We know how email marketing agencies run.
Most accountants treat every business the same. We work only with agencies, so we already understand your model before you explain it.
Recurring revenue you can actually plan around.
Retainers are predictable. We turn that into real forecasting so you can hire and invest with confidence.
Software and tooling costs add up quietly.
ESPs, automation tools, deliverability software. We track them against revenue so margin stays healthy.
Lean teams, sharp tax planning.
Smaller teams, higher margins, more profit to plan around. We make sure you keep as much of it as possible.
Why email marketing agencies
need a specialist.
A generalist keeps you compliant. A specialist makes the numbers work as hard as you do.
Proactive tax planning.
Agency income is rarely smooth. We plan ahead across the year so email marketing agencies are not overpaying tax or scrambling at year end.
Financial strategy that scales.
Payroll, freelancers, pricing and margin. We help you grow without the profitability quietly slipping away underneath you.
Real-time agency insight.
Monthly management accounts and fractional CFO support, so you always know your margin, your runway and your next move.
One system. Two levels. Get to the end game.
The foundation keeps your books clean, your tax planned and your numbers understood. The next level turns them into growth: sharper pricing, stronger margins, cash you can forecast. Run both, and exit planning becomes the end game: a buyer-ready business that’s yours to sell at full value. Sidekick gets you there, from day one.
The
foundation.
Bookkeeping, tax planning, accounts, VAT and management reports done properly, on time, in plain English.
The
next level.
Financial infrastructure, strategic clarity and hands-on advisory built specifically for agencies. We install the systems, deliver the insight, and stay on it.
Both levels build towards the same destination: a business that’s commercially attractive and buyer-ready, whether you sell in 1 year or 5. We help you build towards it from day one, so when the offer comes, you keep more of it.
When the numbers are clean and the strategy is right, email marketing agencies grow with confidence. That is the work.
Results that speak for themselves.
Here’s what changed when we built the financial layer underneath, in the numbers and in their words.
One of the absolute best in the game. Thoroughly enjoy working with Rayhaan. Still actively working with him and intend to do so over the long term. He's been a game-changer for my business and is a thorough gentleman and really does go above and beyond.
Rayhaan is brilliant. Highly responsive & up for tackling complex challenges. We had an unreasonably tricky business model which he rose to the challenge of handling. I feel confident in our numbers with his expertise at hand.
Everybody wants clarity. My stress levels have decreased and I'm able to operate at a higher level, the biz is performing much better as a result.

What email marketing agencies ask us.
How much should an email marketing agency charge for a retainer in the UK?
UK email retainers commonly run from around £1,500 a month for a focused campaign programme to £5,000 or more where strategy, design, build and CRM management are all in scope, and the spread is about scope rather than going rates. Price yours from the inside: cost the delivery hours and tools each client needs, add the margin the agency must make, and let that set the floor. Then cap the scope in writing, because flows and campaigns multiply quietly.
Software costs keep climbing. How do I stop them eating my margin?
Split the stack in two: tools that exist because clients do, which belong in delivery costs and ideally in the price of each retainer, and tools that run the agency, which are overheads to review twice a year. Track the client-serving tools per account, because an ESP seat here and a testing tool there can quietly take five points off an account's margin. Anything priced per contact or per send needs watching hardest, since it scales with the client's success but not with your fee.
Should clients pay for their own ESP, or should I buy it and recharge?
Have clients hold their own ESP contracts where you can. They keep their data and history if you ever part ways, the subscription never touches your margin, and you avoid rebilling software with VAT added on top. Buying centrally can be cheaper on agency plans, but then price it into the retainer properly with headroom for list growth, or the subscription line becomes a slow leak.
What is the most tax-efficient way to pay myself from my agency in 2026/27?
For most owners it is still a small salary plus dividends: salary up to the £12,570 personal allowance, then dividends from post-tax profit. Dividends carry no National Insurance and are taxed at 10.75% in the basic band and 35.75% in the higher band for 2026/27, with only the first £500 tax free, and the company pays corporation tax at 19% to 25% before paying them. The right mix shifts with profit levels and pension plans, so review it every year rather than setting and forgetting.
My revenue is recurring, so why do tax bills still catch me out?
Because tax runs on a different clock: VAT leaves in quarterly lumps, corporation tax accrues invisibly on every profitable month and lands long after year end, and a growing agency's bill is always bigger than last year's. The fix is mechanical: a separate tax account fed a fixed percentage of every month's receipts, sized so the money is already sitting there when each deadline arrives. Recurring revenue makes this easier than in any other agency model; there is no excuse for a tax surprise on a retainer book.
