It's the only tool I've tested so far which delivers on its promise, at a super convenient price. I've never seen a better email checker.

very high deliverability rate after the emails were checked by HUBUCO and we received good sender scores inside Sendgrid. the software is easy to use. credits are handled well.

not certain. at one point I didn't like the way reports were shown in the interface, but they've corrected the problem. At the moment it seems fine.

The results are pretty good. Not certainly industry best, but for smaller campaigns, its good enough. I hope they would keep upgrading and adding the features.

The catch-all email filter doesn't work that well. It's kind of important for me. Also, they are improving the result, but I would love them to improve faster.

It was not useful to me, I was really dissapointed

It didnt actually work, the cleaned list had so many bounces it was a waste of money

I found HuBuCo to be good, simple, got the job done. And the pricing was competitive, which is always nice.

I like the ability to carve out the Okay emails from the rest, and to queue up many lists at once for cleaning

I'm impatient with technology in general, always finding it difficult to wait for a process to complete.
