Not buried in old chats.

Email

  • Forward contracts, receipts, and attachments to Inbox4.
  • Inbox4 processes and tags each item automatically.
  • Keep one private, searchable archive.

Ready when you need it.

Without digging through mail chains.

Stars

Yes, you can star messages.

The problem starts later.
