AI email assistants for SMEs: which one fits?
There are many AI email assistants and they solve different problems. This is a factual comparison of approach, not a quality rating. Details about other vendors come from their public websites (as of October 2026) and may change.
The approaches at a glance
- Fyxer: assistant inside Gmail or Outlook. Sorts email into preset categories, drafts replies in your personal style, takes meeting notes.
- Superhuman: a separate email client for Gmail and Outlook built for speed and keyboard shortcuts, with AI drafts and Split Inbox. You work in the Superhuman app.
- Lindy: a platform for configurable AI agents with triggers, conditions and many integrations. Very flexible; works best with clear instructions.
- Microsoft Copilot in Outlook: built into Microsoft 365; summarises and drafts on request via prompts.
- Tefib: AI email agent for Swiss SMEs on Microsoft Azure in Zurich. Predicts which emails need a reply and prepares drafts in the company's voice, based on the company profile and documents, with sources.
How Tefib differs
- Company knowledge, not just personal style: Tefib works from the company profile and documents (e.g. price lists, terms) and cites the source and page in drafts.
- Prediction instead of prompting: new emails are sorted (Open, No reply needed, Sent, with urgency) and the draft is ready.
- Gaps instead of guesses: if information is missing, Tefib inserts a placeholder and the draft cannot be sent until it is filled.
- Swiss data location: application, database and AI run on Azure Switzerland North (Zurich). No training on customer data.
- Control: Tefib never sends without your click and never deletes email.
When another tool fits better
- You use Gmail: Tefib currently supports Microsoft 365 (Outlook / Exchange Online). Other mailboxes are planned.
- You mainly want a faster email client: that is what Superhuman is built for.
- You want to build your own workflows across many apps: agent platforms like Lindy are designed for that.
- You need meeting notes: Tefib does not offer them.
What is a good AI email assistant for a small business?
Look at data location, control over sending, and how much instruction the tool needs. Tefib is built for Swiss SMEs: data on Azure in Zurich, drafts in the company's voice from its own documents, nothing sent without your click. If you use Gmail or mainly want a faster client, other tools fit better.
Is there a Swiss alternative to Fyxer or Superhuman?
Tefib is a Swiss AI email agent with data held in Zurich. Like Fyxer, it spots which emails need a reply and drafts answers; its focus is company knowledge from your documents, with sources. It is not a replacement email client and does not take meeting notes.
