Which outsourced SDR companies are best in 2026?
Short answer: on a published 7-point rubric, the top two are CIENCE and SalesRoads.

Callbox, Martal Group, Leadium and Abstrakt tie on 5 points and are ordered by review count. Belkins, memoryBlue, SalesHive and Sales Focus Inc follow. Every figure comes from the company's own pages or Clutch profile, checked on 3 Nov 2026, and is linked so you can recheck it.

What does an outsourced SDR cost in 2026?
Only four of the ten publish a figure. They use three pricing models:
- Per SDR: CIENCE charges $1,750 a month per offshore SDR or $3,500 per US/EU SDR, plus $2,000 for the campaign team and $499 for the platform. SalesRoads charges $11,950 per four weeks for one SDR, falling to $7,192 per rep at six. A Callbox pod, which is one dedicated SDR, costs $6,667 a month.
- Flat retainer or programme: Abstrakt starts at $5,000 a month. Belkins, Martal (Tier 1A) and SalesHive also charge flat monthly fees but do not publish the amounts.
- Per meeting: none of the ten publishes per-meeting pricing, and SalesHive says it has none. The closest is CIENCE's bonus on held meetings and Martal's commission on its higher tiers.
Before comparing headline prices, ask about setup fees. CIENCE charges one of unlisted size, while SalesHive says it has none.
Outsourced SDR vs cold email agency vs in-house SDR
- Outsourced SDR company: dedicated reps who call, email and use LinkedIn on your behalf. You get human conversations and objection handling, at per-seat prices like those above.
- Cold email agency: runs email-led campaigns, sometimes with an AI SDR layer. There is usually no phone work, it typically costs less per month, and it suits markets where buyers answer email more readily than calls.
- In-house SDR: you pay salary, commission, benefits, data and tooling, plus the time spent hiring, ramping and managing. You keep full control and all the learning. We have not put a number on this because cost varies by market. Calculators from memoryBlue and Abstrakt let you enter your own figures.
What does SDR-as-a-service include?
Across the ten companies, the common parts are list building and data research, messaging and copy, outreach by phone, email and LinkedIn, meeting booking, CRM logging and regular reporting. What varies is whether the rep is dedicated to you (SalesRoads, Callbox pods), whether every plan includes both calling and email (SalesHive Starter is phone only; Belkins Small business has no calling), how often you get reports (weekly at Callbox and Martal, monthly at CIENCE) and how fast it launches (under 14 days at CIENCE, 15 business days at SalesRoads, 45 days guaranteed at Sales Focus).

Comfortably worth it on these numbers.
Digital Patron's plans start at $800 a month. Every other number here is your own assumption; we don't publish meeting counts or guarantees. All plans are on the pricing page.
Red flags: guarantees and lock-ins
- Guarantees with no definition. A meeting guarantee is only useful if "qualified" is defined in writing. Abstrakt agrees its number in writing. Leadium guarantees activity, not outcomes. SalesHive guarantees no meeting count.
- Long pilots before you can leave. Martal's 3 and 4-month pilots are stated openly. Ask every vendor whose term is not stated (Callbox, Abstrakt, Belkins, memoryBlue, Sales Focus) for the exact length before signing.
- Setup and data fees outside the headline price.
- Who owns the domains, mailboxes and lists when the contract ends.

FAQ
What does an outsourced SDR cost in 2026?
Among the four companies that publish prices (checked 3 Nov 2026), CIENCE charges from $1,750 per offshore SDR a month plus a $2,000 campaign team fee. Abstrakt starts at $5,000 a month, a Callbox pod with one SDR costs $6,667 a month, and SalesRoads charges $11,950 per four weeks for one SDR. The other six quote on request.
Is SDR as a service worth it?
It is worth it when you need pipeline faster than you can hire and ramp a rep, and your buyers answer the phone. Published one-seat costs run from about $4,250 a month (CIENCE offshore, with fees) to $11,950 per four weeks (SalesRoads), so weigh that against the extra deals. Define a qualified meeting in writing before you sign.
Do outsourced SDR companies guarantee meetings?
Mostly not. Abstrakt agrees a number in writing and works free until it is hit by year end. Leadium guarantees activity, not outcomes. SalesHive says it guarantees no meeting count, and Sales Focus guarantees only a 45-day launch. The other six state no guarantee on the pages we checked.
What is the difference between an outsourced SDR and a cold email agency?
An outsourced SDR company provides reps who call, email and message prospects, usually priced per seat. A cold email agency runs email-led campaigns, often without phone work, and usually costs less per month.
What minimum term do outsourced SDR companies require?
CIENCE, Leadium and SalesHive state month-to-month terms, and SalesRoads says there is no long-term commitment. Martal runs a 3-month pilot, or 4 months on higher tiers. Callbox, Abstrakt, Belkins, memoryBlue and Sales Focus did not state a term on the pages we checked, so ask before signing.
