Twelve questions to ask an outsourced SDR provider, and the answers that should worry you

Key takeaways

  • The best questions to ask an outsourced SDR company are about things you can check: who does the work, which domains send your email, who owns the data, and how meetings are counted.
  • A good answer to a due diligence question names a person, a number or a document you can see, and a weak answer relies on adjectives such as "proven" or "best in class".
  • Ask where your email will be sent from, because Google expects bulk senders to authenticate with SPF, DKIM and DMARC and to keep spam rates below 0.3 percent.
  • Ask what happens if it does not work before you sign, since the exit terms show how much risk the provider is willing to share.
  • Any provider that promises a fixed number of meetings is promising something nobody controls, so treat it as a reason to ask more questions, not fewer.

Questions to ask an outsourced SDR company before you sign

The questions to ask an outsourced SDR company fall into five groups: who does the work, how email and calls are sent, who owns the data, how results are counted, and how you can leave. Ask each one in a call and keep the written answer, because an answer you cannot check later is only a sales line.

This is the step before signing with a provider and before onboarding. It is written for a founder or sales leader at a technology company who is comparing two or three providers.

What the published question lists cover, and what they skip

We read two vendor guides in full. Belkins, an outbound agency, publishes a list of 21 exploratory questions. Business Age, a trade news site, published an article on what to know before hiring an outsourced SDR agency. Both are vendor or sponsored views, so treat their advice as a checklist and not as neutral research.

  • Belkins focuses on conversation quality: how scripted the messages are, how the team sets expectations, how it handles feedback, what safety nets exist if a campaign slows down, and how it keeps prospects from ghosting. It also says some teams offer extended unpaid support when a slow start misses the agreed deliverables, and calls cookie-cutter offers that promise the same results to everyone a red flag.
  • Business Age focuses on fit: industry understanding, B2B specialism, whether SDRs are dedicated or shared across clients, who will work on your account and how performance is measured.

Those are fair questions, and they are mostly questions about how a provider talks. Neither guide asks where your email is sent from, who owns the list when you leave, or how a meeting is defined and counted. Those are the questions you can verify, and they are where disputes start. The rest of this post adds them.

Group one: who actually does the work

  1. Who will be my named SDR, and how many other accounts will they work at the same time? Business Age says to find out who works on your account and how much time they give it. A good answer is a name and a number. A weak answer is "a dedicated team" with no cap.
  2. What happens if the rep leaves or underperforms? Ask who replaces them, how long a new rep takes to ramp, and who pays for that time. A good answer commits to a replacement process in writing.
  3. Can I speak with the person who will write my messages, not only the person selling to me? The sales call shows the seller, not the delivery team. A weak answer is that you will meet the team after signing.

Group two: how email is sent, the question most lists skip

Your company name sits on every message a provider sends, and the sending setup decides whether those messages reach an inbox. Google publishes its email sender guidelines. For senders of more than 5,000 messages a day to Gmail accounts, they require SPF, DKIM and DMARC authentication, one-click unsubscribe for marketing and subscribed messages, and a spam rate below 0.3 percent in Postmaster Tools. Ask the provider how it meets that, in plain terms. For more detail see cold email deliverability in 2026.

  1. Which domains will send my outreach? A good answer is separate sending domains, so volume never touches your main company domain. A worrying answer is that they will send from your primary domain to save setup time.
  2. Who sets up and monitors SPF, DKIM and DMARC, and can I see the result? A good answer names the person, the checks and how often they run.
  3. How do you keep spam complaints low, and will you share the number? A good answer cites a monitoring tool such as Postmaster Tools and a threshold. A weak answer is "our emails are always personalized".

Two ways a provider can answer the same question

An answer you cannot check

  • "We have years of experience with deliverability."
  • "Our team handles all of that for you."
  • "We never have problems with spam."
  • Nothing you can look at, test or put in a contract.

An answer you can check

  • Outreach goes out from separate domains, not your main one.
  • SPF, DKIM and DMARC are set up and you can look at the records.
  • Spam rate is watched against Google's 0.3 percent limit and shared on request.
  • Volume is raised gradually after a soft launch, not on day one.
The example question is "How do you protect my domain and reputation?" Both columns are illustrations written for this post, not quotes from any provider.

