Let me tell you something that took me way too long to figure out. Most LinkedIn automation tools are basically the same thing wearing different hats. You get a dashboard, some sequence builder, maybe a few if-else conditions, and everyone calls it AI. Expandi and SBL.so both show up in every “best LinkedIn automation tools” list, but they’re fundamentally different products built for different problems.
TL;DR: Expandi vs SBL.so
Expandi ($99/month) is a LinkedIn campaign automation tool with conditional workflows, AI-assisted reply drafting, and 7-day free trial. SBL.so ($99/month Starter) is an AI SDR that handles conversations automatically across LinkedIn, WhatsApp, and Email. Expandi excels at structured sequence automation. SBL.so wins if you need AI conversation handling, multichannel outreach, and lead generation without hiring SDRs.
I’ve tested both. Ran campaigns, broke stuff, got a few accounts flagged (yeah, that happened), and finally understood what actually matters when you’re trying to scale LinkedIn automation without hiring an army of SDRs.
So here’s my honest breakdown of Expandi vs SBL.so. No fluff, no affiliate links pushing you toward whoever pays more. Just what I learned the hard way.
The Core Difference You Need to Understand First
Before we get into features and pricing, let me explain the fundamental difference between these two tools. Because if you miss this, you’ll pick the wrong one.
Expandi is a campaign automation tool. It sends messages, follows up, visits profiles, and does all that on autopilot. It now includes AI-assisted campaign creation and reply drafting through connections with Claude, ChatGPT, or other AI assistants. But when someone replies with a complex question or objection? That’s still largely on you.
SBL.so is an AI SDR. It doesn’t just send messages. It actually handles the conversation after someone replies. Qualifies leads, handles objections, pushes toward booking calls. You step in when you want to, not because you have to.
That’s not a small difference. That’s the difference between hiring a postman and hiring a sales rep.
Feature by Feature Breakdown
Alright, let’s get into the specifics. I’m gonna cover what matters most for anyone doing serious LinkedIn outreach in 2027.
Safety and Account Protection
LinkedIn has been aggressive about banning automation. They’re not messing around. So safety isn’t optional, it’s the whole game.
Expandi’s approach: They use dedicated country-based IP addresses. Each account gets its own IP, so you’re not sharing infrastructure with some guy sending 500 connection requests a day. They also have automatic warm-up and adjustable daily action ranges built in.
SBL.so’s approach: Account rotation across multiple profiles, IP rotation, and what they call human behavior mimicry. Random delays, variable timing, patterns that don’t look robotic. They advertise up to 75 new connections per day safely, which is higher than most tools dare to promise.
That said, here’s what nobody tells you: LinkedIn’s official policy prohibits third-party software that automates activity on the platform. This includes automated messages, connection requests, profile visits, and data scraping. Neither tool is “LinkedIn-approved.” The safety features these tools offer reduce risk, but they can’t guarantee zero restrictions.
I think the real question isn’t “which is safer” but “which lets me do more while staying within reasonable limits.” And that’s where things get interesting.
Expandi vs SBL.so: Outreach Limits and Scalability
Here’s where my brain started to hurt during testing.
Expandi has adjustable daily action ranges. You can configure connections, messages, InMails, and event invitations based on your account’s warm-up status. They emphasize smart algorithms to stay within safe zones.
SBL.so takes a different approach. They advertise up to 75 new connections and 200 messages to first-degree connections per day per account. Monthly connection limits are up to 800 for premium accounts and 400 for free accounts.
Where SBL.so really stands out is multi-account management. You can connect unlimited LinkedIn accounts to one workspace. So if you connect 50 profiles, you’re looking at serious volume. That’s email level scalability on LinkedIn.
They also have this Fractional SDR Network thing. Basically verified LinkedIn users who can run outreach campaigns from their real profiles. Profile rental starts at $65 per month for less than 10 profiles, dropping to $59 per month for 10+ profiles. Sounds wild, but it works for agencies who need scale without creating fake accounts.
