# EMAIL BEST PRACTICES

- [How to authenticate email (DKIM, DMARC, SPF)](https://docs.gethyperscale.com/email-best-practices/how-to-authenticate-email-dkim-dmarc-spf.md): The following requires someone with admin access to your domain to complete. It is highly recommended you do this to reduce likelihood of ending up in the spam folder.
- [Multiple Email Addresses vs Domains](https://docs.gethyperscale.com/email-best-practices/multiple-email-addresses-vs-domains.md): We recommend sending 20 per day for new email accounts and no more than 100/day to keep your inbox from being flagged as spam by Gmail.
- [Warming Up New Email Addresses](https://docs.gethyperscale.com/email-best-practices/warming-up-new-email-addresses.md): Note: there is an ongoing debate within the community about whether or not Gmail and Outlook have gotten smarter about detecting warm-ups. So proceed with caution.
