Please be aware that WhatsApp messages sent via zkipster will not be delivered to phone numbers registered with WhatsApp in the United States. This restriction stems from Meta’s current limitations on message templates for US-based users. Specifically, starting on the 1st of April 2025 Meta has placed a hold on delivering marketing template messages—including invitations, promotional messages, or similar communication—to users in the US due to ongoing policy and regulatory considerations.

This limitation is enforced by WhatsApp’s Cloud API, and affects all third-party platforms using it to send messages, such as zkipster. As a result, even if your WhatsApp message campaign is compliant and well-formatted, it will not reach recipients with US phone numbers. We recommend using alternative campaign templates such as email or SMS for reaching your US-based invitees until Meta lifts this restriction. You can read more about this policy on Meta's developer documentation.
