Emails from The Gate Index will always have the gateindex.com domain name at the end of them. For example, emails from support@gateindex.com, no-reply@gateindex.com, and any other email from the @gateindex.com domain can be trusted.
We also send emails from The Gate Index sub-domains. For example, a message from contact@updates.gateindex.com are valid. Note that the email address ends in .gateindex.com.
Regardless of sub-domain, we cryptographically sign all of our emails using DKIM and protect our domain against unsigned email with DMARC.
