Summary

Twilio SendGrid processes over 50 billion emails every month, making it imperative to protect recipients' information from phishing attacks. The company measures its success in preventing malicious email through its Inbox Protection Rate, which stands at 99.97% as of March 31, 2019. To achieve this, Twilio SendGrid uses machine learning technology called Phisherman, trained on vast amounts of data to identify patterns in abusive email content and flag suspicious emails. The company's Compliance Agents review caught phish to refine the system and prevent false positives from affecting legitimate senders. With its massive scale comes a responsibility to increase transparency around security measures and data usage, setting thresholds for industry-wide standards.
