[Kenny Damian](https://www.linkedin.com/in/kenny-damian-90aba221a/), Head of GTM 12 min read Updated Nov 6, 2026 Frontal Growth Engine X **Category** Go-to-market partner **Category** Cold email agency **Services** Outbound, ABM, paid media, content, RevOps **Services** Cold email, list building, deliverability **Best for** B2B tech teams that need more than one channel working the same accounts **Best for** B2B companies with 100,000+ contacts in their market Quick answer Frontal is a go-to-market partner that runs [signal-based outbound](https://frontal.so/services/gtm-engineering), [account-based marketing](https://frontal.so/services/account-based-marketing), [paid media](https://frontal.so/services/paid-media), [content](https://frontal.so/services/content-engineering) engineering and [RevOps](https://frontal.so/services/revops) for B2B tech companies, with every service working the same target accounts inside the client’s own CRM and Clay. Growth Engine X focuses on one service, high-volume cold email, for B2B companies with large markets and their own team to follow up on responses, which means the rest of your pipeline work goes to other partners. Methodology ## How We Weighed Frontal Against Growth Engine X We looked at both companies the way a B2B tech team would once pipeline becomes the priority, starting with the work that needs covering. That meant checking which go-to-market services each one runs, who each is built for, what happens once a prospect replies and which number ends up in your report. Growth Engine X’s details come from its own site and its listing in Clay’s partner directory, both checked in October 2026. Ours come from Frontal’s service pages and published case studies, and anything a company doesn’t make public stays out. Yes, Frontal wrote this, so you know where our loyalties sit. Clay’s directory lists both of us at Elite Studio, its top partner tier, so the Clay badge won’t be what separates us. \[ At a glance \] ## Frontal and Growth Engine X Side by Side | Criteria | Frontal | Growth Engine X | | --- | --- | --- | | Category | Go-to-market partner that works as an extension of your team and runs the campaigns, the replies and the reporting. | Cold email agency that builds and sends high-volume campaigns for B2B companies. | | Built For | B2B tech companies with proven demand, a high-value sale and a focused set of target accounts, usually already paying for HubSpot, Salesforce or Clay. | B2B companies with a large target market, high-value customers and a sales team in place to follow up on leads. | | Services | GTM Services for signal-based outbound, Account-Based Marketing, Paid Media, Content Engineering and RevOps. | Cold email, with list building, deliverability, CRM enrichment and syncing through OutboundSync. | | Who Picks Up the Conversation | Our operators qualify the reply and hand warm conversations to your reps. | Positive responses go to your sales team, which it expects to have in place before it starts. | | Where Your Setup Lives | Your own CRM and sending accounts, with Clay tables in your workspace or moved there once you’re on Clay. | It sets up the sending domains and inboxes, and lists domains, inboxes, Clay tables and lists as transferable to you. | ## Meet Frontal and Growth Engine X ### Frontal We’re a go-to-market partner for B2B tech companies, and we run more than one channel against the same accounts. Our operators handle signal-based outbound, account-based marketing, paid media, content and RevOps, all working off one account list in your own CRM and Clay. Our clients can start with the service that fixes their biggest gap and bring in others as pipeline grows, without hiring another vendor to run them. Because every service shares the same CRM data, a second one picks up where the first left off instead of starting over. **Tools we build with** Clay HubSpot Salesforce Smartlead HeyReach **Partner status** Clay Elite Studio Partner HubSpot Solutions Partner Salesforce Partner LinkedIn Ads Certified Google Partner ### Growth Engine X Growth Engine X is a done-for-you cold email agency, and everything it offers serves that one channel. It builds lists by studying a client’s best customers and finding companies that look like them, then tests a wide spread of campaign ideas before putting more volume behind the ones that work. Once a prospect responds, the conversation moves to the client’s own sales team. It often shows up on [outbound agency shortlists](https://frontal.so/blog/best-outbound-lead-generation-agencies), and buyers who also need ads, content or