There are so many languages in the world it is practically impossible for a company to support all of them without a little help. Luckily, there are many options when it comes to supporting people in different languages, and none of them require you to hire any additional people or have a huge, remote global staff.
If you have a customer that emails in in a language that no one on your team speaks, but you still would like to support there are a few steps:
The most important point is that you let your customer know that you are using a translation service and that it’s because you don’t have any native speakers of their language on your team. This will make them much more understanding of any potential errors that Google Translate might make, and also may encourage them to speak in English instead. Many customers, especially if your product has excellent localization, won’t even think twice about writing in their native language.
That being said, they may still speak English, and be willing to do so if that is their main way of getting support.
