I’m officially an email marketing contrarian
My own journey with email over the last 12 years has completely changed how I see things.
Most “best practice” in email is complete rubbish, it's:
Outdated
Unquestioned
Stagnant
The internet is still full of copy-and-paste advice from years ago, no wonder innovation in email (B2B or B2C) is basically non-existent.
3 “best practices” to stop listening to:
“A/B split test your subject lines”
You can’t prove they work; there are too many variables you can’t control (time, impulse, bots, servers, curiosity, human behaviour, inbox clear-outs).
A winning open rate doesn’t mean anything positive on its own - it's a pointless test tbh.
Subject lines should be part of your whole copy strategy, not an isolated stunt you throw away after one send.
2. Double opt-in
In 2025, prevention is everything. If you’re collecting bad data in the first place, that’s the problem to fix, with better list hygiene, form validation, and honeypots, not by asking for permission twice.
Double opt-in just adds friction and wastes one of the most valuable emails you’ll ever send (the welcome email).
3. Engagement & “industry benchmarks”
Google “email engagement” and you’ll find all sorts of rules: “cut everyone who hasn’t opened in 30 days” or “120 days” or whatever the blog says this week.
Then there’s “industry benchmarks”, which are outdated, from a small pot and not relevant - care about what you're doing, not what others are.
The only benchmark that matters is the one you build from your own data.
