> **Quick answer —** Localize the onboarding sequence before the interface. It reaches every new user, drives activation, and needs no engineering work — but send times, examples and calls to action all have to change with the language.[Vitra.ai Universe](https://www.vitra.ai/platform) ships product and customer content in every language.

## The sequence reaches everyone

Every signup gets the onboarding emails. Not every signup opens the help centre or reads the marketing site again.

That makes it the content with the widest reach per word a SaaS company owns, and it sits in an email tool that marketing already controls, which means no ticket and no release.

## Translate, then rewrite three things

Element

Handling

Body copy

Translate

Subject line

Rewrite locally, never translate

Examples and sample data

Replace with local ones

Call to action

Translate, then check it fits the button

Send time

Per market, not global

Sender name and reply-to

Local where you have local support

Subject lines decide open rate and truncate at different points per client and language, so front-load the meaning rather than following the source word order.

Sample data is the giveaway. An onboarding email walking a German user through setting up "Acme Corp, 123 Main Street" reads as a translation of somebody else's product.

## Send times are per market

A sequence timed to fire three hours after signup is fine. A weekly nudge that goes out at 9am Pacific arrives in the middle of the night across Europe and Asia.

Splitting the send by market is a small operational change with a measurable effect on opens, and it also lets a correction go to one language without disturbing the others.

## Activation is the number, not opens

Opens tell you the subject line worked. Activation tells you the sequence did. Compare activation rate for the localized cohort against the English cohort in the same market before the change. If it does not move, the emails were translated but the product they lead into was not — which usually means the [interface and help centre](https://www.vitra.ai/saas/saas-localization) are still English at the moment the user arrives.

## Keep it consistent with the product

Feature names come from the same [memory](https://www.vitra.ai/features/translation-memory) as the interface, or the email teaches a name the product does not use.

Run [quality control](https://www.vitra.ai/features/quality-control) before send. Email cannot be recalled, which makes it the one channel where the check has to be upstream of publication rather than a correction afterwards.

## FAQ

**Why localize onboarding email before the interface?** Because it reaches every new signup, drives activation, and lives in a tool marketing already controls. It ships without engineering time while interface work is still being scheduled.

**Should email subject lines be translated?** No, rewritten locally. They decide open rate and truncate at different points per client and language, so the meaning has to be front-loaded rather than following the source word order.

**Do send times need to change per market?** Yes. A sequence timed globally arrives in the middle of the night somewhere, and splitting the send by market also lets a correction reach one language without disturbing the others.

**What measures whether localized onboarding worked?** Activation rate for that market, not opens. If activation does not move, the emails were localized but the product they lead into probably was not.
