What our clients say

★★★★★

"Tried two other agencies before this. Neither one booked a single qualified call. Three weeks in with DemandSpring and we had meetings on the calendar. Night and day difference."

"I tried running cold email myself for months and couldn't make it work. Carter got me a closed deal in under two weeks. Wish I had just done this sooner."

Our Process

The System Behind Every
Booked Meeting

Four things have to go right for a cold email system to turn into qualified appointments on your agency's calendar. Most teams nail one or two. We build all four.

01

Cold Email Infrastructure

Most people set up domains, warm their mailboxes, and start sending. It works for about six weeks. Then a mailbox gets flagged, deliverability drops, and your pipeline goes dark for two weeks while you recover.

The problem is not the setup. It is that static infrastructure is fragile. We keep backup mailboxes warming at all times, and when anything underperforms we swap it instantly. Zero downtime, zero gaps.

Skip this and nothing else matters because nobody ever sees your emails.

02

List Building

The biggest mistake we see is sending the right message to the wrong people. Most teams filter by title and company size and call it targeting. That is demographics, not targeting.

We reverse-engineer your best customers to find the behavioral and situational signals that predict someone is ready to buy right now, then build your list around those signals across 100+ data sources. Every contact enriched, scored, and verified before a single email goes out.

Skip this and you burn through your entire market sending to people who were never going to respond.

Messaging

Most people approach messaging by guessing rather than letting the market decide. They write a few angles, pick their favorite, and send it. When it doesn't convert, they assume cold email doesn't work for their business. The real problem is they never found what actually resonates because they stopped testing before the data could tell them.

We launch 15 to 20 distinct campaign angles from day one. Every week the data tells us what is working and what isn't. We cut what underperforms and scale what converts. The market decides the message, not us.

Skip this and you run three angles, nothing hits, and you walk away from a channel that could have filled your calendar.

Appointment Setting

Everything upstream worked. Emails landed. The right people saw them. The messaging converted. Someone replied saying they are interested. Then your team took 18 hours to respond and the lead went cold.

A warm reply has a half-life of about four hours. We handle every reply within minutes, pre-qualify against your exact criteria, and book directly into your calendar. You show up and close.

Skip this and you paid for the entire machine and left the last valve closed.

Built by someone who's
actually sat in the chair

Most outbound agencies start with good intentions but little actual sales experience and end up learning on your dollar. Not DemandSpring.

With 5 years in the trenches, starting as an SDR booking meetings for marketing agencies and moving up to account executive, Carter knows what it takes to drive pipeline and close deals.

After generating over $2M in pipeline and testing every tool, strategy, and workflow along the way, he built the outbound system he wished he had. DemandSpring takes the guesswork out of cold email so you can scale with confidence.

FAQ

Common questions

We work exclusively with marketing agencies: SEO agencies, paid media agencies, social media agencies, web design studios, content agencies, and full-service shops. The common thread is a recurring retainer model, a defined offer, and a market large enough to run cold outbound at scale. If your average client is worth $5K+ and you have 50K+ prospects to go after, we can likely build a system that works.
Most agencies see their first qualified meetings within 3 to 5 weeks of launch. The first two weeks are infrastructure and warmup. This is the work most agencies skip, and it is exactly why their campaigns end up in spam. We do it properly so that when we send, we land. After that, you start seeing replies and booked calls come in consistently.
Very little. We need a 30-minute onboarding call to understand your offer, your ideal client, and what a qualified meeting looks like to you. If you have a current client list, that helps us build your lookalike audience faster. Beyond that, we handle everything: infrastructure, list building, copywriting, campaigns, replies, and calendar booking.
Cold email fails for three reasons: bad infrastructure (emails landing in spam), wrong list (targeting people who were never going to buy), or weak messaging (one angle, no testing). Most in-house attempts and cheap agencies miss at least two of these. We build all three from scratch: proper sending infrastructure with backup mailboxes, a list built around behavioral signals not just job titles, and 15 to 20 campaign angles tested from day one. One of them will convert. Then we scale it.
We have a few engagement models depending on your goals and volume. The best way to find out which fits is to book a strategy call and we will go through your situation and give you a straight answer on what it would cost and what you can expect. No pitch decks, no runaround.
