Introducing Trestle’s Phone Grading App for HubSpot: Improve Lead Quality & Boost Conversions
HubSpot users know that not all leads are created equal—invalid phone numbers, disconnected lines, and low-quality contacts waste time and hurt conversion rates. That’s where Trestle’s Phone Grading App comes in.
Our app seamlessly integrates with HubSpot to analyze and grade phone numbers in real time, helping you:
Identify bad phone numbers & emails – Detect disconnected or invalid phone numbers & emails before wasting outreach efforts.
Enhance lead scoring – Prioritize high-quality leads with accurate, contactable numbers & emails
Automate with workflows – Use HubSpot lists and workflow triggers to automatically grade and filter contacts.
How It Works
Trestle’s Phone Grading App assigns a contact grade to each phone number and email address based on real-time data, including carrier info, line type, and recent dialing activity. We also return an Activity Score to easily identify which phone numbers are disconnected.
If you collect emails from your contacts, we can grade those too! Here is a full list of what we will return for each contact:
- Valid Phone: Yes/No response
- Phone Activity Score: 1-100 response
- Phone Line Type: Will return the line type of the phone number (e.g., mobile, landline, non-fixed VoIP, fixed VoIP, etc.)
- Phone Name Match: Yes/No response
- Phone Contact Grade: Returns A, B, C, D, or F
- Valid Email: Yes/no response
- Email Name Match: Yes/no response
- Email Contact Grade: A, B, C, D, or F
You can easily run bulk grading via lists or set up automated workflows to grade contacts as they come in.
