How to Evaluate an Outsourced SDR Provider: 10 Questions to Ask Before Signing

The Outsourced SDR Market Is Crowded — And Quality Varies Wildly

There are hundreds of outsourced SDR providers, and they range from exceptional partners who genuinely accelerate pipeline to glorified spam shops that burn through your TAM and damage your brand. The difference often isn't visible in their pitch deck. You need to dig deeper.

Question 1: What's Your Rep Turnover Rate?

If they hesitate or won't give you a number, that's your answer. High turnover means your account is constantly being handed off to new reps who don't know your product, your market, or your prospects' pain points. Look for providers with annual turnover below 30% — and ask to meet the specific reps who'll work your account.

Question 2: How Do You Train Reps on Our Product?

A good provider has a structured onboarding process that includes product training, ICP deep-dives, competitive landscape review, and messaging workshop. They should be able to show you their training curriculum and timeline. If their answer is "we'll do a one-hour kickoff call and you'll send us some materials," move on.

Question 3: Can I Listen to Calls and Review Emails?

Full transparency is non-negotiable. You should have access to call recordings, email sequences, and LinkedIn messaging at all times. If a provider pushes back on this, they're hiding something — usually low-quality outreach that doesn't represent your brand well.

Question 4: What Does Your QA Process Look Like?

The best providers have dedicated QA managers who review calls and emails weekly, provide coaching, and maintain brand consistency. Ask how they handle messaging drift, underperformance, and quality issues. A mature QA process is often the single biggest differentiator between good and great providers.

Question 5: How Do You Define a Qualified Meeting?

This is where misalignment happens most. If their definition of a "qualified meeting" is "anyone who agrees to a call," you'll drown in bad meetings that waste your AEs' time. Define qualification criteria upfront — ICP fit, authority level, identified pain, timeline — and make sure the provider's compensation structure incentivizes quality over volume.

Questions 6-10: The Details That Matter

Ask about data sourcing (where do they get contact information, and how fresh is it), technology stack (what tools do they use for sequencing, dialers, and intent data), contract flexibility (can you scale up or down with 30 days' notice), reporting cadence (weekly dashboards and monthly business reviews at minimum), and reference accounts (ask to speak with current clients in similar industries or deal sizes).

The Bottom Line

The right outsourced SDR partner should feel like an extension of your team within 60 days. If they can't answer these questions confidently and specifically, they're probably selling a service they can't consistently deliver.
