How I evaluate AI SDR vendors
I'm the office administrator for a 150-person company. I manage roughly 60-80 vendor orders a year, report to operations and finance, and I get pulled into software evaluations when a department can't agree on what to buy. So when our sales team asked me to help evaluate AI SDR platforms, I did what I always do: I compared the shortlisted vendors the way I compare suppliers, not by the headline price, but by what the contract really costs in time, maintenance, and risk.
The comparison that kept coming up was Artisan AI vs. 11x. Both are credible AI sales software companies. Both can run outbound campaigns. But they make different tradeoffs, and those tradeoffs matter more than the AI demo.
Here's the thing: the AI SDR part is becoming table stakes. The real differentiation is data, email verification, and CRM integration.
In this comparison, I'll use the same evaluation dimensions I used with our team: contact data platform, email verifier features (including API email validation), CRM integration depth, and pricing structure.
Dimension 1: Contact data platform vs. bring-your-own list
It's tempting to think all B2B contact data platforms are the same. They're not. The size of the database matters less than how fresh it is and how well it matches your ideal customer profile.
People assume a bigger database creates better outreach. In practice, better verification and enrichment create better outreach. A larger database just gives you more records to clean.
According to the Data & Marketing Association's Email Tracking Report (2018), email lists can decay by about 22.5% per year. That means a list bought in January is already leaking by the spring. For an AI SDR, that decay is dangerous because a bad email address doesn't just bounce; it damages sender reputation.
In our evaluation, this was the biggest difference between Artisan AI and 11x. Artisan positions itself as an all-in-one platform with its own 300M+ contact database, native enrichment, and email verification built into the same workflow. Its AI SDR, Ava, can pull contacts from that database and immediately verify them before outreach. According to Artisan's product docs (accessed April 2026), the database has 300M+ B2B contacts.
11x, on the other hand, is more of an AI sales execution platform. We looked at it as the brain, not the database. If your sales stack already includes a preferred contact data provider and email verification API, 11x can fit into that stack. During our evaluation, that distinction kept coming up: do you want one vendor accountable for the data and the AI, or do you want to assemble the layers yourself?
Put another way: Artisan bundles the pipeline; 11x assumes you can build the pipeline around it. Neither is wrong. But if you ask who is responsible when a lead turns out to be bad, the answer is much simpler with an integrated platform.
Conclusion: If you want one accountable vendor for data, verification, and outreach, Artisan AI is the more integrated choice. If you already trust your data stack and only need AI outreach, 11x is a legitimate option.
Dimension 2: Email verifier features and API email validation
This was the dimension where I changed my mind. Before our evaluation, I thought email verification was a checkbox: you upload a CSV, the tool removes bad addresses, done. That's the oversimplification. What I learned is that there are layers of verification, and the layer you need depends on how leads enter your system.
Here are the email verifier features I now look for:
- Syntax and domain/MX record checks
- Mailbox-level verification, including catch-all detection
- Role account detection (info@, sales@, admin@)
- Disposable and temporary address detection
- Spam trap and honeypot address detection
Artisan includes these verifier features natively. In our proof of concept, it flagged a handful of role-based addresses from the 300M database before our SDRs even drafted an email. That saved us from a deliverability hit before we started.
Now, the part that matters for B2B sales teams: what is API email validation and when should you use it? API email validation checks an address in real time when it enters your system, rather than in a periodic batch. It's triggered programmatically—by a form submission, a CRM API call, or a new lead from a LinkedIn integration. Each address gets verified before a human is involved.
A B2B sales team should use API email validation when leads come from multiple sources, when you don't have time to clean lists before an AI SDR starts outreach, and when a bad address would cause a sequence to stop. For example, if a webinar registration contains a typo, API validation can autocorrect or flag it before the address goes into the SDR's outreach sequence.
We tested both batch verification and API validation during our evaluation. Artisan's native verifier handled the standard batch cases, and its API-level checks caught the edge cases—disposable domains and catch-all servers—that a simple syntax check misses. You don't necessarily need a separate API verification service if the platform you choose already has one built in. Oh, and I should add one thing: API validation is not just for tech teams. If your AI SDR is going to run without constant oversight, real-time validation is how you keep the pipeline clean.
