Chatlane: send a WhatsApp campaign

1. Open Campaigns › New campaign.
2. Choose the Sender number and the Audience (one or more labels, or everyone who opted in).
3. Write the message. Personalise with {name}, {phone} and {unsubscribe}. Add an image, video, audio or document if you like.
4. Set the schedule (time follows your profile time zone) and the Interval between messages — at least 60 seconds keeps your number safer.
5. Save. Watch progress in Reports & statistics; pause, resume or cancel any time.

Each sender has a daily limit (Free is lower; Pro and fred.my Unlimited are much higher).