Group three: data, tools and who owns what

  1. Who owns the prospect list, the replies and the verification status, and can I export them at any time? A good answer is that you own it all and can export it on request. A weak answer is that the data lives in the provider's tools and is theirs.
  2. Will the provider work inside my CRM, or report from its own spreadsheet? Business Age lists CRM integration as part of a normal SDR stack. If meetings are tracked only in tools you cannot see, you cannot audit them.

Group four: how results are defined and counted

  1. How do you define a qualified meeting, and who decides? A good answer is a written definition you approve. This is the single most useful contract line, as covered in how to measure outsourced SDR performance.
  2. What do you report weekly and monthly, and does it include held and accepted meetings, not only booked ones? A good answer separates booked, held and accepted. A weak answer reports emails sent and replies.
  3. How do you set expectations before a campaign starts? Belkins asks this too. A good answer discusses your market, your sales cycle and uncertainty. A worrying answer is a fixed number of meetings promised for everyone.

Group five: what it costs to leave

  1. What happens if this does not work? Belkins calls out the importance of a safety net. A good answer describes a concrete remedy, such as a review point, a rep replacement or a clean exit. A weak answer is that it always works.
  2. What is the minimum term, the notice period and the exit process? Ask about setup fees, auto renewal and what you take with you: data, domains and documentation. For how pricing is structured, see outsourced SDR cost.

How to use the answers to compare providers

  1. Ask all twelve in writingSend the same list to each provider and ask for written answers. It is easier to compare text than memory of a call.

  2. Mark each answer checkable or notA checkable answer names a person, a number, a setting or a document. An uncheckable one uses adjectives only.

  3. Verify two answers yourselfLook up the sending domains and the authentication records, and ask for a reference at a similar company. Check what you were told.

  4. Put the answers in the contractAnything that mattered to your decision, such as domain use, data ownership and the qualifying definition, becomes a written term.

Every step passesMost answers are checkable and two held up when you verified them. Move to a pilot with the answers written into the agreement.

Any step failsSeveral answers are vague or one failed a check. Treat that as the result of the call and compare another provider.

A working method built from the question groups above. It is a process for you, not an industry standard.

Checklist for the provider call

  1. Send the twelve questions before the call and ask for a written reply.
  2. Ask for the name of the rep and the maximum number of accounts they work at once.
  3. Ask which domains send your outreach and look up the authentication records yourself.
  4. Ask who owns the data and request the export format in writing.
  5. Write your definition of a qualified meeting first, and ask whether they accept it.
  6. Ask to see a sample weekly report with held and accepted meetings.
  7. Ask for the notice period, the renewal terms and what happens to your data on exit.
  8. Treat any guaranteed number of meetings as a red flag and ask what they would do if it were missed.
  9. Ask for one reference at a company that sells something like yours, and call it.

What no question can tell you

Good answers lower the risk. They do not remove it. No provider controls whether a prospect has budget this quarter, and none can promise meetings, pipeline or revenue. A short pilot with agreed measures, a written definition and an exit you can live with is the way to find out, because it tests the provider and your own sales process together.

Our outsourced SDR reps work a maximum of three accounts each, from separate warmed sending domains, for a flat monthly fee per rep with no per-meeting surcharge. We would answer these twelve questions in writing for you. If you are still deciding whether to outsource at all, the in-house vs outsourced SDR comparison is a good place to start.

Questions

What should I ask an outsourced SDR company before hiring?

Ask who will do the work, which domains send your email, who owns the data, how a qualified meeting is defined and counted, and what the exit terms are. Prefer questions whose answers you can check yourself.

What are red flags when choosing an outsourced SDR agency?

A guaranteed number of meetings, sending from your main company domain, no named rep, data kept only in the provider's tools, and vague answers about exit terms are all reasons to look harder or walk away.

Should an outsourced SDR provider send from my main domain?

It is safer to send cold outreach from separate sending domains, so a deliverability problem does not affect your company email. Ask the provider where it will send from and have them show you the authentication records.

Who should own the prospect data in an outsourced SDR contract?

You should, with the right to export the list, replies and verification status at any time. Write this into the contract before launch so the data goes with you if the contract ends.
