I am writing an email that has not to be formal. I am trying to translate a phrase from Spanish that goes: 'Nos comunicamos hace unas semanas.' The literal translation would be 'We communicated a few weeks ago' and I am trying to use that phrase to let the receiver know that we were in touch before, and I am re-approaching her to solve something.
I wanted to know if that sounds right and natural or is there another common way to let the other person know that we were in touch before, and use that as an introductory phrase.
