Cold email sending & deliverability

Flowfiy vs Instantly

Instantly is a cold-email sending and deliverability tool (mailbox rotation and warmup) — it assumes you already have a list. Flowfiy is an AI sales engine: it finds real businesses on Google Maps and a B2B people database, researches and qualifies each one by how much it needs your service, then writes the emails.

Instantly is built for sending volume: it rotates inboxes, warms them up, and helps cold email land. But it assumes you already have a list and copy — it doesn't find leads, research them, or score how much each one needs what you sell.

With Flowfiy you describe the leads you want in plain English; it finds matching businesses on Google Maps and a B2B people database, researches each one, scores it 0–100 by how much it needs your service, and writes a personalized email per lead — then sends from your own Gmail after review.
