TL;DR – 20 AI SDR Tools We Tested

1. Agent Frank – The only tool that gave us reply-aware AI, inbox placement control, and real booked meetings. Built for pros.
   
   
2. AiSDR – Best if you use HubSpot. Syncs CRM lists, runs follow-ups. Great for lead nurturing, weak for cold.
   
   
3. 11x.ai – Fully-managed AI SDR agents. Great if you want hands-off results. Expensive, no reply logic, limited control.
   
   
4. Instantly.ai – Scales cold email fast. But the reply logic is poor, and it’s more about blasting than closing.
   
   
5. Smartlead.ai – Good sending infrastructure. Inbox rotation is solid. But AI content feels generic.
   
   
6. Outreach.io – Powerful sequencing and CRM sync. Great for big teams, but too rigid and pricey for lean ops.
   
   
7. Regie.ai – Content creator for sequences, not a true SDR. Useful, but needs to be paired with a sending engine.
   
   
8. Salesloft – Reliable, structured engagement. But bloated UX, stale AI, and locked-in contracts make it feel stuck in 2019.
   
   
9. Lemlist – Visual-first cold emails that stand out. Not AI-driven. Great for replies, weak for smart scaling.
   
   
10. Apollo.io – Decent enrichment. The AI layer is weak. Better as a data + CRM platform than a true SDR.
    
    
11. ZoomInfo – Enterprise-grade AI over rich data. Great for big teams, not for startups or lean ops.
    
    
12. Reply.io – Multichannel sequencer with basic AI add-ons. Still feels like a traditional outreach tool.
    
    
13. Mailshake – Cold email tool with smart suggestions. Decent AI, but limited logic and no true reply awareness.
    
    
14. Lusha – Fast LinkedIn enrichment. Great for data pulls, but no outreach, AI, or automation.
    
    
15. LeadIQ – LinkedIn-first data capture. Quick and simple, but flaky data and limited functionality.
    
    
16. Clay – Workflow engine for prospecting. Insanely customizable. But steep learning curve, not a sender.
    
    
17. Lavender.ai – AI email coach for Gmail/Outlook. Helps you write better, but doesn’t send or manage replies.
    
    
18. Mixmax – Gmail-native SDR tool. Great for solo teams, weak on multichannel and automation depth.
    
    
19. Snov.io – Budget-friendly all-in-one starter. Good for lean teams, but not scalable for serious ops.
    
    
20. Hunter.io – Great for fast, accurate email lookups. No AI, no sending — pure data tool.

If you’ve got reps, CRM data, and process... Outreach turns it into a machine.

#7. Regie.ai – The AI SDR Tool That Doesn’t Send, Just Sells (Through Better Copy)

Regie.ai is an AI-powered copywriting tool built for SDRs, sales teams, and agencies who send cold outreach every day, but want that outreach to stop sounding like spam.

You feed in your product, persona, and campaign goal.

Regie writes full multichannel sequences: email, LinkedIn, and even call scripts.

It scores the quality, gives feedback, and helps you adjust before launch.

It helps you say the right thing, the first time.

‍

✅ Pros vs ❌ Cons of Regie.ai

Regie.ai Pricing & Setup

Regie pricing isn’t fully public, but based on reviews and usage:

• Starts at ~$35k grows with seats and features
  
  
• You’ll need to bring your sender (like Outreach, Salesforge, or Instantly)
  
  
• Setup is fast — 1–2 hours to get sequences flowing
  

Not cheap. But it can replace weeks of writing and testing with AI-generated flows that sound close to human.

• You want to improve reply rates with persona-based copy

• You’re a solo founder sending a few emails per week
  
  
• You expect a perfect copy without human input
  

Regie.ai won’t book meetings. It’ll just help you write the emails that do.

If your sequences feel lifeless, generic, or templated, this tool fixes that.

Use it with your sender of choice, and your cold outreach will finally stop sounding cold.

‍

#8. Salesloft – The Legacy AI SDR Platform That Feels Stuck in 2019

Salesloft is a sales engagement platform that helps outbound teams run cadences across email, calls, and social touches, with built-in analytics and Salesforce integration.

It’s not a modern AI SDR.

It’s a traditional sales tool with some AI features bolted on after the hype cycle.

If you’re a large team using Salesforce and care more about structure than flexibility, it might still work.

But for most others, there are faster, leaner, and smarter alternatives in 2025.

Key Features of Salesloft

• 📬 Cadence Builder – Still one of the better UI experiences for multi-step outbound
  
  
• 🧠 Conversations AI – Supposed to rival Gong. In reality, it barely functions
  
  
• ✍️ Templates + AI Assist – Speeds up writing, but personalization is weak
  
  
• 🔌 Salesforce Integration – Decent, though clunky in some setups
  
  
• 📊 Analytics + Dashboards – Strong reports if they load without delay
  
  
• 📉 Deliverability – Surprisingly solid out of the box
  

Salesloft helps you scale outbound.

But the AI part? Mostly fluff.

