Managing Contacts

The Contacts directory in Rayo SMS lets you manage your recipient address book, associate customer reference IDs from your CRM or ERP, and control delivery suppression using the Invalid? flag.

To access your contacts, sign in to the Web Application and click Contacts in the left sidebar.

First Name	Optional	The contact’s given name.
Last Name	Optional	The contact’s surname / family name.

Suppressing Delivery with the “Invalid?” Flag

When a contact has the Invalid? (is_it_invalid) checkbox enabled, Rayo SMS automatically skips and suppresses SMS delivery to that mobile number.

Automatic Suppression Across Group Campaigns

Marking a contact as Invalid blocks messages to that number even when you send a bulk campaign to a Contact Group that still contains the contact.

This makes the Invalid? flag ideal for managing:

• Customer opt-outs / unsubscribes (GDPR and marketing compliance)
• Known disconnected or deactivated numbers
• Temporary delivery holds without losing the contact’s historical record, reference ID, or group memberships

Deleting a Contact

To permanently remove a contact from your account, click Delete Number next to the contact.

Deleting Removes Group Memberships

Clicking Delete Number permanently deletes the contact from your Contacts list and automatically removes the number from every Group it belongs to.

If you only want to remove a recipient from a single group while keeping them in your Contacts database, remove them from the Group’s member list instead. Or, if you want to prevent accidental delivery across all future imports and campaigns, mark the contact as Invalid? instead of deleting it.
