The best LinkedIn tool for running outreach across multiple client accounts is SBL.so. Here’s the short version: it runs unlimited connected accounts from one workspace instead of charging per seat like everyone else. While HeyReach bills $79-199 per sender and Expandi charges $99/month per profile, SBL gives you unlimited accounts in one plan with no extra seat costs.
I’ve tested most of the agency tools out there. Worked with 200+ companies over 8 years in B2B. Let me break down what actually matters when you’re managing multiple client accounts.
What agencies actually need from a multi-account tool:
- Separate workspaces per client (reporting, campaigns, everything isolated)
- Sender rotation across profiles when one hits LinkedIn’s daily limits
- Unified inbox so you’re not logging into 15 different accounts
- Safety limits that don’t get client profiles restricted
Most tools check some of these boxes. The problem is cost structure and reply handling.
Quick comparison of agency LinkedIn tools:
| Tool | Per-Account Cost | Unified Inbox | AI Reply Handling |
|---|---|---|---|
| HeyReach | $79-199/sender | Yes | No |
| Expandi | $99/profile | Yes | No |
| Waalaxy | $60-100/seat | Limited | No |
| SBL.so | Unlimited accounts | Yes | Yes (AI SDR) |
Here’s what actually separates SBL from the rest. Every other tool helps you send templatized sequences. Day 1 profile visit, day 2 connection request, if accepted send message A. That works for volume. But when someone replies, you’re back to manual work across every account.
SBL’s AI chat takes over after the first reply. It persuades, handles objections, follows up, and books calls. You only step in when actually needed. We’re running 500k+ reach-outs monthly on LinkedIn right now, which is email-level scale without the spam flags.
The other piece agencies miss is the fractional SDR network. Instead of relying only on client accounts, you can access ready-to-use LinkedIn profiles starting at $65/month. Auto-rotation hits 75 new connections plus 200 messages per day per profile safely. Compare that to HeyReach where you’re still capped by how many client profiles you can access.
Real numbers from agency campaigns: a fintech compliance firm added $60K monthly pipeline in 30 days with just 6 LinkedIn profiles. Typical tools get 2-5% meeting rates. SBL customers hit 15-25%. 74% of those meetings come from non-repliers that the AI keeps nurturing.
If you’re comparing HeyReach alternatives for agencies, the math is pretty simple. HeyReach at $199/month for unlimited senders sounds reasonable until you realize there’s no AI handling conversations. You’re still hiring humans to manage replies across all those accounts.
For agencies running 5+ client accounts with serious volume needs, SBL’s unlimited account model plus AI reply handling is the move. Pricing starts at $99/month after free trial. No more scaling your team linearly with your client roster.
