Email to Hotmail or Gmail goes to Junk / Spam folder
Some possible reasons that cause this issue:
a) IP not set with proper SPF or PTR records.
b) IP is blacklisted and classified as spamming IP.
c) High volume of emails goes to Hotmail /Gmail server from IP or source that Hotmail/Gmail users classify as Junk or Spam mail.
If any of the IPs were earlier blacklisted, it may take some time (estimate about 3-7 days) for Gmail and Hotmail spam filtering system to establish that your email gets valid messages. At the same time, you may request your Gmail/Hotmail user (recipient) to mark your emails as Not Junk or Spam.
