If you've been in outbound long enough, you already know this:

AI didn’t replace SDRs; it just replaced the boring parts of outbound.

Tools like 11x AI became popular fast because they promised something every founder wants: a predictable pipeline without hiring a full SDR team.

And honestly, for early-stage GTM or lean teams, it does a decent job. It researches, writes, and sends for you. It books meetings.

But as soon as you try to scale outbound beyond the “send emails and pray” stage, reality hits:

• Your ICP gets more specific
  
  

• Personalization matters more
  
  

• Deliverability becomes a real problem
  
  

• Data quality starts shaping your conversion rate
  
  

• You need context, judgment, and messaging clarity — not just automation

That's when founders realize a simple truth:

Outbound isn’t about sending more messages. 

It’s about sending the right messages to the right people, at the right time.

AI can help with speed. But you still need:

• A solid GTM hypothesis
  
  

• A compelling offer
  
  

• ICP clarity beyond “B2B companies”
  
  

• Human oversight to redirect when messaging misses
  
  

• Tools that protect inboxing and data quality

And that’s why many teams start with 11x, then look for alternatives that give them:

• More control
  
  

• Better personalization
  
  

• Stronger deliverability
  
  

• Better intent signals
  
  

• Real GTM flexibility instead of a “black box”

In this guide, I’ll break down the 7 best 11x AI alternatives that can help you scale meetings without burning your domain, your brand, or your budget.

- You’ll find tools here that plug into a modern outbound stack, not replace it.

Let’s get into it.

7 Best 11x ai. Alternatives 

1. Stamina.io – Best if you're focused on deliverability and want full control over domains, pacing, and GTM strategy.
   
   

2. AiSDR – Best if you want a fully done-for-you outbound system with domains, warmup, rotation, and GTM support handled end-to-end.
   
   

3. MeetChase AI SDR – Best if you prefer a performance-based model and only want to pay when meetings happen.
   
   

4. Coldreach.ai – Best if you want signal-based outbound triggered by real buying intent.
   
   

5. Artisan AI – Best if you want an all-in-one AI SDR suite with built-in data, warmup, dynamic limits, and deep personalization.
   
   

6. Agent Frank (Salesforge) – Best if you want automation plus control, with AI that can run hands-free or let you approve messaging.
   
   

7. Jason AI by Reply.io – Best if you’re scaling multichannel (email + LinkedIn + calls + SMS) inside an established sales stack.
   
   

Comparison Criteria (What Actually Matters When Choosing an AI SDR)

When you evaluate 11x AI alternatives, it’s easy to get distracted by features and AI buzzwords.

In practice, outbound only works when fundamentals are tight.

Here’s what really matters:

1) Deliverability & Infrastructure

If your emails don’t land in inboxes, nothing else matters.
Look for tools that support:

• Domain setup + warmup
  
  

• Inbox rotation / dynamic send limits
  
  

• Sender reputation monitoring
  
  

• Inbox placement testing (ideal but rare)

Rule: AI is useless if it burns domains.

2) Data Quality & Enrichment

Great outbound isn’t about volume, it's about relevance.
Key considerations:

• Verified B2B data coverage
  
  

• Built-in contact search vs bring-your-own-data
  
  

• Intent & trigger signals
  
  

• Accuracy and freshness

Cheap data = expensive pipeline.

3) Personalization Depth

There’s AI personalization… and then there's actual personalization.

Ask:

• Does it pull context (funding, job changes, tech stack, news)?
  
  

• Does the messaging adapt tone and angle per persona?
  
  

• Does it sound like a founder/rep, or like AI?

The market filters out generic AI emails fast.

4) Multi-Channel Execution

Modern outbound isn't email-only, it’s layered.

Evaluate:

• Email
  
  

• LinkedIn flows
  
  

• SMS/WhatsApp (optional)
  
  

• Calls/voicemail drops (for higher intent)
  
  

• Calendar routing & auto-pausing sequences

More channels = more trust and reply paths.

5) Workflow Flexibility & Control

Avoid black-box systems. You want visibility and override power.

You should control:

• ICP rules & filters
  
  

• Messaging approval (auto + human review options)
  
  

• Sending limits & pacing
  
  

• CRM syncing & reporting
  
  

• Deliverability guardrails

AI can run, but you need a steering wheel.

6) Support & GTM Guidance

Outbound isn’t “set and forget.”
Expect learning, tuning, iteration.

Best-in-class platforms provide:

• Real onboarding
  
  

• Slack support or strategy guidance
  
  

• Troubleshooting help
  
  

• Message testing recommendations

AI ≠ strategy. Tools that support GTM win in the long term.

