Understanding Sending Capacity
Capacity scoring explained.
What capacity scoring measures
MailFleet estimates how aggressively you can send on a profile without exceeding provider quotas or risking elevated bounces.
Factors
Provider quotas, account age, bounce rates, complaint rates, and campaign size affect safe send rates.
- Daily and hourly provider limits
- Recent bounce percentage
- List size vs warm-up history
- Authentication status
How to use scores
Treat capacity scores as planning guidance, not guarantees. Increase volume gradually on permission-based lists after clean test batches.
Key takeaways
- Daily and hourly provider limits
- Recent bounce percentage
- List size vs warm-up history
- Authentication status
