Your own Sender ID
Set any sender name you want, up to 11 alphanumeric characters. No pre-approval, no waiting, no follow-up questions. Change Sender ID between campaigns or use different IDs per segment for A/B testing.
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.
Support that answers
We operate from Sweden. Ping us and a technician answers — not a chatbot, not a tier-1 agent escalating. Directly to someone who knows the system.
