You might want to include external HTML from other websites within your campaigns.
You can do it using a special dynamic tag:
**|external_url1|**
Configuration for the external url is done at content level within the dashboard. It can include dynamic tags like user email or user ID that will be replaced for each request.
For example:
https://api.example.com/return_html/**|user.email|**/**|campaign.id|**How does it work:
When email is processed to be delivered, we load the external URL beforehand and embed the response within the content where the dynamic tag was placed.
Conditions:
- response time must be less than 0.5 seconds.
- status code for the response must be 200 or 201
- for any other situation, the tag is replaced with empty string.
