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.
