Files.com Email Deliverability
Whitelisting Files.com for Deliverability
Application mails from Files.com are SPF, DMARC, and DKIM compliant. If you have email filters in place, you can rely on these technologies. If you need to specifically whitelist Files.com's mail sender IPs (and you are not using Custom SMTP), be aware that Files.com sends mail via Amazon SES, which has a very large IP range, and we don't recommend whitelisting that entire range anywhere. You may be able to use the From or Reply-To address for whitelisting instead.
