbox, and turning readers into revenue is a different job. Here are the four things we own.
- Strategy & editorial
A newsletter people actually want in their inbox
Most newsletters fail because nobody had a reason to subscribe. We start from the angle: who it's for, the promise that earns the open, the cadence you can hold. Then we build the editorial calendar, the templates and the writing voice so each send carries one clear idea, not a wall of links. A newsletter is a relationship, and the strategy is what keeps people reading past issue three.
See a typical setup - List growth
List growth that's opt-in, not bought
Buying a list kills your sender reputation and breaks RGPD. Real growth comes from a reason to subscribe: a lead magnet worth the email, signup forms placed where intent is high, and a website that converts readers into subscribers. We wire the forms, the welcome flow and the referral loops, and we track which sources bring people who actually open, not just a bigger number that never reads.
See the method - Deliverability
Emails that land in the inbox, not in spam
The best newsletter is worthless if it lands in spam. We set up SPF, DKIM and DMARC, warm up your sending domain, and watch sender reputation so your sends reach the inbox. We segment so you only mail engaged subscribers, prune the dead weight that drags your reputation down, and keep your list clean. Deliverability isn't a one-time fix, it's ongoing care, and we treat it that way.

Flows and reporting, wired into your stack
The compounding part is automation: welcome sequences, re-engagement flows, and segmentation that sends the right thing to the right reader. We build these in your ESP (Brevo, Kit, Mailchimp and others), wire A/B tests on subject lines and send times, and report on open, click and conversion, not vanity opens. We're an automation and AI agency first, so this plugs into your CRM and your funnel.

We run a newsletter like an asset, not a side task.
Most newsletters die the same way: bought a tool, sent a few issues, no editorial calendar, no growth engine, no deliverability care, and it quietly goes silent. So we treat it like an asset: a clear strategy and cadence, an opt-in growth engine, deliverability wired in, and automations that compound, all measured on engaged subscribers.
- Audit · your list, your ESP, your deliverability and where readers drop off
- Strategy · the angle, the cadence, the editorial calendar and the voice
- Grow · lead magnets, signup forms and the welcome flow, opt-in only
- Send & measure · automations, A/B tests, deliverability, engaged subscribers
We grow lists that open, click and buy.
We don't chase a bigger number. We grow an opt-in list the RGPD-compliant way, keep it clean so deliverability stays strong, and optimise for engaged subscribers and revenue. That's exactly what's missing when an agency hands you a template and calls it a newsletter.
- We run newsletters end to end (strategy, writing, design, growth, deliverability, automations), not just a one-off template handoff.
- Opt-in only and RGPD by default: no bought lists, double opt-in, and a clean list, because deliverability is the whole game.
- Measured on engaged subscribers and revenue, not vanity opens, so we optimise for people who read, click and convert.
- Honest about fit: a newsletter compounds slowly and dies without consistent content and a real reason to subscribe. We'll tell you if it's not your channel.
Your newsletter at the core, the growth engine around it.
We build the parts that turn a send into a growing, engaged audience, then connect them to your CRM and funnel. Here's what a real newsletter setup covers.
- Setup
Editorial calendar & templates
We build the calendar, the email templates and the writing voice so every send carries one clear idea and ships on a cadence you can hold, instead of a scramble the night before.
- Setup
Signup forms & lead magnets
We design the lead magnet, place the signup forms where reader intent is high, and wire double opt-in so the people who join actually want to be there and stay RGPD-compliant.
- Setup
ESP setup (Brevo, Kit, Mailchimp)
We set up your email service provider properly: lists, segments, tags, sending domain and templates, so the tool works for your newsletter instead of fighting it on every send.
- Setup
Deliverability (SPF/DKIM/DMARC)
We configure authentication, warm up the domain, and monitor sender reputation and bounce rates so your sends reach the inbox and stay out of the spam folder over time.
- Setup
Automations & flows
We build the welcome sequence, re-engagement flows and segmentation logic so the right subscriber gets the right email automatically, and the list keeps compounding without manual sends.
- Setup
A/B testing & reporting
We test subject lines, send times and content, and report on open, click and conversion, plus list growth and churn, so decisions come from data and not from guessing.
We audit your newsletter, you leave with a plan.
Before quoting anything, we take 60 minutes to look at your list, your sends, your deliverability and where readers drop off. You leave with an honest read on whether the newsletter is worth doubling down on, what to fix first, and how to grow it. Zero pitch, just a straight take on your channel.
- An honest read on whether the newsletter is worth it
- Where your list growth and deliverability leak
- The automations and segments worth building first
- A frank take on what it won't fix
How we run a newsletter program.
Five steps, in order. We don't chase list growth before the strategy is set, we don't send before deliverability is wired, and your team owns it at the end. Each step has a deliverable and you sign off before we move on.
- Step 1 · Newsletter audit
Look at your list, your sends and where readers drop
We start with the numbers: list size and how much of it is actually engaged, your open and click trends, your deliverability, and where subscribers stop reading. We check your ESP setup, your forms and your authentication. Half the value is telling you honestly whether the newsletter is worth doubling down on, or whether the audience and content reason aren't there yet.