7) Pricing & Scale Efficiency

Outbound is a compounding channel; costs scale fast.

Pay attention to:

• Cost per mailbox/contact / seat
  
  

• Pay-per-meeting vs software fee models
  
  

• Warmup included or separate?
  
  

• Volume caps/message quotas

Cheap tools are expensive if they don't convert.

11x AI vs. 7 Top Alternatives

1. Stamina.io -  Best for Deliverability-First, GTM-Controlled Outreach

If you're the type of founder or GTM leader who cares about the plumbing… domain health, inbox placement, pacing, and repeatable pipeline, Stamina is the safest alternative to 11x.ai.

Think of it as: 

Outbound infrastructure + AI SDR + CRM + workflow engine in one system. 

Instead of letting an AI “guess,” it gives you automation with guardrails.

In other words, it won’t let you accidentally burn domains, blast too early, or spray generic messaging. It forces quality. 

Why it’s a strong 11x alternative

11x is “hands-off and hope it works.” 

Stamina is “hands-off, but with visibility and control.”

You get:

• AI warmup across a large real inbox network
  
  

• Inbox-placement testing (rare in this category)
  
  

• Dynamic send throttling based on sender health
  
  

• Real-time alerts before anything goes wrong
  
  

• AI sequences built from live buying signals, not just “first name + company” merges
  
  

• Built-in CRM + email + LinkedIn + SMS + dialer + workflows

This is built for companies who want scale without gambling deliverability.

Who it's best for

• Founders serious about protecting domains
  
  

• Teams building an outbound engine (not a stunt)
  
  

• Agencies managing deliverability risk across accounts
  
  

• GTM leaders who want to own infrastructure, not outsource it to a black box

If you're thinking “I don’t just want meetings, I want consistent pipeline with clean sending reputation,” this is your pick.

Key edges

• Inbox placement reports = you know if you're landing or not
  
  

• AI BDR (Zara) writes from intent signals, not just templates
  
  

• CRM + sending + data layer unified, no syncing chaos
  
  

• Unlimited emails (not priced per inbox)
  
  

• You get go-to-market help on the Assisted plan, not just software

This is the closest thing to AI SDR + deliverability engineering in one place.

Trade-offs / watch-outs

Not a “turn on and pray” tool.

• Domain provisioning isn’t included (add-on)
  
  

• No instant blasting, controlled warm-up is intentional
  
  

• No public API yet (workflows cover most needs)
  
  

• Best value kicks in once you’re sending responsibly at scale, not for quick hacks

This is a platform for operators not founders who want magic buttons.

Pricing

Starts at $397/mo (Base) 

$797/mo includes hands-on GTM + Slack support

Unlimited emails included. 

Send volume tied to health, not seats or inbox count.

Summary

If 11x is autopilot, Stamina is autopilot with radar, co-pilot, and safety checks.

It’s built for companies who want:

• better inboxing
  
  

• more control
  
  

• scalable outbound
  
  

• and predictable revenue, not “AI roulette”

2. AiSDR - Best for Fully-Managed, Zero-Work AI SDR Setup

If you don’t want to touch domains, warm-up, inboxes, rotation, or campaign execution, AiSDR is the “done-for-you outbound team in a box.”

It’s not “AI that helps you run outbound.” It’s AI that runs outbound for you.

Think… SDR hire, deliverability engineer, data provider, and ops person bundled into one service.

Why it’s a strong 11x alternative

With 11x, you trade control for automation. With AiSDR, you trade control for automation + infrastructure + people behind it.

They handle:

• Domain purchase & DNS
  
  

• Mailbox setup
  
  

• Warm-up & rotation
  
  

• Sender verification
  
  

• Deliverability protection
  
  

• Data sourcing from 700M+ contacts
  
  

• Copywriting & sequences
  
  

• Outreach across email + LinkedIn + SMS
  
  

• Calendar routing & auto-pausing on booking
  
  

• Campaign optimization with a GTM engineer

If you don’t want to think about outbound mechanics at all, this one is hard to beat.

Who it’s best for

• Founders who don’t want to manage outreach
  
  

• Teams without SDRs or RevOps
  
  

• Agencies offering outbound but not ops
  
  

• Anyone who wants pipeline without building systems

This is “plug in and meetings start coming in”, ideal if you don’t want to learn deliverability, AI prompting, multi-inbox rotation, etc.

Key edges

• True concierge outreach
  
  

• Unlimited lead access (no Apollo bill)
  
  

• 24/7 support + private Slack
  
  

• Multichannel: email + LinkedIn + SMS + video/voice
  
  

• Outreach pauses the moment a meeting gets booked
  
  

• Warm-up and sending rotation built in

You pay a premium, but you’re buying execution, not just software.

