Contacts

Creating a contact list is easy. You can upload a list of numbers from a spreadsheet or add them manually, one by one. When you upload your opted-in contacts, you can include first and last name, among other fields, to customize outgoing messages. You may also sort, segment and update your list of unlimited contacts. View our uploading guide.

Contacts are automatically tagged by their opt-in source if they were obtained using one of our signup widgets, but you can further segment your contacts into unlimited Groups. Once you've done this, you can send your messages to a single or multiple groups. And don't worry about sending your message to a contact twice if they're in multiple groups - our duplicate checker makes sure that never happens.
