Email Spam Guidelines
Email campaigns are only successful if your recipients receive the email message. There are several best practices to help make sure your email doesn't get marked as spam. For more information, see the following:
You can also improve your domain's reputation as a non-spammer by preventing spam on both incoming and outgoing mail. Sometimes, outgoing spam happens because spam messages came in first. Therefore, preventing bad email from coming in helps keep you from sending out spam.
Consider the case capture address you've set up. If you use a dedicated custom case capture address, you can filter spam with an external spam filter service. Bots can find these email addresses and send spam messages to them.
These spam messages can get your domain added to a blocklist by major mail providers because of the volume of sent email. For more information about case capture email addresses, see Using Email Case Capture.
For example, set up a branded case capture address such as support@cases.example.com. Change your MX DNS record for cases.example.com to send all email traffic for this domain to your spam filter service provider. After filtering, clean traffic goes to your SMTP server as configured on the spam filter side. Your server then redirects the branded capture case email address to the NetSuite case capture address.
Another best practice to prevent receiving spam is to keep your group email addresses private as much as possible (for example, the email addresses for email case capture and case profiles). Minimize the number of users, and include only those who should be involved in the communication. If a spammer gets group email addresses, it can open a spam distribution channel.
For spam distribution channel attacks, NetSuite protects the reply-to-case scenario only. For more information, see Customer Responses to Cases. Other communications (transactions and messages) can't be protected the same way, so it's essential to keep email addresses private.
Email Sent from NetSuite
Email messages sent from NetSuite are different, depending on where they're sent from, because of the templates and how they're sent. For example, campaign emails and a saved search email alerts use different footers and the sending domains, so they might behave differently with spam filters.
To help your emails get delivered, ensure DMARC compliance by using DKIM keys for every email domain your organization uses.