Trade-offs / watch-outs

This is not for tinkerers.

• You're giving up control to a system + operator team
  
  

• Pricing is message-based, not seat-based, scaling costs can rise
  
  

• Ramp period still applies, they won’t blast from day one
  
  

• Shared messaging quota across email + LinkedIn can feel tight for volume outbound
  
  

• If you’re a heavy optimizer / want tight creative control, this isn’t your play

You’re outsourcing strategy + execution. If that scares you, skip it.

Pricing

Starts at $900/month 

Includes 1,200 AI-generated emails + LinkedIn touches (combined quota)

Unlimited leads included. Messaging budget is your real meter.

Summary

AiSDR is the closest thing to saying “hire an SDR & deliverability engineer, but automated.”

Choose it if you value outcome > control and don’t want to build an outbound engine internally.

3. MeetChase - Best for Pay-Per-Meeting, Low-Risk Outbound

MeetChase flips the outbound model: instead of paying for seats, inboxes, or message volume, you pay primarily when meetings happen.

If you're tired of paying for software + data + SDRs before results, this model feels refreshing.

Think of it as:

AI SDR + data + warm delivery system + pay-as-you-win model.

It’s built for founders who don’t want to gamble budget, you put in a small base fee, and only scale cost when real pipeline shows up. 

Why it's a strong 11x alternative

11x ai automates outreach inside its own system. 

MeetChase automates outreach and ties its economics to your success.

You get:

• AI prospect sourcing
  
  

• 600M+ verified contacts
  
  

• Native Google & Outlook sending
  
  

• Domain warmup + deliverability monitoring
  
  

• Automated outreach + scheduling
  
  

• Meetings booked directly on your calendar

The difference? You’re paying for results, not just activity.

Who it’s best for

• Founders who value capital efficiency
  
  

• Small GTM teams without SDRs
  
  

• Agencies wanting predictable COGS for client outbound
  
  

• Teams testing outbound before committing to large software spend

If you’re allergic to SaaS bills before pipeline, this model makes sense. 

Key edges

• Pay only when a meeting happens
  
  

• Email sending goes through your Google/Outlook, not a shared sending pool
  
  

• Sender-health monitored continuously
  
  

• Calendar sync auto-stops outreach once meeting is set
  
  

• AI handles targeting + writing + follow-ups

It’s built for performance accountability, not max sending volume. 

Trade-offs / watch-outs

This is not the tool for bulk testing or rapid blasting.

• Domains + inboxes purchased separately (small extra cost)
  
  

• Ramp-up period before volume, deliverability first
  
  

• No instant self-serve; onboarding required
  
  

• No open API, you operate in their box
  
  

• Per-meeting pricing can get expensive if you're scaling aggressively

This is a precision tool, not a spray tool.

Pricing

• $125/mo base
  
  

• $250 per meeting held, or
  
  

• 10% of first-year revenue + $125/mo

Pay-as-you-convert. If you're early-stage, this protects cash.

Summary

MeetChase is for founders who want “pay only when pipeline shows up.”

It prioritizes deliverability, quality, and outcomes — not blasting volume.

4. Coldreach.ai - Best for Signal-Based, Context-Driven Outbound

Coldreach monitors your ICP 24/7 for live buying signals - new funding, hiring bursts, tech-stack changes, press mentions, or leadership moves, and triggers personalized outreach automatically. Instead of cold lists, you get warm context.

Why it’s a strong 11x alternative

11x fires generic campaigns from a static list. 

Coldreach fires relevant campaigns from live intent.

You can:

• Define custom intent rules across 5+ public sources (news, job posts, filings, site updates, LinkedIn activity).
  
  

• Auto-generate messages around those signals so every touch feels timely.
  
  

• Sync with your tools - Salesforce, HubSpot, Salesloft, Apollo, Slack, or even custom API workflows.
  
  

• Keep your CRM fresh with weekly lead updates and exports.
  
  
  

Who it’s best for

• GTM teams that already have sending infrastructure.

• Founders who care more about timing than volume.

• Agencies building multi-client outbound where intent data is the edge.

• Operators who want to plug AI SDR logic into their own stack.
  
  
  

Key edges

• 79M+ companies tracked in real time.

• You define your own buying triggers.

• Outreach copy built around “why now,” not “who you are.”

• Deep native integrations for flexible workflows.

• API and custom-code options for builders.
  
  
  

Trade-offs / watch-outs

• Doesn’t manage domains or warm-up — you bring your own deliverability setup.

