Marketing agencies need B2B leads that convert, not bounce. InboundLabs gives you 280M verified contacts with 98% deliverability. No annual contracts.
You’re running outbound for your clients. You’re also running outbound to find new clients. And somehow, both pipelines are leaking.
The culprit is usually the same: bad contact data. B2B contact data decays at 22.5% per year — meaning nearly 1 in 4 contacts in any database goes stale within 12 months. Email addresses alone churn at 23–30% annually. When your list is 18 months old, you’re essentially throwing darts in the dark.
For marketing agencies specifically, this creates a double problem. Bad data doesn’t just hurt your own prospecting — it tanks the results you deliver to clients, which tanks retention.
InboundLabs is built for exactly this use case. 280 million verified B2B contacts. 98% deliverability. Direct dials, not switchboard numbers. No annual contract required.

What are B2B leads for marketing agencies?
B2B leads for marketing agencies are verified contact records — including emails, direct phone numbers, and firmographic data — for decision-makers at companies that could either hire the agency or buy from its clients. Quality B2B leads include buyer intent signals that show when a prospect is actively in-market.

Most sales tools are built for one direction: your outbound to prospects. Marketing agencies operate in two directions simultaneously:
That dual-pipeline reality means data quality issues compound fast. A 15% bounce rate on your client’s cold outreach campaign doesn’t just mean missed meetings — it means a damaged sender domain, a frustrated client, and a churn risk.
According to research from Landbase, poor data quality costs organizations an average of $12.9 million annually, with companies losing approximately 15% of revenue directly attributed to inaccurate contact information. For an agency billing $3M/year, that’s a $450K problem hiding in your list hygiene.
Before comparing tools, let’s define what “good” looks like for agency use:
A good bounce rate is below 2%. Above 5% is a red flag that damages your sending reputation and, by extension, your clients’ domains. Most mass databases run 15–20% bounce rates. InboundLabs maintains 98% deliverability — verified, not estimated.
Switchboard numbers waste SDR time and signal to prospects that your data is stale. Verified direct dials to mobile and office lines get through to decision-makers in the first call attempt, not the fifth.
Marketing agencies serve specific niches — SaaS companies, e-commerce brands, B2B manufacturers. You need to filter by industry, company size, ARR range, tech stack, headcount growth, and geography. Spray-and-pray lists waste budget that should go toward creative.
