SendtoWin Launches SendTech to Get Cold Emails Into the Inbox

DELRAY BEACH, FL, September 28, 2026 (EZ Newswire) — SendtoWin, the B2B outbound company ranked No. 254 on the 2026 Inc. 5000, today announced the public launch of SendTech, a deliverability-first email infrastructure platform built for sales teams, software companies, and AI agents.

SendTech gives companies one place to purchase or connect domains and mailboxes, automatically warm sending accounts, monitor inbox health, manage deliverability, and connect that infrastructure to the outbound sequencer or sales platform of their choice.

The launch turns years of infrastructure and deliverability experience from SendtoWin’s managed outbound business into a standalone software platform. SendtoWin has helped more than 500 companies generate over $2.6 billion in pipeline and $380 million in revenue through B2B outbound campaigns.

“We built SendTech because deliverability has become one of the most important parts of outbound,” said Martin Aguinis, co-founder of SendtoWin. “Companies can have incredible targeting, great copy, and increasingly powerful AI agents, but none of that matters if the email never reaches the inbox. We wanted to take everything we have learned managing outbound infrastructure at scale and make it available as a product that any team or developer can use.”

Built Around Deliverability

The growth of AI-powered sales tools has made it easier than ever to generate messaging and automate outbound workflows. At the same time, email providers have become increasingly sophisticated in how they evaluate sender reputation, domain health, engagement patterns, and sending behavior.

SendTech was built to manage the infrastructure layer underneath those outbound systems.

Companies can purchase new domains and mailboxes directly through SendTech or connect existing Google Workspace and Microsoft 365 accounts. Mailboxes can then be placed into automated warmup pools designed to establish and maintain sender reputation.

SendTech continuously monitors infrastructure health rather than treating warmup as a one-time process. Its automated spam rescue system checks accounts every two hours for warmup emails that have landed in spam and moves qualifying messages back to the inbox. The platform also monitors SPF, DKIM, DMARC, blacklists, bounces, and mailbox health.

Customers can then connect those mailboxes to the sequencer or outbound platform they already use.

“Most sales technology focuses on who to contact, what to say, and how many emails to send,” Aguinis said. “SendTech focuses on the infrastructure underneath all of that: the domains, mailboxes, reputation, warmup, and health that determine whether those messages actually reach the inbox.”

Infrastructure for Sales Teams, Software Platforms, and AI Agents

SendTech is also designed for software companies and the growing category of AI agents performing sales and go-to-market tasks.

Through the SendTech API, developers can provision domains and mailboxes, manage warmup, and access inbox health data programmatically. This allows companies to incorporate email infrastructure directly into their own software products and automated workflows.

An MCP server is also planned, giving compatible AI agents another way to interact directly with SendTech’s infrastructure.

For example, an AI agent could eventually provision outbound domains, create mailboxes, warm those accounts, check their health, and prepare infrastructure for campaigns using SendTech.

“AI is rapidly changing who or what is actually operating the sales stack,” said Samuel Shandler, co-founder of SendtoWin. “As agents become capable of doing more outbound work autonomously, they still need reliable email infrastructure underneath them. Our goal is for SendTech to become that infrastructure layer.”

From Internal Infrastructure to Self-Service Platform

SendTech grew out of SendtoWin’s experience managing end-to-end outbound programs across dozens of B2B industries.

SendtoWin works with hundreds of companies ranging from high-growth startups to globally recognized brands 

The company has generated more than $2.6 billion in pipeline and $380 million in revenue for clients through outbound programs spanning targeting, copywriting, email and LinkedIn outreach, sequencing, and deliverability infrastructure.

That experience increasingly pointed to email infrastructure as a distinct problem companies needed to solve regardless of which sales engagement platform they used.

SendTech was created to make that infrastructure available independently.

“SendtoWin will continue to run fully managed outbound programs for companies that want us to handle everything for them,” Aguinis said. “SendTech opens up the technology underneath that work to a much broader market. Whether you’re a sales team managing outbound yourself, a software platform serving thousands of users, or an engineer building AI sales agents, you can now access that infrastructure directly.”

At public launch, SendTech reports more than 550 organizations active on the platform, with infrastructure operating across the United States, Canada, and Europe.
