Your UK B2B cold email agency

We can launch in three weeks. That time allows us to define your ICP, source and double-verify data, and create messaging sequences that resonate with busy decision-makers. Trying to move faster often means cutting corners on targeting or compliance, which risks poor delivery and weaker results. Three weeks gives us the solid foundation for outreach that works from day one.

Cold email is designed to spark sales conversations, so the key metrics are replies and opportunities. Results vary depending on your market and goals, but most clients see genuine responses and qualified leads in the first few weeks. To give you confidence, we publish two years of live campaign performance data (which is updated daily) so you can see exactly how Sopro campaigns perform across industries.

Not much. We manage the heavy lifting, from building prospect lists and writing copy to running campaigns and monitoring replies. Your role is simple: join onboarding calls, pick up the leads we generate, and give feedback so we can fine-tune campaigns. The more insight you share about your ideal customers, the better we can tailor outreach to your market.

Yes. All data is yours to keep forever. That includes verified contact details, reply history, and enriched prospect information mapped to your ICP. You can use it across sales, marketing, or CRM systems long after the campaign has ended, making every outreach project a long-term investment.

Yes, when it’s done right. Bad cold email (bought lists, generic templates, spammy cadences) gives the channel a bad name. But with verified data, personalised sequences, and compliance-first practices, cold outreach remains one of the fastest ways to open doors with senior decision-makers.

Not with Sopro. Deliverability is a huge part of our process. We manage sending domains, warm-up, cadence spacing, and messaging to protect your reputation and ensure emails land in inboxes.

It’s easy to think that scaling up any sort of marketing messaging ends up diluting the quality, but we do things differently. Our copywriters build bespoke sequences and then use Sopro’s AI engine, which is trained on over 100M live prospecting emails, to scale personalisation without losing the human touch. Every message feels direct, relevant, and written for the individual.

In our experience, it’s going too broad. Many businesses waste effort by blasting generic messages to poorly matched lists. We flip that on its head, leveraging cold email as a channel to execute account-based engagement strategies. every campaign starts with ICP mapping, so you’re only talking to the right roles in the right companies with the right message.
