Smartlead export planning

Size inbox capacity before a Smartlead export job blocks rows.

Estimate how many inboxes and domains should be ready before pushing SMTP accounts into Smartlead campaigns.

Calculator

Model the send load.

GTM exports should partition ready and blocked inboxes with redacted reasons. This page models capacity; it does not guarantee Smartlead acceptance or inbox placement.

Per-IP utilization should stay below 80 percent before adding traffic. Scale horizontally with more IPs or domains before raising inbox caps.

Readiness notes

  • Treat this as a planning estimate, not a quote or deliverability guarantee.
  • Readiness gates, seed-placement evidence, and fresh SMTP/IMAP smoke tests still decide exportability.
  • GTM-managed shared SMTP capacity; IP count is a planning signal, not a line item.

Common questions

Does this connect to Smartlead directly?

No. This public page is a planning calculator. Authenticated GTM workflows handle provider credentials and export jobs without exposing secrets.

What should be checked before exporting to Smartlead?

Check SMTP readiness, IMAP readiness, DNS authentication, launch gates, suppression policy, and seed-placement evidence before prospect traffic starts.
