The agent pulls from your CRM, enrichment providers, and intent data to build segments that go beyond basic firmographic slices. A segment might be 'companies with 100–300 employees, Salesforce stack, no current enrichment tool, intent spike in the last 14 days' — a group of 87 accounts that share a specific situation. Each segment is defined by 4–8 attributes, verified against live data, and sized before campaign build begins. Segments built this way produce 2–3× higher engagement than broad firmographic sends.

The copy isn't generic. The agent writes subject lines, email bodies, and CTAs that reference the attributes that define the segment: the specific tool stack they're on, the intent signal that triggered their inclusion, the lifecycle stage they're in. Each campaign has a 3–5 email sequence with spaced timing, varied angles, and escalating personalization. Email 1 opens with the situation. Email 2 leads with proof. Email 3 is a direct ask. Email 4 is a light break-up. The structure is built to maximize replies across the window, not burn the list on email 1.

Sending a campaign is the easy part. Managing it is where most teams lose performance. The agent handles send time optimization (per-contact, not broadcast time), bounce management (hard and soft), unsubscribe suppression, and deliverability monitoring — open rates, spam rate, domain reputation. Contacts that reply are automatically paused from the sequence. Contacts that don't open 3+ emails are moved to a lower-frequency nurture segment. The list isn't burned by the campaign — it's maintained as a healthy, deliverable asset.

Every campaign run generates a performance report that breaks down results by segment, email step, subject line variant, and contact segment — not just aggregate open and reply rates. The report identifies which email in the sequence drove the most replies, which subject line variant outperformed, and which contact attributes correlated with higher engagement. These inputs feed the next campaign: better segments, better-calibrated copy, and a shorter path to the reply rate the team needs.
