Batch send
Sends the same message to multiple numbers, one at a time with a short delay between each to reduce carrier throttling risk. Select devices below and/or paste extra numbers (one per line) not yet saved as devices.
Settings — phone gateway
Use the SMS Gateway for Android app, or paste a MacroDroid Webhook URL directly into the IP address field to send SMS instantly via MacroDroid (e.g., https://trigger.macrodroid.com/YOUR_ID/sendsms).
Receiving SMS (webhook)
Enter this computer's address as the phone sees it (same Wi-Fi network), then register the webhook so the phone pushes incoming SMS here.
