Email Deliverability 101

Getting into the inbox is step one.
But most founders are too busy writing to worry about where their emails land.

Oops.

Inside GrowthKit, I created Email Deliverability 101 for founders who want emails opened—not ghosted.

It’s simple. Fast. Actionable.

Here’s what you’ll learn:

🔐 → Authenticate your domain
→ Setup SPF, DKIM and DMARC
→ Avoid spam traps
→ Check if you’re blacklisted (most don’t even know)

🧼 → Clean your list regularly
→ Use Clearout with Fluent Forms to validate in realtime
→ Re-validate every 30–90 days with Truelist
→ Kill the duds

📊 → Build your sender rep
→ Use Kit to send consistent campaigns
→ Watch engagement rates
→ Segment & warm up new subs

I’ve seen founders go from 10% open rates to 60%—just by fixing their setup.

Don’t let your emails die in spam.
Deliverability is fixable. And it’s in your control.

Virality is a vanity metric.

Everyone’s chasing virality.

But virality is a vanity metric.

You don’t need a million views.
You need the right 100 people reading your stuff—daily.

Here’s what actually works:

📨 I send a daily email to 7,000+ founders
→ 80% open rate
→ 61% click rate
→ 50+ new subs daily
All built using free lead magnets + daily LinkedIn posts.

🎥 I’ve recorded 250+ Loom videos
Each one becomes:
→ A LinkedIn post
→ A newsletter lesson
→ A short CTA or course clip
→ A prompt inside GrowthKit

🧠 I systemised my content flywheel
→ Capture raw ideas
→ Repurpose via ChatGPT
→ Schedule in Taplio
→ Deliver value, daily

I’m not a creator.
I’m a systems builder.

And this is how I show up every day—without burning out.

Want growth?
Build a system, not a feed.

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.
