Salesbread is a b2b LinkedIn outreach agency that specializes in bringing clients 1 qualified sales lead per day. Since 2019, SalesBread clients have averaged a 19.98% reply rate with our ultra-personalized LinkedIn lead generation services.

And…

48.14% of those replies were either meeting requests or qualified sales inquiries on their product or service. Wondering how we achieve this?

Here’s our secret:

• Obsessive list building

• Ultra-personalized LinkedIn outreach (No sleazy sales copy)

• Following up consistently

• Asking for a booked call

At Salesbread, we don’t just stop at basic list building but look for patterns between your current buyers, and this helps us build look-a-like lists of prospects to go after.

We do this to understand and find your IDEAL target prospects.

We analyze your current customers through 34 business attributes and “signals.” This helps us find customers who need what you’re selling and have the buying power and budget.

The video below shows an example of how we would do this:

Our list-building process normally takes a week to perfect.

Once it’s perfect, and we have found the right people to reach out to at these accounts, we will then research each prospect on the list and send them a personalized outreach message.

We do this manually and don’t use any AI.

In fact, we have a full-time personalization expert whose sole job is to research prospects and find something very specific to mention in our messages.

(E.g., “By the way, I listened to your interview on the cold outreach podcast and appreciated your insights on why today’s quota-driven sales teams need to focus on quality, not quantity.”)

We actually look for something to either compliment the prospect on, mention a commonality, or ask them a question.

(You can read more about our CCQ method here.)

This captures the attention of our prospects and sets our messages apart from every other salesperson on the platform.

Next, we will follow up consistently with our prospects and ask for a booked sales call.
