Could you build this?
Partial Building a basic AI draft generator is easy, but integrating full mail sync across IMAP/Gmail/Exchange protocols, maintaining an open-source Thunderbird extension (XPCOM/MailExtensions), and handling iOS mail client sync reliably requires significant email protocol engineering.
What it would actually take: The product consists of a cross-platform backend communicating via IMAP/SMTP/JMAP and OAuth2, an iOS native mail client, and a Mozilla Thunderbird MailExtension add-on. The hardest elements are robust bidirectional email synchronization, handling diverse MIME formats and broken email headers across providers, and maintaining strict zero-retention ephemeral LLM pipelines while adhering to Thunderbird extension APIs and iOS background fetch constraints.
