For the past year we've been running outbound the way most teams do.

Smartlead for cold email. HeyReach for LinkedIn. Lemlist for the signal-based stuff (job changes, funding rounds, etc).

The problems piled up fast:

Three logins, three dashboards, three billing cycles

Our list lives in one tool, our LinkedIn motion in another, our signals in a third. Nothing talks to each other

Automation is shallow in each one. You can't say "if this person changes jobs, wait 5 days, then send a connect, then if they accept, send this email from this mailbox." You end up doing half of it manually

Onboarding new SDRs takes a week just to learn the stack

We were spending around $250 a month and still not getting the output we expected

So we built Superkabe.

It runs cold email, LinkedIn outreach, and signal-based campaigns in one place. Same list, same sequences, same inbox for replies. The signal layer picks up things like job changes and funding rounds and fires the right step automatically, whether that's an email or a LinkedIn touch. Mailbox healing is built in so domains stop burning.

Roughly a third of the cost of running the three tools separately.

Right now it's free for early users while we polish the rough edges. We're looking for people running real outbound campaigns who can give us honest feedback.

If you want in, DM me.

Hey folks,

I'm building a cold email platform — yes, another one — and instead of pretending I have all the answers, I'd rather just ask the people actually running campaigns every day.

If you use Smartlead, Instantly, or have churned from either of them, I'd love to know:

- What's the one thing that consistently makes you want to throw your laptop?

- Where does deliverability actually break down for you, and how much of that do you blame on the tool vs. your setup?

- Warmup — do you trust it? Do you even believe the dashboards anymore?

- Pricing — fair, or does the math get out of hand fast?

- Anything in the UX or workflow that feels stuck in 2021?

- Features you've been waiting on for 6+ months that nobody's shipped?

Not trying to pitch anything here. Genuinely doing the research before I keep building, because I'd rather hear hard truths now than ship something that solves problems nobody has.

Roast away. Specific examples > general complaints. Will read every reply.

Thanks 🙏

Hey guys, I have been in the SaaS industry for almost 6 years and I wanna connect with outbound agency owners to help me bring my product into the outbound market.

Please DM me for further information. Happy to get on a call as well to discuss this further.

Notice: Looking for experienced agencies

For about a year I was doing cold email the way everyone tells you to:

Smartlead or Instantly for sending (~$97/mo)

A warmup tool (~$300/mo)

MillionVerifier or ZeroBounce for validation (~$50/mo + credits)

A spam tester (~$30/mo)

Some "deliverability monitor" (~$40/mo)

Inbox rotator for the load balancing everyone insists you need

That's $300–500/mo easy, and none of it talks to each other. The validator flags a lead as risky → the sender doesn't care. The warmup tool says the mailbox is healthy → the actual bounce rate disagrees. You upload a fresh list and half the leads are already mid-sequence in another one of your campaigns and nothing flags it. Each tool has its own dashboard with its own incomplete view of the same problem.

And half these tools are theater underneath. The "AI deliverability protection" on most senders is a daily send cap with a fancy name. The "warmup" is bot mailboxes opening each other's spam. None of them have the actual signals — Google Postmaster reputation, FBL events, complaint rates — feeding back into sending decisions.

Got fed up about 8 months ago and started building. It's live now as Superkabe.

What I actually tried to fix:

One data model. Leads → validation → sending → reputation, all wired. A bounce in one campaign auto-suppresses across every campaign in your org. Catch-all flag from validation changes how the sender treats the address. Recipient-domain complaint rate gates new enrollment.

Recovery pipeline that's actually a recovery pipeline. 5 phases (paused → quarantine → restricted → warm → healthy) with thresholds from M3AAWG BCP, Google/Yahoo Feb 2024 sender rules, RFC 8058 unsubscribe headers. Not a daily cap dressed up.

Cross-campaign dual-enrollment detection so the same lead can't be in 3 of your campaigns at once getting bombed.

AI copy gen baked in. Validation credits included in tier. Real-time deliverability protection bundled, not a "premium add-on."

Cheaper than the stack above. Significantly.

Not claiming it's perfect. Native warmup is still half-built — honestly I think traditional bot warmup is broken and the recovery pipeline replaces most of what it's trying to do, but the messaging there isn't fully settled. Catch-all detection on the lower tiers leans on DNS heuristics until you're on a plan with API-backed verification. We don't do lead enrichment — bring your own list (Apollo, Clay, scraped, whatever you already use).

Sharing because I'm pretty sure I'm not the only one paying for 6 dashboards I don't enjoy. If you're stuck in that stack and want to try it: superkabe.com. DMs open for feedback / brutal critique.

What does your current stack look like, and what's it costing you? Curious what the median is for solo / small-team cold emailers in 2026.
