Fluxmail vs Cora
Cora screens your Gmail and summarizes the overflow into twice-daily briefs, while you keep reading and writing in Gmail. Fluxmail replaces the client itself with a fast AI inbox that triages in real time.
No credit card required. Cancel anytime.
A full email client
Fluxmail is where you read, write, and search your mail. Cora works behind Gmail; you still live in Gmail.
Real-time, not twice a day
Fluxmail triages every message as it arrives, with a priority queue. Cora batches the overflow into two daily briefs.
More AI for less
Every Fluxmail feature is $12.50/month billed annually, with 5 accounts. Cora's $20/month plan covers 2 accounts.