CRM work tend to weigh it against a broader partner like Frontal. **Tools they build with** Clay Claygent Prospeo OutboundSync Smartlead Instantly **Partner status** Clay Elite Studio Partner Partner profiles on Smartlead and Instantly \[ Coverage \] ## How Much of Your Go-To-Market Each Partner Covers The gap between Frontal and Growth Engine X shows up when you list every job your go-to-market needs done. Frontal covers outbound and the work around it from one shared account list, while Growth Engine X covers the cold email part and leaves the other channels to you. | GTM Work | Frontal | Growth Engine X | | --- | --- | --- | | Cold email | Yes. Signal-based campaigns run by our operators from your sending accounts. | Yes. Its core service, with up to 5,000 emails a day included. | | LinkedIn outreach | Yes, aimed at the same accounts as email. | Not listed. LinkedIn is used as a data source. | | Account-based marketing | Yes. Coordinated programs across outbound, ads and content. | Not listed. | | Paid media | Yes. LinkedIn and Google ads aimed at your target accounts. | Not listed. | | Content engineering | Yes. Founder and team content that warms the same accounts. | Not listed. | | RevOps | Yes. CRM data, routing, reporting and attribution. | CRM enrichment and syncing through OutboundSync. | | Reply handling | Yes. Our operators qualify replies and pass warm conversations to your reps. | Its best fit assumes your sales team works the responses. | Going with a cold-email-only partner usually means a second agency for ads and content, plus someone in-house to keep the CRM clean, each working from a different list. With Frontal, that work stays with one team, and you can add each service when your pipeline is ready for it. From our client work For Aircall, we built one self-refreshing market map of 3,655 accounts inside its own Salesforce over six months, so every channel works from the same current list. The [Aircall case study](https://frontal.so/case-studies/aircall) shows how it was set up. \[ Key differences \] ## Where Frontal Goes Further Than Growth Engine X Frontal and Growth Engine X can both put a sharp email in front of the right buyer. Only Frontal keeps going after the send, into the ads, content and CRM work around it and the conversations that turn replies into pipeline. 01 Strategic ### Channels That Reach the Same Accounts Frontal Outreach runs on email and LinkedIn, while paid ads and founder content warm the same accounts before and between messages. A buyer who has seen your ads and read your founder’s posts opens the next email already knowing who you are. Growth Engine X Cold email is the channel, and it runs that channel at scale, with its site reporting 8M+ emails sent a month for clients. Ads or content would sit with another vendor or your own team. 02 Operational ### The CRM Work Behind the Campaigns Frontal Our RevOps work cleans CRM data, fixes routing and sets up attribution, so leads land with the right rep and you can see which channel moved each account. Growth Engine X It enriches CRM records, including contacts it isn’t emailing, and syncs campaign activity through OutboundSync. Routing, reporting and attribution beyond that aren’t among its listed services. 03 Strategic ### Who Turns a Reply Into Pipeline Frontal A reply is where most outbound loses momentum, so we treat it as part of the campaign. Our operators sort each response, keep the interested ones moving and send them to your reps ready for a conversation, and every call outcome feeds the next round of targeting. Growth Engine X It lists a sales team in place as part of its best fit and says companies with no sales system to work its leads usually aren’t a fit, so your own team owns each conversation from the first interested reply. From our client work By week two of Palico’s outbound with us, 6 to 15 positive replies were coming in every week. Three of those [early replies became clients](https://frontal.so/case-studies/palico) within the first weeks. 04 Strategic ### The Number That Shows Up in Your Report Frontal Before launch, we agree with you on what a qualified opportunity means for your sales team, then follow each account through reply, meeting and opportunity in your CRM. Opens and send counts never make the report. Growth Engine X Results are reported in positive responses, and its site doesn’t define what makes a response positive. From our client work Playbook had never run outbound before working with us. Its first 20 days produced 20 opportunities, and the program reached [300+ positive replies](https://frontal.so/case-studies/playbook) over nine months. 