Fallback email and SMS explained

Messages to clients are sent through SMS or email. If the client’s contact information is missing or they have run out of credits, a backup method makes sure the message still gets delivered.

Here's how it works

For example, you use e-mail with SMS as fallback:

• When an email address is not available, but a cellphone number is available, an SMS will be sent
• When an email address is available, regardless if a cellphone number is available or not, an email will be sent

And vice versa for using SMS with email as fallback.

What happens when you run out of credits?

When using SMSs with email as fallback, emails will be sent if you run out of credits. If you are using emails with SMS as fallback, you will only need credits to send a fallback SMS if the email can't be sent.

Note: Fallback messages will not be sent if delivery fails, for whatever reason. For example, if an email address is incorrect or phone number does not exist.
