Most people obsess over subject lines.
But here’s the truth…
Your preview text is often doing more damage than your subject line.
Back when I ran MailNinja, I’d spend hours A/B testing headlines…
But totally ignore the preview line.
Until one day I realised:
→ My subject line was 🔥
→ But my preview text said “Can’t see this email? Click here.” 😬
That little line was tanking my open rates.
So I flipped the script.
I started writing preview text first.
And open rates jumped by 10–20% overnight.
Here’s my system 👇
→ Write preview text as a cliffhanger: make people curious
→ Make sure it complements — not repeats — the subject line
→ Check how it looks in Gmail and mobile (preview snippet length matters)
Now I teach this as part of my Email Essentials course inside GrowthKit.
Most founders think subject lines are the secret to high open rates.
Nah.
It’s the subject line + preview text combo that wins the inbox war.
Test it this week and let me know how it goes.
