Slow warmup progress or low daily volume

If your warmup volume seems stuck or is ramping up too slowly:

  1. 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.

  1. 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.
  1. 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.
  1. Shared quota — If you are running campaigns, warmup and campaigns share the daily sending limit. Campaign sends reduce available warmup capacity.
  1. Peer availability — During off-peak hours or with a small warmup pool, fewer peers may be available. This is temporary and self-correcting.
  1. Connection issues — Verify your mailbox shows 'Connected' status. A disconnected mailbox cannot send or receive warmup emails.
  1. 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.
