Settings: Contacts

Three things live here: how a couple is addressed on letters and labels, the honorific titles you can pick when entering somebody, and the relationship types you use for family members, relatives and yahrtzeits.

Settings → Contacts.

Settings Contacts: Contact defaults with a default label style of Contemporary, a connector of ampersand, a default salutation style of Formal with the connector and, and a live preview showing the label Mr. David and Mrs. Sarah Cohen and the salutation Dear Mr. and Mrs. Cohen.
The preview updates as you choose, using a sample couple, so you can see the wording before saving it.

How Families Are Addressed

Two separate things, each with its own style and connector word:

LabelSalutation
What prints on an envelope or label.How the letter opens.
Traditional: Mr. and Mrs. David Cohen
Contemporary: Mr. David and Mrs. Sarah Cohen
Personal: Dear David and Sarah,
Formal: Dear Mr. and Mrs. Cohen,

The connector is the word joining the two names. Pick and or & from the caret, or type any word you prefer.

These are the defaults for new families. Any individual family can still be addressed differently — the label and salutation settings on its address win.

Changes here wait for the Save changes bar at the bottom. Leaving with unsaved changes asks whether to stay, discard or save first.

Titles

Two lists — men's and women's — of the honorifics offered when you enter a member. Add, rename and remove work immediately, with no save bar and no confirmation on remove.

Renaming or removing a title only changes what is offered from now on. People already saved keep the title they have.

Relationship Types

The relations you can choose for a member within a family, between two members, and on a yahrtzeit — son, daughter, grandmother, brother-in-law.

Each type carries its counterpart, so recording that one person is someone's son records the other direction at the same time, and you don't have to enter the relationship twice.

"Finish setting up contacts"

A banner at the top of the page lists anything still missing — men's titles, women's titles, relationship types, or either connector. It reads from what is saved, so a connector you typed but haven't saved still counts as missing until you click Save changes.
