Who we work with
We work with newsletter owners across the UK and around the world. Most of them fall into one of three groups.
UK creators & writers
Independent writers, experts and creators who want a newsletter that grows and pays, without spending every week on sends, design and admin.
Media & publishers
Media brands and publishers running one or more newsletters who need extra hands on production, audience growth and ad sales.
B2B brands & founders
Companies and founders using a newsletter to build trust, win leads and stay front of mind, with LinkedIn and SEO feeding the list.
Why a London‑based team
Open Rate Media is the newsletter agency brand of Calu Media Group, and our team of 6 is based in London. Most of our work happens remotely, which is how we work with clients around the world, but UK clients get a few extra benefits.
Founded in 2024, we have worked with 25+ clients and driven 200k+ subscribers for them so far.

Frequently asked questions
Are you based in London?
Yes. Open Rate Media is a London-based newsletter agency and part of Calu Media Group. Most of our work happens remotely, and we are happy to meet clients in person in London when it helps.
Do you only work with UK clients?
No. We work with newsletter owners across the UK and around the world. Being in London simply means UK clients get a team in their own time zone.
What does a newsletter agency do?
A newsletter agency runs some or all of your newsletter for you. That can mean writing and editing issues, designing templates, managing sends and deliverability, growing your subscriber list and earning revenue through sponsorships, ads or paid subscriptions. We can take on the whole operation or just the parts you would rather hand over.
Which newsletter platform do you use?
We are an official beehiiv Expert Partner and beehiiv is the platform we know best, so most of our work happens there. We handle new beehiiv launches and migrations from platforms such as Substack, Mailchimp and ConvertKit (now Kit).
Can you help with UK GDPR for my newsletter?
We set up sign-up forms, consent wording and list management with UK GDPR and PECR in mind, and keep your list clean. We are not lawyers, so for anything beyond good practice we will recommend you take proper legal advice.
How long does it take to grow a newsletter?
There is no fixed timeline. Growth depends on your niche, your content, how often you publish and the channels and budget you use. Most newsletters build steadily over months rather than weeks, so we focus on consistent publishing and growth channels that compound over time. We will never promise a subscriber number we cannot stand behind.
