Conversations vs. Campaigns

The HelloSMS platform supports two main communication modes: one-to-one Conversations and Campaigns (Group Messages).

One-to-One Conversations (Two-way SMS)

This is for interactive, two-way communication with individuals, like using your personal phone messenger.

To start a one-to-one message, enter or select an individual number in the recipient field on the Send SMS page.

See Send an SMS to learn more about adding recipients to an SMS message.

Best For: Customer support, quick follow-ups, and internal communication.
Location: All messages and replies live in the Conversations tab as continuous threads.

This method is ideal for high-volume, one-to-many outreach such as marketing or mass announcements.

Create Campaigns automatically by selecting a list of numbers in the recipient field on the Send SMS page.

See Create a Contact List to learn how to create a list of numbers to start campaigns.

Best For: SMS marketing and sending official or transactional messages to a list.
Location: Messages are grouped in the dedicated Campaigns list. Numbers only appear in the Conversations view if you receive a reply.

Other features:

An automatic opt-out (unsubscribe) option is included by default for compliance. See Unsubscribe Text Overview to learn more.
A contact in multiple lists receives the message only once (to remove duplicates).
