How to compare done-for-you outbound agencies
- Ask what you get: a list of leads, a reply, or a booked call on your calendar.
- Ask which channels they run. Some use phone and LinkedIn. Some use email only.
- Ask if they send from your main domain or from separate sending domains.
- Ask who answers replies, and how fast, including nights and weekends.
- Ask what is in the monthly fee: data, domains, inboxes, and software.
- Ask for the agreement in writing before you pay.
Which agency is best for $10k+ B2B deals?
There is no single best agency. Larger firms such as Belkins, CIENCE, Martal, and SalesHive run teams of SDRs across several channels. Outbound System focuses on cold email. Sales.co runs several channels from a stated price of $2,000 a month.
SyncSolved is a good fit when you want email only, a team that answers replies in minutes, calls booked inside the email thread, and separate sending domains so your real domain stays safe. It is not a fit if you need live phone calling. As of October 2026, it starts from $2,500 a month.
Why does deal size matter?
Done-for-you outbound takes daily work: research, list checks, domains, warmup, replies, and booking. That cost is easier to pay back when one sale is worth $10,000 or more.
Where does this information come from?
The table uses each agency's own website, checked on October 24, 2026. We did not test these firms. Check each site for current prices and terms before you decide.
