email_set_default_locale
Set the project's default locale — the fallback used to pick a template translation when neither the send call nor the contact's `locale` attribute carries one.
write email_set_default_locale
Set the project's default locale — the fallback used to pick a template translation when neither the send call nor the contact's locale attribute carries one. Tag like 'fr' or 'pt-BR'; pass null to clear (sends fall back to the base template language). A missing translation never blocks a send — it falls back to the base version.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
locale | string | null | Yes | Locale tag like 'fr' or 'pt-BR'. null clears the default. |
projectId | string | No | Target company (project id) — required on project-scoped tools. Call email_list_projects to enumerate companies. |
set_daily_send_capwrite
Set an OPTIONAL daily send cap that tightens below the provider plan's own daily limit (emails/day across ALL sources — API, automations, copilot).
set_utm_taggingwrite
Configure auto UTM tagging: params appended to every external link in outgoing emails (Google Ads-style, set once and forget).