• Focuses mainly on email and LinkedIn (no SMS or calls).

• Sending controls like pacing and throttling rely on the connected tools, not Coldreach itself.
  
  

Summary

Coldreach is for teams who want to stop guessing and start acting on intent. 

It handles your infrastructure, but if you already have healthy domains and want precision targeting with real-time triggers, it’s one of the smartest upgrades from 11x.

5. Artisan - Best for All-in-One AI SDR + Personalization Suite

Artisan AI is built for teams that want everything in one system - data, deliverability, personalization, and outreach, without juggling multiple tools.

At its core is Ava, a virtual AI SDR. Ava researches prospects, writes messages, personalizes them in real time, sends them across email and LinkedIn, follows up, and keeps inboxes healthy automatically.

Why it’s a strong 11x alternative

11x gives you Alice and Julian AI SDRs, but lacks transparency or customization. 

Artisan does the same job but gives you control, data access, and deliverability visibility inside one platform.

You get:

• 300M+ verified B2B contacts

• Built-in warm-up and inbox health tracking

• Dynamic send limits that adjust per inbox

• Advanced personalization logic (tone, CTA, formality)

• CRM integrations with HubSpot and Salesforce

It’s not just about automation, it’s about staying human at scale.

Who it’s best for

• Teams that want a unified outbound suite, not multiple tools
  
  

• Founders who want AI SDRs with personalization and deliverability guardrails
  
  

• Companies using HubSpot or Salesforce as their CRM backbone
  
  

• SDR managers who need visibility into both copy and sending performance
  
  

If you’ve outgrown 11x’s black-box approach but still want AI running the heavy lifting, Artisan’s mix of personalization + deliverability balance is ideal.

Key edges

• Personalization Waterfall — every email sounds different, tested automatically for tone and CTA fit.
  
  

• Built-in Data Miner — pulls context from Crunchbase, BuiltWith, Twitter, StoreLeads, and LinkedIn.
  
  

• Autopilot deliverability — warm-up, placement tracking, and dynamic pacing built in.
  
  

• Multichannel reach — email + LinkedIn, tracked in one workspace.
  
  

• Native CRM sync — no manual exporting or CSV headaches.
  
  
  

Trade-offs / watch-outs

• Pricing is custom; you’ll need to contact sales.
  
  

• An all-in-one approach can replace parts of your stack instead of integrating.
  
  

• Limited manual override for inbox-level troubleshooting mid-campaign.
  
  

• Slower LinkedIn ramp due to native platform limits.
  
  

• CRM integrations are mainly optimized for HubSpot and Salesforce.
  
  
  

Summary

Artisan is for teams that want to scale outreach with personalization, not just volume. It automates the SDR workflow end-to-end while keeping tone, timing, and deliverability in check, ideal if you want sophistication without building the tech stack yourself.

6. Agent Frank (Salesforge) - Best for AI Outreach With Deliverability Built In

Agent Frank is the practical middle ground between “AI does everything” and “you control nothing.” 

It’s an AI SDR that can run on Auto-Pilot (full automation) or Co-Pilot (review-before-send) mode, so you choose how hands-on you want to be.

Alt-text: Salesforge - Best Alternative to 11x.ai

Backed by Salesforge’s deliverability stack, it comes with free unlimited Warmforge warm-up and optional full email infrastructure, giving you visibility into sending health as you scale.

Why it’s a strong 11x alternative

11x locks you into a closed system with little control over domains or compliance. 

Agent Frank gives you AI outreach + deliverability transparency + human approval in one setup.

You get:

• 500 M+ verified contacts searchable in-app

• Multi-channel outreach (email + LinkedIn)

• Unlimited inbox warm-up via Warmforge

• Slack access and dedicated GTM specialist

• Autopilot or Copilot workflows for any campaign size
  
  

Who it’s best for

• Founders who want automation but still need compliance and tone oversight

• GTM teams are prioritizing inbox placement and data quality

• Agencies running campaigns across multiple clients/domains

• Operators scaling responsibly, not recklessly
  
  

Key edges

• Auto-Pilot / Co-Pilot modes = automation with optional review

• Unlimited warm-up included (no extra subscription)

• Dedicated Slack support + GTM specialist for live tuning

• 500 M+ contact engine cuts third-party data costs

• Integrated LinkedIn + email flows with automatic hand-offs
  
  

Trade-offs / watch-outs

• Domains & mailboxes sold separately (add-on)

• Base plan supports up to 1,000 active contacts; extra usage adds cost

• No built-in dialer yet

• Set up via short demo call (not instant self-serve)

• Multi-channel pacing controls are not fully public yet
  
  

Pricing

• $499 / month

• $416 / month on an annual or quarterly plan.

