A drip campaign in HelloSend is a scheduled sequence of SMS or WhatsApp messages that automatically sends to a contact based on a trigger (e.g., a new ticket, lead created, status changed). You design the sequence as steps with delays and templates. HelloSend fires the sequence via a webhook you connect to your CRM's automation (Zendesk/Zoho CRM/HubSpot, etc.).
Common uses: new-lead welcomes, no-reply follow-ups, appointment reminders, onboarding nudges, renewal prompts.

2Configure Basics for HelloSend Drip Campaigns
- Name: Assign a clear and descriptive name (e.g., Welcome Message) so campaigns are easy to identify.

- Phone Field: Specify the exact phone field from your CRM record that HelloSend should use for message delivery.
3Build Your Steps in HelloSend Drip Campaigns
When creating a drip campaign in HelloSend, you can design a sequence of automated SMS or WhatsApp messages that run on a schedule. Each step can be customized with its own delay, template, and reply handling rules.
- Step 1 Send a welcome message immediately after the trigger or add a short delay. Choose a saved template for consistent communication.
- Step 2 Create a follow-up message (e.g., after 1 day) to re-engage the customer.
- Reply Handling At any step, you can enable the option to stop the campaign if the customer replies, preventing unnecessary or duplicate follow-ups.
- Activation Once all steps are configured, click Save to activate your drip campaign and start automating customer engagement.
