Email Marketing

Email marketing is the highest-ROI digital channel because you own the distribution. Unlike social media algorithms that can throttle your reach overnight, your email list is a direct, algorithmic-free line to your audience. It encompasses newsletters (broadcasting), automated sequences (drip campaigns), and lifecycle triggers (abandoned cart, re-engagement).

The Trap

The most expensive mistake is building a massive list through a cheap giveaway (e.g., 'Win an iPad!') and then blasting them with irrelevant promotions. These subscribers will never buy, but they will mark your emails as spam, destroying your domain reputation and ensuring your emails to actual paying customers end up in the junk folder.

What to Do

Segment your list based on behavior, not just demographics. If a user clicks a link about 'SEO Services' in your newsletter, automatically tag them and trigger a 3-part educational sequence specifically about SEO, culminating in a targeted pitch. Relevancy drives revenue.

In Practice

Morning Brew grew to 3 million subscribers and a $75M valuation entirely through their daily email newsletter. By ruthlessly focusing on engaging, conversational copy (avoiding dry corporate speak) and a brilliant referral program built right into the email, they achieved open rates double the industry average.

Pro Tips

01
Clean your list aggressively. If someone hasn't opened an email in 6 months, send one final 'Do you still want to hear from us?' email. If they don't click, delete them. A smaller, highly engaged list is far more profitable than a massive, dead list.
02
Your subject line has one job: get the email opened. Your first sentence has one job: get the second sentence read.
03
Plain text emails (or emails that look plain text) often outperform heavily designed HTML templates because they feel like a personal note from a friend rather than a corporate flyer.

Myth vs Reality

Myth

“Email marketing is dead because of Slack, social media, and SMS.”

Reality

Email consistently generates $36-$40 for every $1 spent, outperforming every other marketing channel. People buy through email.

Myth

“You should email less frequently to avoid annoying people.”

Reality

If your content is genuinely valuable, people want it frequently. If you only email when you want money, even once a month is too annoying.

Morning Brew

2015-2020

success

Morning Brew turned a dry, boring topic (business news) into a highly engaging, conversational daily newsletter. They didn't rely on SEO or paid ads to get their first million subscribers; they built a frictionless milestone-based referral program directly inside the email. A reader could get premium swag (stickers, mugs, sweatshirts) just by sharing their unique link. Because the content was incredibly readable, the referral engine went viral.

Decision scenario

The List Cleansing Decision

You manage email for an e-commerce brand. You have a list of 250,000 subscribers, but your open rate has steadily dropped from 22% to 11% over the past year. Deliverability issues are starting; Gmail often routes your emails to the Promotions or Spam folders.

Declining

Decision 1

You run an analysis and find that 100,000 of your subscribers haven't opened a single email in the last 12 months. What is your strategy for the next campaign?

Continue sending to all 250,000 people. It costs almost nothing to send those extra 100,000 emails, and even if only 0.1% of them buy randomly, it's free money.Reveal

Your emails start going directly to Spam for everyone. ISPs (like Gmail) look at engagement rates (opens/clicks) to determine if you are a spammer. Because 40% of your list ignores you completely, Gmail assumes your content is trash. Your open rate plummets to 4%, and your revenue drops by 60%.

Open Rate: 11% → 4%Revenue: Massive Drop

Segment the 100,000 inactive users. Send them one final 'Do you still want these?' re-engagement email. If they don't click, permanently delete them. Send regular campaigns only to the 150,000 active users.Reveal

Correct. You delete 98,000 dead emails. Your list size shrinks to 152,000, which terrifies your boss. But your open rate immediately jumps to 28% because ISPs recognize your high engagement and put you back in the highly coveted Primary inbox. Your total revenue actually increases because your emails are being seen by the people who want them.
