FAQPage Schema
How do I set up SPF, DKIM, and DMARC for email deliverability?

Email deliverability requires configuring SPF, DKIM, and DMARC DNS records to authenticate your sending domain. This Skill provides implementation guidance for setting up these protocols to ensure your marketing and transactional emails reach inboxes compliantly.

What's the best way to implement double opt-in for marketing email compliance?

Double opt-in is the best practice for marketing email compliance, requiring users to confirm their subscription after initial signup. This Skill outlines email capture implementation steps and suppression policies to maintain list hygiene across CAN-SPAM, GDPR, and CASL frameworks.

Do I need to follow CAN-SPAM, GDPR, and CASL regulations for transactional emails?

Transactional emails have different compliance requirements than marketing emails under CAN-SPAM, GDPR, and CASL regulations. This Skill defines the specific implementation requirements and regulatory references needed to distinguish and manage both email types compliantly.

How does email suppression and list hygiene work for opt-out requests?

Email suppression manages opt-out requests by permanently excluding unsubscribed addresses from future sends, while list hygiene removes invalid or inactive contacts. This Skill guides teams through establishing suppression policies and retry logic to maintain deliverability and compliance.

Why are my marketing emails going to spam despite having opt-in subscribers?

Marketing emails go to spam when SPF, DKIM, or DMARC authentication is missing, or when list hygiene and suppression policies are inadequate. This Skill helps diagnose deliverability issues and provides best practices for content, retry patterns, and webhook reliability.

Can I use the same email best practices for both marketing and transactional workflows?

Marketing and transactional emails share deliverability foundations like SPF, DKIM, and DMARC setup but differ in compliance and opt-in requirements. This Skill guides teams to build both email types with appropriate suppression, retry logic, and regulatory adherence across frameworks.
