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
