Sending 1,000 promo messages by hand takes a full day, and WhatsApp may treat it as spam. Then there's the copy-pasting and changing names one by one.
Upload your contact list, write the message with a name placeholder, and set the send time. The system sends in turns with random delays. Thousands of messages go out within a few hours.
What it does
Personal messages, automatically
Use {name}, {city}, and {last_product} placeholders. Every recipient sees their own name.
Paced sending queue
Messages go out with random delays at a controlled speed, which lowers the risk of your number being flagged as spam.
Scheduled sends
Monday at 9am or Saturday at 7pm. Set the time and the system sends it.
Audience segments
Send only to contacts with certain labels, like "VIP", "Never purchased", or "Follow-up patient".
How it works
Choose recipients
Pick from your contacts: everyone, or filter by label, last activity, or location.
Write the message and attach files
Write the message with placeholders. Attach images, video, or a PDF if needed.
Schedule and send
Send now or later. Track how many were delivered, read, and answered.
Where it fits
Weekend promo for an online store
Send a 24-hour promo to 3,000 customers on Friday night. On Saturday morning, check how many replied and how many ordered.
Check-up reminders for clinic patients
Send to contacts labeled "check-up this month": "Hi {name}, it's time for your check-up. Which day works for you?"
Reaching past rental or service customers
Customers who haven't rented or booked a service in 60 days get a special offer. Anyone who replies lands in the inbox.
