Email Sending Ramp, Opt In per Mailbox
Ramp a new mailbox gradually before higher-volume campaigns.
Bulk Email Boxer includes an optional campaign-send ramp on every paid plan, without a separate warmup subscription.
The problem
New email domains land in spam because they have no sender history. Third-party warmup tools cost $30-$50/mo extra.
The solution
Bulk Email Boxer includes an optional campaign-send ramp on every paid plan, without a separate warmup subscription.
Everything you need, included
- Explicit per-mailbox opt-in; off by default
- Gradual campaign-send cap: 5 → 30 emails/day over 15 days
- SPF and DMARC health shown per sender
- Works with Gmail, Outlook, Fastmail, Namecheap, and custom SMTP
- Ramp sends count as normal campaign sends
- Warmup Pool peer traffic requires a separate consent toggle
Simple, flat pricing
Starter: $40/mo · Growth: $90/mo · Scale: $350/mo
All plans include optional warmup controls, sequences, and reply handling. A/B testing is available on Growth and Scale. Seats are capped at 1, 3, or 10 by tier.
How it works
Connect your email account, import contacts, build a sequence, and launch. Warmup controls remain off until you opt in. Replies from connected inboxes appear in your unified inbox.
