Salesforce Marketing Cloud
1. Scenario Question ✅
Your marketing team wants to re-engage customers who have not made any purchase in the last 6 months.
Customer details are stored in a Customers Data Extension, and purchase information is stored in an Orders Data Extension.
You need to identify:
Customers whose last purchase was more than 6 months ago
Customers who have never made a purchase
How would you write an SQL query in Salesforce Marketing Cloud to create this audience?
My Answer
SELECT
c.CustomerID,
c.Email,
MAX(o.OrderDate) AS LastPurchaseDate
FROM Customers c
LEFT JOIN Orders o
ON c.CustomerID = o.CustomerID
GROUP BY c.CustomerID, c.Email
HAVING
MAX(o.OrderDate) <= DATEADD(MONTH, -6, GETDATE())
OR MAX(o.OrderDate) IS NULL
Explanation:
LEFT JOINensures that customers who never placed an order are also included.MAX(o.OrderDate)returns the most recent purchase date for each customer.GROUP BYis used to aggregate data at the customer level.HAVINGfilters customers who:Purchased more than 6 months ago, or
Have no purchase history (NULL order date).
This query helps create a re-engagement audience that can be used in Journey Builder or Email Studio.
2. Scenario Question ✅
You are building a Journey where users should exit automatically if they have not opened any email in the last 60 days.
How would you create the audience for this requirement using SQL?
My Answer
SELECT
s.SubscriberKey,
s.EmailAddress
FROM _Subscribers s
LEFT JOIN _Open o
ON s.SubscriberKey = o.SubscriberKey
GROUP BY s.SubscriberKey, s.EmailAddress
HAVING
MAX(o.EventDate) <= DATEADD(DAY, -60, GETDATE())
OR MAX(o.EventDate) IS NULL
Explanation:
This query identifies subscribers who are inactive or never opened emails, allowing them to be excluded or exited from Journeys.
3. Scenario Question ✅
How can you join two Data Extensions in Salesforce Marketing Cloud using SQL? Explain with a live example.
Live Example Answer
Assume we have two Data Extensions:
1️⃣ Customer_Profile
SubscriberKey | EmailAddress | Country |
|---|---|---|
SK001 | India | |
SK002 | USA |
2️⃣ Purchase_History
SubscriberKey | OrderID | OrderAmount |
|---|---|---|
SK001 | O1001 | 2500 |
SK001 | O1002 | 1800 |
SQL Query
SELECT
p.SubscriberKey,
p.EmailAddress,
p.Country,
o.OrderID,
o.OrderAmount
FROM [Customer_Profile] p
INNER JOIN [Purchase_History] o
ON p.SubscriberKey = o.SubscriberKey
Result Output
SubscriberKey | EmailAddress | Country | OrderID | OrderAmount |
|---|---|---|---|---|
SK001 | India | O1001 | 2500 | |
SK001 | India | O1002 | 1800 |
Interview Insight
INNER JOINreturns only matching recordsSubscribers without purchases (like
SK002) are excludedUsed commonly to create targeted audiences based on behavior
My Strong Interview Line
“I use INNER JOIN when I want only matching records and LEFT JOIN when I want all subscribers, even if related data is missing.”
