email

Most email service providers offer limited visibility into what happens after an email is sent, making it difficult to debug delivery failures and understand the full lifecycle of sent messages.

Single-channel reminder systems fail because clients consume information through different channels (email, SMS, calls, voicemail). Without multi-channel orchestration, reminders are missed and no-show rates remain high (12-18% industry average).

Email providers traditionally only support a single sending region (us-east-1), forcing users with geographically distributed end-users to accept increased latency and slower time-to-inbox regardless of where recipients are located.
