Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

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.

medium confidence

Est. annual revenue

≈$2.1K range $490–$8.9K

Est. acquisition value

≈$7K range $1.2K–$40K

A small install base leaves thin data to model from. The range spans more than 10x because wp.org publishes install counts as broad bands, and conversion and price compound on top. Read the midpoint as an order of magnitude, not a valuation.

How we estimate this

Assumptions

  • Free → paid conversion. 0.5%–2% of active installs pay for the pro tier. Typical for freemium WordPress plugins; the real rate varies a lot by product.
  • Annual price per customer. $49–$149 a year, typical for Email & Marketing plugins rather than this plugin's own pricing.
  • Acquisition multiple. 2.5x–4.5x annual revenue, the going range for small WordPress-plugin businesses, stretched a little because downloads are growing.
  • Install base. 2K–3K active installs, from our install estimate (wp.org only publishes the floor).

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.

    Nowhere did I see the 500 subscriber limit, not until I investigated the logs when I wondered why it wasn’t sending. Uninstalling.

    Great plugin with excellent support! This is one of the few newsletter plugins that works well and allows you to send PDF attachments with your message. Recently, we encountered a problem sending newsletters. We couldn’t figure it out and contacted Tribulant for advice. The support team was very friendly and quickly resolved the issue.

    I have used this plugin for quite some time. But it was tiresome to set up and to customize. And I newer really was sure how the newsletters would show up when received by customers. I tested it, but sometimes the header would not show up.I finally left it and opted by a online newsletter/email system, that is sooo much easier to handle.

    Not happy with the harrassing notice every time I log in to WordPress to leave a review. Also, the output HTML is extremely junky. Other than that, the free version more or less meets functionality.

    Had a problem with the plugin, got some strange errors on cloning newsletters with content areas and also on sending through Mailgun api. Opened ticket in Tribulant support and after a good week they had it fixed. Great service.

    I’m rooting for this one to get better. When functional, it can be good. That said, its functionality has proved to be rather volatile at times. Regarding customer service, there’s room for improvement. I have received some help from them and it’s been appreciated when it came through. That said, the predictability of timely responses isn’t there. That can be frustrating when issues arise (and they often do). This topic was modified 3 years, 2 months ago by dave10001.

    Our email system has been through many different companies trying to get out of spam folders and into the inbox. all of them said they guaranteed results. but the only results were to be listed on spam lists because of shared IP address or entire IP blocks being listed and we just happen to be in a bad IP network. once we started using Tribulant our numbers to the inbox almost quadrupled because we were using our own server and not a service. And after their support team showed us how our site was slow and how to fix it, along with the updates they have helped us with regarding our send rate issues, i couldn’t be happier with the software or their service. we have even transferred from our old hosting service to tribulants hosting for a much faster and flexible system then our old expensive “daddy”. as to the software itself… its very flexible and has many features that more expensive services do not have. the ability to use your hosting server or an external smtp server for sending makes it useable if you already have a SMTP service you send through. the bounce and unsubscribe features are automatic when setup correctly and make you fully compliant with the BIG 4 mail services (gmail, aol, hotmail, and yahoo) along with all the rest as far as removal of unhappy recipients. The Newsletter Creator is simple to learn and use as well as fully customizable to make it look and feel like a part of your website…or be something completely new each mail you send. the mailing lists being a separate list than the website user list was a major factor for us but its ability to link to a site user would be very useful in others cases. stuff i haven’t even got to tinker with yet are the ability to customize the sign up and list management pages for the subscribers. or the subscription to multiple lists for different send rates (day/week/month) or products or whatever… and the cost makes it a tool that can grow as you do and not kill your bank account just to try. and the MANY more features i haven’t list here, are the reason im leaving this long review. I hope this helps someone make a decision… because Tribulant helped us, Im sure they could help you.
