Connect Contact Form 7 to Mailchimp, Brevo, MailerLite & Klaviyo

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 83% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

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 declining trend compresses what a buyer would pay.

   The settings for this plugin aren’t its own page, but a page within each CF7 form. I’m not sure if that’s any more of a limitation than strange UX. The plugin creates a cmatic_daily_cron cron job that is set to run once daily but often gets stuck and won’t run and refuses to run manually. Again, it appears to function fine without it – but then what is that cron supposedly doing?Recently, there’s a new admin bar icon in the top bar, with a nag for upgrading. That alone is enough to make me not want to upgrade to pro (for some clients I use pro, for others there’s no budget for that).Finally, when navigating away from any CF7 page, if this plugin is active the browser warning “Changes you made may not be saved” shows – whether you saved or not, whether you changed anything or not. Anyway, its pretty good, but not great. (minus one star for the nag; minus one star for the browser warning and the cron job error). These errors make me doubt if its working and want to constantly audit the MailChimp list, but with dozens of sites using it, that’s a big task.

   Be Aware, once you signup for pro there is NO way of CANCELING the account. Which means they keep taxing your account every year! I am not sure how they can do this as this is not a subscription service and is illegal. We have tried to get in touch but they do not answer the emails. So it looks like now we need to go to the POLICE. Maybe they can answer here???

   BE AWARE of this plugin – It is now a SCAM! DO NOT SUBSCRIBE to premium as you will not be able to cancel. They NO LONGER provide support, the website does not work when you try to access your account, and they NO LONGER answer the emails but they still charge you and they make it very hard to cancel or change account details. VERY DISAPPOINTED – and can’t understand how this is allowed on the WordPress community! Now we will need to go to the bank to blacklist this user and account and look for another provider! READ REVIEWS BEFORE YOU COMMIT!! This topic was modified 3 years, 3 months ago by yannis06. This topic was modified 3 years, 3 months ago by yannis06.
