Best practice includes the use of industry-standard email authentication through DomainKeys Identified Mail (DKIM) and campaign email domains. Best practice also includes the careful maintenance of recipients lists who have elected to receive your email messages. Both practices work to increase your deliverability, and reduce the incidence of your email messages being reported as spam.
The following sections show you how to implement email campaigns in NetSuite, and offers tips for optimizing your email campaign delivery.
Five Golden Rules for Outbound Email
| 1. Always send using a FROM domain you control | Do not send email messages on behalf of customers, and never use customer email addresses in the FROM field. Never send from addresses using a DNS record you don’t control. For emailed forms, or email messages related to transactions, ensure that the Return Email Address field on the Company Information page is specifying your domain. (A user with an Administrator role can go to Setup > Company > Setup Tasks > Company Information to view the Return Email Address field). |
| 2. Manage Your Scripts | Regularly check your SuiteScript outbound email scripts. Promptly delete any obsolete scripts or deprecated customizations. |
| 3. Be Compliant | Ensure you have proper DNS records set up for DKIM on the domains you send email from. Consider setting up a DMARC policy record for your company’s entire email infrastructure. For NetSuite purposes, it is not necessary to set up DNS records for SPF on the domains you send email from. However, depending on the needs of your company, it might be necessary to create a DNS record for SPF. |
| 4. Be Aligned | If you have an email relay between NetSuite and your mailbox provider (where the MX points), ensure the MAIL-FROM (ENVELOPE-FROM, RETURN-PATH) passes the SPF check. |
| 5. Be Hygienic | Never send spam or unwanted email. Never send single email more than a single time. Always honor unsubscribe requests. Do not send or forward email with content (especially attachments) that is unknown to you. |
