Slow warmup progress or low daily volume
If your warmup volume seems stuck or is ramping up too slowly:
- Normal behavior — New domains start at 1-3 emails/day with Conservative ramp. This is intentional to protect your domain. The system increases volume gradually over 2-4 weeks.
2) Check your ramp speed — Go to Warmup, click your mailbox, and check the ramp speed setting:
• Conservative: 0.08 growth rate (slowest, safest for new domains)
• Normal: 0.12 growth rate
• Aggressive: 0.20 growth rate (only for established domains)
If you are on Conservative and your domain has some history, consider switching to Normal.
- Check your daily volume cap — Your configured max daily warmup emails may be limiting volume. The system ramps toward this target but won't exceed it.
- Recovery mode — If your mailbox auto-switched to Recovery mode due to high bounce or spam rates, volume is intentionally reduced. Check your warmup strategy in mailbox settings. Let Recovery complete before expecting higher volume.
- Shared quota — If you are running campaigns, warmup and campaigns share the daily sending limit. Campaign sends reduce available warmup capacity.
- Peer availability — During off-peak hours or with a small warmup pool, fewer peers may be available. This is temporary and self-correcting.
- Connection issues — Verify your mailbox shows 'Connected' status. A disconnected mailbox cannot send or receive warmup emails.
- Plan limits — Check that your subscription is active. Free or expired plans may have reduced warmup capacity.
If volume has been stuck at the same level for more than 7 days with no obvious cause, disconnect and reconnect your mailbox, then re-enable warmup.
