Companies Using Campaign Monitor in London: 88 Active Firms (2026)
Companies using email marketing software send consent-led newsletters, customer updates and campaign journeys from websites across London.
Marketing, revenue operations and web teams are the usual buying centres here, with adoption signalling an organisation that treats email as an owned customer channel rather than an occasional broadcast tool. Companies running this email-marketing stack tend to be SMB or mid-market operators with subscription lists, booking flows, ecommerce baskets, member communities or professional-services pipelines to nurture. Engagements are usually modest in licence cost but operationally sensitive: value sits in clean contact capture, audience segmentation, deliverability, campaign reporting and links between web forms, CRM, ecommerce and service workflows. The cohort therefore suggests teams with some repeat marketing cadence, even where the wider business remains owner-managed or lightly staffed.

London has 88 actively trading companies with this email-marketing platform detected on their public websites. Reported employment across the same adoption cohort totals 1,204 people, pointing to a base that includes lean agencies, publishers, leisure operators and customer-facing service firms rather than only software-heavy businesses. The sector mix is consistent with repeat-engagement use cases: editorial updates, event reminders, booking nudges, distributor promotions and client-development sequences. A small minority appear to sit above mid-market turnover thresholds, so most usage looks embedded inside marketing operations rather than attached to enterprise-scale procurement programmes.
PECR and UK GDPR put permission, identity and opt-out handling at the centre of UK email marketing. ICO guidance says electronic mail marketing to individuals needs specific consent unless the soft opt-in applies to previous customer relationships for similar products or services. Senders must not disguise who they are and need a valid route for unsubscribe or opt-out requests. Corporate-body email is treated more permissively, but suppression lists for objecting businesses remain expected practice. Market structure is fragmented around list capture, consent storage, template production, analytics and CRM hand-offs, with the Data & Marketing Association and IAB UK providing sector reference points.
Adoption appears likely to follow marketing-operations discipline more than appetite for stand-alone newsletter tools. Companies running this stack tend to keep it when subscriber lists, templates and preference centres are embedded in day-to-day workflows, but migration pressure builds where CRM suites, ecommerce platforms or website builders bundle comparable email functions. Privacy expectations also push teams towards cleaner consent trails and more cautious segmentation. For smaller London users, the practical question is less whether email remains useful and more whether a separate email platform justifies the admin, deliverability monitoring and integration work it requires.

Key facts
About 5% of the trading cohort reports turnover above £5M (5 of 88 firms) — the rest sits below that revenue band.
9% of the cohort was incorporated since 2022 (8 firms), so a sizeable share is in its first few filing cycles.
PECR, UK GDPR and the Data Protection Act frame consent-led email marketing; ICO guidance requires specific consent or the limited soft opt-in for individuals, no disguised sender identity and a valid opt-out address.
The DMA’s Email Benchmarking Report 2024 says UK email volumes reached 381 billion in 2023, a 14% year-on-year increase.
B2B email delivery rates fell from 96.8% in 2022 to 92.1% in 2023, so stale contacts and suppression lists remain practical operating issues.
Among London users, 59.1% also run web analytics, 52.3% use a CDN or site-security layer and 37.5% use tag-management tooling.
Sector coverage overlaps, but Media & Publishing accounts for 17.0% of the London cohort; Sport & Leisure, Wholesale & Distribution and Marketing Agency each account for 10.2%.

Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
