Questions
- How much does an outbound agency cost?
- 30 of the 63 publish a monthly minimum, from $397 to $10,000, with a median of $5,000. 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, 4 agencies offer pay-per-meeting pricing and 4 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?
- 26 of the 63 build on Clay and 15 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.
