Warm Outreach

Case Study: SaaS Warm Outreach for ore booked meetings

Every SaaS spams its new users with emails.
Most of them go unread.

It's even worse when a decision-maker signs up for your service and goes unnoticed or gets lost.

That's where warm outreach comes into play.

We helped neuroflash (Germany's #1 AI content suite) overcome this obstacle.

The result?
More booked meetings with the right people.

Social Recruiting

Case Study: For Social Recruiting Agencies

Kellerdigital is a social recruiting agency specializing in craftsmen. One of the most important channels for acquiring new customers is “cold” emails.

The agency approached us with an idea:
“Can we download Indeed job ads and obtain the names of the managers and their emails?”

The hypothesis was that those willing to spend money on job ads are more likely to spend money on social recruiting, and clearly, they have a significant need to fill positions.

As a result, 5% of the companies scheduled an appointment, up from 1% in regular campaigns.