The Conversation Handling Problem
This is the part most comparison articles skip over. And honestly, it’s the most important part.
Let’s say you run a campaign. You send 1,000 connection requests. 300 people accept. 50 people reply with some interest. Now what?
With Expandi, you can use their AI-assisted reply writing through Claude or ChatGPT connections. It helps draft responses faster. But you’re still managing conversations yourself, deciding what to send, when to follow up.
With SBL.so, their AI handles the conversation. And I don’t mean some chatbot that says “Thanks for connecting! When can we chat?” I mean actual conversation handling in over 100 languages. Objections, questions about pricing, qualifying questions, pushing toward a call. The system learns what works and adapts.
They even have a manual intervention feature. If the AI gets stuck on something it wasn’t trained for, it flags it for you instead of sending garbage. You handle it once, the system learns, and it doesn’t ask again for similar situations.
That’s the difference between a tool and an AI SDR.
Expandi vs SBL: Message Personalization
Both tools let you personalize messages with variables like first name, company, job title. That’s table stakes in 2027.
Expandi uses dynamic placeholders and now offers AI-powered campaign creation and reply writing through external AI assistants. The messages are better than pure templates, but the AI assistance is more about drafting help than autonomous personalization.
SBL.so does something different. You can send PDFs, images, videos, and here’s the crazy part, voice messages that sound exactly like you. On the Pro plan, you upload a voice sample, and the system generates personalized voice notes for thousands of prospects. Nobody else is doing this at scale.
I sent 200 voice note outreach messages in one campaign. Response rate was almost double my text-only campaigns. People are so used to templated garbage that a voice message feels refreshingly human.
Multi-Channel Capabilities
LinkedIn alone isn’t enough anymore. Your prospects are everywhere.
Expandi focuses primarily on LinkedIn. They have integrations and can connect with other tools through Zapier, but the core product is LinkedIn outreach.
SBL.so runs on LinkedIn, WhatsApp, and now Email with pre-warmed mailboxes. Same lead, multiple channels, unified inbox. You don’t lose context when you follow up on WhatsApp after connecting on LinkedIn.
For B2B where decision makers are on LinkedIn but communication often shifts to WhatsApp (especially in regions like Europe and Asia), this matters a lot.
Expandi vs SBL.so: Analytics and Insights
Expandi gives you a solid dashboard. Campaign performance, engagement tracking, notes and tags on conversations. Standard stuff that helps you optimize.
SBL.so goes deeper because they’re tracking conversations, not just messages. You see lead sentiment, buying intent signals, what objections came up, what worked in your outreach and what didn’t. Qualitative insights, not just numbers.
If you’ve ever wondered “why aren’t people responding to my outreach,” SBL’s analytics actually tell you. Expandi’s analytics tell you that people aren’t responding. Big difference.
Campaign Building: Expandi’s Workflow Builder vs SBL’s Vibe Campaigns
Expandi has beefed up their campaign builder. They now offer a drag-and-drop interface with 19 actions and 11 conditions. If-then logic that adapts to connection acceptance, replies, and engagement. It’s more powerful than the basic sequence tools from a few years ago.
SBL.so introduced something called “Vibe Campaigns” that I haven’t seen anywhere else. You describe in plain language what you want: your ideal customer, your offer, the tone you’re going for. The system auto-builds everything: targeting logic, outreach copy, conversation flows, and follow-ups.
I tested it by typing “founders at B2B SaaS companies with 10-50 employees who might need help with LinkedIn outreach.” Fifteen minutes later, I had a live campaign. Not perfect on the first try, but close enough that I only tweaked a few things.
Expandi’s builder gives you more granular control. SBL’s approach gets you to a working campaign faster.
