What are roadblocks?
Roadblocks allow you to exclusively serve ads from selected campaigns on all zones of a website or newsletter. For more information, read Understanding Roadblocks.
Roadblocks in email zones
In newsletters, the campaign that is chosen to serve in the first zone will enforce its roadblock.
Because JavaScript is disabled in email zones, Indie Ads Manager relies on the Email User ID (EUID) to see if a newsletter is serving ads in multiple zones. This is one of the reasons why each use must have a unique EUID. Learn more about serving ads to your email platform.
If the EUID is configured correctly, roadblocks will work as intended on existing email zones.
Using the same zone multiple times in a single newsletter
To use the same zone in a newsletter multiple times, add a place parameter in the image tag of the email zone tag. The parameter's value should be 0 for the first instance of the zone, and incremented by one for each subsequent use.
Tag Edit Example
Here's an example of an email zone tag with place:
<!-- Email: Mobile Interstitial [email] -->
<a href="https://servedby.indiegraf.com/go2/;ID=185279;size=320x480;place=0;setID=715848;uid=%SUBSCRIBERID%%MESSAGEID%;click=CLICK_MACRO_PLACEHOLDER" target="_blank"><img src="https://servedby.indiegraf.com/e061c2b60/img-api/O0lEPTE4NTI3OTtzaXplPTMyMHg0ODA7c2V0SUQ9NzE1ODQ4O3R5cGU9aW1n/?uid=%SUBSCRIBERID%%MESSAGEID%" width="320" height="480"></a>
The second instance of this zone in a newsletter would then be:
<!-- Email: Mobile Interstitial [email] -->
<a href="https://servedby.indiegraf.com/go2/;ID=185279;size=320x480;place=1;setID=715848;uid=%SUBSCRIBERID%%MESSAGEID%;click=CLICK_MACRO_PLACEHOLDER" target="_blank"><img src="https://servedby.indiegraf.com/e061c2b60/img-api/O0lEPTE4NTI3OTtzaXplPTMyMHg0ODA7c2V0SUQ9NzE1ODQ4O3R5cGU9aW1n/?uid=%SUBSCRIBERID%%MESSAGEID%" width="320" height="480"></a>
