How would I address someone with the name, Sasha de Lis, in an email?
- Affiliation: We've never met.
- Country: United States
Would I address the email as:
Dear Ms. de Lis?
In general, this is culture dependent. If de Lis is of Dutch origin, then "Ms. de Lis" is correct, although you could even go so far as to maintain the Dutch title which I think is "Mevr." or "Mevrouw".
However... for just about every professional interaction I've ever had, "Dear Sasha" would be absolutely fine.
