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.
