Outsourced SDR Services
Updated: 5 October 2026
Newlead's outsourced SDR service runs the prospecting side of a sales development rep's job by cold email for B2B companies. We build and verify the list, write and send emails, follow up, handle and qualify replies, and deliver each interested lead to your Slack with name, company, email and phone number. No hiring, ramp or turnover. No cold calling.
Your sales team gets interested leads to call and close, without recruiting, ramping or replacing an SDR.

Copy and testing
Emails written for your audience, with several variants tested against each other.
Reply handling
Our team handles the replies and picks out the prospects who are interested.
Leads in your Slack
Each interested lead arrives with name, company, email and phone number. Meeting booking is an optional add-on.
How it works
Define your market
We agree on the target market, the ideal customer profile and the job titles to reach.
Build and verify the list
We find the decision-makers, verify their work emails and add phone numbers where available.
Warm up sending domains
Dedicated domains and inboxes, separate from your main domain, warm up for 14 days before the first emails go out.
Write and test the copy
We write the sequence for your audience and test several variants against each other.
Run the sequence
In a typical setup, each prospect gets 4 plain-text emails over about three weeks, at about 4 emails per inbox per day.
Handle replies, deliver leads
Our team handles the replies and sends each interested lead to your Slack with name, company, email and phone number.
What results look like
Results depend on your market, your offer and the size of your list.
In our own outbound, the campaigns we run to win clients for Newlead, we sent 371,590 emails to 143,319 decision-makers across 24 campaigns. The reply rate was 1.89%, counting human replies only, and the bounce rate was 0.62%. It took 202 contacted leads to create one opportunity, meaning a reply positive enough to log as a live sales conversation.
Market changes the math. The opportunity rate was 1.46% in Sweden, 0.97% in the UK and 0.31% in the US. Copy matters too: two versions of the first email in the same campaign got 0.67% and 0.25% reply rates, a 2.6x difference.
These are Newlead's own campaigns, not client results. Full data and definitions are in our cold email benchmarks 2026.
Which parts of the SDR job does Newlead take over?
A sales development rep (SDR) finds new buyers and opens conversations so account executives can close. The median SDR logs 112 activities a day: 44 calls, 41 emails, 19 LinkedIn touches and 8 other, according to Bridge Group's 2025 SDR research. We take over the email side end to end. We don't make calls or send LinkedIn messages.

What does an in-house SDR cost, and what are the risks?
Public figures, with the year each one covers:
| Figure | Value | Source |
|---|---|---|
| Median SDR on-target earnings | $80,000 a year ($55,000 base, $25,000 variable) | Bridge Group, 2025 |
| Wages and paid leave as a share of employer cost, US private industry | 77.5% (wages 70.0%, paid leave 7.5%) | BLS, June 2026 |
| Time to ramp a new SDR | 3.0 months | Bridge Group, 2025 |
| Average SDR tenure | 1.9 years | Bridge Group, 2025 |
| Median yearly attrition | 40% | Bridge Group, 2025 |
| Reps at quota | 60% | Bridge Group, 2025 |
| Average SDR pay, UK | £39,774 a year | Glassdoor UK, 2026 |
| Employer National Insurance, UK | 15% on pay above £5,000 a year, before any Employment Allowance | GOV.UK, 2026 to 2027 |
Figures last checked 3 October 2026. Bridge Group surveyed 351 B2B companies, 78% in North America and 83% in B2B SaaS.
Our rough estimate: wages and paid leave are 77.5% of employer cost, and a salary already covers paid leave. So $80,000 in on-target earnings means about $103,000 a year, or $8,600 a month, before tools, data, recruiting and management. The 3.0-month ramp is about 13% of a 1.9-year average tenure.
The bigger cost is risk. You pay through the ramp, the median team loses 40% of its reps a year, and only 60% of reps hit quota. Outsourcing moves hiring, ramp and turnover to the provider. You still carry the fee, your team's time on the leads and the chance that your market doesn't respond.
The full side-by-side numbers are in outsourced SDR vs in-house SDR cost. For the broader build-or-buy question, see in-house vs agency lead generation.
When is an in-house SDR the better choice?
An in-house rep usually wins when:
- The phone is your best channel. If calls drive your pipeline, hire someone who dials. We don't.
