🚨 Big update from Postcards: our email builder just got smarter and faster.
Here’s what’s new 🧵
- Brand-new image gallery = cleaner + faster
- Edit images right in the builder
- Organize with folders (finally!)
- Bulk actions for uploads, renames & more
- Get deliverability warnings before sending
- Fixed bugs: Outlook cuts, mobile spacing, font issues & more
The pre-send check, nine lines:
- width 600–800px
- nested tables + inline CSS
- alt text on every image
- one column below 600px
- dark mode tested, not assumed
- custom preheader, 90 characters
- one CTA per content block
- file size optimised for mobile
Most AI emails come out generic for one reason: the prompt was lazy.
"Write a sales email for my company" gives the AI nothing. So it guesses, and you get junk.
Here's the 6-part fix, plus 30+ ready prompts 🧵
The tip nobody uses: tell the AI what to AVOID.
"No exclamation marks. No spam trigger words. No clickbait."
Boundaries shape output as much as instructions do.
No more "not THAT button, the other one."