05 Operational ### How You Get Started Frontal We scope every engagement on a 30-minute call with a senior operator, built around the gap you most need closed. Since no two setups look alike, prices come out of that conversation rather than a published list. Growth Engine X Its main site doesn’t show pricing, but the free test campaign application lists $6,500 to $10,000 a month for its services, as of October 2026. Clay’s partner directory adds a three-month minimum engagement. Qualifying companies can start with a free test, and teams scaling outbound they already run can book a call directly. From our client work Keragon brought us in for one job, opening conversations with potential partners. We kept two new [partner conversations](https://frontal.so/case-studies/keragon) a day coming for six straight months and gave its team back 100+ hours a month. \[ Which fits \] ## Frontal vs Growth Engine X: Which Partner Fits What You Need? Start with the work your team can’t get to today, then match it to a row. If you’re still deciding which channels deserve budget this year, our [GTM strategy framework](https://frontal.so/blog/go-to-market-strategy-framework) helps you set the order. | What You Need | Frontal | Growth Engine X | | --- | --- | --- | | Outbound plus ads, content or RevOps around it | Built for this, with every service aimed at the same target accounts. | Cold email only, so the rest needs a separate partner. | | A focused list of high-value accounts | Our core work. Accounts are tiered, timed on buying signals and worked across channels. | Below its stated best fit of 100,000+ contacts. | | Someone to manage replies before they reach sales | Included. Our operators qualify replies and hand off warm conversations. | Its best fit assumes your team does this. | | Clean CRM data and attribution across channels | Covered by our RevOps work. | CRM enrichment and syncing only. | | Cold email at very high volume into a market of 100,000+ contacts | Outside our focus. We send to the accounts that fit. | Its specialty, with backup domains kept warm so sending doesn’t stall. | ### Teams We’re Not Built For Frontal works best once your product has found its market and you know which accounts you want. If you’re still testing product-market fit, chasing the biggest send volume possible or need a guaranteed number of leads or meetings, another partner will serve you better. The same applies to one-off builds your team plans to run alone. Cold calling and intent data subscriptions sit outside what we do too. If you’re still unsure whether you need volume or a focused program, our ranking of [lead generation services](https://frontal.so/blog/best-lead-generation-services) lays out how the two approaches differ. \[ The real questions \] ## Frontal vs Growth Engine X FAQs ### Does Growth Engine X Offer Paid Ads, Content or RevOps? Its site lists cold email services, with list building, deliverability and CRM syncing around them, and no paid media, content or RevOps service. Frontal runs all three alongside outbound, off the same account list. ### Is Coldoutbound.com the Growth Engine X Website? Yes. Growth Engine X’s site runs at coldoutbound.com under the Growth Engine X name, with the same free test campaign for companies that qualify. ### Are Frontal and Growth Engine X Both Clay Elite Studio Partners? Yes. Clay’s partner directory lists both at Elite Studio, the top of its four tiers, and as the authors here, we’re one of them. With the tier equal, compare scope instead, which our guide to choosing a [GTM engineering agency](https://frontal.so/blog/gtm-engineering-agency) walks through. ### What Counts as a Positive Response in Cold Email? A positive response is usually a reply that shows interest, such as a request for details or an agreement to talk. Definitions vary by agency, so ask any partner how many of its positive responses became meetings and opportunities last quarter. ### Is Growth Engine X an AI Lead Generation Service? Growth Engine X is a done-for-you cold email agency that uses AI for research and copy, while its team runs the campaigns. Our [AI lead generation](https://frontal.so/blog/best-ai-lead-generation-services) roundup separates software from managed services like these. ### Can We Move Our Growth Engine X Domains and Clay Tables to Frontal? Usually, yes. Growth Engine X lists domains, inboxes, Clay tables and lists as transferable. We’d review the warm domains and tables first, carry over what’s performing and time the switch so sending doesn’t pause.
