I’ve been using this tool for about a year now. It’s very reliable and has helped us prevent bouncing by 20%. It helps our clients to address incorrect emails on the spot. It has many integrations that I recommend leveraging via API. We use it on Boost.Space and Make.com but it’s available on several other no-code automation platforms. I suggest using power mode when running verifications on API. The quick mode is often inaccurate. API Power mode is quite helpful though, most often resulting in a deliverability score. We have purchased multiple accounts on all tiers for this tool as it’s become a core part of our daily operations. Highly recommended for contact validation in marketing and patient email accuracy in healthcare.
