We are launching Zapier Integration for PRO plan users. This will now allow you to connect external services like RSS, Facebook, Twitter feed etc. and directly update your subscribers.
The Zapier integration is in beta and contact support to get your API key.
Connect your PushOwl account by entering the API Key provided by us.
Enter your subdomain. For Shopify Stores, if your store URL is "xyz.shopify.com" then your subdomain is: "xyz". You can connect the rest of the fields based on your source.
And you should be good to go. Contact us if you need any help.
