Summary
Sending bulk emails that resemble Outlook messages while minimizing content compliance reviews requires a multi-faceted approach. Major ESPs facilitate Outlook-like designs, but compliance varies; smaller ESPs offer flexibility, but demand stronger self-management of sender reputation. Deliverability hinges on adherence to legal standards, maintaining list hygiene, proper authentication (SPF, DKIM, DMARC), relevant content, and email testing across clients. High-risk content (e.g., debt collection) requires extra caution. RFC 5322 provides formatting standards, while Microsoft Exchange Online uses mail flow rules. Ultimately, a balance must be struck between achieving the desired aesthetic, respecting deliverability best practices, and mitigating compliance risks.
Key findings
- Design Simplicity: Most major ESPs allow creating emails that look like they were sent directly from Outlook.
- Compliance Variance: ESPs have varying levels of content compliance reviews; some are stricter than others.
- Smaller ESP Tradeoff: Smaller ESPs and self-hosted solutions offer more freedom but require greater responsibility in managing deliverability.
- Content Matters: Content choices, especially high-risk topics, impact deliverability and compliance scrutiny.
- Authentication is Key: Properly configured authentication (SPF, DKIM, DMARC) is vital for avoiding spam filters.
- List Hygiene is Critical: Maintaining a clean and engaged email list improves deliverability and minimizes compliance issues.
Key considerations
- Choose Wisely: Carefully evaluate ESPs based on their compliance policies, features, deliverability, and ease of use.
- Content Strategy: Review content to avoid sensitive topics that may trigger spam filters or compliance reviews.
- Segment and Personalize: Segment your email list and personalize messages for greater relevance and engagement.
- Master Authentication: Configure email authentication protocols (SPF, DKIM, DMARC) to improve deliverability.
- Regularly Clean Lists: Remove unengaged subscribers regularly to maintain a clean and responsive email list.
- Test Email Rendering: Test emails across various email clients, including Outlook, to ensure they render correctly.
- Know the Rules: Adhere to anti-spam laws, data protection regulations, and the acceptable use policies of your chosen ESP.
- Understand Email Types: Distinguish between bulk and transactional emails, and use the appropriate type for the content being sent.
