The Importance of Email Validation

Capturing user emails is a fundamental function of chatbots. Whether you’re building a customer support chatbot, a sales support system, or an FAQ assistant, obtaining valid email addresses is essential for follow-up communication and automation. However, ensuring the accuracy and validity of the captured emails is not always straightforward.

Current VoiceFlow Email Capture Options and Their Limitations

Let’s take a look at some common approaches to email validation in chatbots:

  1. No Validation: Simply capturing the entire user reply without any validation can lead to inconsistent and unreliable email data.
  2. Voiceflow Entities: While Voiceflow provides an entity system to identify email addresses, it has limitations. If the user’s input doesn’t match the expected format, the extracted email may be incomplete or invalid.
  3. AI-based Validation: Using AI models like GPT to extract email addresses from user replies can be effective, but it still struggles with edge cases and incomplete email formats.
  4. JavaScript String Manipulation: Utilizing regular expressions in JavaScript to validate email patterns is a step in the right direction. It can filter out obviously invalid emails, but it doesn’t guarantee the existence of the email address.

Introducing Umbral Email Validator

To address these challenges, we’ve developed Email Validator – a comprehensive solution for foolproof email validation in chatbots. Email Validator combines the power of regular expressions with the robustness of a third-party email validation service called ZeroBounce.

How Email Validator Works

  1. Obvious Email Check: Email Validator first applies a regular expression to the user’s input to identify potential email addresses. This step filters out obviously invalid formats.
  2. ZeroBounce API Integration: If the input passes the obvious email check, Email Validator sends a request to the ZeroBounce API. ZeroBounce verifies the existence of the email address by checking the DNS server records of the email provider.
  3. Validation Result: ZeroBounce returns a status indicating whether the email address is valid or not. If it’s valid, Email Validator marks the email as validated for future use in automations. If it’s invalid, the chatbot prompts the user to provide a correct email address.

Benefits

  • Ensures the accuracy and validity of captured email addresses
  • Reduces the risk of email bounces and protects your email sending reputation
  • Seamlessly integrates with your chatbot flow
