Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

N/A

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. The recent download trend is too spiky to read.

Recent reviewers are happy with the plugin's validation and its Gravity Forms and multisite support, though a couple mention slow checks on less common domains and no reply from support.

    The option to validate the email, in WooCommerce in the checkout payment, does not work, I have even written several times and also sent a video so you can see the error.

    Fast for Public email but slow for other domains, example for: LIVE, GMAIL, HOTMAIL, YAHOO MAIL etc. takes about 4 seconds, but when comes to any other domains, the validation can take up to 10-20 seconds to validate. Thats my experience anywayzz. Works, but bit slow You get 100 free checks, BUT the paid plan is super cheap, minimum $10USD for 5000 checks and credits never expire. There’s other plans This topic was modified 4 years, 9 months ago by Jaso. This topic was modified 4 years, 9 months ago by Jaso.