Lead Generation and Intent Signals
This is where SBL.so has expanded significantly. Their Starter plan includes 1,000 ICP-matched leads per month with Sales Navigator extraction. The Pro plan bumps this to 2,000 premium leads plus intent signals like job changes, funding events, and competitor engagement monitoring.
Expandi focuses on campaign execution rather than lead sourcing. You bring your own lists, they help you reach them.
For teams that need both lead generation and outreach automation in one platform, SBL.so offers a more complete package.
Expandi vs SBL.so: Pricing Comparison
Let’s talk money because this is where a lot of people make their decision.
Expandi: $99 per month. They offer a 7-day free trial. Annual billing gets you a 20% discount.
SBL.so Starter: $99 per month. Includes 2 outreach seats, with additional seats at $39/month. 7-day free trial, no credit card required.
SBL.so Pro: $189 per month. Includes 4 outreach seats, 2,000 ICP-matched leads, premium intent signals, built-in CRM, and AI-cloned voice messaging.
Wait, same entry price? Yeah. But they’re not identical. Expandi’s $99 gets you one account focused on campaign automation. SBL.so’s $99 gets you 2 outreach seats, unlimited workspaces, AI chat handling, and LinkedIn + WhatsApp capabilities.
If you need profile rental for scaling, SBL.so offers that starting at $65 per profile per month (or $59/month for 10+ profiles).
The real cost difference is labor. With Expandi, you still need someone handling the back-and-forth of conversations. With SBL.so, the AI handles most of that. Factor in what your time is worth or what you’d pay a VA or SDR, and the math changes dramatically.
Who Should Use Expandi
Look, Expandi isn’t a bad tool. It’s been around since 2018, has tons of users, and they’ve built solid infrastructure. Here’s when it makes sense:
- You have a team already handling LinkedIn conversations manually
- You want granular control over campaign workflows with 19 actions and 11 conditions
- You prefer AI-assisted reply drafting over fully autonomous conversation handling
- You already have your lead lists and just need campaign execution
- You’re comfortable managing one primary account
If you’re already using Expandi and it’s working, I’m not saying switch. But if you’re evaluating tools for the first time or looking to scale, keep reading.
Who Should Use SBL.so
SBL.so makes more sense when:
- You want to scale beyond what one person can handle manually
- Replying to LinkedIn messages is eating your calendar
- You need sales automation for a small team without hiring SDRs
- You want multichannel outreach (LinkedIn + WhatsApp + Email)
- You’re an agency managing multiple client accounts with unlimited workspaces
- You need lead generation and intent signals built into the same platform
- You want to test ideas fast with Vibe Campaigns
The AI conversation handling is the killer feature. If you’ve ever thought “I wish someone else could handle these LinkedIn replies for me,” that’s literally what SBL.so does.
Common Questions About Expandi vs SBL.so
Which tool is safer for my LinkedIn account?
Both are cloud-based and use various techniques to stay safe. Expandi uses dedicated country-based IPs, automatic warm-up, and adjustable limits. SBL.so uses behavior mimicry, account rotation, and smart delays. Neither can guarantee zero restrictions because LinkedIn’s policy prohibits third-party automation entirely. Your best protection is staying well within recommended limits and mixing automated outreach with genuine engagement.
Can I use multiple LinkedIn accounts with these tools?
Expandi’s pricing is straightforward for single accounts. SBL.so includes unlimited workspaces and supports multiple accounts, with outreach seats determining how many can run campaigns simultaneously. If you’re planning to run 5+ profiles, SBL.so’s structure is more cost-effective, especially with profile rental options.
How long until I see results?
Both tools typically show results within 2 to 4 weeks. Your first week is usually testing and optimizing messages. By week 3 or 4, you should have a feel for what’s working. SBL.so’s analytics help you figure this out faster since you can see why people are or aren’t responding.
What about LinkedIn’s crackdowns?
