Add email domains to organizations in bulk

Jira Service Management sets email domains one organization at a time, ten at most, by hand. With hundreds of organizations, that doesn’t scale.

Atlassian's feature request: JSDCLOUD-14251 — "Add email domains to organizations in bulk / by API" — filed by Atlassian in 2024; admins answered with 5,000+ organizations.

What Jira Service Management gives you

• An email-domain setting on each organization, up to 10 domains, set by hand.
• No API to set it, so no script either.
• It only places new customers. See why existing customers are skipped.

With Customer Roster

1. Make a CSV with two columns, domain,organization — or start from domains-template.csv. One file can change up to 50 organizations; split a longer list into several files.
2. Rules → Domains → Upload domain CSV.
3. Read the dry run: new domains, conflicts (one domain on two organizations), public domains like gmail.com, which are refused unless you turn the check off by typing the domain (see Domains).
4. Confirm. Customers at those domains — existing and new — join their organizations, silently.

No 10-domain limit, subdomains with *.example.com, and conflicts are never guessed. Full guide: Domains.

You can also put domains in an organizations import: a domains column. See Import.
