Send Automated Calls Through Emails API – Trigger Voice Campaigns from Any System

🔑 Key Takeaways:

  • Email as a trigger – Forward an email to a special Robotalker address, and a robocall is sent automatically.
  • No coding required – Use email rules in your CRM or helpdesk to launch voice campaigns without API development.
  • ERP / legacy system friendly – Any system that can send email can now trigger automated calls.

Why Email‑Triggered Robocalls Matter

Not every system has a REST API, and not every team has developers on standby. Yet almost every business application – from legacy ERPs to simple helpdesk ticketing systems – can send an email. Robotalker’s email‑triggered API turns that everyday email into a powerful voice notification engine.

Send an email to a special address, and Robotalker will parse the recipient, the message, and optional parameters, then launch an automated call. It’s the lowest‑friction integration possible.

How the Email API Works

Robotalker assigns you a unique, secret email address (e.g., `campaigns_abc123@trigger.robotalker.com`). Any email sent to that address becomes a call campaign.

Email FieldPurposeExample
To: addressYour unique Robotalker trigger emailcampaigns_abc123@trigger.robotalker.com
Subject lineCaller ID name + optional settings[CALLERID="Maintenance"] Urgent: Boiler inspection
BodyRecipient phone numbers and message text+15551234567, +15559876543||The boiler room needs inspection today.
Attachments (CSV)Bulk recipient listsupload.csv with phone, name, custom fields

Robotalker will parse the email, validate the numbers, convert the message to speech (or use a pre‑recorded audio file if referenced), and start calling.

Step‑by‑Step: Trigger a Call from Your CRM (No Code)

  1. Create an email trigger in Robotalker – Dashboard → API → Email Triggers → Generate new address.
  2. Set default parameters – Choose default voice (male/female), retry settings, time‑of‑day restrictions, and opt‑out behavior.
  3. Configure your CRM automation rule – Example in Salesforce: when a case priority = “High” and case age > 4 hours, send an email to your Robotalker trigger address. Populate the body with the customer’s phone number and a message like “Your support case #1234 requires your immediate attention.”
  4. Test – Send a test email manually. Within 2 minutes, you’ll receive the robocall.

Total setup time: 15 minutes. No developer needed.

⚙️ Advanced: Use Email Headers for Fine Control

Power users can add custom email headers for advanced features:
X-Robotalker-Retries: 3 – override default retry count.
X-Robotalker-Ringless: true – send as ringless voicemail.
X-Robotalker-CallerID: 5551234567 – set outbound caller ID number.

Ideal Use Cases for Email‑Triggered Robocalls

  • IT alerting – Monitoring system sends “server down” email → Robotalker calls on‑call engineer.
  • Customer follow‑up – E‑commerce platform sends abandoned cart email → automated call offering 10% discount.
  • Field service dispatch – Legacy ERP sends “job assigned” email → robot call to technician’s phone with address and work order.
  • Internal approvals – Expense system emails manager for approval → Robotalker calls manager with voice prompt “Press 1 to approve, 2 to deny.”
  • School / community alerts – Mass notification system that only emails can now add voice channel.

Security & Rate Limits

The email trigger includes security safeguards:

  • Sender authentication – You can whitelist approved “from” email addresses. Emails from unknown senders are ignored.
  • Rate caps – Default 60 calls per minute per trigger (adjustable up to 1,000/min on enterprise plans).
  • Audit trail – Every email trigger is logged with timestamp, sender, recipient count, and delivery status.

FAQ: Email‑Triggered Robocalls

HTML emails work fine – Robotalker extracts the plain text version or, if absent, strips HTML tags. Use plain text for best predictability.

Yes, but be mindful of email sending limits. For 10,000+ recipients, we recommend the REST API or CSV upload. The email trigger is ideal for event‑based, real‑time alerts (1–500 calls per trigger).

Robotalker maintains a global opt‑out list. If an email trigger includes an opt‑out number, the system will not call it and will log the attempt. You can export the opt‑out list anytime.
