Presets
- Conservative — slowest ramp, lowest risk; the right choice for a new domain
- Balanced — the sensible default for most mailboxes
- Aggressive — fastest ramp; only for an established domain with clean history
What the settings control
- Starting and target daily warmup volume
- How quickly volume increases
- Which days and hours warmup runs
- Safety thresholds that pause the mailbox when bounce or complaint rates rise
Important notes
- Auto-pause is protection, not an error. A mailbox paused by a safety threshold is telling you something about your list or domain.
- Changing to Aggressive mid-ramp does not shortcut reputation; it just increases the odds of tripping a threshold.
