Frequently Asked Questions

Multi combines an asynchronous, queue-backed Laravel application layer with an enterprise Postfix transfer agent, automated 2048-bit DKIM signing, real DNS verification, and full HTTP webhook telemetry.

Yes. Both interfaces share the same unified suppression list, domain verification rules, quotas, and real-time event logs.

When you add a domain, Multi generates a unique 2048-bit RSA DKIM key and provides SPF, DKIM, and DMARC TXT record values. Clicking "Verify Domain" performs real DNS queries against your domain's nameservers.

You can toggle tracking globally in your dashboard Settings or override it per request in the API payload via open_tracking: false.
