Why Teams Switch to Sendqube
Most cold email platforms focus on one thing — sending more emails. We think that's the wrong problem. Sales teams don't close deals because they sent 100,000 emails. They close deals because they start conversations, build relationships, and respond at the right moment.
Most cold email tools help you send faster. Sendqube helps you send safely.
Fast sending from an unmonitored domain just gets you flagged faster. Sendqube warms up new mailboxes, rotates sends across inboxes, and watches for bounce and blacklist issues — so the volume you're building doesn't cost you your sender reputation.

To make cold outreach feel like real communication — not mass marketing. Whether you're a solo founder, sales team, marketing agency, recruiter, or enterprise, Sendqube helps you manage every conversation from one intelligent workspace.
Why we started
Most cold email platforms force you into their ecosystem — their inboxes, their infrastructure, their limitations, their pricing. When your business grows, switching becomes painful. We wanted something different: a platform that works with your existing email providers, not against them. Whether you use Gmail, Microsoft 365, Outlook, or your own SMTP server, Sendqube brings everything together in one place.
What makes Sendqube different
Most tools help you send campaigns. Sendqube helps you manage conversations.
Built for conversations, not campaigns.
Every cold email platform promises more inboxes, more warmup, more automation, more sending. But after someone replies, most platforms become just another inbox. Sendqube was designed from the ground up to manage the entire sales conversation.
One platform. Every email provider.
Most tools support Gmail well. Some support Outlook. Very few support custom SMTP properly. Sendqube supports all of them — no vendor lock-in.
Native, OAuth-connected support for Gmail and Microsoft 365 — plus any SMTP-compatible provider, including Zoho, Amazon SES, Mailgun, and Brevo.
One inbox for every conversation.
No matter where the email originated, every reply appears inside one conversation. No switching tabs, no logging into different providers, no losing context.
Website intelligence
Know when prospects are interested. Track email opens, link clicks, website visits, and pages viewed — including returning visitors — so you can focus on the prospects who are actually engaging.
Built for agencies
Manage multiple clients with separate workspaces, separate domains, and separate inboxes — all from one dashboard.
Enterprise ready
- Role-based access (owner, admin, member)
- Unlimited contacts on Enterprise
- Every provider — Gmail, Microsoft 365, and SMTP — in one workspace
- High-volume sending with per-mailbox pacing
- Signed webhooks into your own systems
No vendor lock-in.
Your email accounts stay yours. Your SMTP servers stay yours. Your Microsoft accounts stay yours. Your Gmail stays yours. You own your infrastructure — not us.