Includes up to 1,000 active contacts; $0.25 per extra beyond 2,000

Summary

Agent Frank is for teams who want AI running outreach —but with the visibility, warm-up, and Slack support to keep it safe. 

It’s the most balanced upgrade from 11x if you care about inbox placement, tone control, and having a human in the loop.

7. Jason AI (Reply.io) - Best for Multichannel AI SDR at Scale

Jason AI is Reply.io’s enterprise-grade AI SDR built for teams that already run serious outbound and need automation across every channel: email, LinkedIn, calls, SMS, and even WhatsApp.

It generates and personalizes outreach sequences from your data inputs, handles replies, detects meeting intent, and books directly through Google Calendar. Under the hood sits a data engine of 1 billion contacts (including 220 million U.S. records), so you’re never short on targets.

Why it’s a strong 11x alternative

11x works well for lightweight automation but is limited to basic email-based flows. 

Jason AI, on the other hand, is multichannel, data-rich, and built for scale. 

You still get automation, but with enterprise-level deliverability, scheduling, and CRM control.

You get:

• Email + LinkedIn + calls + SMS + WhatsApp in one workspace

• Autopilot or Copilot mode (full automation vs. manual approval)

• Integrated deliverability tools (warm-up + placement tracking + domain health)

• Smart scheduling to book meetings from reply intent directly in Google Calendar

• Access to a massive verified contact database
  
  

Who it’s best for

• GTM leaders running large, multi-channel sequences

• Enterprise teams needing centralized reporting and CRM syn

• Agencies and sales ops that need volume plus tone control

• Teams already using Reply.io and wanting AI execution on top
  
  

Key edges

• 1B+ contacts means less dependence on third-party data vendors.

• Unified workspace for every touchpoint, no fragmented tools.

• Smart meeting detection + calendar booking to cut manual coordination.

• Deliverability and warm-up included, keeping volume safe as you scale.

• Autopilot/Copilot choice so you control risk and compliance.
  
  
  

Trade-offs / watch-outs

• The starter plan supports only one LinkedIn account; multi-rep teams must upgrade.

• Requires a short onboarding call (no instant checkout).

• Each new inbox still goes through a gradual ramp for deliverability protection.

• Private Slack support and custom playbooks are reserved for higher tiers.
  
  
  

Pricing

• Starter: $800 / $1,200 / $1,500 per month for 1K / 2K / 3K active contacts
  Includes unlimited mailboxes, warm-up, and 1 LinkedIn account.
  
  

• Growth: $2,500 – $5,000 / month (up to 5K contacts) with Slack support and white-glove onboarding.
  
  
  

Summary

Jason AI is for teams that need AI scale without losing visibility or deliverability.
It’s heavy infrastructure for serious operators — a true step up from 11x for enterprise-grade multichannel outbound.

Quick Takeaways

• Best for control & safety: Stamina.io

• Best for no-hands setup: AiSDR

• Best for pay-per-result: MeetChase

Which 11x AI Alternative Should You Pick?

The truth is, there’s no single “best” AI SDR platform.
It all comes down to how much control you want and how mature your GTM motion is.

Here’s the short version:

• If you want predictable deliverability and full visibility, go with Stamina.io. It’s deliverability-first, GTM-aligned, and lets you scale safely without burning domains.
  
  
  

• If you want zero effort and a white-glove team handling everything, AiSDR gives you fully managed outbound from setup to meetings.
  
  
  

• If you want performance pricing with low risk, MeetChase lets you pay only when results show up.
  
  
  

• If you’re data-driven and rely on timing signals, Coldreach.ai turns buying intent into contextually relevant outreach.
  
  
  

• If you want personalization that scales, Artisan AI combines data, warmup, and tone control in one system.
  
  
  

• If you want automation with a human safety net, Agent Frank (Salesforge) gives you warm-up, Slack support, and messaging oversight.
  
  
  

• If you’re running enterprise-level, multichannel sequences, Jason AI (Reply.io) is the most complete stack for large teams.

AI SDRs aren’t here to replace people; they’re here to replace wasted motion.
But you still need human judgment, clean data, and deliverability discipline to make AI work at scale.

11x AI is a good starting point if you just need motion fast. 

But once you care about reputation, inboxing, and predictability, tools like Stamina, Coldreach, or Agent Frank give you real control and accountability.

The best GTM teams don’t choose tools that “run everything.” 

They choose stacks that protect performance, let them steer, and scale sustainably.
