#23 - How We Do Quality Control (2)
Been down a deep rabbit hole recently w/ DPR Live, a South Korean rapper and hip-hop artist.
His signature sound? Starting songs w/ ‘coming to you live’.
I blame his songs for being earworms, but this is Jfoo ‘coming to you live’ with part 2 of quality control for emails.
If you haven’t checked out part 1, you can do so here.
Let’s get rollin’
5) Mobile Optimization
Mobile is king, and will remain king for many years to come (take a look at semrush’s graph below).

Not optimizing for mobile is like lighting money on fire, and then flushing it down the toilet for good measure.
What the team first does is to send themselves a preview to view on their mobile.
We check to see if there are duplicate blocks (or blocks not supposed to be showing on mobile view).
Ease of navigation is up next - are links clickable with no problem?
Finally, aesthetics - how do the image/text blocks look? Are they too big/small? (typically, we do 16px for the body, and 22px for the headlines)
Example of how our email looks like on mobile below.

6) Grammer, spelling, extra spaces, punctuation errors
Noticed how I misspelled ‘grammer’ above?
We’re all human, it happens.
But the moment your customer notices, they stop to think.
We never want our customers to think.
There’s system 1, and system 2 thinking.
System 1 is an intuitive automatic process - xyz’s gonna make me look good so I buy xyz
System 2 is more methodical, slow - okay so for $34.99 I get xyz and xyz take 3 months to make me look good.

Try not to let them get to system 2.
7) Discount codes are active
When you run email at our scale, I can almost guarantee you this is going to rear its head at least a couple of times.
Again, a human error, but one that’s going to lead to loads of unhappy customers, and time spent on customer support.
8) Images are of good quality/not blurry
Not sure if this shows up well, but the below image is blurry.
Again, not the best experience for your customers.

9) Images are linked/go to relevant pages
Your customers are going to click on your images.
Make sure they’re linked in both desktop and mobile previews, or you’re gonna lose out on precious conversions.
Also, if your image is a model wearing a top, make sure it goes to a ‘tops’ collection, vs the store home page.
And that’s a wrap!
Quality control is not sexy.
But you’d be surprised. Optimizing the little things leads to MoM incremental growth.
Hopefully these past two weeks has given you a solid frame of reference, and feel free to reach out if you have any questions!
Have a great weekend.
