Founder-Led Cold Email Agency for B2B Companies

At many agencies, a senior person sells the work, then hands it off to a junior rep who follows a playbook. That matters because cold email strategy changes fast. The person writing your emails needs to understand your offer well enough to write about it like an insider. At Sales Automation Systems (SAS), Founder Taylor Haren stays hands-on with every account, from campaign strategy through execution.

Most agencies report reply rates, so they write for replies: an AI-written first line, “worth a quick chat?” at the end, and a follow-up every few days. Replies are easy to count, but plenty of them never turn into a meeting. Ask what number the agency is paid to move. Our emails link to a page on your site instead of asking for a reply, and we track who goes on to sign up or book a meeting. Meetings are the number we chase.

Daily sends from warmed-up inboxes are what spam filters are built to catch, and they wear out your market fast. We send one human-written email a week. Before it goes out, your list is verified and cleaned, and our sending partner picks the send window from its own data.

Per-lead or per-meeting pricing sounds low-risk, but it can push the agency to chase volume over quality. You can end up with a calendar full of meetings that don’t convert because the agency optimized for quantity, not fit.

Revenue share ties the agency’s pay to your closed deals, so you agree on attribution and give the agency visibility into your sales numbers.

A flat retainer means you pay a set fee for a set sending volume, so you can judge the channel on its results. We use a flat quarterly retainer. You prove the channel first, then expand with more capacity or custom terms once you’ve got the data. After that, we can also add performance-based terms after a few months on our retainer, as we did with Fyxer.

Building in-house requires buying the tools, setting up multiple sending domains, sourcing leads, writing copy, and managing deliverability every day. Single Grain, a digital marketing agency, ran into bouncing emails and flagged domains. Its CEO, Eric Siu, said the team spent more time troubleshooting than reaching prospects.

Hiring an SDR means paying a salary on top of the same tools, data, and domain infrastructure. That person still needs to learn your market, build the sending stack, and figure out what messaging lands. Until they’re up to speed, your pipeline waits.

Working with us gets you live in as little as one week. You’re working with a team that’s already built the infrastructure and run the playbook for 100+ companies. The tradeoff is you’ll need a sales team on your end to take the meetings and close.
