If I were building an email architecture plan from scratch for a company today, here's exactly how I'd set it up to get more emails delivered, stay compliant, and make more money.

1. Isolate your email channels completely

• Separate transactional emails from marketing campaigns.

• Create different sending subdomains (or domains) for different email types (marketing, transactional, sales, etc.).

• Keep risk profiles separate. Don't let one bad email batch destroy your entire brand.

• Use different IPs for high-volume vs. high-value communication.

2. Build your technical foundation properly

• Set up SPF, DKIM, and DMARC authentication protocols on EasyDMARC.

• Use BIMI so your brand logo shows up in inboxes.

• Create a proper DNS setup with clear sender policies.

• Set up branded links, SSL for tracking domains, reverse DNS, and feedback loops.

3. Get compliant before sending a single email

• Document how you collect data and build your lists.

• Build preference centers where people can choose what they receive.

• Create clear unsubscribe processes that actually work.

• Plan when to keep data and when to delete it.

4. Warm up systematically

• Start small (only with your most engaged subscribers).

• Slowly increase volume (5%, 10%, 25%, 50%, 100%).

• Watch where your emails land in the first 30 days.

• Focus on building a good sending reputation before scaling up.

5. Measure what matters

• Look beyond open rates. Focus on real engagement.

• Track how many emails actually reach the inbox.

• Monitor spam complaints (keep under 0.3%).

• Don't chase vanity metrics — track health metrics.

• Check your domain and IP reputation (Google Postmaster, Microsoft SNDS).

6. Actively manage your sending reputation

• Fix engagement drops before they hurt your reputation.

• Group subscribers: engaged vs inactive, recent vs cold.

• Regularly clean your list (re-engage or remove inactive subscribers).

• Check blacklists daily.

• Use engagement-based grouping.

Building a high-performing email operation isn't luck.

It's strategic planning, technical know-how, and constant improvement.

The difference between average and exceptional email performance is the foundation you build.

Ignore it and you'll pay the price later.

Master it and you'll have an email growth engine that compounds for years.

Best,
Alec
