The four shopper signals your welcome flow should notice first

Most welcome flows start with the same assumption: every new subscriber needs the same introduction, the same discount, and the same urgency. The store already knows more than that. A shopper's first few clicks usually tell you whether they are comparing, impulse buying, gift shopping, or trying to trust the brand.

You do not need a complex prediction system to make the first version better. Start with the highest-signal behaviors that are already available from your storefront and pass the resulting intent into Klaviyo as a simple profile property or event.

1. Depth of research

Multiple product, collection, guide, or ingredient-page views before signup usually means the shopper is still building confidence. These people need proof, comparison help, founder context, and objection handling before another coupon.

2. Cart speed

A cart action within the first session is a very different moment. The buyer is close. A concise welcome, free-shipping reminder, or product-specific nudge will often fit better than a long brand story.

3. Category intent

If a shopper stays inside one category, the first email can mirror that language. A skincare shopper researching sensitive-skin products should not receive the same examples as someone browsing bundles or gifts.

4. Offer sensitivity

Repeated sale-page or discount-code behavior is a useful clue, but it should not be the only branch. Discount-first messaging can train full-price buyers to wait. Treat offer sensitivity as one signal among several, not the default story for everyone.

• Keep the first rule set readable enough for a founder to approve.
• Write every intent label in plain English so your email copy can use it.
• Review the rules monthly as new products, guides, or campaigns change shopping behavior.

The goal is not to make welcome email complicated. The goal is to stop ignoring the behavior your store already saw before the form submit happened.
