Instantly
Stands out: Warmup, unibox, and volume send with hosted MCP and a public API.
Watch out: Deliverability still depends on your domains and inboxes, not the tool alone.
Not the right fit for
- Teams that only need LinkedIn messaging
- Buyers looking for an ATS
Unify
Stands out: A real free plan plus Unify MCP that runs the same agent as Unify Chat, billed on the same credits.
Watch out: HubSpot and Salesforce sync is read-only on Pro. Write-back, the dialer, website intent, and the open API are on annual Business. Phone lookups average 4 credits.
Not the right fit for
- Teams that need Salesforce write-back on a $20 seat
- Buyers who want a native ATS, not outbound GTM