✅ Pros vs ❌ Cons of Salesloft

Salesloft Pricing

• ❌ No public pricing
  
  
• 📞 Must book a demo and go through sales
  
  
• 💸 Expect pricing to start in the $1K–$2K/month range, depending on seats and features
  
  
• 🔐 Contracts = 12 months minimum, with auto-renewal clauses buried deep
  

Let’s be blunt:

You’ll probably pay too much.

And if you don’t cancel 60 days in advance, they’ll lock you in again.

Should You Use Salesloft?

✅ Use Salesloft if:

• You have an ops team to babysit the platform
  
  
• You’re fully committed to Salesforce as your CRM
  
  
• You care more about cadence structure than AI innovation
  
  
• You’re an enterprise team with a repeatable process
  

❌ Avoid Salesloft if:

• You’re a startup, a small team, or a HubSpot user
  
  
• You want actual AI SDR capabilities, not templates
  
  
• You value flexibility, support, or rapid execution
  
  
• Have you ever been burned by a sneaky contract renewal (it’s coming again)
  

Salesloft looks great in demos. But reality hits fast.

If you’ve got the internal muscle to deal with bugs, support delays, and outdated features, it’s fine.

But if you want a modern AI SDR tool that evolves with your team, you’ll find better elsewhere.

If you want plain outreach, use a sequencer.

If you want visual-first, high-attention email, Lemlist delivers.

✅ Pros vs ❌ Cons of Lemlist

Lemlist Pricing (2025)

Lemlist is affordable for creatives, but not ideal if you want deep automation or reply intelligence.

‍

Should You Use Lemlist?

✅ Use Lemlist if:

• You want to send cold emails that visually stand out
  
  
• You’re an agency or brand running lots of outreach

❌ Avoid Lemlist if:

• You want AI help writing content or managing replies
  
  
• You’re running low-effort, high-volume campaigns
  
  
• You’re looking for deep CRM sync or advanced logic
  
  
• You need flexible support and refund policies
  
  

Lemlist makes your outreach feel human again.

No, it’s not built on GPT.

No, it won’t write or respond for you.

But if you want to break the pattern and actually get cold prospects to respond, this is one of the most creative cold email tools on the market.

#10. Apollo.io – The All-In-One SDR Stack If You’re Starting from Scratch

Apollo.io is an all-in-one sales platform built for SDRs who want to combine lead discovery and outreach in one tool.

You can search over 260M+ verified contacts, filter by job title, tech stack, company size, then drop them into automated email cadences or call them directly from inside the platform.

It’s not reply-aware.

It’s not hyper-personalized.

But for speed and simplicity, it works.

Key Features of Apollo.io

• 📇 260M+ Contact Database – Emails, phone numbers, verified job data

• 💰 Free Plan – Start without paying a cent
  

This isn’t an AI SDR that thinks for you.

It’s a starter pack that helps you execute faster.

‍

✅ Pros vs ❌ Cons of Apollo.io

Apollo.io Pricing (2025)

If you’re solo or scaling slowly, the free and Basic plans are solid.

For real automation, a Professional is where it starts.

Should You Use Apollo.io?

✅ Use Apollo.io if:

• You want leads + outreach in one place
  
  
• You’re building outbound from the ground up
  
  
• You need a tool that just works without complexity

❌ Avoid Apollo.io if:

• You need AI reply handling or advanced logic
  
  
• You want guaranteed data accuracy or enrichment depth
  
  
• You’re focused on deliverability control or warm-up customization
  
  
• You care about high-touch personalization or ABM
  

Apollo.io is a great first SDR tool, but not your forever tool.

It covers the basics:

Leads. Emails. Calls. Tracking.

If you want smarter sequences, better inboxing, or AI-driven replies, you’ll outgrow it fast.

But for $0 to $79/month, you can do a lot more than LinkedIn scraping and CSV juggling.

#11. ZoomInfo – Best AI SDR Tool for Big Sales Engines That Need Firepower

ZoomInfo is a B2B intelligence platform designed for enterprise sales teams that need massive contact coverage, real-time intent data, and tight CRM integration.

It tells you:

• Who to target
  
  
• Why now is the right time
  
  
• How to reach them
  
  
• And who else is involved in the deal
  

It’s less “AI SDR” and more AI fuel for your outbound machine.

Key Features of ZoomInfo

• 🧠 Buyer Intent Signals – Tracks which companies are researching your keywords
  
  
• 📇 Massive Contact Database – 260M+ verified contacts + firmographic filters

‍

✅ Pros vs ❌ Cons of ZoomInfo

ZoomInfo Pricing (2025)

❌ Not publicly listed

 Expect to pay around $250/month (or more), billed annually. Contracts are strict; make sure to read the fine print before signing.

Should You Use ZoomInfo?

