Grok Bot inboxes add plus-address email aliases that can trigger routines
Grok Bot now supports plus aliases on its email addresses, per Sam Sokolin, who builds Grok Bot: a bot can send and receive mail at plus-address aliases of its own address (a +receipts tag, for example), and routines can be set to run only for mail sent to a specific alias. The announcement image shows example aliases for newsletters, receipts, signups and travel.
How you’d use it: Give receipts or signups their own alias so one routine handles only those.
