The Smartlead alternative without per-mailbox upcharges.
Flat monthly pricing. AI prospect finder included. Bring your own SMTP. Free plan with real sending.
Smartlead is great at sending. But the pricing structure — base plan plus per-mailbox plus the lead finder add-on — adds up faster than the headline number suggests. ProspectFlow keeps it flat: one monthly price covers prospect discovery, personalisation, tracking, and reply detection. And you can verify the model with 50 real sends on Free first.

Why founders switch from Smartlead.ai to ProspectFlow
Predictable, flat pricing.
Smartlead's pricing scales with mailboxes and add-ons. ProspectFlow is one flat monthly price — Starter $19, Pro $49, Ultra $149 — that covers prospect discovery, AI personalisation, tracking, and reply detection.
Prospect finder, not just a sender.
Smartlead's strength is sending; the lead finder is a separate purchase. ProspectFlow's AI prospect discovery is built in on every plan, including Free.
Try with real sends, not a demo.
50 emails on Free with your own SMTP, AI prospect finder, and the full analytics view. Decide based on actual replies, not a sandbox.
Frequently asked
How does ProspectFlow differ from Smartlead.ai for warmup?
Smartlead bundles inbox-to-inbox warmup. ProspectFlow paces sends, rotates SMTPs on paid plans, and enforces daily limits but doesn't run a warmup network yet. For a brand-new cold mailbox we recommend pairing ProspectFlow with a dedicated warmup tool (Mailwarm, Warmup Inbox) for the first 2-4 weeks.
Can I bring multiple SMTP accounts and rotate them?
Yes. Pro includes 3 SMTPs, Ultra includes 10. The queue worker rotates sends across them with daily limits enforced per account.
Where does the AI find prospects?
Gemini generates targeted search queries from your ICP, Tavily Search returns candidate domains, and a custom scraper extracts contact emails from team / about / contact pages on those domains. We never buy or resell databases.
Is there a Smartlead-style master inbox?
Not yet. Replies are detected by the IMAP sync worker and surfaced inside the campaign, but you handle the conversation in your own inbox. A unified inbox is on the roadmap.
How do I migrate from Smartlead?
Export your prospect lists as CSV from Smartlead → import via Prospects → Add prospects → Upload CSV. Templates can be copy-pasted. Campaigns are rebuilt in the new wizard (the sequence model differs, so manual rebuild is cleaner than import).
