When to use this.

The "Verify Catch-All Email" action is designed to determine whether a specified domain email address employs catch-all routing, which allows it to accept emails sent to any address at that domain. This action requires a single input parameter: the email address (text) that needs verification. Upon execution, it returns a status (text) indicating whether the email address is configured as a catch-all. This functionality is particularly useful for businesses and marketers seeking to validate email addresses for lead generation, ensuring effective communication by identifying domains that accept all emails. Categorized under enrichment, this action enhances data quality and integrity, making it an essential tool for email verification processes.

FAQ.

  • Is this real-time?

    Yes. Synchronous actions return in ~1–4 s. Long-running work uses async polling (see status 504 → switch to async).

  • Do I get charged on failure?

    No. Verified failures cost zero credits. Provider miss / 5xx / timeout cascade to the next provider in the waterfall when applicable.

  • Does it work with Claude / Cursor via MCP?

    Yes. Add the texau MCP server to your client config, then call `texau__better enrich-...` directly.

  • What CRMs can I push results to?

    HubSpot, Salesforce, Pipedrive, Zoho, and GoHighLevel are bidirectional. Smartlead, Instantly, Lemlist, HeyReach, Apollo Sequences, and Reply.io for outbound.
