Stop dialing dead numbers! If you’re an SDR or sales leader tired of wasting time on outdated, inaccurate contact lists, we have big news for you. Salesfinity has partnered with Upcell.io to bring you the best mobile phone data available—right into our AI Parallel Dialer.
The Problem: Cold Calling in the Dark
Let’s face it: cold calling is hard. Most SDRs start their day by searching for contacts on tools like Apollo or ZoomInfo, filtering by job title or company size. They add contacts to their call sequence and hope for the best. But here’s the truth:
Bad Data: Many contacts have outdated or incorrect phone numbers. That means lots of calls end up in voicemail or, worse, never connect.
Low Connect Rates: With only 3% of the market ready to buy, most calls never turn into real conversations.
Wasted Effort: SDRs are forced to keep building new lists every day, as warm prospects slip away without proper follow-up.
This “spray and pray” method might get you a few quick wins, but over time it makes every day tougher. Your team is busy dialing, but without the right numbers, they’re not connecting with the right people.
The Solution: Compound Growth Through Data Enrichment
At Salesfinity, we believe in making every call count. That’s why we built our Compound Growth Platform—to help you not just dial more, but dial smarter. And today, we’re taking that promise even further with our new integration with Upcell.io.
What’s New?
We’ve added Upcell.io to our data waterfall, which now includes seven different data providers. Upcell.io is known for its extremely accurate mobile phone data. With this integration, our SmartEnrich feature lets you push a button to fully enrich your contact lists and prospects with the best mobile numbers available.
How It Works
Waterfall Data Enrichment: When you upload your contact list into Salesfinity, our platform automatically checks seven data sources—including Upcell.io—to verify and enrich phone numbers.
Phone Number Enrichment: This means every contact has the most up-to-date mobile number, so you don’t waste time dialing dead numbers.
Boosted Connect Rates: With accurate data, our AI Parallel Dialer can connect you to real prospects faster. This improves your cold call connect rate and, in turn, builds a warmer, more effective sales pipeline.
Seamless Integration: Upcell.io works with the same ease as our other data providers. Just one click with SmartEnrich, and your SDRs are ready to make calls that matter.
The Benefits for SDRs and Sales Leaders
Our new integration isn’t just a tech upgrade—it’s a game changer for your team. Here’s why:
Faster Connection Speeds: With enriched, accurate mobile data, your calls are more likely to reach live prospects.
Higher Cold Call Connect Rate: By dialing the right numbers, you see a significant boost in call deliverability. That means more live conversations and fewer wasted dials.
Improved Prospecting: With reliable phone number enrichment, you can focus on strategic outreach and nurturing warm leads.
