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

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. A declining trend compresses what a buyer would pay.

    Installed this on a new client site without realizing it was a “trial” plugin. After we reached the end of the “trial,” I had ZERO access to the forms I had created. Only way to get access was to pay their over-the-top monthly / yearly fees! Needless to say, I will NOT be subscribing.

    Used this plugin for ages, very easy to use. Ran into a problem today so I emailed support, and a lad called Andrew got back to me in a matter of minutes with an easy solution. Great product and support.

    The Mailmunch app is easy to install, but their documentation did not inform me that when they added a name to my new product mail list, they would remove that name from other existing lists. You would think this would be properly documented! I lost hundreds of names from dozens of other lists. No-one can help me restore my lists. I asked Constant Contact for help but they refused as I did not use their native app. Constant Contact claims that Mailmunch is a “shoddily built API that uses capturing based on cached data” So, neither Constant Contact nor Mailmunch really gives a damn about their customer.

    This is perfect plugin to integrate constant contact in your WP site. It allows you to create nice looking forms/pop-up and adds your subscribers to Constant Contact lists. They also send you an email with weekly summary of your contact lists. Highly recommended!

    I find it verging on unethical when a supplier makes it really easy to sign up for their service, but when you want to cancel, there is no functionality on their website to cancel your subscription. No problem. I’ll send an email to their billing support email. Only to get an email back informing you that this email address is not monitored and that you have to use one of their other contact methods. Still eager to resolve the issue without too much fuss (like with most other subscriptions for plug-ins on WordPress) you go to the chat line. Only to be informed that billing queries can only be handled by telephone. So even though you live in South Africa, you make an international phone call to cancel your membership. Once you’re on the line, you have to tell your story to at least three different people until you get transferred to the correct “cancellations” department (while those international phone minutes are ticking away.) Eventually you speak to the right person and you are assured that your membership will be cancelled. Only – two months later – you get charged for the renewal of your membership. And the process repeats itself. You cannot email or resolve it via their chat “helpline.” So you are forced to make another international telephone call and you think that this company is sailing very close to the “too unethical to ever do business with again” border and you feel that you should warn other users about their practices.
