Questions we get
every week.

• What if the person I'm messaging doesn't have iMessage?

  It still reaches them, automatically. The message falls back to RCS, or to SMS where RCS is not available, from the same number and with nothing for you to configure or switch on. So an Android customer is not a customer you cannot answer, and you do not keep a second number for them. It arrives as a green bubble with whatever that channel supports, which is why a read receipt or a typing indicator may not be there.

• How do I know whether a message went blue or green?

  Every message records the service that carried it, so a thread tells you which channel each message actually used rather than leaving you to guess from a colour. You can also ask before sending: a lookup answers reachable, undeliverable, or unknown, from your own traffic rather than from Apple. Unknown means nobody has tried this handle yet, which is what every genuinely new customer looks like — it is a reason to send, not a reason to avoid it.

• Do you support voice memos and attachments?

  Yes. Send images, videos, PDFs, and audio, and receive attachments in the shared conversation. A single audio attachment sent without text or a quoted reply uses the native voice-note path by default; an integration can set native_voice_note to false to send it as a regular attachment. If native delivery is unavailable before sending, Miss Blue automatically sends a regular playable audio attachment.

• Can I call from these numbers?

  Yes. Start FaceTime Audio for a reachable Apple contact or a regular Phone call for a dialable phone number, directly from the conversation. Browser audio is the default for outbound phone calls once the line is ready for calling. Incoming phone calls can forward to a destination you choose separately for each number. The project's Calls page keeps both call types, the caller, outcome, ring time, and talk time together.

• Can I bring my own phone number?

  Yes, you can request a transfer when setting up a paid dedicated number. Choose your current carrier and enter the number, account number, transfer PIN if issued, and billing ZIP. You can also give forwarding instructions and notes. Staff review and complete the transfer; it typically takes 1–2 weeks. Keep the existing SIM active until the transfer completes.

• Can I do message blasts?

  No, and this is enforced rather than discouraged. A line is capped at fifteen messages a minute, and anything past that is spaced four seconds apart instead of refused — so an ordinary busy conversation never notices, and a pasted list of five hundred contacts hits it immediately. Blasting is what gets numbers flagged, and a flagged number is one nobody's messages arrive from.

• Is it really unlimited texting?

  Conversations are not what is limited: replies never count against new people. New people per line per day are: 50 by default, seven an hour, and a line sends at most 150 messages a day in all. That is not a billing lever — it is what keeps a number looking like a business rather than a broadcaster. If you need more reach, more lines is the answer.

• Is there an API?

  Yes, with a command line and an MCP server for supported messaging workflows. Send, read threads, look a handle up, react, unsend, manage contacts, and register webhooks. API keys belong to a project; signed-in account actions such as billing and regular phone calling are separate. The API reference lists the supported endpoints and the CLI guide lists its available tools.

• Who on my team can see which conversations?

  Whoever you put in the project. Numbers live in projects and people are added to projects, so a receptionist and a recalls clerk can share a workspace without sharing an inbox. Your own admins do this — you do not ask us every time somebody joins or changes desk.
