Outbound agencies in Europe
25 agencies in the index run outbound 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). Europe is many markets at once, so outreach in the buyer's own language and attention to national rules matter more than volume. 8 of the 25 publish a monthly minimum, from $2,500 to $10,000, with a median of $4,250. 1 offers pay-per-meeting pricing and 1 offers pay-per-lead; the rest work on a retainer or do not say. The services most often offered here are cold email, GTM engineering and intent data. 13 build on Clay, 6 work inside HubSpot and 11 use their own or undisclosed tools. 10 have a Clutch or G2 rating on file with the date it was read. Filter the table by budget, stack and pricing model to narrow the list.

Questions
- How much does an outbound agency cost?
- 8 of the 25 publish a monthly minimum, from $2,500 to $10,000, with a median of $4,250. 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?
- 13 of the 25 build on Clay and 6 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.
