Bulk Number Marketing in B2B vs B2C

[nusaiba127]

While often associated with B2C, B2B businesses are also leveraging bulk messaging more effectively in 2025.

B2B Use Cases:
Lead nurturing sequences

Event invitations

Product update rollouts

Demo follow-ups

You can even use LinkedIn phone number extraction tools vp r&d mailing leads (like Skrapp or Lusha) to build opt-in B2B contact lists for bulk campaigns.

Pro Tip: Combine Voice + SMS
With AI-powered voice broadcasting, many brands are now sending a combo message:

A personalized voice call (recorded or AI-generated)

Followed by an SMS with a link or offer

This double-layer approach has shown up to 30% higher conversion compared to SMS alone.
