Customer Success Manager Mid-Market (51-1000 emp.) 8/6/2025 "SpamKill Highly Effective for Eliminating Bot Attacks" 5/5 What do you like best about SpamKill? Since meeting Mihir (SpamKill Founder & CEO) at Keap's "Let's Grow Summit" in 2022, I (and most of Keap's customer-facing employees that I know of) have been recommending SpamKill as the #1 solution for eliminating spam bots for Wordpress forms, Gravity forms, etc. I have never heard a single complaint after recommending SpamKill and have heard over and over again that it is very effective at ensuring no more bot attacks! Thank you, SpamKill, for taking great care of our Keap customers! Kelly Householder (Infusionsoft / Keap / Thryv CSM since 2012) Review collected by and hosted on G2.com. What do you dislike about SpamKill? Currently there is a limitation on Keap's side where it doesn't work on our Keap Max version, I expect that once Keap pushes an update to allow HTML code in our form builder, that SpamKill will be able to work there too. Review collected by and hosted on G2.com. What problems is SpamKill solving and how is that benefiting you? Our customers notify me of bot attacks on Keap's webforms. Captcha fails to work anymore and other products have been unsuccessful. SpamKill offers a solution that stops hackers and bots from entering false contact data into webforms, saving our users money and stress in managing bad contacts by eliminating new fake submissions.

My clients use it and it works." 4.5/5 What do you like best about SpamKill? Having a dedicated tool that does NOTHING other than staying in front of the latest attacks is invaluable. The amount of energy that goes into new, sneaky, and malicious Bot attacks is unreal and it requires a team that eats, sleeps, and obsesses over them to protect your list. SpamKill works, and it's one less thing my clients have to worry about. Review collected by and hosted on G2.com. What do you dislike about SpamKill? It doesn't work well with iframed pages. Perhaps an update will fix that. Review collected by and hosted on G2.com. What problems is SpamKill solving and how is that benefiting you? Email issues take up a lot of my time and are a hassle for my clients. Bots are getting very crafty and the classic tools are insufficient.
