The real cost of cold outreach in 2026

Most companies undercount what outreach actually costs them. The SaaS subscriptions show up on the credit card statement. The SDR salary is on the payroll. The management time, the email infrastructure, the tooling fragmentation, and the opportunity cost of slow ramp rarely make it onto the same spreadsheet.

Here's a complete breakdown of what outbound actually costs in 2026, and what the comparison with an AI-powered alternative looks like.

The tools

A standard outbound stack typically includes:

• Data source (Apollo, ZoomInfo, Cognism): £79-£400 per month depending on data quality and volume. Apollo's basic plan is usable; ZoomInfo pricing starts at several hundred pounds per month for meaningful access.
• Email sending platform (Instantly, Smartlead): £79-£150 per month. This covers campaign management and basic deliverability.
• Enrichment/sequencing (Clay): £149-£350 per month if you're building complex workflows.
• CRM integration: If you're using Salesforce or HubSpot at any meaningful tier, add £50-£300 per month.

A lean stack runs £250-£400 per month. A full stack with decent data is £600-£900 per month. Call it £5,000-£10,000 per year in tools alone.

Email infrastructure

Cold email requires dedicated sending domains - you don't risk your primary domain on outreach. Standard practice is to register several subdomains (outreach.yourcompany.com, hello.yourcompany.com), set up Google Workspace or Outlook accounts on each, run a warmup period, then rotate sending across them.

• Domain registration: £12-£15 per domain per year
• Google Workspace: £5 per mailbox per month (you'll want 4-6 mailboxes minimum for decent volume)
• Setup time: 2-3 hours initially, then ongoing maintenance

Infrastructure costs run £400-£700 per year. Modest, but real.

The SDR salary

This is the largest line item for any outbound programme with a human at the centre.

A UK SDR with 1-2 years' experience earns £28,000-£35,000 in base salary. With a 50% OTE structure, on-target earnings sit around £42,000-£52,000. Add employer National Insurance contributions (13.8% on anything above £9,100), pension auto-enrolment (5% minimum), and you're at a true employment cost of £38,000-£48,000 per year before the person earns a penny in commission.

If they hit their targets and earn commission, total cost rises to £52,000-£65,000. Most SDRs are somewhere between 70% and 110% of target in any given quarter.

Realistic annual cost: £55,000-£65,000 including all-in compensation and employer costs.

Management overhead

Someone has to manage the SDR. Review sequences, coach on calls, handle escalations, run pipeline reviews. At a minimum, this takes 2-4 hours per week from a senior person whose time costs £50-£100 per hour depending on their seniority.

At 3 hours per week, 48 working weeks: that's 144 hours of management time. At £60/hr average cost, that's £8,640 per year. Not nothing.

Ramp time

New SDRs take 3-6 months to reach consistent productivity. During that period, you're paying full employment cost for 40-70% of the output. On a £60,000 total cost, a four-month ramp at 50% productivity costs you an extra £10,000 in effective salary-per-result.

Then there's churn. If your SDR leaves after 18 months, you eat recruitment costs (£3,000-£8,000 for a recruiter fee) plus another ramp cycle. The average cost of replacing an SDR is often cited at 30-50% of annual salary.

Total cost of one outbound function

• SDR employment cost: £58,000
• Tools: £7,000
• Infrastructure: £600
• Management time: £9,000
• Amortised ramp and recruitment: £8,000
• Total: ~£82,600 per year

For a well-run SDR, you might expect 6-10 qualified meetings booked per month. At 8 meetings per month, that's 96 per year, at a cost per meeting of around £860. At 6 meetings, cost per meeting rises to £1,150.

The AI-powered alternative

An AI outreach system - covering prospect research, email sequence generation, and voice follow-up - costs from £24.50 to £449 per month depending on volume tier (Starter is 50% off during beta, usually £49). Add the same email infrastructure (£600/year) and you're at £1,200-£5,988 per year in total spend.

The human element doesn't disappear - someone still needs to review outputs, approve campaigns, and handle the sales calls. But at 30-60 minutes per day rather than a full-time hire, the cost is a fraction.

If that system generates 4-8 meetings per month (achievable with the right ICP and content quality), cost per meeting drops to £125-£350.

The comparison isn't whether AI outreach is perfect. It's whether the ROI justifies the difference in investment, and by almost any reasonable calculation, it does.
