Cold email your SDR team can count on to reach the inbox
Give every rep unlimited mailboxes on dedicated IPs, sequences that optimize themselves and one unified inbox with AI reply tagging. Pricing is per plan, not per seat, so hiring another SDR does not raise your software bill, and deliverability problems get caught before they cost the team a week of pipeline.
For SDR Teams

- Dedicated IPs
- Self-optimizing sequences
- AI reply tagging
More pipeline, fewer deliverability fires
No per-seat charges
The whole team works on one plan, so adding SDRs does not add to the bill.
Dedicated IPs
Your team sends from IPs used only by your organization.
Self-optimizing sequences
A/B variants with automatic volume shifting and stop-on-reply rules.
AI reply tagging
Replies sorted by intent so hot leads get answered first.
Step 1
Connect the team's mailboxes
Add Gmail, Outlook or IMAP/SMTP accounts with no per-seat charge. Warmup starts automatically and DNS checks confirm SPF, DKIM and DMARC are in place.
Step 2
Build sequences once
Multi-step sequences with branching, spintax and A/B variants on every step. Auto-optimization moves volume to the winner so reps are not babysitting tests.
Step 3
Work replies, not inboxes
Every reply lands in the unified inbox, tagged by intent. Interested leads surface first and can be pushed to your CRM with signed webhooks.
Who it’s for
Scaling outbound volume
Add mailboxes and spread sends with rotation instead of pushing more volume through each account. More mailboxes do not cost more on Sendbox.
Growing the team
Every rep works under one plan. Adding headcount does not add a per-seat charge.
Protecting pipeline
Per-mailbox reply and bounce rates, blacklist monitoring and placement tests catch a failing mailbox before it quietly drags down a rep's month.
Why SDR leaders care about the infrastructure
Your team's results should depend on your team
On shared sending infrastructure, another company's bad list can pull your placement down. Sendbox sends from dedicated IPs on isolated infrastructure, so the numbers your reps see reflect their own work.
No per-seat pricing
Many sales tools charge for every user, so the bill grows with every hire.
- Sendbox charges per plan.
- A five-person team and a fifteen-person team can sit on the same plan if their volume fits.
Less manual work for reps
Warmup, variant optimization, stop-on-reply and reply tagging run automatically.
- Reps spend their time answering interested leads, not maintaining campaigns.
It depends on volume. Plus covers 250,000 emails and 100,000 leads a month, Pro covers 500,000 emails with unlimited leads (under fair use), and larger teams can move to Agency or Power. Every plan includes dedicated IPs and no per-seat charges.
