Issues Sending Contact Cards in Campaigns

   Tip: Select any of the images or GIFs in this article for a closer look.

Contact cards are a great way to identify your brand as trusted within a phone messaging app, preventing messages from being flagged as spam. They're also a great way to introduce your brand to your subscribers so they see that your brand is messaging them and not an unfamiliar number.

The Issue


Messages containing contact cards that are sent via a dedicated short code are experiencing inconsistent delivery rates, particularly on Verizon and T-Mobile. This is especially common in larger campaign sends (20,000+).

Carriers limit the number of contact cards that you can send in a campaign. Carriers may not deliver your campaign if you are sending a contact card to a large number of subscribers.

We are actively working with our partners to improve the deliverability rate and will update our customers once we’ve reached a solution.

How Postscript Notifies You


We understand that for many brands, sending a contact card to their subscribers is a key part of building rapport and trust.

You can still include a contact card in campaigns, but doing so will display the following notification:

The notification reads:

Carriers limit the number of Contact Cards that you can send in a campaign. Carriers may not deliver your campaign if you are sending a Contact Card to a large number of subscribers. We recommend only including Contact Cards in campaigns to 20,000 or fewer subscribers, or including Contact Cards in Automation and Keyword replies. 

Alternative Approaches to Sending Contact Cards to Your Subscribers


  • Consider a smaller send group. We have seen more successful contact card deliverability in campaigns containing less than 20,000 messages.
  • Include contact cards as part of an automation series, such as your welcome series.
  • Include contact cards as part of your keyword replies.
