# Anti-spam requirements and deliverability considerations

rasa.io takes anti-spam compliance seriously. Failing to comply with anti-spam requirements can damage your sender reputation and affect deliverability for your entire subscriber base. This article covers what you need to know.

### CAN-SPAM Act requirements

The CAN-SPAM Act sets the rules for commercial email in the United States. To comply, every commercial email you send must:

1. Use accurate, non-misleading header information (From name and email)
2. Use honest, non-deceptive subject lines
3. Identify the message as an advertisement where applicable
4. Include your physical mailing address (rasa.io includes this in every newsletter footer — set it in **Settings → Name & Company**)
5. Tell recipients how to opt out of future emails
6. Honor opt-out requests promptly (within 10 business days)
7. Monitor anyone sending email on your behalf

### rasa.io handles several of these automatically

- **Unsubscribe link** — included in every newsletter footer automatically
- **Physical address** — pulled from **Settings → Name & Company** and included in the footer
- **One-click unsubscribe** — supported for Gmail and other clients that require it

### Deliverability best practices

- **Only email people who opted in** — sending to purchased lists or contacts who didn't subscribe is a fast way to damage your reputation
- **Keep your list clean** — regularly remove hard bounces and long-term inactive contacts
- **Authenticate your domain** — SPF, DKIM, and DMARC all help email providers trust your messages. See **How to authenticate your domain**
- **Monitor spam rates** — use Google Postmaster to track spam complaints. Keep rates below 0.1%
- **Avoid spam trigger words** — subject lines with "FREE," excessive punctuation, or all caps can trigger spam filters