✅ Use ZoomInfo if:

• You’ve got a dedicated sales team with real volume
  
  
• You need intent signals + deep filters to find high-probability leads
  
  
• You want to automate CRM enrichment at scale
  
  
• You’re already using Outreach, Salesforce, or Salesloft daily
  

❌ Avoid ZoomInfo if:

• You’re a startup or small team just testing outbound
  
  
• You want cold email outreach + copywriting built-in (this isn’t that)
  
  
• You need pricing flexibility, monthly billing, or easy cancellation
  
  
• You care about support that doesn’t pressure you at renewal time
  

ZoomInfo is like giving your sales ops team a tank.

If your outbound engine is already running, this pours rocket fuel into it.

But if you're still building your process? It’ll feel like overkill.

Great data, strong integrations, solid intent signals, at a price.

Just read the contract before you sign it.

✅ Pros vs ❌ Cons of Reply.io

Reply.io Pricing (2025)

Note: If you want the full suite, multichannel + AI + calling, your actual monthly cost will exceed $100/user.

Still cheaper than locking into Outreach or Salesloft.

Should You Use Reply.io?

✅ Use Reply.io if:

• Your SDRs are juggling email + LinkedIn + SMS, + voice
  
  
• You’re managing outreach for multiple clients or brands
  
  
• You already have leads and want to reach them everywhere
  
  
• You want customizable automation without enterprise-level bloat
  

❌ Avoid Reply.io if:

• You want a clean UI and zero setup friction
  
  
• You’re new to multichannel campaigns — there is a learning curve
  
  
• You need AI SDR-level reply handling (Reply still requires manual oversight)
  
  
• You’re looking for a “done-for-you” system — this tool gives you control, not shortcuts

Reply.io is built for teams that don’t want limits.

You get multichannel campaigns, A/B testing, CRM sync, and AI help, all under one roof.

But it’s not for beginners.

And it’s not for people who want an AI SDR that thinks for them.

If you already have leads and just need to hit them faster, smarter, and at scale?

This is your multichannel outreach hub.

16. Clay – Best for Workflow Nerds and Hyper-Customized Prospecting

Clay isn’t your typical AI SDR tool. It’s more like a no-code sales data engine.

You don’t send emails inside Clay.

You build everything before the outreach, data, personalization, enrichment, and logic.

If you’ve ever had to Google someone’s podcast appearance, scrape their tech stack, then paste it into an email manually…

Clay replaces that entire process.

‍

What features does Clay offer?

Clay does what most AI SDR tools don’t:

It gives you granular control over data and plugs perfectly into your existing email systems.

• Pull 50+ enrichment sources into one workflow
  
  
• Use OpenAI to personalize messages at scale
  
  
• Sync clean leads directly into Salesforge, Apollo, Instantly, or HubSpot
  
  

Clay won’t send the emails, but it’ll make your inputs 10x sharper.

Clay Pricing

✅ Pros and ❌ Cons of Clay

Who Should Use Clay?

Clay is like giving your SDR team superpowers before the email is even sent. 

It’s not for beginners or teams who want plug-and-play.

#20. Hunter.io – Best for Fast, Accurate B2B Email Lookup (Nothing More, Nothing Less)

If your sales process starts with building a list and you’re still guessing emails, Hunter.io fixes that.

It doesn’t send emails, write sequences, or manage inboxes.

But it’s really good at one thing: finding and verifying emails.

‍

What Features Does Hunter.io Offer?

• Domain Search – Find all emails associated with a company
  
  
• Email Verifier – Reduce bounces with pre-send validation
  
  
• LinkedIn Extension – Grab emails while browsing profiles
  
  
• Bulk Tools – Upload a CSV, get emails + statuses
  
  
• CRM Integration – Syncs with Salesforce, HubSpot, and more
  
  
• API + Exports – Plug data into your existing flow
  
  
  

Hunter.io Pricing

✅ Pros and ❌ Cons of Hunter.io

Who Should Use Hunter.io?

• SDRs doing manual prospecting from LinkedIn or company sites
  
  
• Teams that already have a cold outreach tool but need emails
  
  
• Founders scraping domains for contact info

Hunter.io is a sniper tool, not a sales platform.

If all you care about is getting clean, valid business emails fast, it nails the job.

But don’t expect sequences, warm-up, or campaign management.

It’s best used with tools like Salesforge, Reply.io, or Snov.io to power a complete outbound system.

For data-first SDRs and spreadsheet-happy founders, it’s a solid addition to the toolkit, just know what it does (and doesn’t do).

‍

Conclusion

After taking 20+ tools’ demos, one thing became clear:

Most “AI SDR” platforms either write emails or send them. 

Few handle replies. Fewer still control inbox placement. 

And nearly all require duct-taping 3–5 tools just to run one campaign.

If you’re serious about booking meetings, not just sending emails. 

Agent Frank is the only tool that consistently does it all.

• Real replies, not vanity metrics
  
  
• Warm-up + inbox setup built-in
  
  
• No extra tools or manual chasing
  
  
• Actually feels like hiring an SDR, not babysitting software
  

👊 If you’re tired of stacking tools that don’t talk to each other, it’s time to hire Agent Frank.‍

👉 Book your demo and start your first campaign this week.
