Plans meter tokens and email volume. Lite gives 2,000 tokens and 5,000 emails a month on 10 warmed accounts, so heavy senders move up fast.

What we noted

Tokens limit reveals and AI use
Lite caps email at 5,000 a month
Enterprise pricing is custom

Not the right fit for

Teams that only need email verification
High-volume senders who want flat pricing

What each one does differently

Instantly

$47/mo Free trial MCP API

Why it comes up: Cold email and warm-up if you already have a lead list.

Watch out: Deliverability still depends on your domains and inboxes, not the tool alone.

Best for

Outbound recruiting teams sending at volume
Agencies running many sending accounts
Desks that need warmup plus a unibox
