Ecommerce sites without autoresponders are doomed!

So many small businesses need help with this online stuff, they really do.
I placed an order for a present for someone and paid by Paypal. I checked my email but had received nothing other than the Paypal receipt. Where’s the order confirmation from the site I ordered from? I thought.
A couple of days later I cracked them an email to chase and they replied cheerily: “Oh you should have received an email confirmation from Paypal! Your order has been despatched…”
Hmm, what they didn’t even register was that I should also have received an email from their site when I placed the order and another when the order was sent – instead I was left wondering if the order had been received and processed by the shop itself.
The businesses that will survive are the ones who keep up with customer expectations. This is 2019 and that simply isn’t good enough.
