What are roadblocks?

Roadblocks allow you to exclusively serve ads from selected campaigns on all zones on a web page or newsletter. For more information, read How to create a roadblock.

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, AdButler 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 user must have a unique EUID.

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 instance.

Here's an example of an email zone tag with place:

<!-- AdButler Email Zone [email] -->
<a href="https://servedbyadbutler.com/go2/;ID=180028;size=300x250;setID=466368;uid=Your Email Unique Identifier Here;click=CLICK_MACRO_PLACEHOLDER" target="_blank">
<img src="https://servedbyadbutler.com/adserve/;ID=180028;size=300x250;place=0;setID=466368;type=img;uid=Your Email Unique Identifier Here;" width="300" height="250"></a>

The second instance of this zone in a newsletter would then be:

<!-- AdButler Email Zone [email] -->
<a href="https://servedbyadbutler.com/go2/;ID=180028;size=300x250;setID=466368;uid=Your Email Unique Identifier Here;click=CLICK_MACRO_PLACEHOLDER" target="_blank">
<img src="https://servedbyadbutler.com/adserve/;ID=180028;size=300x250;place=1;setID=466368;type=img;uid=Your Email Unique Identifier Here;" width="300" height="250"></a>
