Cold email agencies in Europe
21 agencies in the index offer cold email and serve buyers in Europe. Ranked by the evidence on record, the first three are Belkins (Dover, US, from $5,000 a month), SalesCaptain (London, UK, from $3,500 a month) and Martal Group (Toronto, CA). Results depend as much on list quality and sending infrastructure as on copy, so ask who owns the domains, inboxes and data when the engagement ends. Europe is many markets at once, so outreach in the buyer's own language and attention to national rules matter more than volume. 7 of the 21 publish a monthly minimum, from $2,500 to $10,000, with a median of $3,500. 1 offers pay-per-meeting pricing and 1 offers pay-per-lead; the rest work on a retainer or do not say. Besides cold email, the services most often offered here are intent data, GTM engineering and LinkedIn outreach. 11 build on Clay, 5 work inside HubSpot and 9 use their own or undisclosed tools. 9 have a Clutch or G2 rating on file with the date it was read. Before signing, ask for a sample sequence, the definition of a qualified meeting and who owns the domains and data afterward.

Questions
- How much does a cold email agency cost?
- 7 of the 21 publish a monthly minimum, from $2,500 to $10,000, with a median of $3,500. Setup fees and minimum terms vary, so ask for both before comparing monthly prices.
- Retainer or pay-per-meeting?
- A retainer buys an agreed scope each month and suits a defined ICP with at least three months of runway. Pay-per-meeting moves the risk to the agency and suits offers with a short sales cycle. On this page, 1 agency offers pay-per-meeting pricing and 1 pay-per-lead.
- How long until results?
- New sending domains need two to three weeks of warm-up before volume goes out, and list building runs alongside it. Most agencies quote first meetings in weeks four to eight.
- Does the stack matter?
- 11 of the 21 build on Clay and 5 work inside HubSpot. Ask who owns the sending domains, the data and the workflows when the engagement ends; some agencies hand them over and some keep them.
