Cold email that SDR teams can trust to land in primary
Equip your SDR team with dedicated IPs, sequences that optimize themselves, a built-in dialer, and one unified inbox. No shared infrastructure, no gambling on deliverability, every rep sends from IPs that answer to your team alone.
For SDR Teams
Solutions
Connect your team's mailboxes
Add as many Gmail, Outlook, or IMAP accounts as your team needs, with no per-seat charges attached. Warmup kicks off automatically in the background while DNS health checks confirm your SPF, DKIM, and DMARC records are in order.
- No per-seat charges
- Dedicated IPs per team
- Built-in dialer
- AI reply tagging
More pipeline, fewer deliverability fires to put out
No per-seat charges
Your whole team runs on a single plan, so adding SDRs doesn't add to your bill.
Dedicated IPs per team
Your team sends from IPs that belong to your organization alone, with no shared pool touching other companies.
Built-in dialer
Call leads without ever leaving the platform. Call recording, health scores, and analytics all come standard.
AI reply tagging
Replies get sorted by intent automatically, routing hot leads to the right rep without anyone doing it by hand.
Step 1
Connect your team's mailboxes
Add as many Gmail, Outlook, or IMAP accounts as your team needs, with no per-seat charges attached. Warmup kicks off automatically in the background while DNS health checks confirm your SPF, DKIM, and DMARC records are in order.
Step 2
Build sequences with A/B testing
Build multi-step sequences with conditional logic, spintax, and A/B variants at every step. Smart optimization automatically pauses whatever isn't working, so your team's attention stays on what is.
Step 3
Manage replies and call leads
Every reply funnels into one unified inbox. AI tagging sorts responses by intent automatically (interested, not interested, out of office, and so on), and the built-in dialer lets you call warm leads without leaving the platform.
Who it’s for
Scaling outbound volume
Teams pushing 50K-500K emails a month need infrastructure built to handle that load. Dedicated IPs paired with sender rotation across unlimited mailboxes let you scale up without torching your domains along the way.
Multi-rep team management
Because there's no per-seat pricing, bringing on another SDR adds nothing to your bill on Sendbox. Compare that to Lemlist at $109/user/mo or Apollo at $79/user/mo, where every new hire is a new line item. Your whole team shares a single plan instead.
Multichannel with email + calling
Run your email sequences and place calls through the built-in dialer without switching platforms. Call recordings and health scores keep track of how each rep is actually performing.
What pulls SDR teams over to Sendbox
Infrastructure that scales with your SDR team, not your headcount bill
Most cold email tools charge per seat and dump every rep onto shared IPs, so scaling from 3 SDRs to 10 multiplies your bill right along with your team. Sendbox charges per plan, not per seat, and every rep still gets their own dedicated IP.
- Beats Lemlist
- Beats Apollo
- Beats Reply.io
No per-seat pricing
Sendbox bills per plan, not per user, so a five-person SDR team costs the same as a solo one.
- That same five-person team on Lemlist's Multichannel Expert runs $545/mo (at $109/user), and on Apollo Professional it's $395/mo (at $79/user).
- The gap only grows as your headcount does.
Built-in dialer for warm follow-ups
The moment a lead replies with interest, your SDR can call them straight from Sendbox, no jumping to a separate dialer tool.
- Call recording, health scores, and analytics all come built in.
- Most competitors either skip a dialer entirely (Instantly, Woodpecker) or charge extra to unlock one.
The Plus plan covers your entire team, 250,000 emails, 100,000 leads, and dedicated IPs, with no per-seat charges added on. For comparison, Lemlist at $109/user/mo runs $545/mo for a team of 5 SDRs.
