Instead of forwarding to an email address, KaiMail can POST incoming messages as a signed JSON payload to a URL you provide.
This lets your application receive and process email directly without routing it through a personal inbox.
Why would I use webhook delivery instead of email forwarding?
Webhook delivery enables real-time, automated processing of incoming emails. Instead of manually checking an inbox or building complex mail polling logic, your application receives emails instantly as structured JSON. This eliminates inbox clutter, reduces latency, and lets you programmatically extract data, trigger workflows, or store messages directly in your own database.
What problems does webhook delivery solve?
- Inbox overload: Prevent automated emails (order confirmations, support requests, alerts) from overwhelming personal or team inboxes
- Manual processing: Eliminate error-prone, slow human handling of routine email-based tasks
- Integration gaps: Bridge email with modern systems (CRMs, ticketing tools, databases) without proprietary connectors
- Polling inefficiency: Avoid the complexity and delay of repeatedly checking an IMAP inbox
- Security concerns: Signed payloads ensure emails come from KaiMail, unlike forwarding which can trigger SPF/DKIM failures
Who is webhook delivery best suited for?
Developers and technical teams building:
- Support ticket systems that convert emails into tickets
- E-commerce platforms processing order/shipping notifications
- DevOps alert pipelines routing monitoring emails to Slack/PagerDuty
- SaaS applications with email-based user interactions
- Data extraction pipelines that parse structured data from emails
- Custom CRM or ERP integrations requiring email ingestion
What are common use cases?
- Creating support tickets from emails automatically
- Parsing order confirmations into your order management system
- Archiving emails in cloud storage or databases
- Triggering CI/CD pipelines from email alerts
- Validating user email addresses via inbound authentication tokens
- Building email-based automation workflows without maintaining a mail server
- Training Large Language Models (LLM)
