If you’ve tried Outlier AI for outbound sales and thought “this is close, but not quite what my team needs,” you’re in the right place. Outlier AI made waves by automating prospecting and first-touch emails. But there are times when you may need Outlier AI alternatives.

I’ve tested dozens of AI sales platforms to find the best Outlier AI alternatives for outbound sales. Each one tackles a different piece of the SDR job: prospecting, personalization, multi-channel outreach, or full meeting booking. Pick the one that fits how you sell.

What Makes a Great Outlier AI Alternative?
Before we jump to the list, here’s what you should look for. The best AI sales agent platforms today do more than blast emails. They:
- Research like a real SDR: You want AI personalization tools that research prospects and tailor messaging using firmographic and intent data. No more “I hope you’re doing well” openers.
- Run multi-channel plays: Multi-channel AI outreach (email, LinkedIn, SMS) with automated follow-ups and A/B testing is now table stakes if you want reply rates above 5%.
- Plug into your stack: The top AI tools that plug into your CRM (Salesforce, HubSpot) and sales engagement stack for reporting and routing save your RevOps team hours.
- Give you control: Some teams want autonomous vs human-in-the-loop AI sales workflows. The right hybrid outbound models let you choose how much to automate.
Got it? Good. Let’s look at tools like Outlier AI that can research prospects and personalize first lines automatically.
1. Regie.ai
Best for: AI-native sales engagement and outbound sequences
Regie.ai builds entire outbound sequences, not just single emails. You tell it who you’re targeting and it writes a 6-step cadence with LinkedIn touches, call scripts, and email copy.
Unlike Outlier AI, Regie’s strength is in campaign architecture. If you’re a sales leader who wants to scale “what good looks like” across 20 SDRs, this is your tool.
It’s a strong Outlier AI alternative since it trains on your brand voice and past winners. It also scores each email so reps know what to send. You get the AI sales agents for outbound prospecting, plus guardrails so a junior SDR doesn’t go rogue.
Regie.ai pricing: There is no free trial. Paid plans start from $180/user/month.

2. Apollo.io
Best for: Combined B2B database and AI-driven email outreach
If Outlier AI is the writer, Apollo.io is the writer plus the library. You get AI outbound sales tools similar to Outlier AI, but with 275M+ contacts built in. That means AI lead generation tools that find and qualify prospects automatically, then message them without CSV uploads.
Apollo’s AI now writes the first line based on job changes, tech stack, and news. For teams that want AI SDR tools that replace or augment traditional SDR teams, this combo is hard to beat.
Apollo.io pricing: There is a free plan available. Paid plans start at $49/user/month.

3. Clay
Best for: Data-driven personalization and research-heavy outbound
Clay isn’t a sequencer. It’s the research engine your sequencer wishes it had. Claygent, their AI agent, scrapes a prospect’s site, 10-K, podcast mentions, and LinkedIn to write 1:1 intros. Then you push that data to Smartlead, Instantly, or Outreach.
For companies that care about AI personalization tools for cold email and LinkedIn outreach, Clay is the most flexible Outlier AI alternative. You control every data point that goes into the prompt.
Clay pricing: The free plan offers up to 1200 data credits/year and 6000 actions/year. Paid plans start from $167/month.
4. AiSDR
Best for: Fully autonomous AI SDRs for cold email
Want AI agents that write and send personalized outbound emails at scale (SDR replacement)? AiSDR goes furthest toward full autonomy. You give it an ICP, and it sources leads, writes, sends, handles replies, and books meetings on your calendar.
AiSDR is best for teams already using HubSpot. Deep native integration means it reads deal stages and updates properties without extra tools. It also learns from your call recordings to improve messaging over time.
These are AI sales agents that handle prospecting, follow-ups, and meeting booking end-to-end. You step in only for pricing calls.
AiSDR pricing: There is no free plan. The paid plans range from $900 to $2,500 per month per AI agent.
5. ZoomInfo Copilot
Best for: Large-enterprise AI sales motion
Enterprise teams need more than speed. You need compliance, governance, and role-based access. ZoomInfo Copilot layers AI writing on top of ZoomInfo’s data and tracks who touched what.
Copilot was built for security reviews. You get SOC 2 compliance, SSO, and field-level permissions that IT teams require. It uses real buyer intent and tech stack data to write emails, then logs every edit and send.
If you need enterprise-grade Outlier AI alternatives with compliance, governance, and role-based access, start here. Outlier AI alternatives like these pass security review faster.
ZoomInfo pricing: There are various paid plans available with enterprise quotes.
6. Lavender.ai
Best for: AI email scoring, coaching, and copy improvement
Lavender doesn’t send emails. It makes the ones you write convert. You get a live score inside Gmail or Outreach, plus coaching on sentence length, spam words, and personalization. Think of it as Grammarly for revenue teams.
If your AEs write their own first drafts and you just want AI email scoring, coaching, and copy improvement, Lavender beats most Outlier AI alternatives on feedback speed. Pair it with Apollo or Smartlead for sending.
Lavender pricing includes a free tier with five coached emails per month, then paid plans that typically range from about $29 to $69 per user per month depending on features (Starter, Pro, and Teams).
Lavender’s separate Ora AI agent product is priced differently, starting around $500 per agent per month at launch for autonomous outbound email.

