Support for Multilingual Plugins

MailPoet does not directly support qTranslate, WPML, or Polylang.

This said you can still use MailPoet with these plugins to send standard newsletters. Simply ensure:

to have forms for each language;
translate the signup confirmation email in all languages since there's only 1 confirmation email;
translate the Unsubscribe page and the Manage Your Subscription page.

MailPoet works pretty well with MultilingualPress or WeGlot otherwise.

1. Create a list for each of your languages;

2. Create a form for each of your languages. Each form should be tied to its respective language;

3. Add each form to your websites, so they show in their respective language;

4. In your site's In MailPoet's Settings > Sign-up Confirmation, update the content of the email to be in all languages;

5. Send newsletters or emails in a language to the corresponding list.

This is a list of currently known WPML issues, but as MailPoet does not officially support WPML, this is likely not a complete list.

Abandoned Cart automation only works for the main language, not alternate languages
Post Notifications that filter based on language, or based on language-specific categories, do not pull out any posts other than for the default language
back end text uses WPML’s translations rather than MailPoet translations, which is sometimes incorrect or comes into conflict
list management, such as sign up forms or the Manage Subscriptions page, is not language-specific so all customers see all options
