Email Automation with OpenClaw: Corporate Mail Integration
Every day, your support team receives hundreds of emails: 80% are routine queries (order status, payment details, FAQ), 15% require urgent resolution, and 5% are spam. Without automation, employees spend up to 40% of their time sorting and crafting repetitive replies. We at OpenClaw know how to tame this chaos. Our platform integrates with your corporate mail system, taking over classification, routing, auto-replies, and attachment processing. We customize classifiers for your unique business processes, achieving 97% accuracy. Result: response time for typical requests drops 2–3x, support load decreases by 60%, and operational cost savings can exceed $200,000 annually for a mid-size team. These numbers come from real projects handling over 5,000 emails daily.
How OpenClaw Processes Emails in Real-Time
We use the most suitable protocol for each mail system:
- Google Workspace (Gmail): Gmail API for read/send, Google Pub/Sub for push notifications. Authentication via OAuth 2.0 with minimal scopes.
- Microsoft 365 (Outlook/Exchange): Microsoft Graph API and Exchange Web Services. For on-premise Exchange, we use EWS. Hybrid configurations are supported.
- IMAP/SMTP: Universal method for any mail server — Yandex.Mail, Mail.ru, corporate solutions. We use IMAP IDLE for near-real-time (latency under 1 second).
| System | Protocol | Authentication | Features |
|---|---|---|---|
| Google Workspace | Gmail API + Pub/Sub | OAuth 2.0 | Push notifications, label support |
| Microsoft 365 | Graph API + EWS | OAuth 2.0 / NTLM | On-premise Exchange, delegation |
| Other IMAP/SMTP | IMAP IDLE | Password / OAuth | Universality, polling |
What Automation Delivers: Manual vs. Automated
| Parameter | Manual Processing | OpenClaw Automation |
|---|---|---|
| Time per typical request | 5–10 minutes | 10–30 seconds |
| Routing accuracy | 70% (errors) | 95%+ |
| Attachment handling | Manual, up to 3 min | Automatic, 5 seconds |
| Support load | 100% manual | Reduced by 60% |
Automation with OpenClaw is 3x faster than manual processing and 2x more accurate.
Why Choose Email Automation?
Manual email processing leads to errors, delays, and employee overload. OpenClaw solves three key problems:
- Classification and routing: Each email undergoes NLP classification (topic, tone, urgency, language) and is assigned to the responsible department with a CRM tag. Accuracy exceeds 95% on typical queries.
- Auto-replies: For recurring questions (order status, payment details), the agent replies instantly; for non-standard ones, it drafts a response with suggested actions.
- Attachment processing: Data from PDF/DOCX invoices, contracts, and reports is extracted (payee, dates, amounts) and automatically fills CRM forms or writes to ERP.
- Summarization: Long email threads are compressed into a concise summary with action items.
A Real-World Case: Retail Client with 7,000 Emails/Day
One of our clients, a mid-size e-commerce company, received 7,000 emails daily. Their support team of 10 was overwhelmed. We integrated OpenClaw with their Google Workspace, configured classifiers for order, refund, and shipping queries, and built auto-reply templates for common questions. After deployment, average response time dropped from 8 minutes to 2 minutes, and the team could handle 3x the volume without adding headcount. Support costs fell by 55%, and customer satisfaction scores improved by 20%. The LLM-based summarization reduced ticket escalation time by 40%.
How to Integrate in 6 Steps
- Process audit — analyze typical emails, identify recurring scenarios.
- Design — configure classifiers, response templates, routing rules.
- Integration — connect your mail system, set up OAuth/tokens, deploy connectors.
- Testing — run 100+ test emails, measure latency p50/p99.
- Deploy — go-live, set up monitoring and audit log.
- Documentation and training — hand over instructions for admins and operators, 1 month warranty support.
Security
We use minimal necessary OAuth scopes; all actions are logged in a centralized audit log. PII data is masked before sending to cloud LLMs. For sensitive environments, we offer on-premise deployment with model isolation.
More about security and auditing
All email actions are logged in a centralized audit log. Access to data is role-based. TLS 1.3 encryption is used during transmission. Before processing with LLMs, data is anonymized: names, phones, emails are replaced with pseudonyms.Timelines and How to Start
Typical integration takes 2–3 weeks turnkey. For complex customizations (non-standard fields, legacy systems), up to 6 weeks. Contact us for an audit and cost estimate — we calculate individually. Get a consultation: we will explain how OpenClaw fits into your infrastructure.
We bring 5 years of experience in NLP and MLOps, having delivered 15+ email automation projects for companies from 50 to 5,000 employees. Technologies we rely on: OAuth 2.0, Microsoft Graph API.
