"Although it seems not showy, HuBuCo is by far one of the best verifying mail services around. Some of good things of this service are: cost, effectiveness, quickness to check emails, support service...I assert the hard bounces were below 1% with OK emails."

I use HuBuCo for all my customers and clients who need to validate their email lists. Quick and easy to use and the reports at the end are functional and easy to work with. (Jennifer R.)

This service was so helpful when I cleaned my email lists. I especially liked the reports and explanations of what the verification results mean. (Sarah, LA)
