Why API-first

Outreach as a feature of your product.

No dashboard required

REST API + webhooks. Integrate outreach sequences into your SaaS, workflow, or script in an afternoon.

Bring your own SMTP

Use SMTP2GO, Postmark, Gmail, or any SMTP provider. Keep full control over sender reputation.

Cross-campaign dedup

Group campaigns into an Outreach and guarantee each contact only gets enrolled once across the whole effort.

No per-seat tax

Usage-based pricing. Add teammates without watching the bill triple.

Get early access.
