Yes. You can use weather in your email, SMS and marketing automation campaigns in three ways.
Salesforce Marketing Cloud
WeatherAds updates your Salesforce data extensions with a live True or False value for each location. Use these values to segment audiences, personalise content or trigger customer journeys when the weather matches your rules.
To connect, go to Connected Accounts, choose Salesforce Marketing Cloud and enter your API credentials (Login URL, REST URL, Client ID, Client Secret and Account ID). Salesforce Marketing Cloud is included on the Enterprise plan.
Zapier
A Zapier automation sends a live True or False value to your Zaps. Use it with Mailchimp, Klaviyo, HubSpot, ActiveCampaign or any other app Zapier supports.
Webhooks
A Webhook automation posts the same values to any URL, for platforms that accept incoming data.
Zapier and Webhook automations are limited by plan: 2 on Economy, 10 on Growth, and custom limits on Premium and Enterprise.
