Frequently asked questions
Direct answers to engineering and legal questions.
We provide communication infrastructure β just like a hosting provider or CRM. The client is responsible for the legitimacy of their database and message content. We do not work with prohibited content and require confirmation that the database was legally collected.
If our number is blocked ("Our number" plans), we replace the slot free of charge within 24 hours. A new SIM costs $5. The unused limit balance carries over.
Web emulators and server-side solutions are detected by messengers via digital fingerprint within 24β72 hours. Our infrastructure uses real smartphones with mobile carrier IPs. This is not "bypassing blocks" β it is operating under the same conditions as a regular user. Shared uses a common channel pool; Dedicated provides a dedicated channel, device, and queue.
Shared has no monthly fee at all: you pay only for delivered messages. Notify, Connect, and Dedicated are fixed per-channel subscriptions because you get predictable volume, priority, and (in Dedicated) a dedicated device. No hidden charges for conversations.
Yes. Trial period β 3 days with a reduced limit (up to 500 messages) or a one-time test broadcast to your segment. Terms are discussed individually.
At 300/hour, one stream delivers up to ~20,000 per month (accounting for number validation and pauses). For larger volumes we connect additional streams β pricing is calculated individually.
Yes. Statuses are available in the dashboard and via API: Sent / Delivered / Read. The "Read" status depends on whether the recipient enabled read receipts β this is a WhatsApp/Viber limitation, not ours.
Yes, in Connect and Dedicated. Incoming messages arrive via webhooks to your CRM or AI. Notify does not include reply reception β that plan is designed for one-way notifications. Shared supports replies, but the channel is shared.
We operate on distributed infrastructure with multiple pools of devices and carriers. Blocking one pool does not stop the others. In a force majeure event, we migrate clients to backup capacity.
For $20 you usually get web emulators or server-side solutions with account lifespan of 1β3 days. Our Shared has no monthly fee at all, and Dedicated is a dedicated channel and device. Calculate the cost per delivered message, not per subscription.
For client numbers we recommend the "Smart Number Validation" option (+$15/mo). It filters inactive numbers before sending and reduces the risk of blocking your corporate account. We also throttle speed to a safe pace.
We guarantee delivery to the messenger and record statuses. Beyond that is WhatsApp/Viber territory: if the recipient blocked the sender or deleted the account, the message will not arrive. Delivery statistics are visible in real time.
