Compliance without friction

Automatic opt-out via STOP/AVSLUTA, quiet hours per market and content warnings that catch carrier-risk content before you send.

Crypto and card payments

Top up with BTC, ETH or USDT via NOWPayments, or by card through Banxa. Balance is available as soon as payment is confirmed — usually within 60 seconds.

Delivery rate that holds

Direct connections to Telia, Telenor, Tre and Tele2 provide stable delivery to Swedish numbers. Real-time DLR shows exactly which SMS were delivered, pending or bounced — nothing sits in dark queues.

Real-time analytics

See delivery rate, click rate, opt-outs and revenue per campaign in real time. Segment by operator, geography and time of day — then export to your data lake with webhooks or CSV.
