"Enterprise AE using Prospect.io"
What do you like best about Overloop?

The Chrome Extension is very simple and is incredibly easy for importing leads to Salesforce.

What do you dislike about Overloop?

It's good for commercial teams, but has proven to be very poor at servicing teams focused on Enterprise companies. When you get away from standard (first.last@, etc...) email formats and start adding things like middle initials, numbers, etc... it struggles immensely.

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

It was originally brought on to solve the problem of the large amount of time our commercial team was spending prospecting and manually inputing data to Salesforce.

"Marketing associate increasing lead database for 1 year so far with Prospect IO"
What do you like best about Overloop?

I love that Prospect IO is a Chrome extension, so any website you go to, you can simply click the extension button, and it'll scan contact information for you. I also appreciate the LinkedIn feature. It keeps track of people you've already "prospected" - so you can stay organized and don't lose credits.

What do you dislike about Overloop?

There are often malfunctions with the software. It has trouble loading, or it simply doesn't work sometimes. I often have to uninstall and re-install the Chrome extension to get it to work again.

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

We've significantly increased our lead database by using Prospect IO.

"No more reliable than Email Hunter"
What do you like best about Overloop?

Integrates with LinkedIn to create Prospect record in Salesforce.

What do you dislike about Overloop?

Salesforce integration is unreliable and required a workaround to even function when prospecting outside US. For a European-based product this was a disappointment.

"Prospect.io is not a marketing tool"
What do you like best about Overloop?

Tools to help find or qualify emails, CRM capability and good contact filtering options.

What do you dislike about Overloop?

Lack of unsubscribe feature, lac of list management and the a mail limit of 400 emails sent (total)/day.

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

Our team was looking for a drip email marketing software that could manage and score our leads. The UX was poor, there were typos and the email editor was not robust. Overall: Pricing plans modelled after how many emails you can send a day was an odd one.

"Was great for a long period, then had stopped using because of bugs"
What do you like best about Overloop?

Overall the software can help you save a lot of time, it takes a little time investment up front but saves a lot of manual work.

What do you dislike about Overloop?

Had these bugs which made me stop using it: - Always disconnecting my email addresses and not working, and didn't notice it wasn't working for a while. - Their typing field crashes a lot, cutting/pasting/indenting is pretty buggy - Search function in the app doesn't always work - Pretty slow functions - Sometimes no answer to a question about bugs

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

I used to fill a lot of automation gaps in my sales process. When it was working a little smoother, it was great to save time on prospecting clients.

"Has promise, but a long way from being market ready"
What do you like best about Overloop?

Hugely responsive customer support team. Very easy to chat with and helpful with answers. It's easy to upload lists, and they offer an email verification service that checks for invalid addresses on upload.

What do you dislike about Overloop?

Honestly, there's almost nothing to like. The UI is challenging, the system behaves unexpectedly (eg. you think a campaign is paused or archived but it keeps sending emails), you can't schedule multiple campaigns in advance because one contact can't exist in multiple campaigns, there's a limit of 400 emails sent per day (which is usually fine but can be frustrating in certain circumstances), there's no unsubscribe option/link, there's no clear indication who has received a campaign once the last email has been sent, it doesn't show you lists of who bounced, responded, clicked. It's really only in its early stages. There are numerous typos throughout the application making it feel unpolished and not market ready.

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

We need a reliable email service provider that integrates with the rest of the marketing stack .
