Cold vs warm outreach are different motions with different conversion expectations. Cold: 1-3 meetings per 100 sent. Warm: 5-15 per 100. Both are valuable but need different cadences and metrics. Artra at $59-$99/month runs both motions in parallel from the same agent infrastructure.
Cold vs warm side-by-side
| Dimension | Cold outreach | Warm outreach |
|---|---|---|
| Prior relationship | None | Some — customer, lead, attendee, referral |
| Reply rate | 1-5% | 10-30% |
| Positive reply rate | 0.5-2% | 5-15% |
| Meetings/100 sent | 1-3 | 5-15 |
| Cadence length | 6-12 touches over 30-60 days | 3-5 touches over 14-21 days |
| Tone | Establishing relevance | Reactivating relationship |
| Personalization basis | External research signals | Prior interaction history |
| Use case examples | Net-new pipeline, new ICP | Event leads, re-engagement, expansion |
Pipeline strategy: combining cold and warm
- Cold: generates net-new awareness and pipeline.
- Content/event/inbound: creates warm prospect inventory.
- Warm follow-up: converts warm inventory at high rates.
- Re-engagement: revives cold prospects that engaged in the past.
- Expansion: grows existing customers with the same agent infra.
Most teams optimize for warm conversion because it's the highest-ROI segment but maintain cold pipeline as the long-term feeder.

Frequently asked questions
What's the difference between cold and warm outreach?
Cold outreach targets prospects with no prior relationship to your company — pure cold outbound. Warm outreach targets prospects with some prior connection: existing customers, demo no-shows, closed-lost deals, content downloaders, event attendees, referrals, or prior conversations. Warm outreach converts 3-5x higher than cold because of prior context. AI SDRs like Artra handle both with different sequence configurations.
When should I use cold vs warm outreach?
Use cold outreach when: building net-new pipeline, entering new market segments, or scaling beyond your warm pipeline capacity. Use warm outreach when: you have existing prospect lists (event leads, downloads, demo no-shows), running expansion or re-engagement campaigns, or following up on referrals. Most teams run both in parallel — cold for top-of-funnel, warm for higher-conversion compounding pipeline.
What conversion rates should I expect?
Typical conversion rates in 2026: Cold outreach 1-5% reply rate, 0.5-2% positive reply rate, 1-3 meetings per 100 sent. Warm outreach 10-30% reply rate, 5-15% positive reply rate, 5-15 meetings per 100 sent. The gap reflects prior context: warm prospects know who you are; cold prospects don't. Both are valuable but the metrics shouldn't be compared apples-to-apples.
How do AI SDR cadences differ for cold vs warm?
Cold AI SDR cadences: 6-12 touches over 30-60 days, signal-driven personalization, focus on establishing relevance. Warm AI SDR cadences: 3-5 touches over 14-21 days, reference prior interaction, shorter and more direct CTAs. Cold needs to introduce; warm needs to reactivate. Both use the same AI agent infrastructure but with different sequence templates and timing.
Can AI SDR run cold and warm in parallel?
Yes — most teams run cold and warm AI SDR campaigns in parallel. In Artra, this is typically configured as: cold cadence on one prospect segment (e.g., new ICP targets), warm cadence on another (e.g., existing customers, event leads). Each has its own sequence, voice, and metrics. CRM segmentation determines which prospect flows into which cadence.