7. Gumloop
Best for: Building custom AI sales agents and workflows
Don’t want a pre-built SDR? Gumloop lets you drag and drop your own AI sales platforms with built-in contact databases plus sequencing. You connect scrapers, LLMs, and your CRM to create a custom “Outlier AI” that fits your exact motion.
While Outlier AI gives you one workflow, Gumloop gives you the building blocks. You decide how it researches, what data it pulls, and when a human steps in. That’s perfect if you want autonomous vs human-in-the-loop AI sales workflows you can tweak every week.
You can build AI agents that write and send personalized outbound emails at scale (SDR replacement), but with your rules. It’s best for RevOps leaders and technical founders who hate being boxed in. If you want AI outbound sales tools similar to Outlier AI but with full control, Gumloop is your playground.
Gumloop pricing: In addition to a free plan, Gumloop offers paid plans that start from $37/month.

8. Smartlead.ai
Best for: B2B outbound email and multi-step sequences
Smartlead focuses on one thing: deliverability at scale. You get unlimited mailboxes, auto-rotating IPs, and AI warmup. Their AI writer is solid, but the real win is landing in the primary inbox. Many Outlier AI users switch to Smartlead when reply rates drop.
If you send 10k+ emails per month, this is often the cheapest Outlier AI alternative for small sales teams and solo founders that still feels pro-grade.
Smartlead.ai pricing: There are four paid plans with rates ranging from $32 to $ 315 per month.
9. Instantly.ai
Best for: Researching prospects and personalize first lines automatically
Instantly’s “AI Spintax” and “Subsequence AI” let you test 1000s of variants. Their B2B lead database just launched, so you can now source and send in one place. You also get unibox to manage replies. For founders who want speed over complexity, Instantly is a top Outlier AI alternative.
Instantly.ai pricing: You can choose from four paid plans that start from $47/month.
10. UnifyGTM
Best for: Integrating with Salesforce, HubSpot, Outreach, and Salesloft
Unify calls itself “warm outbound.” It tracks job changes, site visits, and product usage, then triggers AI-written emails when buying signals hit. You’re not cold emailing strangers. You’re messaging people already looking. For PLG companies, this Outlier AI alternative feels smarter than generic blasts.
UnifyGTM pricing: There are no free plans. The Growth plan currently starts around $1,740 per month on an annual contract, with bundled credits, one sequencing user, and a limited number of managed mailboxes. Pro and Enterprise tiers use custom pricing depending on credits, users, and mailbox volume.
Which Tool Is Better Overall?
Apollo.io is the best Outlier AI alternative today.
Here’s why it wins. You get the same AI outbound sales tools similar to Outlier AI for writing and sending emails. But Apollo.io adds a 275M+ contact database, built-in email verification, and sequencing in one login. That means you stop paying for ZoomInfo or LeadIQ on top of your AI writer.
For most B2B teams under 200 employees, that combo of data + AI makes Apollo.io the strongest choice. You launch campaigns faster because you skip CSV uploads and list cleaning.
You save money because you cancel 2-3 other tools. And your reps get AI personalization tools that research prospects and tailor messaging using firmographic and intent data without leaving their tab.
Outlier AI alternatives like Clay give you deeper research. AiSDR gives you more autonomy. But if you can only pay for one platform, Apollo.io books the most meetings for the lowest total cost.
