Hi Anchal,

Usually this is due to how DMARC is set up for amazon.com. When mail
lists relay your messages without taking ownership of the envelope, it
invalidates the DKIM signatures and the DMARC policy can cause email
to be flagged as forged / spam.

If you configure your mailer and git to use amzn.com instead of
amazon.com it may help, as the DMARC policy for amzn.com is "none"
[1] rather than "quarantine" for amazon.com [2].
