Lekalao knows who to write to in which language, and lets you write each e-mail in as many languages as you need. Every language there is is accepted (ISO 639-1 codes), with a region when you need one: fr, en, sw, pt-BR.

​
Each subscriber’s language

A subscriber’s language arrives through:
  • their record, in the interface;
  • the subscription form (the locale field);
  • an import (a langue, language, lang or locale column, as a code or a name: fr, Français, French);
  • the API (locale);
  • their preferences page, where they choose it themselves.
The public pages (confirmation, unsubscribe, preferences) and the system e-mails (confirmation, welcome) appear in that language when the interface knows it, and in the installation’s default language otherwise.

​
Writing a translated version

Above the editor of a campaign, an automation e-mail or a transactional template, the language tabs:
1

The base version

The first tab is the base version, in the list’s language. It is what anyone whose language has no version receives.
2

Add a language

Add a language, type a few letters (“span”, “swah”), choose. A tab appears.
3

Write the translation

In the tab, the subject and the content belong to that language; the preview shows them with the matching lang attribute. The template, the editor and the settings are shared by every version.
4

Save

Save saves every version at once. A version left entirely empty is not kept; the cross on a tab removes the language.

​
Who gets what

For each subscriber, Lekalao takes:
  1. the version of their exact language (pt-BR);
  2. failing that, the version of the language without its region (pt);
  3. failing that, the base version.
A translated subject left empty falls back to the base subject, and translated content left empty falls back to the base content: you may translate the subject alone. The e-mail that goes out carries the language in its <html lang="…"> tag, which helps screen readers and some filters.

​
Sending to one language

To write to one language only, create a segment with Language is…. “Portuguese” takes in pt and pt-BR; “Portuguese (Brazil)” means pt-BR alone.
The versions of an A/B test are not translated: a campaign in an A/B test has no language tabs. To test two subjects in two languages, make two campaigns, each on a language segment.

​
Transactional e-mails

Your application chooses the language on every send, with the locale parameter:
Without locale, the base version goes out. See Transactional e-mails through the API.
