# Multiple Email Addresses vs Domains ### Email Limitations Popular services like Gmail and Outlook recently made [changes](https://blog.google/products/gmail/gmail-security-authentication-spam-protection/) to curtail the amount of spam that gets sent. As a result, you should send **no more than 100 emails per day** to reduce likelihood of always ending up in the spam folder or getting blocked completely. The exception is if you have a long history of being a reputable brand (think at least a small-cap company that has been sending emails for years). ### Workarounds There is an ongoing debate in the community about whether or not this applies per email address (e.g. ), per email domain (e.g. @gethyperscale.com), or per email subdomain (e.g. @mail.gethyperscale.com) #### High-risk solution Create multiple emails (e.g. and ) for the same domain and send 20-100 per day from each email address. This can get your entire domain flagged. This means buying 1 domain and creating multiple email addresses. #### Medium-risk solution (most common practice) Create multiple subdomains (e.g. and ) for the same parent domain and send 20-100 per day from each email subdomain. This means buying 1 domain, and then creating multiple subdomains with individually [verified records](/email-best-practices/how-to-authenticate-email-dkim-dmarc-spf.md). #### Low-risk solution Use multiple domains and send from 1 email address per domain (e.g. and ) send 20-100 per day from each domain. This means buying multiple domains with individually [verified records](/email-best-practices/how-to-authenticate-email-dkim-dmarc-spf.md). ### **Absolute limits** Even if you create subdomains, there are still absolute limits to be aware of at the overall domain level. You may only send up to 5,000 emails to personal Gmail accounts within a 24-hour period. This is the total of your domain AND subdomains (e.g. mail.domain.com and domain.com). Note: On Hyperscale, you generally won't run into this limit issue since we focus on B2B emails (e.g. ) rather than personal @gmail.com emails.
