"Zerobounce Delivers Fast, Accurate Email Validation and Cleaner Lists"

4.5/5

What do you like best about ZeroBounce?

Great app for finding suitable business emails, and it feels safe to use too. I used to work with hundreds of client emails from a database, but the conversion rate was very low because many addresses bounced, some went to spam, and some were simply fake. Zerobounce helped me filter those out and build a cleaner, more accurate list that converts much better.

Another thing I like is that it also helps in finding suitable emails for companies and people when their data is available. Even with heavy, bulky email lists pulled from directories, the processing is fast, the performance is amazing, and it feels like good value for money. I also appreciate the detailed categorisation of emails, such as spam, invalid, and more. Review collected by and hosted on G2.com.

What do you dislike about ZeroBounce?

The user interface has improved a lot, but it could still be better. Credits get used up very quickly, and when I’m working with bulky data it ends up feeling expensive. Even with use zerbounce, some emails still aren’t categorised correctly at times. Review collected by and hosted on G2.com.

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

I used to have a huge list of client emails, and the bounce rate was high. For me, the biggest help is being able to process bulky email IDs and get them sorted into clear categories like valid, invalid, and spam.

One of my clients works only in B2B, so finding suitable potential businesses was tough. With ZeroBounce, we built a clean distributor email address list that converted well.

When we had multiple emails and didn’t know which one could be a potential customer, its email scoring feature was very helpful. It lets us understand the engagement potential of contacts and strategise accordingly.

Many clients want to work with specific businesses, but sometimes online scam IDs show up. With the ZeroBounce email finder, this problem is solved. Review collected by and hosted on G2.com.
