Introduction:

As a product manager in MarTech for the past 10 years, I've developed an unusual habit: I regularly check my Gmail spam folder. While this might sound odd & tedious, it's given me unique insights into the evolving battle between email marketers and spam filters. Here's what I've learned about making email marketing work in today's landscape.

The Enduring Power of Email:

Email is one of the most important inventions of the 20th century, next to the Internet. Think about how your life and work are intertwined with it. The whims and fancies of a big corporation do not own it. It cannot be that easily blocked by a corporation or government. It is a democratic tool available to everyone. Email remains one of the most powerful tools in digital communication. Consider these facts:

• Email marketing generates $36 for every $1 spent (DMA, 2023) (link)
• 4 billion people use email daily (link)
• Unlike social media platforms, email gives you direct ownership of your audience relationships.
• It's platform-independent and globally accessible.

These numbers demonstrate why effective email marketing remains a cornerstone of digital communication strategies. With recent changes from major email providers like Google and Yahoo, understanding what makes email marketing effective has become more critical than ever. Let's dive into what makes emails reach their intended destination.

The Evolution of Email Marketing:

I have seen marketers come full circle when it comes to email.  I've watched marketing trends come and go:

• 2016: Snapchat was supposed to kill email
• 2019: Slack and team messaging tools were the 'email killers'
• 2022: TikTok was predicted to replace traditional marketing channels
• 2024: Email continues to thrive, with newsletter platforms like Substack growing exponentially

The reason? Email combines unmatched ROI with remarkable openness and flexibility. While some companies chase trendy platforms, others, like Warby Parker (link), have built billion-dollar businesses on the backbone of effective email marketing (along with other channels too).

Open to all, delivered to a few—Email’s core challenge:

Openness, flexibility, and affordability are the key characteristics of email as a channel. But that is a double-edged sword. Genuine people who want to connect with their audience rely on it, while spammy marketers or scammy salespeople also depend on it. Today's email scams have evolved far beyond our comprehension. Modern threats include:

• Sophisticated phishing attempts mimicking major brands
• AI-generated personalized scam emails
• Business Email Compromise (BEC) attacks
• Cryptocurrency investment scams

This environment makes it crucial for legitimate marketers to stand out.

Key Principles for Effective Email Marketing:

The key challenge as an email marketer is to wade through these complexities to acquire customers and engage with them. Here are a few key things that I have learned to make email an effective channel:

1. Respect the inbox - Think of email like the living room of your subscriber's digital home:some text
   • Segment your emails by purpose (promotional, transactional, newsletters)
   • Use preview text effectively to set expectations
   • Maintain consistent sending schedules
   • Make it easy for your subscribers to opt out or unsubscribe
2. Email deliverability hygiene checklist - Technical foundation matters more than clever subject lines::
   • SPF (Sender Policy Framework): Authenticates your sending domain
   • DKIM (DomainKeys Identified Mail): Ensures email hasn't been tampered with
   • DMARC (Domain-based Message Authentication): Protects against spoofing
   • Regular list cleaning: Remove hard bounces and inactive subscribers
   • Maintain a suppression list for unsubscribes‍
3. ‍Avoid Spam Triggers - Modern spam filters are sophisticated but still watch for:
   • Excessive punctuation (!!!) or ALL CAPS
   • Trigger words like 'free,' 'guarantee,' 'no risk'
   • Large attachments in marketing emails
   • Image-only emails without text
   • Mismatched sender domains

4. Keep the main thing, the main thing - For effective email marketing, focus on metrics that truly matter instead of obsessing over vanity metrics:
   • Track revenue per email
   • Measure customer lifetime value by email engagement
   • Monitor unsubscribe reasons
   • Test different conversion goals (downloads, purchases, registrations)
   • Use attribution modelling to understand email's role in the customer journey 

Conclusion: 

‍Email marketing succeeds when you combine technical excellence with genuine value for your subscribers. Focus on building trust, maintaining a clean sending reputation, and delivering relevant content. The tools and tactics may evolve, but these principles remain constant.
