Plan the batch before export
Start with capacity planning for the expected prospect volume, touches, and send days. If the plan needs more domains or inboxes, fix that before wiring accounts into Instantly. Capacity calculators are planning aids, not deliverability guarantees.
- Estimate inbox count with conservative per-inbox daily caps.
- Estimate domain count with conservative per-domain daily caps.
- Use DNS checks before treating the capacity plan as operational inventory.
Require readiness before provider setup
A mailbox row should not be exported to Instantly if it cannot prove the basics. The readiness model should catch missing managed MTA assignment, SMTP metadata, IMAP metadata, encrypted credential metadata, and recent operational test signals.
Keep remediation safe and specific
When a row is blocked, the operator needs a precise next action without secrets. Use redacted reasons such as missing SMTP host, missing IMAP username, missing encrypted credential, failed smoke test, or inactive inbox status instead of raw provider or credential data.
