The short answer is:
The reason the `absoluteURL` and related fields are failing is likely because they refer to the email’s original staging URL, which is deactivated or changes after the email is sent, leading to the 404 error you see.
The actual public “Website Version” URL is not a standard, persistent property directly on the email object in the HubSpot API or the Snowflake table.
The most robust and scalable way to solve this is by using the HubSpot API to trigger the generation of a new, persistent web version URL upon sending, and then immediately pushing this URL to Salesforce via the Salesforce API to be associated with the contact’s email activity 
The long answer is:
Your idea of getting the public “Website Version” URL to display the email content for your sales reps is excellent, as that specific URL is designed to be a permanent, shareable link to the email’s content as it was sent.
The issue is that the `absoluteURL`, `publishedURL`, and `URL` fields you see are typically internal links or temporary preview links that are not designed to be public-facing or persistent after the campaign is completed, which explains the 404 errors 
To fix this, you need to execute a process that HubSpot does not handle automatically.
The better and ultimately cheaper solution than constant manual data uploads or debugging temporary URLs is to create a small, automated service that uses the HubSpot API and the Salesforce API.
This service would be triggered upon the marketing email being sent.
You would use the HubSpot API’s functionality to not just read the email details but to also generate and retrieve the stable, public “View in Browser” URL.
Once you have this unique, persistent URL for a given email campaign ID, you use the Salesforce API to push this URL into a custom field on the Salesforce Email Message object or a related Activity record type.
This way, every time a rep sees an “Email Clicked” activity, the specific Website Version URL is right there, clickable, providing the content they need.
Using a server-side environment like Stape or Google Cloud Platform allows you to host this small automation script without needing expensive traditional hosting.
Furthermore, managing the trigger and data flow via Google Tag Manager (for any related web-to-CRM logic) helps create a centralized, reliable, and auditable data exchange between HubSpot and Salesforce, avoiding the limitations and inconsistencies of the default connector for this specialized task.
This provides a permanent, low-cost fix that works for every future email, solving the problem at its root
