The Lemlist alternative for founders who want replies, not seats.
Same AI cold-outreach playbook. Prospect discovery included. Free to try. From $19/month when you scale.
ProspectFlow is built for the same job as Lemlist — run personalised cold-email campaigns at scale without burning your sender reputation — with two opinionated differences. First, prospect discovery is built in (you describe the ICP, the AI finds the leads). Second, the free tier sends real emails, so you can verify the playbook works for your audience before paying anyone.

Why founders switch from Lemlist to ProspectFlow
Find prospects, don't import them.
Describe your ICP in plain English. The AI scans the web, extracts verified contact emails, and only keeps deduplicated matches on the right domains.
Start free, scale when ready.
Lemlist's cheapest paid plan starts around $69/mo. ProspectFlow's free tier covers 50 emails so you can prove the model before committing.
Your domain, your reputation.
Send through your own SMTP from day one. We don't shape your sender reputation through a shared pool — the gains and the risks stay yours.
Frequently asked
Is ProspectFlow really a drop-in Lemlist alternative?
For the core loop — find prospects, write personalised AI emails, send via SMTP, track engagement, capture replies — yes. We focus on that workflow, not on adding peripheral tools.
Can I import my existing Lemlist prospect lists?
Yes. Export a CSV from Lemlist and import it through Prospects → Add prospects → Upload CSV.
How is the AI prospect finder different from buying a list?
It searches the live web for companies matching your ICP description, extracts the contact emails published on their own websites (about, team, contact pages), and validates the domain. No purchased database — no stale or fake addresses.
Does ProspectFlow handle deliverability for me?
You bring your SMTP and your domain (with SPF, DKIM, DMARC). ProspectFlow paces sends, rotates SMTP accounts on paid plans, injects required compliance headers (List-Unsubscribe), and tracks bounces and replies — but the warmup and domain reputation stay yours.
What happens to my data if I cancel?
Prospects, campaigns and statistics remain available until you delete them. We never resell or share your prospect data — it's yours.
