2X EMAILS

Most people treat email like an afterthought.
But it’s your highest leverage channel.

That’s why I built 2X EMAILS inside GrowthKit.

It’s 86 practical hacks to grow your list, increase opens, and drive clicks—without ads.

Here’s how founders are using it:

📈 → List growth hacks
→ The Subscriber Flow
→ Referral giveaways
→ LinkedIn template + signature CTA
→ Opt-in popups that actually work

⚡ → Open rate boosters
→ The ‘Inbox Zero’ tactic
→ My resubscribe hack
→ Peak send time + subject line stack
→ Segment or die trying

👇 → Click rate tricks
→ Action hooks (clickbait… but clever)
→ The ‘but’ framework
→ Write like a tweet
→ Focus on ONE message
→ Deep linking + templates

Every one of these hacks is something I’ve tested with real campaigns.

If you’ve got an email list and it’s underperforming…
this course is your cheat code.
