Schedule WhatsApp messages for appointment reminders, customer follow-ups, event reminders, order updates, delivery notices, product availability updates, and other permission-based communication. ## WHATSAPP MESSAGE TEMPLATES Pro users can save reusable WhatsApp message templates and campaign configurations.

Campaign Review can display: * Intended recipients * Valid and excluded contact totals * Message content * Selected attachment * Delay configuration * Relevant warnings During a campaign you can follow: * Sent * Pending * Failed * Invalid * Skipped A pending message is not automatically presented as a confirmed send when the active web session has not yet returned a final status. You can also view the current contact, campaign progress, next-message timing, and export campaign activity to CSV. ## ONE-CLICK RETRY FOR FAILED MESSAGES When eligible messages fail, WA Sender HQ can prepare a retry campaign containing only eligible failed attempts. Successful contacts are not added to the retry queue. Invalid, suppressed, pending, and intentionally skipped contacts remain excluded where appropriate. This helps reduce accidentally sending the same message again to recipients who already received it. ## DO NOT MESSAGE LIST Maintain a local Do Not Message suppression list for contacts who should not receive future campaigns. Numbers on the list are automatically excluded from: * Immediate campaigns * Scheduled campaigns * Eligible failed-message retries Contacts can be added individually or pasted as a list.