LinkedIn is aggressive about restricting automation. Both tools have adapted with smarter limits and behavior patterns. The key is staying within 20 to 30% of maximum daily limits and mixing automated outreach with genuine engagement. Don’t just blast messages, actually use LinkedIn like a real person would.
Can these tools help with content and comments?
Expandi has basic engagement features like profile visits and can be part of multi-step campaigns. SBL.so has a comment to DM automation feature where you can auto-DM people who comment on your posts or even your competitor’s posts. Paste a post URL, set a trigger keyword or intent, and it handles the rest.
Which has better integrations?
Expandi integrates with various tools and offers connections to AI assistants like Claude and ChatGPT. SBL.so integrates with HubSpot, Google Sheets, and offers APIs, MCP, and webhooks for custom integrations. Depends on your tech stack which matters more.
Does Expandi have a free trial now?
Yes. Expandi currently offers a 7-day free trial, which is a change from their earlier demo-only approach.
The Honest Truth About LinkedIn Automation in 2027
Here’s what nobody tells you in these comparison articles.
Most LinkedIn automation tools are solving the wrong problem. They focus on sending more messages when the real bottleneck is handling conversations. You can send 1,000 connection requests with any tool. The question is what happens when 50 people reply.
With traditional tools like Expandi, you hit a ceiling. You can only scale as fast as you can type (or as fast as your AI-assisted drafting helps you type). Sure, you can hire VAs or SDRs, but now you’re managing people and paying salaries and dealing with training and turnover.
What SBL.so figured out is that the valuable part isn’t sending the message. It’s the conversation that follows. That’s where deals happen or don’t happen. That’s where you qualify leads, handle objections, and book calls.
When I tested SBL.so, I ran a campaign with 2,000 reach-outs. Had conversations happen automatically. The AI qualified leads, handled basic objections, and booked calls for me. I literally showed up to calls with people who were already sold on talking to me.
Try doing that manually or with a sequence tool. You’d need at least one full-time person just managing inbox.
The Shift Toward Intelligent Automation
There’s a broader trend happening in sales automation that explains why tools like SBL.so exist. The industry is moving from simple workflow automation to what analysts call “intelligent automation” or “agentic process automation.”
Traditional automation tools (like Expandi) are great at orchestrating actions. Send this message, wait two days, send another. That’s workflow automation. Expandi has evolved with AI-assisted campaign creation and reply drafting, which helps but doesn’t fundamentally change the model.
AI SDR tools go further. They don’t just follow scripts. They make decisions based on what prospects say. They adapt. They learn what works. That’s closer to how a human SDR operates, except it never sleeps and can handle hundreds of conversations simultaneously.
This isn’t just SBL.so. The whole category of AI SDR tools has exploded. But SBL.so is one of the few focused specifically on LinkedIn, WhatsApp, and now Email, which makes it particularly relevant for B2B outreach.
My Recommendation
If you’re a solo founder or one-person team doing casual LinkedIn outreach and you want granular control over every step of your campaigns, Expandi is solid. It’s proven, has good infrastructure, and the AI-assisted features help with drafting.
If you’re serious about using LinkedIn as a sales channel, if you want to scale beyond what you can manually handle, if you’re tired of spending hours replying to messages, SBL.so is the better choice.
The AI conversation handling changes everything. It’s not just automation anymore. It’s like having an SDR that never sleeps, never gets tired, and gets better the more it talks to people.
And look, I know this sounds like a sales pitch. But I genuinely think most comparison articles miss the point by focusing on feature lists instead of asking “what problem am I actually solving.”
The problem isn’t sending more messages. The problem is having meaningful conversations at scale. That’s what separates tools that get you followers from tools that get you customers.

Pick based on what you actually need, not what sounds fancier. If Expandi’s workflow builder and AI-assisted drafting work for your style, great. If you need more and you’re tired of being the bottleneck in your own sales process, give SBL.so a shot.
Either way, stop spending hours doing what software should do for you. That’s the whole point of automation.
