Weather-triggered campaigns for Shopify

Weather drives buying decisions.
Your business is not triggering on it.

Sunscreen sells in heatwaves. Jackets sell before the cold front comes. Weathercop checks the forecast for your customers’ cities. When your conditions are met in the coming days, it sends a Klaviyo event with the products you picked, and your Klaviyo flow sends the email.

Weather variables

Conditions you set, checked against the daily forecast for each supported customer city.

  • Temperature

  • Precipitation

  • Snowfall

  • UV Index

  • Wind speed

  • Humidity

  • Weather condition

The Problem

Weather shapes what your customers need. Your email probably doesn’t follow it.

For entire product categories — outdoor gear, sun care, beverages, garden, beauty — local weather changes what people need next. A heatwave sells sunscreen. A cold front sells jackets.

Larger retailers already run weather triggers on enterprise marketing platforms.

For most Shopify brands, that tooling has never been within reach — so seasonal campaigns go out on the calendar, not on the forecast in each customer’s city.

Weathercop changes that.

Campaign experience

Two brands. Two weather-triggered campaigns.

Weather-triggered email campaigns our team has built and run. Weathercop brings that experience to Shopify and Klaviyo.

OUTDOOR APPAREL · CASE STUDY 01

Rain-triggered campaign

Weather-triggered email · Bloomreach

A premium European outdoor apparel brand paired a local rain forecast with hardshell jackets.

The Trigger

Rain forecast in a customer's location → hardshell jacket campaign featuring waterproofing technology.

HEALTH RETAIL · CASE STUDY 02

UV-triggered campaign

Weather-triggered email · Bloomreach

A US online marketplace for health and personal care products ran a UV-triggered campaign.

The Trigger

UV index ≥ 8 OR forecasted high ≥ 90°F in a customer's ZIP → sun protection and cooling product campaign, with the city name and forecast numbers in the subject line (e.g. 'High UV in {{ location }}').

Michelle · Lifecycle Marketing Manager

On a weather-driven email campaign.

Read Michelle’s full testimonial

I had the pleasure of collaborating with Daniar on a campaign that used weather-driven data to increase personalization through our email channel. This enabled us to deliver timely, relevant content to customers tailored to their local temperature and UV index. It was unlike any campaign we had launched before, and it was a clear success, driving increased conversions and helping us to achieve our revenue goals. Daniar brought expert level strategy and technical acumen that allowed for a seamless campaign launch. If you’re looking to elevate your email marketing strategy, I highly recommend leveraging forecasted weather data to deliver next-level personalization.

Five steps from install to first send.

No data engineering. Built for Shopify and Klaviyo.

  1. 01

    Install the app

    Weathercop syncs your customers and their marketing consent from Shopify, and matches each customer to their city's forecast. Weathercop works by city, and we confirm which of your customers' cities are covered during onboarding.

  2. 02

    Set your conditions

    Start from built-in scenarios like hot and sunny, rain, or snow and ice, or set your own thresholds for temperature, rain, wind, humidity and UV. A cooldown on each trigger keeps customers from hearing about the same weather too often.

  3. 03

    Choose your products

    Pick up to 10 products from your Shopify catalog for each trigger, in the order you want them shown.

  4. 04

    Build the email in Klaviyo

    Connect Klaviyo, then build a flow that starts from the Weathercop event. The event carries the customer's city, the forecast and your products, so the email can be written in your brand and your voice.

  5. 05

    Send automatically

    Weathercop checks the forecast every day. When your conditions are met in a customer's city in the coming days, it sends the event to Klaviyo and your flow takes it from there, alongside the campaigns you already run.

Turn the forecast into a reason to buy.

Weathercop helps you reach customers with products that fit the weather ahead. Let’s find the conditions and products that make sense for your store.
