First, great question to launch excellent insights, Steve DiGioia.

For us, we find a few things we do make the greatest impact (that's important. It's easy to spin your wheels on things that don't make an impact. It's also important to do things that resonate with you and your team, so they are done authentically and from the heart.Find that balance, and everything becomes fun, fulfilling and effortless.)

1) Every product we make comes with a postcard.
On one side are the product instructions. And a link to more details.

On the opposite side is one of 870 quotes we've either created from internal dialogue. Or that we've culled from our friends on Facebook, Twitter and in text dialogue with customers and friends.

And I'm not talking the classic Oprah, Bruce Lee, Dale Carnegie quotes. 
These are usually found deep within some thread. Some missed gem that, when graphically enhanced and exposed to the larger audience, become deeply meaningful ideas, thoughts and admonitions. 

2) Samples.
In our business (custom, personalized supplements), it's important that we read between the lines of what our customers order, and find ways to add value to their desired outcome.

So providing samples of products that might be very helpful to their goals is key.
(One of my lead employees really hates that we give so much product away like this. But I have to share that the alternative is more traditional advertising and marketing, which are great. But lack the actual experience and engagement of the product.)

3) Texting Support
We keep a refreshed, rotating group of our newest 200 clients in Textra (a cross-platform texting app that supports images and audio). As our clients engage with their custom supplements, we help them navigate their progress from Sick to Superhuman (our definition of the path we all take as we address a physiological issue or limitation, and, hopefully, kick it's butt).

This very tight feedback loop allows us to better understand our client's needs.
Build better solutions.
And, by adding voice and images, we show them we truly care about their short and long term health and quality of life goals.

These three are the legs of our Customer Delight process.
If we do them well, we find our customers become co-evangelists for us.
And those texts? Yeah, they are filled with incredible testimonies and encouragements from those folks who get our mission. And experience results.

Here's to your own awesome customer delight stories (looks like you've got quite a few for me to dig into here!).

Thanks again, Steve!
