Hey, Grow Newsie reader!
If you're still manually sending welcome emails and forgetting to follow up with subscribers, you're leaving serious growth on the table. The most successful newsletter creators in 2025 aren't working harder—they're automating smarter.
Today, I'm sharing the exact automation tools that helped me (and hundreds of other creators) scale from scattered manual processes to systematic growth machines.

Marketing ideas for marketers who hate boring
The best marketing ideas come from marketers who live it.
That’s what this newsletter delivers.
The Marketing Millennials is a look inside what’s working right now for other marketers. No theory. No fluff. Just real insights and ideas you can actually use—from marketers who’ve been there, done that, and are sharing the playbook.
Every newsletter is written by Daniel Murray, a marketer obsessed with what goes into great marketing. Expect fresh takes, hot topics, and the kind of stuff you’ll want to steal for your next campaign.
Because marketing shouldn’t feel like guesswork. And you shouldn’t have to dig for the good stuff.
Here's the reality: your competitors are already using automation to:
Convert 40% more subscribers with perfect welcome sequences
Re-engage inactive readers automatically
Segment audiences without lifting a finger
Generate revenue while they sleep
Manual newsletter management died in 2023. Automation is how you compete now.

The Biggest Automation Mistakes to Avoid
❌ Over-automating too quickly - Start with email sequences, then expand
❌ Ignoring mobile optimization - 60% of newsletter opens happen on mobile
❌ Set-and-forget mentality - Review and optimize monthly

❌ Not testing - A/B test your automation sequences regularly
What's Working Right Now
AI-powered send time optimization is boosting open rates by 15-25%
Behavioral trigger emails are converting 3x better than time-based sequences
Interactive email elements (polls, quizzes) are increasing engagement by 40%
Cross-platform retargeting between email and social is driving 30% more conversions
Your Next Steps
Pick ONE tool from this list and implement it this week. Don't try to automate everything at once—that's how you overwhelm yourself and quit.
Start with lead capture automation (OptinMonster or Sumo), then add email sequences next month.
The creators winning in 2025 aren't the ones with the most tools—they're the ones who master a few key automations and optimize them ruthlessly.
Keep growing!
With love,
Nikhil
