The Mailshake alternative built AI-first, not template-first.
AI prospect discovery, smart personalisation, RFC 8058 compliance — all in the same flow. Bring your own SMTP. Flat pricing from $29/mo.
Mailshake comes from the template-and-merge-tag era; AI was added later as a feature. ProspectFlow is AI-first end to end: the prospect list is generated from your ICP description, every email is personalised per-recipient before send, and the compliance headers receivers require are on by default. Same job, a more modern stack.

Why founders switch from Mailshake to ProspectFlow
Modern AI workflow, not 2018 templates.
Mailshake started as a template-and-merge-tag tool and AI was bolted on later. ProspectFlow is AI-first: describe your ICP, the AI finds the prospects on the live web, AI drafts a personalised email per contact, and you ship after a final review.
Pay once for the team, not per seat.
Mailshake's pricing is per user. ProspectFlow is one flat monthly price — the second person on the team is free.
Compliance built in, not an afterthought.
Every ProspectFlow send ships the RFC 8058 one-click unsubscribe headers Gmail and Yahoo now require, plus tenant-wide opt-out honoring. You don't think about it — it's just on.
Frequently asked
Is ProspectFlow a drop-in Mailshake replacement?
For the core cold-email workflow — find prospects, write personalised emails, send via SMTP, track engagement, capture replies — yes. The conceptual model is similar; the AI prospect discovery is genuinely new, and the flat pricing is significantly cheaper for any team beyond one person.
Can I import my Mailshake lists?
Yes. Export to CSV from Mailshake → import via Prospects → Add prospects → Upload CSV. Custom fields carry over; templates need to be re-saved by hand in the templates page.
Does ProspectFlow have a Chrome extension like Mailshake?
Not yet. The workflow goes the other way — describe the ICP and let the AI find prospects, rather than picking them off LinkedIn one at a time. If LinkedIn-first prospecting is your primary motion, Mailshake's extension is closer to that workflow.
Do you support multi-step campaigns?
Yes. The campaign wizard supports an initial send + automated follow-ups, with replies auto-pausing the sequence per recipient.
What about deliverability?
We pace sends with jittered 30-120s delays per SMTP, enforce daily limits, ship the RFC 8058 unsubscribe stack, and parse bounces from IMAP to flag dead addresses. Domain-level setup (SPF, DKIM, DMARC) stays with you — see our deliverability guide.
