Dear Aspirant,

If you have asked to correct some details in your form by the gate authorities and you have corrected your details in the form then you don't need to email the same to the authorities.

However, if you have asked the authorities for some correction and then they have asked you for the documents, then you might have to send them the documents. In a normal case, it is not required to send any documents by the mail.

Hope this helps, Thank you.

No. It's not required. Once you make the necessary corrections to your application and submit it, the servers will capture the same. You needn't email any documents or proof of correction. You need to keep the proof for your future reference, lest any discrepancy occurs in the near future. Take a print out of the confirmation of the changes made to your application form as requested.
