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 — Starts at 15/day, max 30/day. Steady-state for fully warmed-up mailboxes.
- Recovery — Starts at 5/day, max 30/day. Auto-applied when bounce or spam rates spike.
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): starts at 15/day and grows to 30/day max.
Note: If you are at the start of Maintenance mode and want to send more, you will need to wait for the system to ramp you up based on bounce and complaint metrics, OR add additional inboxes to distribute volume. 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
Daily Volume — Set your target warmup emails per day. The system ramps up to this target based on your ramp speed. Start low (5-10) for new mailboxes.
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.
