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.
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.
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.
Frequently asked questions
How is opt-out handled?
Automatically through STOP/AVSLUTA — the customer is placed on a per-sender blocklist. You can also whitelist.
Do I need KYC or verification?
No. Sign up, top up and send. No forms, no application, no waiting.
Can I send OTP?
Yes. Low latency, high queue priority and separate throughput limits for transactional SMS.
Can I schedule campaigns?
Yes. From the dashboard or API, including timezone-aware scheduling and batch sends.
Can I choose any Sender ID?
Yes. Set any sender name you want, up to 11 characters. We do not pre-review Sender IDs for you.
Is SMS content logged?
Metadata is logged for DLR and support. Message content can be pseudonymized or deleted on request.
