i created this last summer
(test just email gpt@franzai.com)
sadly it never took off so it just became another abandoned side project
but still sometimes I use it ie do distill long emails or translate them without leaving the inbox - also the reminder and todo list feature is nice - whereby i mostly use the "remind me of this email next monday"
so my learnings for email agents: give them a sense of time and memory. its not only about that you write an email and send it but also when to write whom
Sorry for plugging in our product here but this comment seemed relevant. We are actually building something similar at mxgo[.]ai. Started exactly same way as you did, now working on a chrome extension with suggestions within inbox. Would love to connect and know your feedback.
Very cool! We’ve seen some neat personal assistants built with AgentMail as well
