How do I ensure my newsletter sends with a publishing platform are compliant with email authentication and consent rules?

To stay compliant when sending newsletters through a publishing platform, focus on two areas: email authentication and recipient consent/preferences.

1) Set up proper email authentication

This helps mailbox providers verify that your messages really come from your domain.

• SPF: Authorizes the platform to send email on behalf of your domain.
• DKIM: Adds a cryptographic signature proving the message wasn’t altered and came from an authorized sender.
• DMARC: Tells receiving servers how to handle messages that fail SPF/DKIM and provides reporting.

Best practice

• Use your own sending domain or subdomain, e.g. news.yourdomain.com.
• Make sure the platform gives you the exact DNS records to add.
• Confirm alignment between the “From” domain and the authenticated domain.
• Test before sending to your full list.

Also helpful

• Custom tracking domain for open/click links.
• Branded “From” address and consistent sender identity.
• Dedicated sending domain if the platform allows it.

2) Collect and document consent properly

Consent rules vary by country, but the safest approach is to use clear, explicit permission.

Good consent practices

• Use opt-in sign-up forms that clearly say what subscribers will receive.
• Avoid pre-checked boxes.
• Keep a record of consent:
  • date/time
  • source/form
  • IP address if available
  • consent wording shown
• If you use double opt-in, even better: it provides stronger proof and improves list quality.

If you send to existing contacts

Make sure you have a valid lawful basis to email them, and that your messages match what they agreed to receive.

3) Include required unsubscribe and identity information

Most laws and platform policies expect this.

• A working unsubscribe link in every newsletter.
• Honor opt-out requests promptly.
• Include your physical mailing address or other required sender details.
• Don’t make unsubscribing difficult or require logins.

4) Keep your list clean and permission-based

• Don’t buy or scrape email lists.
• Remove bounced addresses, complainers, and inactive contacts.
• Segment subscribers by consent source if you have multiple sign-up methods.
• Avoid sending to people who haven’t engaged for a long time without re-confirming consent.

5) Follow regional privacy and marketing laws

Depending on where you and your subscribers are located, rules may include:

• CAN-SPAM (U.S.)
• GDPR/ePrivacy (EU/UK)
• CASL (Canada)
• Other local anti-spam and privacy laws

Key differences often involve:

• whether consent must be explicit
• how consent is documented
• what identification/disclosure is required
• whether a lawful basis other than consent is allowed

6) Coordinate with your publishing platform

Check whether the platform:

• supports SPF/DKIM/DMARC setup
• uses shared or dedicated IPs
• allows custom “From” domains
• provides unsubscribe handling
• stores consent logs or integrations
• has compliance settings for your region

7) Operational checklist

Before launching:

• Set SPF, DKIM, DMARC
• Use a branded sending domain
• Add unsubscribe link and sender info
• Confirm consent records are stored
• Verify your signup form wording
• Test deliverability and authentication
• Review privacy policy and terms
• Ensure your platform’s features match legal requirements

If you want, I can also give you a platform-agnostic compliance checklist or a sample newsletter signup form wording that’s safer for GDPR/CAN-SPAM.
