Our verdict

The cold email infrastructure choice when deliverability and inbox scale are the bottleneck on your outbound program. Worth using if you're sending thousands of emails a day across many inboxes and need warmup, AI personalisation, and unified reply management in one platform.

Best for: Outbound agencies, B2B SDR teams, and operators running cold email at thousands-per-day volume who need deliverability as a first-class feature.

Pros

• Strong deliverability infrastructure with automated warm-up across inboxes
• Unified inbox and AI reply categorisation handle scale without losing context
• Built-in B2B lead database removes one tool from the outbound stack

Cons

• Cold email regulatory landscape is tightening, worth monitoring
• Pricing scales with inboxes and contact volume
