On the surface, Majordomo and CXassist look like the same product. Both promise to read your incoming email and reply automatically, without you in the loop. Both train on your own content. Both let you configure the tone and persona of your agent.
The differences show up when you look closer: which email providers they support, where your data lives, how their pricing scales, and how far the autonomy actually goes.
What CXassist Does
CXassist is an AI email replier with public setup copy focused on Gmail and Outlook. You train it on your documents, URLs, and previously sent emails, then it handles incoming messages — either drafting a reply for your review or sending automatically, depending on mode.
Key features:
- Gmail and Outlook focused — its public product flow emphasizes one-click Gmail and Outlook connections
- Multiple personas — you can configure separate Sales and Support personas and route emails to each based on labels
- Knowledge base training — ingest docs, URLs, and your sent-mail history to calibrate responses
- Draft or auto-send modes — choose whether the agent stages replies for review or fires them directly
- Integrations — connects to Slack, HubSpot, Stripe, and Shopify
- Privacy claim — CXassist states it does not store email content
Pricing: Free trial with 150 emails processed, Starter at $9.99/month with 500 emails processed, Pro at $24.99/month with 3,000 emails processed, and Scale from $299/month. Reviews from the AppSumo community are generally positive, with users frequently citing the Playground feature — a sandbox where you can test how the agent would respond to hypothetical emails before going live — as a practical confidence-builder.
What Majordomo Does
Majordomo is a fully autonomous AI email agent built around IMAP and SMTP. That means it works with any email provider — not just Gmail and Outlook, but any host that exposes a standard inbox: FastMail, Proton Mail (via bridge), corporate Exchange, custom domains, self-hosted servers.
Like CXassist, Majordomo generates replies based on your configured persona and rules. Unlike CXassist, the default is full autonomy with no review queue — the agent reads, decides, and sends.
A few things set Majordomo apart:
- IMAP/SMTP native — connects to any standards-compliant inbox, not just major cloud providers
- Thread-aware — reconstructs full conversation history across inbox and sent folders before generating a reply, so responses are grounded in context, not just the latest message
- Document context injection — dynamically selects relevant documentation URLs based on the incoming email's subject and body, then fetches that content before drafting
- Hosted in Europe — all infrastructure runs in EU data centers; no transatlantic data transfers
- GDPR compliant — DPAs available, right-to-erasure supported, email content processed in-memory and not persisted
- Per-mailbox pricing — agencies can run 20 client inboxes at $9.99/month each, with no per-seat complexity
Pricing: $9.99/month including 500 agent replies. Additional reply packs available. Cancel anytime.
The Deepest Difference: Provider Lock-In
CXassist's public product copy is centered on Gmail and Outlook connections. If your inbox is Google Workspace or Microsoft 365, that's straightforward. But if you're on anything else — Fastmail, a self-hosted Exchange server, a domain hosted by your ISP, or a specialized provider you chose specifically for privacy — CXassist does not document that path as clearly as standards-based IMAP/SMTP setup.
Majordomo speaks IMAP and SMTP. Those are the protocols that underpin essentially all email, regardless of provider. The implication is that Majordomo follows you rather than constraining you to a platform.
For individuals or small businesses on standard Gmail, this distinction doesn't matter much. For agencies managing inboxes across many clients — each with their own mail host — or for any team that's deliberately moved off Google/Microsoft for data-sovereignty reasons, it matters a great deal.
On Privacy
Both tools claim not to store email content. Majordomo's approach goes further: the system is EU-hosted and GDPR compliance isn't marketing language — DPAs are available and the right-to-erasure is actively implemented.
CXassist is a US-based SaaS product. For teams subject to GDPR or sector-specific data regulations, the difference between "we claim not to store it" and a verifiable EU-hosted architecture with DPAs available is meaningful.

Which One Should You Use?
Use CXassist if:
- You're on Gmail or Outlook and have no plans to change
- You want a no-commitment free trial before deciding
- You value the Playground sandbox to test agent behavior before going live
- Slack, HubSpot, or Shopify integration is important to your workflow
Use Majordomo if:
- You need standards-based IMAP/SMTP support rather than a Gmail/Outlook-first product flow
- You're in Europe and GDPR compliance is non-negotiable
- You want full autonomy by default, not as an opt-in mode
- You manage multiple client inboxes and need clean per-mailbox pricing
At the same price point, the choice comes down to who controls the infrastructure and which email providers you need to support. CXassist is the faster path if you're already in the Google/Microsoft ecosystem. Majordomo is the right answer when you need something that works everywhere and you'd rather your email data stay in Europe.
Majordomo is $9.99/month. 500 AI replies included. Works with any IMAP/SMTP inbox. Hosted in the EU.
