Frida: a CRM that builds itself from your Outlook email
Frida connects to your Outlook or Microsoft 365 mailbox and runs in its own app. An optional Frida pane inside Outlook, in early access and installed as a custom add-in, shows the deal behind the email you have open and drafts the reply there. It reads your email conversations, detects sales opportunities, and creates and updates deals on a dealboard automatically. It suggests a follow-up when a quote or proposal goes quiet and drafts replies in your own voice. You approve everything; nothing is sent automatically.
- Strength: no data entry. The board builds itself from the conversations you already have.
- Strength: on Personal and Pro you can add knowledge sources, such as price lists, documents or your website, so drafts use your facts.
- Limit: deliberately narrow. Frida is not a marketing platform and not a configurable revenue workspace. Its Outlook pane is in early access and not yet listed in Outlook’s add-in catalogue.

- Want a broad platform your whole company can grow into: look at HubSpot, Zoho CRM, Dynamics 365 Sales or Attio.
- Want the least CRM upkeep: look at tools that capture from email by themselves, such as Salesflare and Frida. Frida also creates the deals and drafts the replies for you to approve.
