Warmup Settings & Ramp Modes
Each mailbox has its own warmup configuration. Go to Warmup and click on a mailbox to configure:
Ramp Speed — Controls how quickly daily volume increases:
- Conservative — Slowest ramp (0.08 growth rate). Safest for brand-new domains.
- Normal — Balanced ramp (0.12 growth rate). Good default for most mailboxes.
- Aggressive — Fastest ramp (0.20 growth rate). Only for established domains with existing reputation.
Strategy Modes — The system uses intelligent strategies that auto-evolve based on your mailbox's age and performance:
- New Domain — Starts at 1 email/day, max 40/day. For brand-new domains with zero history.
- New Mailbox — Starts at 3/day, max 60/day. For new mailboxes on established domains.
- Dormant — Starts at 3/day, max 40/day. Auto-applied when a mailbox is idle for 14+ days.
- Maintenance — steady-state for a fully warmed-up mailbox. While your emails keep landing in the inbox, it keeps sending at the target you set instead of a fixed low number.
- Recovery — applied automatically when inbox placement dips. It eases volume right down while your reputation settles, then lifts it back toward your target on its own once placement recovers.
New Domain Ramp Table (day-by-day)
Here is what the typical New Domain ramp looks like at Normal speed, assuming healthy bounce and complaint metrics throughout:
Day 1: 1 email/day
Day 2-3: 1-2 emails/day
Day 4-5: 2-3 emails/day
Day 6-7: 3-4 emails/day
Day 8-9: 5-6 emails/day
Day 10-11: 7-8 emails/day
Day 12-13: 9-10 emails/day
Day 14: ~11-12 emails/day
Day 21: ~18 emails/day (auto-graduates to New Mailbox mode)
Day 30: ~30 emails/day
Day 45+: 40 emails/day (New Domain cap)
Maintenance mode (after graduation): keeps climbing toward the target you set, as long as your mail lands in the inbox.
Note: Maintenance still ramps gradually — as your mail keeps landing in the inbox, volume rises toward your target. To send more overall, raise your target or add more inboxes. The ramp is intentionally gradual to protect your sender reputation — pushing harder increases the risk of landing in spam.
Automatic Strategy Transitions (A.H.D.E. System):
- New Domain auto-promotes to New Mailbox after 30 days
- New Mailbox auto-transitions to Maintenance after 21 days of active sending
- If bounce rate exceeds 10% or spam rate exceeds 5%, the system auto-switches to Recovery mode
- After successful recovery, the system returns to your previous mode
- If you manually set a strategy, auto-evolution is paused for 30 days — except a mailbox that was moved into Recovery automatically will still return toward your target on its own once placement recovers.
Daily Volume — Set your target warmup emails per day, up to a maximum of 120. The system ramps up to this target based on your ramp speed. Start low (5-10) for new mailboxes. The number you see on your warmup dashboard is the most this mailbox will send today.
Time Window — Set the hours and timezone during which warmup emails are sent (default: 24 hours, all day).
Health Score — Monitor your score (0-100): Excellent (80+, green), Good (60-79, blue), Fair (40-59, yellow), Critical (below 40, red). Keep it above 70 before starting campaigns.
