What do you dislike about Callbox?

Occasionally, we have to overcome a prospect’s initial perception that the outreach is insincere because the first contact is made by an SDR rather than someone directly from our company. Review collected by and hosted on G2.com.

"So far so good, a good number of positive meetings booked, where we have demonstrated our product"

4/5

What do you like best about Callbox?

The feedback regarding the campaign success weekly is useful. The research time spent really helped, they work collaboratively with us to understand the business, present the right tone and message etc Review collected by and hosted on G2.com.

What do you dislike about Callbox?

although the weekly emailed stats are great, it would be nice to have a dashboard available to access realtime info, and a collated view of the project so far. The customer support team and the intended audience might not have the same culture. A call centre in the UK/US with people who know the local rules and customs of the target audience could help customers understand what they want and talk to them better. Review collected by and hosted on G2.com.

Recommendations to others considering Callbox:

Take the time to ensure the messaging is right for you. The team will review and make the relevant changes until it's on point. Review collected by and hosted on G2.com.

What problems is Callbox solving and how is that benefiting you?

Affording us the resource of an outbound sales team to spark the initial interest in our products with our chosen vertical of target businesses for our small team of software consultants to then demonstrate the solution. This benefits us being a small company with no current resource to run a campaign internally of this scale. Review collected by and hosted on G2.com.

"Good quality pipeline from cold outreach"

5/5

What do you like best about Callbox?

They are very professional and deliver at scale. In our case, sales people gave the final feedback about the quality, and they were very happy. They do that by levering data collection by technological means. They just being smart. Review collected by and hosted on G2.com.

What do you dislike about Callbox?

Callbox's database in Europe is not the best for our use case. Review collected by and hosted on G2.com.

Recommendations to others considering Callbox:

I would recommend them and work with them myself when possible. They deliver above expectations in quality and quantity. Review collected by and hosted on G2.com.

What problems is Callbox solving and how is that benefiting you?

Callbox worked with us on business development in the US for our niche B2B 3D printing products. This is a very technical and complicated persona, which is extremely hard to find. Callbox managed to provide a good stream of high-quality leads, despite no background in 3D printing. Review collected by and hosted on G2.com.

Recommendations to others considering Callbox:

Im a solo lead on the marketing/ticketing team and i am often stretched in different directions. With the team at Callbox i just need to tell them the end goal and they do the rest. They understand what needs to be done, how it needs to be done and It gives me more time to focus on other important things. I really appreciate a high performance the team like them. I have already recommended them to 3 more projects ran by others in my company and will continue to recommend them. Review collected by and hosted on G2.com.

"Professional, great service, flexible"

5/5

Friendliness, flexibility & takes initiative. Schedules and plans often change, especially when building new businesses. Callbox helped to accommodate these changes to suit our needs. Review collected by and hosted on G2.com.

Not applicable. Nothing to complain about. Review collected by and hosted on G2.com.

Recommendations to others considering Callbox:

Do consider Callbox, particularly if you need help building the funnel of leads. Partnering with them is a great way to complement your existing lead gen efforts to meet your sales targets. Review collected by and hosted on G2.com.

What problems is Callbox solving and how is that benefiting you?

My company wanted to build the funnel of sales qualified leads. We lack an inside sales team and having sales do lead gen was not scalable and cost effective. Leveraging callbox helped us focus on our core strength in sales and give us more to spend with customers, building relation and closing deals. Review collected by and hosted on G2.com.
