[Grammar] Hear or Heard

[Nerul]

Hi, first time on this forum and I'm not a native English speaker and have a simple question. Which one is grammatically correct: I will let you know when I hear from them or I will let you know when I heard back from them. Many thanks.

Welcome to the forum, Nerul. :hi:

You need 'hear (back)' or 'have heard (back)'.

thank you.... that makes sense. Thanks again. I will never have that doubt now.:-D