- Step 2 · Strategy & editorial
Set the angle, the cadence and the calendar
We define who the newsletter is for, the promise that earns the open, and a cadence you can actually hold. Then we build the editorial calendar, the templates and the writing voice so each issue carries one clear idea. A newsletter that ships consistently with a real point of view beats a polished one that goes quiet after a month.
- Step 3 · Grow the list
Opt-in growth, the RGPD-compliant way
We design a lead magnet worth the email, place signup forms where reader intent is high, and wire double opt-in and a welcome flow. We never buy lists: they wreck deliverability and break consent rules. We track which sources bring subscribers who actually open, so the list grows with people who read, not a vanity count that quietly churns.
- Step 4 · Send & automate
Automations, segmentation and deliverability
We build the welcome sequence, re-engagement flows and segmentation in your ESP, set up SPF, DKIM and DMARC, warm the domain, and monitor sender reputation so sends land in the inbox. We A/B test subject lines and send times and only mail engaged subscribers, so your reputation stays strong and your open rate reflects real readers.
- Step 5 · Measure & hand over
Report on what matters, then make it yours
We report on engaged subscribers, click and conversion, list growth and churn, not just opens. The strategy, calendar and flows live in your ESP and your docs so your team can run it without us. If you want to go deeper, our training covers the editorial and growth playbook end to end. If you want us on monetisation and scale, we talk about that separately.
We're judged on the list that engages.
No badge to display, so we lead with what matters: feedback from the teams whose newsletter we run, and whether they kept an engaged, growing list after we left. Our Trustpilot reviews come from those teams, not from a marketing deck.
- The strategy and flows live in your ESP, owned by your team
- Opt-in growth and a clean list, protecting your reputation
- Deliverability monitored, not fixed once and forgotten
- Trustpilot reviews come from the teams we run newsletters for
The questions we get asked on repeat.
What does a newsletter agency actually do?
A newsletter agency runs your email newsletter end to end so it grows instead of going quiet after a month. We set the strategy and editorial calendar, write and design the sends, grow the list with opt-in lead magnets and signup forms, set up deliverability (SPF, DKIM, DMARC) so emails land in the inbox, and build automations in your ESP. The point is a newsletter with engaged subscribers and real revenue, not a bigger list that never opens.How much does a newsletter agency cost?
It depends on scope: a strategy-and-setup engagement is nothing like writing and sending every week plus running growth and deliverability. We don't throw out a flat package. We start with a free 60-minute audit to see whether the newsletter is worth investing in and where the gaps are, then quote a fixed scope. Your ESP subscription (Brevo, Kit, Mailchimp) you pay directly; we set it up so the cost stays predictable.How do you grow a newsletter list the right way?
With a reason to subscribe, never a bought list. We design a lead magnet worth the email, place signup forms where reader intent is high (your site, your content, a landing page), and wire double opt-in plus a welcome flow. Bought lists wreck your sender reputation and break RGPD. We track which sources bring subscribers who actually open and click, so the list grows with engaged readers, not a vanity number that drags deliverability down.Why are my newsletter emails landing in spam?
Usually authentication or reputation. Without SPF, DKIM and DMARC set up, mailbox providers don't trust your sends. Mailing a cold or bought list, or never pruning unengaged subscribers, drags your sender reputation down until even your real readers stop seeing you. We fix authentication, warm up the domain, segment so you only mail engaged subscribers, and clean the list. Deliverability needs ongoing care, so we monitor it rather than fixing it once.Which ESP should we use, Brevo, Kit or Mailchimp?
It depends on what you're building. Kit (formerly ConvertKit) is strong for creators and content newsletters with simple automations. Brevo handles transactional and marketing email well and fits RGPD-minded teams. Mailchimp suits broader marketing needs. We don't push one tool: in the audit we look at your list, your flows and your budget, then recommend the ESP that fits and set it up properly, lists, segments, sending domain and templates.How do you measure newsletter performance?
On engaged subscribers and revenue, not vanity opens. Open rate matters but it's noisy since privacy changes, so we lead with click rate, conversion, list growth net of churn, and how much of your list is actually active. We A/B test subject lines and send times, segment by engagement, and report on what moves the business. A newsletter that 5,000 people open and nobody acts on is worth less than one read and clicked by 500 who buy.Can a newsletter actually make money?
Yes, but slowly and only if it's built right. Monetisation comes from owning an engaged audience: selling your own product, driving conversions in your funnel, or sponsorship once the list is large and active enough to interest advertisers. None of that works on a list that doesn't open. We focus first on engaged subscribers and deliverability, because that's what every monetisation model depends on, then build the revenue layer on top.When is a newsletter NOT the right fit for us?
When you can't commit to consistent content, or there's no real reason for people to subscribe. A newsletter compounds slowly and dies without a steady cadence and a clear promise, so if nobody on your side can write or own it, the budget is better spent elsewhere. It also needs ongoing deliverability care, not a one-time setup. We'd rather tell you that in the free audit than sell you a channel that goes quiet in two months.
Stop sending into the void. Build an audience.
A 60-minute audit, your newsletter and deliverability mapped, a growth plan built on engaged subscribers. If your team can run it in-house after setup, we'll hand you the playbook. If we're the right fit, we run it.
