Student or Learner
Please let me know that below red color sentence is OK? If I use Best Regards do I need further use of Thank you.
I have attached the Tender doc of XYZ.
I agree with D'Arcy (welcome to the forum, D'Arcy).
Additionally, there's no need to capitalise 'regards'.
It's fine for an informal email.
Thanking someone is different from closing with a "regards."
