A good upsell helps the customer get more from what they already bought. A bad one just asks for more money. The difference is relevance and timing.
Upsell or cross-sell?
- Upsell: a better or bigger version. A larger plan, a premium edition, a longer service.
- Cross-sell: something that goes with it. Care products, a matching item, a related service.
Both work the same way: offer what genuinely fits, at the moment it makes sense.
The rules
- Only offer what makes the first purchase better.
- Say why it fits this customer.
- Time it to a real moment, not just 'after purchase'.
- Make it easy to ignore. One offer, no pressure.
Example: after they have used it
Subject: You are using the starter plan a lot
Hi Daniel,
You have taken 85 bookings through the starter plan this month, close to its limit of 100.
If you expect more, the standard plan has no booking limit and adds text reminders, which usually cut no-shows. It is 20 dollars more a month.
Happy to switch you over, or to leave things as they are. Just reply.
Example: a natural add-on
Subject: Keeping your new table looking new
Hi Amira,
Your oak table arrives on Thursday. Oak lasts for decades with a little care, and the first year matters most.
Our oil and cloth set keeps the surface protected from water marks. It is 25 dollars, and we can add it to the same delivery if you order by Wednesday.
Example: when they are running out
Subject: Time for more coffee?
Hi Sam,
It has been about four weeks since your last bag, so you might be running low.
You can reorder the same 250 g bag in one click, or switch to the 1 kg bag, which works out 20 percent cheaper per cup.
Example: a service client
Subject: An idea for next quarter
Hi Lea,
Your monthly bookkeeping is running smoothly. You mentioned you spend a day at the end of each quarter on tax prep.
We can take that on too, as part of a quarterly package. It is 150 dollars a quarter, and you would get that day back.
What to avoid
- Customers also bought
- Upgrade now before it's too late
- You won't believe this deal
- Don't miss out
- Irrelevant offers. A random product feels like spam.
- Too soon. Offering an upgrade before they have used the first thing.
- Too often. The same offer every week teaches customers to ignore you.
Remember what they bought
The best upsells depend on knowing each customer: what they bought, how they use it, what they told you. That is the same knowledge that helps you keep customers coming back. For one-off buyers who left before paying, see abandoned cart emails.
