Use SaaS Blocks 2.0 with Filter by Zapier

SaaS Blocks is a collection of +200 tools to augment your SaaS application - from messaging APIs and payments SDKs to analytics, dashboard, authentication providers.

Only allow a Zap to proceed when a certain condition is met. For example, if you're sending a text message when you receive a new email, you could use a Filter that only sends a text message when the email received is from a certain address.
