I’ve tried several email validation tools to keep our large blog subscriber list clean and our bounce rate low. Opportify’s bulk email validation was easy to use and really made a difference. As you know, blog subscriber emails can often cause issues, but with Opportify we reduced our bounce rate from 28% down to just 2% by filtering with the Email Insights “is deliverable” data. Their price is really good. Review collected by and hosted on G2.com.

They don’t yet offer many integrations. For instance, with WordPress. Review collected by and hosted on G2.com.
