IMAP mailbox (OVH, Orange, host…)? Fyxer is ruled out
If your mail is not hosted by Google or Microsoft, the choice simplifies. Siftbox supports Gmail, Outlook / Microsoft 365, and generic IMAP: create an account, enter your address (password or app password) and your host’s servers. AI triage is read-only and your four folders appear on the IMAP server, visible on all devices. Fyxer works with Gmail or Outlook only: no generic IMAP.

Fyxer connects to Gmail or Outlook (Google-verified, Microsoft-verified). It sorts mail into three buckets: to respond, FYI, marketing. It drafts replies in your style, joins video calls to produce meeting summaries (Meet, Teams, Zoom per their FAQ), and offers scheduling and CRM on the Professional plan. 7-day trial; Starter at $30/month ($22.50 on annual billing), Professional at $50/month ($37.50 on annual billing, August 2026).
Fyxer strengths
- Stays in Gmail or Outlook: no new mail client.
- AI drafts tuned to your history; Fyxer states it does not send mail on your behalf.
- Automatic meeting notes and post-call follow-up.
- Scheduling, Fyxer Chat, and HubSpot on Professional.
- Claimed certifications: ISO 27001, GDPR, SOC 2 Type II (see fyxer.com/security).
Limits or things to watch
- Gmail and Outlook only: no generic IMAP like Siftbox.
- No permanent free tier: 7-day trial, then subscription.
- Three Fyxer categories (respond / FYI / marketing) vs four actionable Siftbox categories.
- Category correction is possible, but no "why" sentence per message like Siftbox.
- Pricing in dollars, UK publisher: verify contract and subprocessors for GDPR.

- Free beta with no card, then €14.99 incl. VAT / month / sorted email account (or €149 / year).
What about drafting? Each tool, its job
Siftbox does not draft your replies: a relevant answer goes through your CRM, client history, and the tools you already use. Siftbox sorts and explains; your AI assistant (Claude, ChatGPT, Cursor) can rely on your already sorted mail once connected, with no built-in drafts in the inbox.
Choose Fyxer if…
- You mainly want AI drafts and meeting summaries.
- You are on Gmail or Outlook and accept a subscription after the trial.
- Your goal is "reply faster", not "see why this is urgent".
Choose Siftbox if…
- You want explainable first-pass triage before opening messages.
- You refuse AI drafting replies on your behalf without relevant context about your work, processes, or clients.
- You want to connect ChatGPT, Claude, or another assistant to your email.
- You need IMAP or an explicit European positioning, with sender rules you control.
