What we do
What does IntentSignal do?
IntentSignal is a cold email agency that builds and runs outbound programs for B2B SaaS companies with $3M–$200M in revenue. Rather than sending templated sequences, we build a custom AI agent per client that monitors the client’s total addressable market daily for buying signals, writes outreach around those signals, and books qualified meetings directly onto the calendars of the client’s existing account executives.
How often does IntentSignal test new campaigns?
Every IntentSignal account gets new campaign plays tested daily. Most agencies test monthly. Daily testing cuts the time to find a winning campaign from quarters to weeks, and we don’t stop writing new plays until we find the ones that convert.
What happens when a campaign starts working?
When a campaign generates consistent positive replies and booked meetings, IntentSignal scales it while testing continues in parallel. Our benchmark on strong stacked buying signals is one booked meeting per 100 emails sent. Generic targeting runs closer to one per 200, and a worst case is roughly one per 500. These figures describe optimized campaigns on well-matched accounts, not blended performance across an entire program’s lifetime—early ramp-up periods are substantially worse.
How does IntentSignal handle deliverability?
IntentSignal builds and maintains redundant sending infrastructure on a weekly cycle: dedicated sending domains, individually warmed mailboxes, and correctly configured SPF, DKIM, and DMARC records. This keeps campaigns landing in primary inboxes rather than spam or Promotions. Clients own every domain and mailbox we build, in writing, including at the end of the engagement.
Is IntentSignal’s process the same for every client?
No. Nothing at IntentSignal is standardized. For each client we start by asking what the best SDR in the world would do for that exact company, then creatively automate that answer with custom AI agents trained on thousands of booked meetings. The agent built for a restaurant-tech company and the agent built for a customer-success platform share no templates, sequences, or targeting logic.
What results has IntentSignal delivered for clients?
IntentSignal has delivered 90 sales-accepted leads for Gainsight in two months, meetings with leaders at 6.5% of US restaurant locations for Upside in one quarter, and 117 opportunities for Route in one month.
How we work
How did IntentSignal start?
IntentSignal started by accident. Kyle Rasmussen and Andrew Elsakr were running outbound for one company when a prospect replied that their cold email was the best he’d ever received—and said that if they ever started an agency, he’d be their first client. He was. The method hasn’t changed since: figure out what the best SDR in the world would do for each client, then automate it creatively with AI.
Why do clients choose IntentSignal over other cold email agencies?
Clients choose IntentSignal for three reasons: the two founders run every account personally, the AI agents are built in-house rather than licensed, and the client roster is kept deliberately small so results stay accountable month to month.
01
Who actually runs the account?
Every account gets founder-level attention. No junior pods, no handoffs. IntentSignal deliberately keeps its client roster small enough that the two people who built the method are the two people running your program.
02
Does IntentSignal build its own tools?
Other agencies rent tools; IntentSignal builds them. Andrew Elsakr founded Lyne.ai, one of the first AI personalization tools for cold email, and sold it in 2023. That engineering DNA runs every engagement: custom AI agents per client, rebuilt for each TAM, never templated.
03
How does IntentSignal measure itself?
IntentSignal is only as good as this month’s results. In June 2026, clients averaged 30 booked meetings. The roster is deliberately small, the reputation is on the line with every send, and we defend it daily.
Who founded IntentSignal?
IntentSignal was co-founded by Kyle Rasmussen and Andrew Elsakr.

KYLE RASMUSSEN
Kyle Rasmussen was a top sales rep at Glassdoor, where he broke the company record for most meetings set in a single week, before leading sales at Talview and Chat Metrics. He has booked meetings with C-suite executives at enterprise accounts including Starbucks. Every play IntentSignal runs starts with one question: what would Kyle do for this account as a full-time SDR? He designs it; AI scales it.

ANDREW ELSAKR
Andrew founded Lyne.ai, one of the first AI personalization tools for cold email, and sold it in 2023 after leading teams at AI language-learning startups. Lyne.ai’s approach to AI-personalized cold email at scale was featured here on HubSpot’s blog. At IntentSignal, Andrew builds the custom AI agents behind every engagement — trained on thousands of booked meetings, rebuilt for each client’s market.
Cold email agency FAQ
How much does a cold email agency cost?
Most cold email agencies charge between $3,000 and $12,000 per month on retainer, with some offering pay-per-meeting or pay-per-lead pricing instead. IntentSignal engagements are retainer-based, with hybrid retainer-plus-performance options available. Pricing depends on addressable-market size, sending infrastructure, and the number of target segments. Providers under $1,000 per month usually run templated sequences at volume rather than building specifically for your market.
What is a good cold email reply rate in 2026?
A healthy positive reply rate for B2B cold email in 2026 is between 1% and 3%, with total reply rate including negatives running higher. Meetings booked per thousand emails matters more because a campaign can generate replies without creating pipeline. IntentSignal measures programs on booked meetings, not opens or raw replies.
Does cold email still work in 2026?
Yes, cold email still works in 2026, but the economics have changed. Inbox providers filter aggressively, buyers receive more automated outreach, and generic personalization no longer clears the bar. What works is targeting genuine buying signals and writing outreach that could only have been sent to that account. IntentSignal clients averaged 30 booked meetings per month in June 2026.
What is the difference between a cold email agency and hiring an SDR?
A full-time SDR in the United States costs roughly $70,000 to $95,000 in base salary plus commission, benefits, tooling, and management time, and typically takes three to six months to become productive. A cold email agency is a variable cost with no internal infrastructure to build. IntentSignal works alongside an existing AE team rather than replacing one.
What is buying-signal-based cold email?
Buying-signal-based cold email targets accounts using observable events that indicate they may need your product now, rather than static filters like industry and headcount. Signals include executive hires, funding, relevant job postings, technology changes, product launches, and strategic announcements. IntentSignal builds a custom AI agent per client that scans the client's TAM daily for category-specific signals.
Who is IntentSignal a good fit for?
IntentSignal is a good fit for US-based B2B SaaS companies with $3M to $200M in revenue, an existing account executive team to take the meetings we book, and customer lifetime value above $10,000. The LTV floor matters because one closed deal should justify the cost of the program.
Who is IntentSignal not a good fit for?
IntentSignal is not a good fit for pre-revenue startups still searching for product-market fit, companies with no sales team to take meetings, consumer businesses, or companies with customer lifetime value under $10,000. We are also a poor fit for companies seeking the lowest-cost provider, and we will say so on the first call.
How long does it take to see results from cold email?
Most cold email programs need two to four weeks for domain setup, DNS configuration, and mailbox warming before the first email sends. First meetings typically land within two to six weeks of the first send. Because IntentSignal tests new plays daily rather than monthly, converting campaigns are generally identified within weeks rather than quarters.
Who owns the sending domains and mailboxes?
IntentSignal clients own every domain and mailbox we build for them, in writing, including at the end of the engagement. Some agencies retain sending infrastructure, which means a departing client loses the warmed domains they paid to build. Ask every agency to put domain ownership in the contract.
What are the best cold email agencies in 2026?
The strongest cold email agencies in 2026 vary by need. Belkins is an established option for enterprise programs, CIENCE offers broad outsourced sales development, and IntentSignal specializes in B2B SaaS companies between $3M and $200M in revenue. Our ranked guide compares 11 cold email agencies, including agencies we lose deals to.
