ZeroBounce is a great service! We use it every year to clean up our mailing lists before sending out holiday cards. It is very easy to use, fast, and gives detailed and accurate results including a clean list of emails that we can use with confidence on other plaforms like constant contact and mainlchimp! Great prices on the pay as you go option too! Thank you ZeroBounce!
Thank you, Juan Pablo. We truly appreciate your kind words and are glad you’re enjoying the service.
The verification process is really good and gives us authentication in the datasets. I would also suggest working more on your interface and also on pricing, so it will be easier for us to work for a longer period of time. A very good tool for email marketing and sales purposes.

Great tool, many options to go with (pay as you go, monthly sub...) really fast support by chat, and very efficient services! My Hard bounces rate go down from 6% to 0,2% !!
Thank you so much for sharing this wonderful feedback!

Our average open rates went from 7% to 20%+. At my current job, I inherited an older but very large email list with poor hygiene. We also had a large volume of new contacts per month. By adding zero bounce, I was able to eliminate over 10 spam traps and thousands of low-quality emails. We've seen our open rates and deliverability improve drastically as a result.
I like your customer service, very well, very kind, GOOD!
Thank you so much, Asher. We’re really glad to know you’ve had such a kind and positive experience with our customer service. That's so important to us. Your encouragement means a lot to the team. If you ever need anything, we’re always here (24/7) and happy to help.
Vladimir answered my support email on Thanksgiving night at 1:30AM. Amazing service and support! And the service is working great for me so far.
Thank you so much, Felipe. We’re really glad to hear Vladimir was there for you. We're always there for you: even in the middle of the night on a holiday.

I like this service because it clarifies understandable reasons for sometimes unclear server output. Helpful to know and for explaining fluctuations in the list.
Thank you, Judith. We're really glad to hear the service helps bring clarity to those confusing server responses.
