Where they pull apart

Instantly

Stands out: Warmup, unibox, and volume send with hosted MCP and a public API, plus an AI Recruiting Agent that finds candidates from a job link and emails them.

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

OutboundSync

Stands out: API, webhooks, and agent skills ship on every plan, with unlimited connectors and SOC 2 Type II.

Watch out: You are billed on sent messages, not replies or opens. Staying over plan plus 2x rollover can pause sync. Annual pre-pay is two months free.

Not the right fit for

  • In-house teams that already log sends natively
  • Very high volume unless you buy Custom
