Why Bulk Email Boxer exists
Most cold email tools fall into one of two camps:
- SaaS with shared sending IPs, fast to set up, but your domain reputation rides on whatever everyone else on that IP is doing. One neighbour spams, your inbox rate cliff-drops.
- Sequencers without warmup, they queue mail through your own mailbox, but skip the daily volume ramp that builds sender reputation on a fresh domain. You get blacklisted in week two.
We built Bulk Email Boxer for the middle ground: send through your own connected mailboxes, with automatic warmup and send-window scheduling that respects each recipient's timezone.
What's in the box
- Real mailbox sending. Connect your own mailboxes, any provider with SMTP/IMAP. We never touch your DNS, your reputation, your domain.
- Warmup that mirrors human patterns. Daily volume ramps with reply, archive, and star simulation against a private peer pool.
- Timezone-optimized delivery. Each lead's email lands at 9am their local time, not yours.
- Deliverability monitoring. SPF / DKIM / DMARC checks per sender, with red-amber-green scoring and one-click fixes.
- Sequencing with branching. A/B test subject lines and bodies, then branch on opened / replied / clicked.
What we don't do
- Send through our IPs (we don't have any, your mailbox is the relay).
- Buy lead lists. Bring your own.
- Hide bounces. If a campaign is hurting your reputation, we tell you.
