The problem
Why your commercial emails are not getting through
Finding business emails is one of the biggest challenges for any B2B sales team. Having a list of email addresses is not enough: you need those emails to be real, active and belonging to the right person. Without verified contact data, your B2B email marketing strategy is destined to fail. As HubSpot explains in its guide on data enrichment, appending and verifying contact records is the foundation of any successful outreach.
Every bounced email damages your sender reputation. Every message that reaches the wrong person is a lost opportunity. And worst of all: contact data degrades 25-30% every year, meaning that list you bought 6 months ago already has thousands of invalid emails. Close CRM outlines eight essential steps for building a sales process where clean email data is the starting point for every stage.

Verified data vs. unverified data
This is what the difference looks like between a record with complete data and one with partial or incorrect data. Poor data quality also affects negotiations, as Gong.io reveals when analyzing common negotiation mistakes that cost deals:

2
Use a verified data source
Reliable data sources verify emails before delivering them. That means fewer bounces, better deliverability and more responses.
3
Personalize your approach
Having the right email is just the first step. What you write matters as much as who you write to. A personalized email multiplies responses.

A single bounced email can damage your entire domain reputation. The quality of your contact data directly determines the effectiveness of your entire commercial strategy.

Is it legal to send commercial emails to businesses?
Yes, as long as you comply with applicable regulations (GDPR in Europe, CAN-SPAM in the US). Emails must be professional, include an unsubscribe option and not be misleading. Using verified data reduces risks.
What percentage of emails are valid in a typical database?
Search Google Maps and press Start. Vonsel gathers the business results as you explore the map, going beyond the pins you can see at a glance. Pause, continue and save your search when you are ready. Google Maps does not provide business emails. Vonsel visits the available business websites to find published emails, additional phone numbers and links to up to 118 supported social networks and other platforms. What it finds depends on what each website publishes. Keep businesses on a map, organise them by stage, edit their details and use a Kanban board, calendar, notes, actions, tags and custom fields. Free holds 20 businesses unlocked. Start holds 800, Pro 4,000 and Scale 20,000.
