Inbox triage (free)

No Superhuman. Just Gmail + Claude in a side window.

If you can't justify Superhuman yet, Gmail's filters + canned responses + a Claude side window covers 80% of the value. Two filters do the splits Superhuman charges for.

Workflow
  1. 1
    Set up 3 filtersGmail

    Gmail filters: VIP (named senders), Newsletters (list-unsubscribe header present), Action (you're in To, not CC). Triage in that order.

  2. 2
    Drafts in side windowClaude

    Claude in a browser tab. Pinned. Paste email + 3 of your past replies for voice; paste draft back into Gmail.

    Prompt · Reply draft (same prompt as Superhuman version)
    Draft a reply to this email in my voice.
    
    Email I received:
    """
    {{paste email}}
    """
    
    3 of my recent replies (for voice anchoring):
    """
    {{paste 3 replies}}
    """
    
    Intent: {{e.g. "decline politely", "say yes and propose Tue 2pm", "ask one clarifying question"}}.
    
    Constraints:
    - Length: same as my voice samples, no longer.
    - No "Thanks for reaching out" or "I hope you're well".
    - One specific reference to something they said.
    - One clear next step.
    - Sign off the way I sign off in the samples.
    
    Output the reply only.

    Schedule sends manuallyGmail

    Gmail's Schedule send (the small caret next to Send). Send between 7 to 9am local for higher reply rates.

What it produced
Indie consultant, 90 emails/day

From 60 min/day on email to 35 min/day. Tested Superhuman at month 3, kept the pipeline; the only gap was raw keyboard speed.

Common pitfalls
Filter rot

Gmail filters are write-once-forget. Re-audit every 2 months or you'll find the VIP filter quietly missed your top customer.

Tab-switching tax

Without Superhuman's keyboard composition, every reply costs you the Cmd+Tab. If your inbox crosses 200 emails/day, that tax compounds. Upgrade then.
