Validation rules per workflow
SPIRITT validates addresses with Mailboxlayer and picks the checks each job needs: strict format, MX, SMTP, catch-all, role, free provider and disposable detection. Billing contacts get every check, newsletter signups a lighter pass, and results flow straight into your systems.

Questions
Mailboxlayer, with SPIRITT.
01Which checks can Mailboxlayer run?+
Strict format validation, MX records, SMTP, catch-all detection, role-based detection, free-provider detection and disposable detection. Each can be switched on or off per check.
02What is a catch-all domain?+
A domain that accepts mail for any address, so a pass does not prove the inbox exists. SPIRITT marks these contacts so your team confirms them another way.
03Why choose different checks per workflow?+
Billing and contract contacts need every check, while a newsletter signup may only need format and disposable checks. SPIRITT applies the policy you define to each source.
04How does free-provider detection help?+
It separates personal mailbox providers from company domains, so SPIRITT routes B2B leads to sales and individuals to the right nurture path.
05Can validation run automatically?+
Yes. SPIRITT checks new customers, leads, invites or subscribers on your schedule and writes results back to the apps they came from.
06What do I need to connect?+
Your Mailboxlayer API access key, plus the CRM, billing or email platform where contacts live.
