myHermy vs Postfleet

myHermy and Postfleet are both productivity tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

myHermy

The core workflow is deliberate: you bring your existing ChatGPT, Claude, Copilot, or Grok subscription, myHermy provisions a dedicated server in one of 30-plus regions, and your agent starts handling email triage, calendar checks, research, and reminders across WhatsApp, Telegram, Discord, Slack, Signal, and email. Daily automated backups with seven-day retention and one-click restore mean a bad config doesn't cost you a week of history. Root SSH and a browser terminal are available if you need to dig in — but the dashboard is built for people who never want to. Where this hits a wall: there is no API, so teams that need to pipe agent output into their own systems or trigger the agent programmatically from external events have no supported path.

Postfleet

The pipeline runs SPF/DKIM/DMARC authentication, strips tracking pixels and reply chains, removes hidden text and homoglyphs with a logged sanitization report, gates on malware and spam verdicts, then runs an injection scan before extraction ever touches your schema. Injection-risk mail is retained without extraction — it never reaches your agent. Clean mail becomes typed JSON with a confidence score in roughly eight seconds from external send to webhook delivery, per vendor-measured production data. Both hosted MCP and a local npx package are documented, and the same six tools work across Claude, Cursor, Windsurf, and VS Code. Operators can inspect raw versus processed output side by side in the dashboard for every message.

Pros	Bring-your-own LLM subscription support (ChatGPT, Claude, Copilot, Grok), so you avoid paying a second per-message bill on top of hosting — a cost that compounds fast once your agent is running around the clock. Private dedicated server per user, which means your conversations and task history are not co-mingled with other users' data — the failure mode on shared-infrastructure agent platforms. Daily automated backups with seven-day retention and one-click restore, so a broken update or config mistake doesn't permanently lose your agent's context and history. Six-channel reach (Telegram, WhatsApp, Discord, Slack, Signal, and email) from a single agent deployment, so you don't manage separate bots per platform or retrain your habits to use a new interface. Root SSH and browser terminal access on every plan, so users who need to inspect the server environment or install additional tooling aren't blocked by a locked-down hosting layer.	Prompt-injection screening runs before extraction, so attacker-crafted content in an invoice body never reaches your agent's context — without this gate, a hidden instruction in a vendor email can redirect an agent that has tool access to credentials or external APIs. Every sanitization action is logged in a readable report per message, which means when a malformed email causes unexpected agent behavior, you have a record of exactly what was stripped and why — not a black box. Fail-closed on malware and spam by default, so a misconfigured pipeline does not silently pass bad payloads; quarantined messages are held for operator reclassification rather than dropped or forwarded. Both hosted MCP and local npx paths are documented with the same six tools and the same API key, so development and production environments stay symmetric without a separate self-hosted deployment process. Schema-based extraction delivers typed JSON with a confidence score to your webhook, which means downstream code parses a known shape rather than writing a new email body parser for each sender's format.
Cons	No API is available, which means any external system — a CRM, a webhook, a custom dashboard — cannot programmatically trigger the agent or receive structured output from it. Teams that need agent actions to feed into their own product or internal tooling have no supported path and need to switch to an API-first agent platform. No self-hosted option exists, so organizations with data residency requirements or policies that prohibit third-party cloud hosting cannot use the service regardless of the private-server framing — the infrastructure is still provisioned and managed by myHermy. The agent's capabilities are bounded by the Hermes Agent and OpenClaw implementations; there is no documented way to swap in a custom agent framework or extend the agent's core logic beyond what the dashboard exposes. Teams with specialized workflows that outgrow the built-in capabilities — email, calendar, research, reminders — have no upgrade path within the platform.	Injection-flagged mail is quarantined without extraction — there is no configurable threshold or secondary routing path. Teams that need to process flagged messages with a human review step before agent handoff have to build that queue themselves outside the pipeline, and the two systems then need to stay in sync. The extraction schema is applied uniformly per pipeline configuration; the docs do not describe per-sender or per-classification schema switching. Teams ingesting structurally different document types — invoices alongside shipping notices alongside support tickets — either run separate pipelines per type or post-process the JSON themselves, which grows the integration surface. When a team's volume exceeds the free tier's message quota and the next pricing gate is paid-only, there is no documented rate-limit grace period or overflow queue — requests that exceed quota behavior is not described on the public page, which is a production risk to validate before committing the architecture.

Bottom line

Only Postfleet exposes a public API. Choose based on which difference matters most for your workflow.
