Fluxmail vs HEY
HEY is an email service with a @hey.com address and, as of July 2026, no AI features. Fluxmail keeps the Gmail address you already have and adds AI triage, drafting, and an agent on top.
No credit card required. Cancel anytime.
Keep your address
Fluxmail signs into the Gmail you already use. HEY means a new @hey.com address, and your old mail stays behind.
AI where HEY has none
Flux AI triages, summarizes, and drafts. HEY ships no AI drafting, summaries, or triage as of July 2026.
Same care for privacy
Both block spy pixels by default. Fluxmail goes further: email bodies are never stored on its servers.

Which one is right for you?
Best for most people
Choose Fluxmail if…
- You want to keep your Gmail address and your email history; with Fluxmail there is nothing to migrate or forward
- You want AI in your email: automatic triage, drafting in your voice, summaries, and an agent that takes actions. HEY ships none of that
- You want automation that handles mail for you, not a Screener you have to answer for every new sender
- You want a priority queue, tasks from emails, and rules that work while you sleep
- You want the option of monthly billing and a trial before paying for a year
Choose HEY if…
- You want to leave Gmail (and Google) entirely, with a fresh @hey.com or custom-domain address
- You love the Screener's consent-based approach: nobody emails you without your approval
