Check if a number uses iMessage

Find out if a phone number or email supports iMessage | iMessage For Business

The Sendblue API allows you to call an endpoint to figure out if a number supports iMessage. This is pretty useful to determine:

  • Whether a certain phone number is an iPhone or not.
  • If a number is real before sending a message.
  • Whether to use Sendblue or another provider to send a message.

Use the /api/evaluate-service endpoint to check if a number uses iMessage.

Lookups have their own separate rate limits and do not count against your message sending limits.
