EMAIL, MANAGED
Turn email into a reliable revenue channel
We run email channels for UK organisations and businesses, end to end: strategy, copy, delivery, reporting. Charities, membership bodies, brands. Start with a free audit: connect Mailchimp with an API key, or paste a recent send if you’d rather not share one.
Postroom is new. The Hendrix and AdShare agency archive behind it goes back to 2010.
Why Postroom
Most organisations send emails. We build revenue systems.
Most organisations send emails. Very few build systems that perform.
Structured Campaign Planning
Campaigns planned around your key moments, not reactive sends. Aligned to clear revenue, sales or donation goals, not just activity.
Segmentation That Converts
Target the right people with the right message. Driven by behaviour, intent, and past engagement.
Email Journeys (Not One-Offs)
Welcome flows, customer and donor journeys, retention sequences. Built to move people from first touch to long-term customer or supporter.
Ongoing Optimisation
Continuous tracking, testing and refinement, so performance improves month on month instead of resetting with every campaign.
Why most email marketing fails
Most organisations send glossy, design-heavy emails that look impressive but don’t convert. They get lost in Promotions tabs, skimmed over, or ignored. We’ve been fixing this for UK organisations since 2010 (the start of our Hendrix and AdShare agency archive), much of it in charity fundraising, including the Muslim charity sector, one of the hardest inboxes in the country. That is where we know the problems usually sit.
- Emails look polished, but don't feel personal
- Messaging is broad, with no meaningful segmentation
- Campaigns are sent reactively, not strategically
- Where trust and timing matter, emails need to feel sincere, simple and human, not like marketing.
How it works
Quick, hassle-free set-up. We plug into the email platform you already use and handle the rest.
We build the sequences, run the sends and let automation handle the routine ones. You see the plan before anything goes out and a report after it does.
Our Process
Three steps from audit to inbox
Run a free audit
Connect Mailchimp with an API key, or paste a recent send if you would rather not share a key. The audit takes a few minutes. You get a score out of 100, the three biggest gaps in revenue order, and a reading written for the people who run the organisation, not engineers.
Walk the findings together
Thirty-minute call. We talk through what the audit surfaced, where the highest-revenue fix is, and what good would look like for your programme. No pressure to sign anything. Some organisations are happy to take the audit away and act on it themselves. That's fine. The audit was free for a reason.
Pick the right tier
Foundation, Growth, Revenue Partner, or Audience Access. The audit tells us which one fits. We onboard you, agree the campaign calendar against your year (Ramadan, year-end, Black Friday, Christmas, a winter emergency), and get the first month of sends in the inbox.

How we read an account
The Microsoft deliverability problem, and how we approach it
Hotmail, Outlook and Live addresses make up a large share of the UK Muslim charity lists we have looked at. When sender reputation slips with Microsoft, that part of the list goes quiet while Gmail and Yahoo keep delivering.
The rolled-up open rate looks “disappointing but fine” rather than catastrophic, so nobody catches it. We read the account provider by provider, which is how it surfaces in an audit.
Repairing it is slow, careful work. We have done it before: authenticate the domain properly, clean the list, send to your most recent people first, and widen only as Microsoft starts opening mail from that domain again.
Gmail, Yahoo and Microsoft judge a sender separately. We split results by provider, so a problem hiding inside a healthy-looking total shows up.
Authentication first, then list hygiene, then recency-first sending: your most recent and most engaged people before anyone else.
Reputation recovers at the inbox providers' pace, not ours. That is why the work begins well before a peak season.
Credentials
Postroom is new. The work underneath it is not
Who it’s for
Built for UK organisations and businesses that need email to perform
Charities and nonprofits
The sector we know deepest: appeals, seasonal campaigns and supporter journeys, including Muslim charities, where the inbox is hardest and the calendar is decided months out.
Businesses and brands
Service firms, ecommerce, professional practices. The same method applies: the newsletters, launches and lifecycle journeys that keep a list warm and turn readers into customers.
Membership and community organisations
Associations, CICs, faith groups, clubs. Journeys that inform, renew and move members to act, in a voice that sounds like you rather than like marketing.
Your calendar
We know when your audience is listening
Every organisation’s year has rhythms. Ramadan, year-end, Black Friday, Christmas, a winter emergency, a product launch: the moments your calendar turns on are decided months out. Most organisations only send at peak. We build programmes that work year-round, so when your season comes, your list is warm, segmented and ready.
Re-permission the list, renewal and regular-giving asks while resolutions are fresh, build the spring plan.
Begins around 8 February 2027. For Muslim charities, the biggest giving month of the year, decided months out.
Eid al-Fitr around 9 March. Thank-you sequences, impact reports, spring launches and appeals.
Regular asks while the season is warm. The tax year ends 5 April: last call on this year's giving, first call on next year's budgets.
Eid al-Adha and Qurbani for Muslim charities. Events, challenge fundraising and summer launches open.
Impact stories, customer and supporter surveys, mid-year reviews.
Re-engagement, suppression clean-ups, summer education while the inbox is quiet.
Deliverability groundwork begins. Your winter appeal, and your fourth quarter, are decided here.
Fix the sending set-up. Back-to-work launches, harvest appeals, autumn renewals.
Separate openers from the addresses costing you. Prep Black Friday and winter creative.
Black Friday, cold-weather appeals, emergency follow-through, Giving Tuesday.
Christmas sends, tax-efficient giving, year-end stewardship, January planning.
Your calendar will look different depending on what you do and who you serve. Islamic dates shown are for 1448 (2027) and shift every year. Postroom plans your sends well ahead of every key moment.
