"Great tool! Up and running immediately, responsive customer service and great customisation!"
What do you like best about Overloop?

For the price point, nothing beats it. Prospect.io offers a super quick and easy solution for prospecting and lead management. The platform itself is exceptionally intuitive, the customizations available are simple, and the customer service is rapid. I noticed a bug in the system - they had it fixed within 24hours. It doesn't have in-built calendar scheduling or texting options, but it's straightforward to use zapier to link it up to almost anything. The BD team were up and running with prospect.io within a day!

What do you dislike about Overloop?

It's not got the frills that a larger provider would offer. For our purposes, it's of no concern, but depending on the size of your business, it might be a consideration.

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

Prospecting new business, lead management and automation.

"Great Service and support"
What do you like best about Overloop?

As s a Prospect.io client I love the most that every time I have a question it is well replied to with articles, examples, and even video calls. The support team, in our case Alexandra (most of the time), takes the time to really read and understand your needs or questions and to resolve them.

What do you dislike about Overloop?

I would love to be able to add to my emails more design to make them look better and engage better with my audience.

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

The most important thing for my team is that we save a lot of time with automation. The process is like magic, I can not think of myself doing this manually again. And of course, the email finder is the best tool ever!

"Excellent New Business Platform"
What do you like best about Overloop?

Allows you to keep all your new business prospects in one place, email them in a highly targeted manner and trace and track their responses. Extremely easy to use interface. Enables you to import your own prospect lists or search and import from Linkedin, which is very useful indeed. Create 'automations' for sending pre written emails with time lapses in between that you can tailor as you wish. Excellent online support that respond to queries in a informative and friendly manner promptly.

What do you dislike about Overloop?

Email sourcing can sometimes be frustrating. You need to use common sense and check the validity of your emails otherwise you can get a lot of bounces. I'm not always able to work on new business and sometimes I don't use all my credits. It would be good if the packages were more flexible. So if you don't use all of your credits - they could be carried over into the following month or your account credited in some way.

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

I use Prospect.io for new business prospecting. It keeps all my new business prospects in one place and enables me to monitor them quickly and easily. I've recently had some extremely positive responses from prospects, which I'm currently following up that I'm fairly certain will convert into sales.

"The Perfect tool for Personalized Prospecting & Persistence"
What do you like best about Overloop?

Prospect.io is a perfect tool for both prospecting and for sending emails via automation in a personalized manner. We love the tool since its a one stop solution for our company and we do not know how we would ever do sales without it. Prospect.io is a lifesaver and we have had great success in not only mining clients to find the right contact but also to send emails which are personalized in the process such as the new automation. Overall 5 stars!!!

What do you dislike about Overloop?

Nothing to dislike. Only feature addition we would suggest is that if we could have a list of prospects that emails are being sent in a particular day or particular week i.e. next email to be sent on a date. That's all.

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

As mentioned, it's cut down our time to find and reach out to new prospects by 75% or more. Really effective tool and a one-stop solution which is economically viable for us

"A superstar SDR in app form. Thank you!"
What do you like best about Overloop?

I'm into my fifth year now as a customer (between my last couple of roles) and cannot rate this platform highly enough. Professionally, this application helped me 'arrive' as a B2B salesperson and just at a time when I was beginning to doubt whether pivoting from working as a marketer was a good idea too! Whether you work for a start-up trying to put their first 10 customers on the board or for a £30 million+ turnover business, Prospect is where you can put everything you've learned from outbound sales leaders seamlessly into practice. Above all else, I like that it's a half way house between automation and human diligence when it comes to sending sales prospecting campaigns (you aren't having to put your trust in someone else's list or a spammy bot that is prone to misfiring and making you look amateur). Their customer success team are brilliant and if you let them in, they'll guide you in how to write subject lines and copy that gets responses. I like that it integrates but sits at arms length from your CRM until such a time two way contact with a prospect has been established (nothing worse that a pipeline full of c**p!). The Chrome extension for Linkedin is an excellent tool for making sure you're constantly topping up your supply of new decision makers in your ideal customer profile. This is a big call because it won't be true in 100% of cases. But from here on in, if someone gave me the option of an 'expert-led' PPC campaign or Social campaign or using Prospect.io to diligently target the right individuals and book meetings, I would pick this 95% of the time. You know who you're hitting and you are always in control of what's said and who it goes to.

What do you dislike about Overloop?

Bounce rates. This is an industry-wide obstacle and one you just have to accept as a challenge from the get go. This used to really frustrate me in Prospect but there is a simple fix. By making it a general rule that you always add 30% more prospects to a campaign that you need, you offset what is likely to be the quantity of people you get an OOO reply from, or hard bounce because the email is incorrect or soft bounces because you've emailed someone new and not landed in their primary inbox. The reality is you truly get out what you put in, so if you sit there and don't get creative with your messaging and don't invest time in structuring your campaigns and lists, all you'll end up with is great lists of prospects sitting there gathering dust and most likely decaying in terms of data quality. Like anything, you must invest focused time in figuring out what lists of prospects you need and what messaging is appropriate for them and running at least one campaign every week. If you stick to this, you'll gradually get better with your tone of voice and will absolutely generate so many more qualified prospects. And more importantly, they'll be the best quality prospects you've ever generated. Just focus on quality and not quantity and it'll be one of the best investments in sales automation you ever make.

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

I'm booking more discovery calls. Which then progress to more formal meetings and progressing the exact target businesses I want to sell to through my pipeline. Repeatedly and predictably throughout the year.
