One thing that I don't see enough in the ecom space is follow-up emails after the sale.
It's a simple automation to set up, and your customers will appreciate getting these emails.
Think of it this way, when you sit down at a restaurant and order your food, the waiter doesn't drop your food off and ignore you the rest of the night, right?
(Well, a shitty waiter might)
A good waiter will follow up with you, ask how your food is, and if you need anything else.
And when you finish your meal, they'll typically ask if you want to purchase a dessert.
You need to do the same thing with your customers.
Whenever they make a purchase, send them an email and get them excited about the product.
Then a few days later, once they've had time to use the product, follow up with them!
Ask them how they like the product.
Give them some tips/guidance with their product.
And towards the end of these emails, don't be afraid to pitch an item that will compliment their purchase.
If you sell a consumable, send them an email whenever they should be low on their supply.
Also, you don’t have to make these emails fancy.
Make them human—plain text emails.
For starters, I'd suggest 3 emails for your "follow-up sequence," but feel free to add more.
Hope this was helpful.