- Your product is complex or high-value. In a 2023 SaaStr survey of 1,200+ respondents, only 7% had really gotten outsourced SDRs to work and 26% said it sort of worked. Comments said complex, high-value products need product knowledge from the first conversation, and that outsourcing did better in a specialized market or a new region.
- You sell to a short list of large enterprises. When we emailed US enterprises to sell our own service, it took 2,500+ contacted leads per opportunity, and our benchmark report recommends a different channel for that segment.
- You want to build a sales bench. The SDR seat is a common training ground for future account executives.
Or split the job: keep a rep on calls and key accounts, and let us run email prospecting, with leads landing in Slack for your rep to call.
AI SDR tools or a managed team: what is the difference?
AI SDR tools write and send outreach for you. They are software, so someone on your side still owns the targeting, the list quality, your domains, what goes out and the replies.
A managed team takes those jobs off your plate: we define the market with you, verify the list, send from dedicated domains, test the copy and handle the replies. You get interested leads in Slack, not another tool to run.
The trade-off is control. A tool gives you full control and full responsibility. A managed team gives you less hands-on control and one team accountable for the work.
How does Newlead compare with other SDR agencies, LinkedIn and ads?
- Other SDR agencies. Many sell booked meetings from teams that call, email and use LinkedIn. We run email only, deliver interested leads first and publish our typical setup: 4-6 sending domains and 100-250 inboxes.
- LinkedIn. It can work for a few senior contacts, but we don't run it. See cold email vs LinkedIn outreach.
- Paid ads. Search ads catch buyers who are already looking. Cold email reaches named buyers who are not. See cold email vs paid ads.
What this costs
We don't publish prices. The cost depends on your market, the volume you need and the setup, so we scope it on the discovery call.
Market is who you sell to and where. Volume is how many decision-makers we need to reach. Setup is how many domains and inboxes that takes at low volume per inbox. Meeting booking is an optional add-on.
For market price ranges with sources, see what B2B lead generation costs. To weigh the fee against a hire, see outsourced SDR vs in-house SDR cost.
Who this is for
- B2B companies selling to a clear group of decision-makers in the US, UK, Canada or Europe
- Sales teams with room for more conversations but no time to prospect
- Founders and sales leaders who want outbound without hiring an SDR
- Firms in markets we know, like accounting and CPA, fractional CFO, wealth management, SaaS, law and consulting
- Teams that may want to own the system later, through our one-time implementation
Who this is not for
- Phone-first teams that want someone to make cold calls
- Companies that need LinkedIn, events or multichannel SDR work
- Enterprise sellers working a short list of large accounts
- Complex, high-value products where the first conversation needs deep product knowledge
Common questions
What are outsourced SDR services?
Outsourced SDR services, also called SDR as a service, put an outside team on the prospecting work of a sales development rep: finding the right buyers, contacting them, following up and passing interested prospects to your sales team. Newlead runs the email side only and delivers each interested lead to your Slack with name, company, email and phone number.
Do you make cold calls or send LinkedIn messages?
No. We run the email side of prospecting only. Each interested lead arrives in your Slack with a phone number, so your team can call while the interest is fresh. If the phone is your best channel, an in-house SDR or a calling agency will fit better.
How many meetings or leads will we get?
It depends on your market, your offer and how many decision-makers fit your profile. What we control is the work: the list, the sending setup, the copy, the testing and the reply handling. On the discovery call we run the numbers for your market and tell you what is realistic.
Can you book meetings into our calendar instead?
Yes, as an optional add-on. By default we deliver each interested lead to your Slack with name, company, email and phone number, and your team takes it from there. If you would rather have meetings booked into your calendar, we add that on top of lead delivery.
How long does it take to get started?
Plan for 14 days before the first emails go out, because new sending domains need to warm up first. Each prospect then typically gets 4 emails over about three weeks, and replies come in from the first email onward. An in-house hire is slower: Bridge Group's 2025 research puts SDR ramp at 3.0 months, counted after the hire.
Do we keep the leads, and can we own the system?
Yes. Every interested lead is delivered to your own Slack. The ongoing service sends from dedicated domains and inboxes, separate from your main domain, so your main domain is not used for cold email. To own the system itself, choose our one-time implementation: we build the outbound system and you own it.
