Cold email agency vs SDR

Updated October 7, 2026. Prices read October 7, 2026.

A cold email agency is a flat monthly fee for a managed email program, from $2,000 a month at Sales.co. An outsourced SDR team is priced per person, from $11,950 per 4-week engagement for one SDR at SalesRoads. The right pick depends on whether your buyers answer email or the phone.

An SDR you hire adds salary, commission, tools and management time; CIENCE lists US SDR levels at $4,500 to $6,500 a month. Sales.co is our own service, so read this page with that in mind.

What this page adds: one table that puts published prices for email agencies, outsourced SDR teams and SDR levels next to launch time and minimum term. It also adds the one source-of-booking count we can see: of 143 calls booked through Sales.co's own campaign, 98 named cold email and 17 named a cold call (Sales.co's conversion benchmarks).

The in-house row uses CIENCE's SDR level table for US SDRs, the nearest published figure we found. CIENCE adds commission on top, calculated from base salary and the share of target reached (times 0.35 below target and 0.7 at or above it, none below 60% of target). Tools, data, management time and benefits are extra and we have no published source for them, so they are left out. The SalesRoads engagement, by its own description, includes dedicated SDRs, a research and data team, a client strategist, a performance coach and an optimization specialist.

What the same money buys

One SalesRoads SDR for one 4-week engagement ($11,950) costs about as much as six months of Sales.co's smallest plan ($12,000). Two SDRs for 4 weeks ($16,750) cost about as much as eight months. The comparison is on price only; the two channels reach people differently.

How to decide

Ask where your last ten customers first heard from you. If email or LinkedIn started most of them, an email agency is the cheaper test. If the phone did, price an SDR. If you do not know, start with email: it costs less to learn from. In Sales.co's campaign 42 of 143 bookings (29%) came from companies whose contact never answered the email, and 22 of those 42 named cold email as how they heard about us. The numbers behind the email side are on is a cold email agency worth it.