Conclusion: Native email verifier features are sufficient for steady-state outbound. API email validation is required when leads can enter the system without a human checking them. An all-in-one AI SDR platform with native API validation reduces both cost and admin burden.
Dimension 3: CRM integration depth and admin burden
When I compare software, I always ask how much work it will create for my team. A tool can look great in a demo and then create a nightly CSV upload problem in the real world.
We are a HubSpot shop. Both Artisan AI and 11x offer CRM integrations. The difference we found was depth. Artisan's native HubSpot/Salesforce integration goes beyond simple sync: it creates contacts, updates enrichment, logs email activity, and sends verified data back to the CRM automatically. That matters because the AI SDR isn't just sending emails; it's building a database your sales team can trust.
During our 2024 vendor consolidation project, we cut from fourteen sales tools to six. The lesson stuck with me: every new tool has an admin cost. Native integrations reduce that cost; shallow integrations just move it to the sales operations team.
Looking back, I should have asked about API rate limits before testing. At the time, I assumed “API” meant “unlimited.” It doesn't. If you plan to validate 5,000 contacts per day, you need to know the quota, not just the per-credit price.
11x has solid integrations too, and for a bigger team that can manage automation workflows, that's fine. But as an admin buyer, I care about who answers when sync breaks. With an integrated platform, there's one vendor to call. With a stack of point solutions, there's a blame game.
Conclusion: The depth of CRM integration determines whether an AI SDR saves your team time or creates more admin work. Artisan's native integrations make it easier for a small-to-mid-size team; 11x may work better for teams with dedicated sales ops.
Dimension 4: Pricing transparency and hidden costs
I don't publish vendor pricing because it changes and it's always contract-dependent. But I can share what I learned from the quotes we received around October 2025: the monthly per-seat prices for both Artisan AI and 11x were in the same general range. The real gap was in what the subscription included.
Artisan's pricing covered the AI SDR, the 300M-contact B2B database, the email verifier, and the CRM integration in one agreement. The 11x quote we saw was also a per-seat platform price, but several items we considered core—contact data, verification credits, or additional API calls—were treated as add-ons.
I'm not naming that to criticize 11x; every vendor has a reason to separate platform from usage. But if you're a finance-facing buyer like me, ask for the total annual contract value, not the per-seat rate. Ask which email verifier features are included, whether API validation counts against a credit limit, and what happens if you exceed your monthly contact imports.
If I could redo that decision, I'd ask for API usage logs before negotiating. But given what we knew then, assuming both quotes were comparable was reasonable. They weren't.
Conclusion: Compare what's included, not the headline rate. The cheapest-looking AI SDR quote can become the most expensive once data, verification, and API usage are added.
Which should your sales team choose?
If you already run a sophisticated sales stack with a preferred B2B contact data platform, a separate email verification API, and a dedicated sales ops person, 11x is a credible choice. It lets you keep the components you trust and focus on AI-authored outreach.
If you want fewer tools, one contract, and an AI SDR company that handles lead generation, contact data, email verification, and CRM integration together, Artisan AI is the stronger fit. Its 300M-contact database and native verifier features are designed for teams that don't have the time to manage six different sales tools. And because the verification is built into the platform, you get the API-level checks you need without another integration to maintain.
The fundamentals haven't changed: bad data before outreach means bad results after outreach. What has changed is execution. In 2021, best practice was to buy a list, batch-verify it, and send a sequence. In 2026, an AI SDR needs data that is verified at the moment of contact, integrated with the CRM, and connected to a feedback loop that improves the list over time.
So glad we tested with our real CRM data before committing to a full rollout. We almost signed the first vendor without checking API limits and role-account filtering. The 30-day proof of concept saved us from an expensive mistake.
Whichever platform you choose, run a small pilot with your own contacts. Ask the vendor to show you not just the AI demo, but the email verifier features, the API validation workflow, and the CRM integration. That's where the real difference is.
