General questions
No that’s not possible. Just as we do not share your data with the networks, they do not share the data they have with us. We get the reporting on the campaign level, not the contact level.
Yes, on the network. All networks have mechanisms whereby people can opt out from receiving ads from the advertiser.
Not necessarily. The networks will automatically exclude the users in the source audience, but it does not check to see if the users it selects for the lookalike audience are already in your database (or indeed in another custom audience). It is therefore possible that some existing contacts will also appear in lookalike audiences. To avoid this, when launching the Ads campaign from within the network you should explicitly exclude all your other audiences.
You can create up to 100 audiences per Emarsys account and an audience may contain a maximum of 20 million contacts. If you require more audiences than this, Emarsys Support can increase the limit for you.
Your audiences are restricted only by the thresholds set by the network before they can be targeted (Facebook, 1,000 contacts and Google, 1,000 contacts).
To keep your ads budget spend optimally targeted, you should always think about removing a contact from an audience once they have converted, as shown in the blueprint Remove converted contacts from ads.

It can take the networks a few hours to match an audience once it has received a request (though this usually happens much faster). Emarsys sends audience updates:
- In real time, if a contact is added to an audience through the Automation Center.
- Daily for segment audiences.
You can create up to 100 audiences in total, and an audience may contain up to 20 million contacts.
However, the daily sync of segment-based audiences is limited to 20 million total contacts (contacts appearing in multiple audiences are counted multiple times). If the number of contacts in your segment audience reaches 80% of this value (i.e. 16 million contacts), a warning will be displayed. If the number of contacts in your segment audience reaches 110% of this value (i.e. 22 million contacts), sync will stop and you will receive a notification. In this case, no audiences are synced and the daily routine will only resume when the total has fallen below 22 million.
The total of 100 audiences includes the archived audiences. If you run out of audiences, either delete unused audiences in the UI or contact Emarsys Support to increase your limit.
The cost of media is not included and billed separately by Facebook and Google. Your network ads accounts will connect to Emarsys with your credit line. The minimum budget will depend on your use case and the amount of contacts you are expecting to target, but given that you are limiting targeting to just your own customers, the media budgets are relatively small.
This status means that the network is processing the successfully transferred audience.
- For Facebook this process may take up to 1 hour to complete.
- For Google it can take up to 24 hours to complete.
This status is only shown for segment audiences.
You will authorize the CRM Ads app to access your existing Facebook or Google Ads account to create and manage audiences on your behalf. Billing is handled directly between you and the network.
Questions specific to Facebook
There is currently no capping functionality available within Emarsys, but Facebook restricts the Newsfeed ads(desktop and mobile) to 2-3 impressions per user, per day. Therefore, if you exclude Right-side ads from your campaign, you will automatically have this default capping in place. If you include Right-side ads, you cannot control how many ads the users will see in total.
Facebook Custom Audiences is a Facebook targeting solution that allows a marketer to match their own contact lists to user profiles in Facebook. CRM Ads takes this functionality and seamlessly integrates it into the Emarsys platform, meaning you can:
- Use the sophisticated segmentation of Emarsys (customer lifecycle stages, email responses, purchase and browse history, etc.) to create highly specific micro-segments.
- Create your ads and audiences within Emarsys, ensuring consistent messaging across all channels.
- Use the Automation Center to add Facebook to your automated engagement campaigns, adding contacts to audiences in real time based on their behavior, and removing them again afterwards.
Improve your ROAS (Return On Ad Spend) by only targeting contacts at specific times, and for shorter duration, with highly personalized content matching their customer lifecycle stage at precisely that moment.
What this means is that CRM Ads takes the basic premise of Facebook Custom Audiences – locate your customers on Facebook and engage with them there – and turns this into real-time, 1-to-1 targeting.
The price for CRM Ads includes connecting to one Emarsys account. You can connect to more, but there will be additional costs; please contact your Success Manager.
