What I like about Proofy's **Spam Analysis** is that it helps identify email addresses that may trigger spam filters, improving deliverability and increasing the chances that emails reach the inbox.

I'm doing email marketing and get 1000's of email using scraping tools. Someone suggested proofy on reddit, I compared plans and I'm quite convinced that it is one of the best in term of value for money. The tool is easy to use, I use it only to verify emails.

I integrated Proofy into my GoHighLevel automation workflow, and it worked completely fine. Email verification runs smoothly in the background without any manual intervention. Solid tool, does the job reliably.

good company, email verification works.

Proofy has become a go-to in my workflow. I manage outreach for multiple clients in the home services space and list quality is everything — a dirty list tanks your sender rep fast. Proofy makes the whole process effortless. Upload your list, get a clean breakdown of valid, invalid, duplicates, and role-based addresses, done. No bloated dashboard, no upsell every time you click something. The pricing is the most straightforward I've seen — you know exactly what you're paying and what you're getting. Honestly refreshing compared to the bigger names in this space that nickel and dime you. If you're running any kind of outbound email operation and you're not cleaning your lists, you're leaving deliverability on the table. Proofy makes it easy enough that there's no excuse not to
