What this market refuses

One API

How sending works

You send to every destination through the same endpoint and the same keys. Bird picks a compliant route for the country, applies opt-out handling on every message, and reports delivery from carrier receipts. The country-specific part is which sender you register. The API call does not change.

Sending to Bulgaria, answered

Can I use an alphanumeric sender ID in Bulgaria?
Yes, once the sender ID has been registered.
Can I receive replies from Bulgaria?
No. You can send messages here but not receive replies.
