Common Issues with Instantly

Instantly includes a built-in B2B lead database, but its data layer remains limited compared to platforms like Leadsforge or Apollo.

• Smaller database scope: SuperSearch covers about 450M contacts, but updates are slower and lack real-time firmographic or intent data.
  
  
• Limited enrichment: It verifies emails but doesn’t append LinkedIn profiles, titles, or phone numbers automatically.
  
  
• No live buyer signals: Instantly doesn’t track funding, job changes, or intent topics, so outreach timing may miss active buyers.
  
  
• Static records: Uploaded lists don’t auto-refresh or sync enriched data back into CRMs.
  
  
• Accuracy depends on verification credits: Validation is credit-based (0.25 credit per lead), so verifying large datasets costs extra.
  

In short, Instantly’s sending infrastructure is strong, but its data validation and hygiene layer still need careful management to maintain long-term deliverability.
