A complete walkthrough of creating, managing, and analyzing AI-powered bulk call campaigns from the OmniDimension dashboard. ## Prerequisites [#prerequisites] Before creating a bulk call campaign, you need to set up your phone number and deploy an AI agent. * Navigate to the **Phone Numbers** section from your dashboard * Import a phone number (e.g., Twilio, Exotel) * Ensure your agent is properly configured with context, instructions, and integrations * Attach the agent to your imported phone number * Test your agent with a single call before running bulk campaigns ### Deploy an agent with a phone number [#deploy-an-agent-with-a-phone-number] Deploy agent with phone number ### Agent successfully attached [#agent-successfully-attached] Agent attached confirmation ## Creating a bulk call campaign [#creating-a-bulk-call-campaign] The bulk call creation process is divided into 4 steps. Navigate to the **Bulk Call** section from your dashboard and click **Create New Campaign** to begin. ### Campaign details and phone number selection [#campaign-details-and-phone-number-selection] Set up your campaign name and choose the phone number with attached agent for making calls. * Enter a campaign name. Use descriptive names for easy tracking (e.g., "Q4 Product Launch Outreach") * Select a phone number from the dropdown * Review the agent details displayed automatically, including integrations and post-call actions * Verify the agent configuration is correct for your campaign goals * Click **Next** to proceed to Step 2 Step 1: Campaign details ### Upload contact list and CSV configuration [#upload-contact-list-and-csv-configuration] Upload your contact list in CSV format and configure call conditions. * Click **Upload CSV File** and select your contact list * The system will automatically detect columns and validate the format * Review the preview of your uploaded data * Set optional call conditions to filter which contacts to call * If missing variables are detected, download the template and add required data Step 2: Upload CSV #### CSV format guidelines [#csv-format-guidelines] * Required column: `phone_number` (with country code, e.g., 1, 91) * Optional columns: `name`, `company`, `reason_for_call`, etc. * Column names should match variables in your agent's context or welcome message * Additional columns are automatically passed as context to the AI agent * Maximum file size: 10 MB * Supported format: `.csv` files only * Download the provided template and add the required data columns to ensure optimal agent performance ### Campaign settings and scheduling [#campaign-settings-and-scheduling] Configure when to start your campaign and set up advanced features like auto-retry and call rescheduling. * Choose when to start: **Start Immediately** or **Schedule for Later** * If scheduling, set the date, time, and timezone * Configure Auto Retry settings for failed calls * Enable Call Rescheduling to automatically handle callback requests * Click **Next** to proceed to Step 4 Step 3: Campaign settings #### Configuration options [#configuration-options] Detailed configuration #### Auto retry settings [#auto-retry-settings] * **Maximum Retry Attempts**: Set retry limit (1–6 attempts maximum) * **Retry Schedule Immediately**: Retry failed calls right after the main campaign completes * **Retry Schedule Next Day**: Automatically retry all failed calls the following day * **Retry Schedule Scheduled Time**: Set custom days and hours delay for retry attempts * Auto retry only triggers after the main campaign completes * You can edit retry settings even after campaign creation #### Call rescheduling [#call-rescheduling] * Enable **Call Rescheduling** in campaign settings * AI automatically detects customer requests like "call me tomorrow" or "I'm busy right now" * Automatically schedules follow-up calls based on customer preferences * Works by analyzing conversation for reschedule requests during the call * Improves customer experience and conversion rates ### Review and create campaign [#review-and-create-campaign] Final review of all campaign settings before creation. * Review all campaign details: name, phone number, and agent configuration * Check the number of contacts to be called * Verify scheduling settings (immediate start or scheduled time) * Confirm auto-retry settings and maximum retry attempts * Check estimated cost and ensure sufficient account balance * Click **Create Campaign** to launch or schedule your bulk call campaign Step 4: Review and create ## Campaign management after creation [#campaign-management-after-creation] Once your campaign is created, you can monitor, control, and analyze its performance. * **Pause Campaign**: Temporarily stop an active campaign * **Resume Campaign**: Continue a paused campaign * **Update Reschedule Settings**: Enable / disable call rescheduling during campaign * **Update Auto Retry Settings**: Modify retry attempts and schedule Campaign management interface ## Best practices for successful campaigns [#best-practices-for-successful-campaigns] * Test with a small batch first before launching to your entire list * Use descriptive campaign names: include date, purpose, and target audience for easy tracking * Include relevant context columns that match your agent's variables for personalized conversations * Set appropriate retry limits: 2–3 retry attempts are usually optimal * Enable call rescheduling to improve success rates and brand reputation * Check progress regularly and adjust settings based on real-time performance * Use campaign analytics to improve future campaigns and agent performance See [Bulk outbound best practices](/docs/bulk-calls/best-practices) for the full optimization playbook.
