BandagBullet
cold email infra
BandagBullet is the cold email infrastructure purpose-built for SDR teams who measure reply rates, not vanity opens — engineered domains, mailboxes, warmup, and copy intelligence tuned to land in the primary inbox and book 3–5x more qualified meetings per rep per month.
Every layer of BandagBullet is built to compound deliverability. Buy, warm, send, and score from a single console — with CRM sync that closes the loop in under a second.
Inventory of aged, vetted domains plus registrar integrations to provision fresh ones. Automated rotation logic spreads volume across your portfolio to protect the health of every sender.
Our patent-pending warmup ramps new domains to 2.3x the deliverability of the Mailchimp / SendGrid baseline within 11 days — measured against independent seed lists, not our own network.
Dedicated Google Workspace or Microsoft 365 inboxes provisioned under your tenant — no shared IP reputation, no neighbor risk, full admin control.
The only platform scoring every recipient before the message leaves the queue. Block risky sends at the recipient level — our customers block an average of 11.4% of outbound mail per account.
Native 2-way sync with HubSpot, Salesforce, Pipedrive, and Apollo. Replies, opens, and replies-to-meeting write back without manual exports or Zaps in the middle.
Unsubscribe handling, suppression lists, physical-address footers, and consent capture tooling — included across every plan. Compliance tooling included, not sold as an add-on.
Four numbers our customers' RevOps leads screenshot and forward to finance. Independently sourced, audited quarterly.
Across the customer base in Q1 2026, processed through 41,000+ monitored sending domains.

BandagBullet was founded in 2019 by Lex Maruyama, the 4th employee at Outreach.io, alongside two former Salesloft engineers. Between the three of them, they had scaled one outbound platform from 80 logos to 4,200 — and watched, up close, every deliverability firefight that came with it.
The Series B closed in March 2024 — $42M led by Bessemer Venture Partners, with First Round and Zoom Ventures on the cap table. The team is now 87 full-time, split across Austin, Lisbon, and Bangalore, and the platform processes 2.1 billion email sends per quarter. None of that scale mattered, though, until the underlying infrastructure stopped being the bottleneck.
That's the whole bet. Domains, mailboxes, warmup, copy intelligence — engineered as one system, not four stitched-together vendors. Every layer answers the same question: does this email land in the primary inbox, and does it earn a reply?
