How It Works
Get up and running in three simple steps
Set a Goal & Add Actions
Create a campaign with a clear goal — like booking demos or collecting payments. Then give your AI the actions it needs: send emails, schedule meetings, or trigger webhooks.
Import Contacts & Launch
Upload your contact list, set a schedule, and go live. AI calls and emails each contact, pursuing the campaign goal and taking action in real time.
Track Results & Outcomes
See which goals were achieved, listen to recordings, read AI summaries, and review every action taken. AI handles follow-ups automatically.
Campaigns With Goals and Actions
Define what you want to achieve. Give AI the tools to make it happen.
Goal-Driven Campaigns
Every campaign starts with a goal — collect a payment, confirm an appointment, qualify a lead. AI pursues the goal across calls and emails until it's achieved.
Send Emails Mid-Conversation
AI sends follow-up emails, confirmations, or documents during or after a call. No manual steps — the agent handles it as part of the conversation.
Schedule Meetings Automatically
AI books meetings on your calendar in real time. Customers confirm a time on the call and get a calendar invite instantly.
Trigger Any API or Webhook
Connect Phone Stack to your systems. AI can trigger webhooks to update your CRM, create tickets, process payments, or kick off any workflow.
Compliance Built In
Consent tracking, opt-out handling, AI disclosure, and full audit trails. Built for compliant outreach from day one.
Per-Minute + Per-Email Pricing
Pay for talk time and email sends. No contracts, no per-seat fees, no hidden charges.
One Platform, Every Outbound Use Case
Set the goal. Assign the actions. Let AI run the campaign.
Customer Support Outreach
Goal: resolve issues before they escalate. AI calls customers, answers questions, and sends confirmation emails or schedules follow-up meetings automatically.
Service & Operations
Goal: keep customers informed. AI handles delivery updates, scheduling changes, and status notifications — triggering webhooks to update your systems in real time.
Billing & Collections
Goal: collect payments. AI follows up on overdue invoices by call and email, sends payment links, and logs outcomes via API to your billing system.
Sales & Re-engagement
Goal: book meetings and qualify leads. AI calls opted-in contacts, schedules demos on your calendar, and sends follow-up emails — all within compliance guardrails.

Sample Transcript
AI: Hi, this is Sarah from Acme Services. I'm calling about your account — we noticed your payment from March is still outstanding. Do you have a moment to go over it?
Customer: Oh right, I forgot about that. Can you tell me the amount?
AI: Of course! The balance is $247.50 from your March invoice. I can help you set up a payment right now, or schedule a reminder for later this week. What works best?
