What does the Subworkflow: Check Email Address Against Free Providers List Crate do?

Use this subworkflow in your workflows to determine if a provided email address is from a free provider.

How the Crate works

This Crate is a little different from most of our other Crates. It contains a subworkflow you can use in building your own workflows rather than a fully-executable workflow that achieves a goal right after unpacking.

The subworkflow downloads a list of free providers according to HubSpot's knowledge base and checks the email address against that list.

Input: email_address - string email address to check

Output: free_provider - boolean of whether the email provided is from a free provider

Workflow breakdown

1. The workflow begins when triggered with an email address input parameter that needs to be checked against a list of free email provider domains.

2. The set_domain task executes first using the noop action to extract the domain portion from the provided email address by splitting on the @ symbol, taking the last part, and converting it to lowercase, then publishing this value as email_domain to the workflow context.

3. The get_list_of_free_provider_domains task runs in parallel using the HTTP Request action to retrieve a CSV file containing free email provider domains from a HubSpot URL, then processes the response by splitting the data on newlines and trimming whitespace from each domain, publishing the resulting list as free_domains to the workflow context.

4. After both the set_domain and get_list_of_free_provider_domains tasks complete successfully, the check_list task executes using the noop action to perform the actual comparison by checking if the extracted email domain exists within the list of free provider domains.

5. The check_list task publishes a boolean result as free_provider to the workflow context, indicating whether the provided email address uses a free email provider domain or not.

6. The workflow completes by outputting the final result through the free_provider variable, which contains true if the email address uses a free provider domain or false if it uses a non-free domain.
