Recipient suggestions
The To field already knows.

Start typing and the people from your own threads are offered, ranked by how often and how recently they turn up. Nothing to import first.

In short

What is recipient autocomplete?

Recipient autocomplete offers matching people as you type an address, so you pick a name instead of spelling one out. Mail apps build that list from an address book, from mail already exchanged, or from both.

How it works

Ranked by habit, not alphabet

The closest match to what you type comes first, then whoever turns up in the most threads, then the most recent. Names and addresses both match.

A book that fills itself

Send to somebody and they are added to Contacts in the sidebar, which is offered above the names read from your threads.

One book for the workspace

What anybody saves, everybody sees, and the API and the MCP server read and write the same rows. Audiences sort the book into named lists.

Scopes for the contact book

Give an API key only the ones it needs.

contacts:readlist and look upcontacts:writesave, edit, removeaudiences:readlist audiencesaudiences:writecreate and fill them

Good practice

Getting the most out of it

  1. 01

    Save for the team

    Names read from threads are offered to the workspace owner only, so save anybody colleagues need to reach.

  2. 02

    Keep one-off senders

    Somebody who has only written to you drops out after 100 newer threads unless you save them.

  3. 03

    Type the domain

    Addresses match too, so typing acme offers the people at acme.com.

Where it stands
