Great Email Verification That Cuts Bounces and Protects Your Domain
What do you like best about ZeroBounce?It’s great to be able to verify emails before sending, since it reduces the risk of hard bounces and helps protect your domain so you’re less likely to get marked as spam when doing cold outreach, which is wonderful. The main downside for me is that the process feels a little bulky: I have to upload spreadsheets, and it seems like it can only verify either personal or work emails one at a time. That means I end up doing the uploads twice. This may be related to how I’m using it and there could be a better way, but I haven’t found one yet.What do you dislike about ZeroBounce?I find uploading spreadsheets to be time-consuming and a bit bulky. If the columns don’t line up properly, it sometimes won’t read the information correctly, and I’m not sure if there’s a better way to handle that. Otherwise, the software itself does a great job of detecting incorrect emails.What problems is ZeroBounce solving and how is that benefiting you?It helps keep our domain healthy by preventing us from sending emails to incorrect or invalid email addresses.
