Verified, ICP-matched lead lists that give your cold email campaigns something real to work with, built for B2B SaaS companies.
A cold email campaign is only as good as the list behind it. Grow X builds verified, ICP-matched lead lists for B2B SaaS companies, so your outreach is talking to the right people instead of guessing.
Why list quality decides everything else
Great copy and perfect deliverability setup can’t fix a bad list. Scraped or outdated data drives up bounce rates, which damages domain reputation, and generic contact sourcing means your message reaches people who were never a fit in the first place. Most deliverability problems that look technical actually start with the list.
- A verified, segmented lead list matched to your defined ICP
- Enriched records with firmographic and technographic data
- Spam trap and role-based address removal
- Formatted export ready for your sending or CRM tool
- Ongoing hygiene checks for active lists
ICP definition
A tightly defined ICP produces a smaller
We start by mapping out
exactly who you sell to: industry, company size, tech stack, job titles, and the specific triggers that indicate buying intent. A tightly defined ICP produces a smaller, more accurate list than a broad one, and smaller-but-accurate consistently outperforms large-and-generic.
Verification and cleaning
Every email address is run through verification before it ever gets loaded into a sending tool. We remove invalid addresses, role-based inboxes, and known spam traps, since a single spam trap hit can damage domain reputation for weeks.
Segmentation
Lists get organized by the variables that actually change your messaging, company size, industry vertical, job function, so your sequences can be personalized by segment instead of running one generic message across everyone.
It depends entirely on your ICP and target volume. A tightly defined ICP for enterprise SaaS might produce 500 to 1,000 highly relevant contacts, while a broader mid-market ICP could produce 5,000 or more. We'd rather build the right list than the biggest one.
We run every address through automated verification tools that check deliverability status, catch role-based and disposable addresses, and flag known spam traps before the list ever gets used in a campaign.
Yes. We can build lists around a specific target account list, mapping multiple contacts per company across relevant roles, rather than a broad single-contact-per-company approach.
Both. We offer one-time list builds for specific campaigns, and ongoing hygiene plans for teams running continuous outbound who need their list refreshed regularly.
List building sets the foundation. Grow X also handles email deliverability, copywriting, and full campaign management for B2B SaaS companies. Book a free consultation to talk through your ICP.
