🤖 9 Autonomous AI Agents Built In

AI Agents That Run Your
Entire Email Operation

LeadsFire isn't another template builder with "AI" slapped on it. It's an email platform with 9 autonomous agents that write your copy, warm your domains, optimize send times, run A/B tests, manage deliverability, and set up entire brands — while you talk to it like a teammate.

9 AI agents working around the clock

Each agent runs autonomously on a schedule — monitoring, optimizing, and protecting your email operation without you lifting a finger.

🔥
Throttle Agent
Runs every 30 min

Analyzes deliverability metrics per domain and automatically adjusts send rates. If Gmail starts soft-bouncing, it throttles back before your reputation takes a hit.

Send Time Agent
Runs every 2 hours

Studies when each contact actually opens emails and shifts scheduled sends to their preferred hour. Contacts with 3+ opens get personalized send windows.

🧪
A/B Test Agent
Runs every 60 min

Monitors running A/B tests and picks winners using statistical analysis — or calls the AI for a judgment when the data is ambiguous. Fully automated winner selection.

📈
Warmup Agent
Runs every 2 hours

Manages 28-day domain warmup schedules. Gradually ramps volume from 50/day to your target, pausing automatically if bounce rates spike during the ramp.

Trigger Agent
Runs every 5 min

Behavioral automation engine. Fires rules when contacts open, click, or don't engage — automatically queuing follow-up emails, adding to segments, or pausing sequences.

🛡️
Spam Score Agent
On demand

Scans every email for spam triggers before it sends: ALL CAPS subjects, trigger words, image-to-text ratio, link density, missing unsubscribe headers. Catches problems before ISPs do.

👋
Re-engagement Agent
Runs daily

Identifies contacts who haven't opened in 60+ days and marks them disengaged. Uses AI to analyze brand-level engagement rates and recommend re-engagement strategy.

💬
Reply Agent
Runs every 30 min

Detects when contacts reply to your emails and automatically pauses their sequence. Prevents the awkward "we just talked and you're still dripping me" problem.

🏗️
Brand Setup Agent
Chat-triggered

Tell the AI "set up example.com" and this agent orchestrates the entire process: Mailgun domain → Cloudflare DNS records → verification → SMTP credentials → webhook registration → SSL cert. Fully automated.

The full stack, not a toy

Every feature a real email operation needs — visual builder, segmentation, deliverability monitoring, contact management, and a queue processor that actually sends.

🔀 Visual Flow Builder

Drag-and-drop sequence editor built on React Flow. Add triggers, emails, delays, and endpoints. Click any email node to open the full HTML editor with live preview.

  • Trigger → Email → Delay → End node types
  • Monaco code editor for HTML
  • Inline A/B test panel per email
  • Auto-save flow layout positions

🎯 Smart Segmentation

Build dynamic segments with rule-based filters on any contact field or behavior. Smart segments auto-refresh; manual segments give you full control.

  • Filter by custom fields, status, engagement
  • Rule builder: field + operator + value
  • Real-time contact counts
  • Trigger agents can auto-add to segments

📊 Deliverability Dashboard

Per-domain metrics updated hourly: sent, delivered, bounced (hard + soft), complained, opened, clicked. Traffic-light status system flags problems before they escalate.

  • Green / Amber / Red domain health
  • Bounce rate + complaint rate monitoring
  • Per-domain throttle controls
  • 28-day warmup schedule tracking

📬 Send Engine

Queue processor runs every 10 seconds. Mailgun SMTP, merge tags, dynamic content rendering, CAN-SPAM footer auto-injection, open/click tracking, RFC 8058 unsubscribe headers. Everything by the book.

  • Cross-brand frequency capping (4hr)
  • Batch processing (50/cycle)
  • Automatic retry with backoff
  • Suppression list enforcement

📥 Contact Import

CSV upload with built-in data hygiene. Deduplication, email validation, disposable email filtering, role-based address detection, and typo correction — all before a single email sends.

  • Drag-and-drop CSV upload
  • Quality score per import
  • Custom field definitions
  • Contact status lifecycle tracking

🏢 Multi-Brand

Run multiple brands from one account. Each brand gets fully isolated contacts, sequences, sending domains, AI memory, and deliverability metrics. Zero cross-contamination.

  • One-click brand setup via AI agent
  • Per-brand sending domain + SMTP
  • Isolated contact databases
  • Brand-scoped AI chat sessions

Talk to it like ChatGPT.
It controls the whole system.

This isn't a chatbot that generates text and makes you copy-paste. LeadsFire's AI assistant has tool access to your entire email operation — it can query data, create sequences, build segments, set up brands, and queue sends. You approve destructive actions before they execute.

  • list_brands — Query all active brands with contact and email counts
  • create_segment — Build segments from natural language descriptions
  • setup_brand — Trigger full domain provisioning (DNS → SMTP → SSL)
  • get_deliverability — Pull per-domain metrics and health status
  • queue_for_approval — Propose changes that need human sign-off

Agent Mail — Claude Sonnet 4.6
You
Set up newbrand.com and create a 3-email welcome sequence for SaaS trial signups.
Agent Mail
→ setup_brand("newbrand.com") — creating Mailgun domain, DNS records, SMTP credentials...
Brand is live. Mailgun verified, DNS propagated, SMTP working. I've created a 3-email welcome sequence: Email 1 (Day 0): Quick-start guide — gets them to their first win.
Email 2 (Day 2): Feature highlight + case study.
Email 3 (Day 5): Trial expiration CTA with urgency.

Warmup agent is running — starting at 50 sends/day, ramping to 1,000 over 28 days. Want me to add A/B tests on the subject lines?
You
Yes. And segment it so disengaged users get a different email 3.
Agent Mail
→ create_segment("trial_disengaged", rules: [{field: "openedAt", op: "null_for_days", value: 3}])
Done. A/B tests on all 3 subjects (2 variants each). Created "trial_disengaged" segment — contacts with zero opens after 3 days. Email 3 for that segment uses a re-engagement angle instead of the standard CTA. Ready to review in the flow builder.

From zero to sending in 5 minutes

Guided onboarding walks you through every step. Or just tell the AI what you want.
