Customer.io Cross-Sell and Upsell Giveaway
Grow your email list with a Customer.io giveaway template built for newsletter signup, first-party data collection, cross-sell and upsell journeys, and email plus SMS follow-up.
Use this Customer.io giveaway template to grow your mailing list with a campaign built around newsletter signup, first-party data collection, and stronger personalised journeys.
Instead of collecting generic subscribers and sending everyone the same follow-up, this template helps you gather richer customer data before and during the campaign. With the Pre-Entry tab, you can collect profile fields that can be synced into Customer.io, use Phone for SMS-ready workflows, ask an intent-based question to identify what matters most to the customer when buying a gaming PC, and use custom actions to capture wishlist intent and invoice data.
This makes the template ideal for brands that want to use a giveaway not only for email capture, but also for better cross-sell opportunities, stronger upsell messaging, more accurate audience segmentation, and more relevant email and SMS journeys after signup.
Use the Pre-Entry tab, Phone field, motivation-based question, wishlist action, and invoice number custom action together so your giveaway sends richer profiles into Customer.io. This makes it easier to separate existing buyers from new leads, personalise journeys, and build stronger cross-sell or upsell campaigns across email and SMS.
What This Template Does
- Grows your list with a high-value newsletter signup action
- Uses Pre-Entry fields to collect customer data before users unlock the giveaway
- Captures buying motivation with a multiple choice question action that supports better cross-sell and upsell segmentation
- Encourages stronger engagement with page visit actions, a wishlist-building mechanic, and product discovery touchpoints tied to cross-sell and upsell intent
- Uses custom actions to collect wishlist intent and invoice numbers from existing customers
- Adds referral-driven reach through a built-in viral share action
- Uses secret code actions in both email and SMS to encourage post-signup engagement
- Rewards full participation with a bonus action at the end of the action stack
Benefits
-
Attract More Subscribers at the Top of the Funnel: Running a competition with a Customer.io integration gives people a clear reason to subscribe, helping you increase newsletter signup volume faster than a standard form alone while keeping the entry experience engaging and conversion-focused.
-
Collect Better First-Party Data from the Start: Instead of collecting only an email address, you can capture useful customer details through Pre-Entry fields, motivation-based questions, wishlist intent, and invoice verification mechanics. This gives you richer first-party data that helps you understand both current customers and future buyers more clearly.
-
Support Better Cross-Sell and Upsell Journeys: A motivation-based question helps identify whether a subscriber cares more about speed, graphics, aesthetics, streaming, or value. That makes it easier to send more relevant cross-sell and upsell messaging after the giveaway.
-
Capture Stronger Purchase Intent for Cross-Sell and Upsell: A wishlist action gives customers a clearer signal about which products a subscriber wants next. This makes it easier to build more relevant journeys in Customer.io, trigger better recommendations, and follow up with personalised offers based on real product interest rather than guesswork.
-
Use Invoice Data to Personalise Follow-Up: A custom invoice number action gives customers a way to identify what someone has already purchased. That creates stronger opportunities to suppress irrelevant promotions, suggest complementary items, and personalise product recommendations more accurately.
-
Build Data-Driven Segmentation: By mapping competition fields into Customer.io and using structured questions plus purchase verification, you can build cleaner segments and more relevant journeys powered by first-party data rather than assumptions.
-
Support Email and SMS Workflows: Collecting phone numbers early gives you the option to support SMS automations and SMS touchpoints as part of a wider customer engagement workflow. This makes the customer profile more useful beyond email alone.
-
Increase Engagement Across the Funnel: A better-structured audience can support stronger open rates, click-through rates, and overall engagement because subscribers receive more relevant content. Better profile structure also helps reduce friction in your workflow by giving you a more targeted audience for campaigns and journeys.
-
Strengthen the Full Customer Journey: This template helps turn a giveaway into a complete customer engagement workflow by improving lead quantity, first-party data quality, segmentation, personalisation, upsell readiness, cross-sell opportunities, SMS readiness, and downstream conversion potential.

How to Set Up Your Customer.io Cross-Sell and Upsell Giveaway
-
Set Up the Campaign Basics
Start with this template, then update the campaign title, dates, and prize so the promotion matches your audience and your list-growth objective.
➡ Learn how to set up your competition -
Configure the Pre-Entry Fields
Open the Pre-Entry tab and add the subscriber fields you want to collect before entrants unlock the campaign actions. Start with useful built-in fields such as first name, last name, country, phone, and company, then add custom fields where needed for current setup type, budget range, customer type, or other segmentation data.
➡ Learn how to use custom fields -
Enable the Competition Subscriber List
Turn on Build Competition Subscriber List if you want Gleam to keep an internal subscriber list alongside your Customer.io integration. This can help you manage entrant data inside the campaign as well.
➡ Learn how subscriber collection works -
Connect Customer.io and Map Your Subscriber Fields
In the Subscribe to Newsletter action, connect Customer.io and choose the audience or destination where new subscribers should be added. After that, open the custom field mapping settings and map your competition fields to the matching Customer.io fields. This is important because it lets you pass data such as first name, phone, country, company, current setup type, budget range, customer type, wishlist intent, buying motivation, or invoice-related details into Customer.io instead of only sending an email address. By mapping these fields properly, you can improve segmentation, personalise journeys, and create more useful email and SMS follow-up.
➡ Set up the Customer.io integration -
Add the Campaign Actions
Build the action stack around your main email growth objective. Use the mandatory Subscribe to Newsletter action as the highest-value conversion step, then support it with a motivation-based multiple choice question, relevant product visit actions, a wishlist action to capture future purchase intent, selected social follow actions, a custom invoice number action for existing customers, a viral share action, one secret code action tied to your welcome email, and a second secret code action delivered via SMS. Finish with a Bonus action at the end of the stack to reward entrants who complete all previous actions.

Use the Question and Invoice Responses for Segmentation and Journeys
Use the answers from your motivation-based question together with wishlist intent and invoice details to classify subscribers inside Customer.io.

Customise the Campaign Design
Use the approved Customer.io-inspired colours, a strong prize-led heading, and a short entrant-facing description that clearly explains the key actions and incentive. -

Share the campaign across your website, social channels, paid traffic, and existing customer touchpoints.
