Groundhogg — CRM, Newsletters, and Marketing Automation

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. 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 small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.

   I’ve used Groundhogg on 4 websites so far. It does a whole pile of things that make it brilliant for communicating with our subscribers. The tags functionality, broadcast tools, and integrations are great. Adrian Tobey and Gregg Franklin offer great support, and when they have a problem, they are quick to alert their customers. Unlike many plugin providers Groundhogg are there to support their customers, even if it’s the customer’s error.

   A highly customisable CRM. It pretty well does all the basic stuff out of the box, but if you need more than that then you can add or customise most of the behaviours using the API etc. I’m not a web or PHP developer, but this has worked out for me in conjunction with Claude, though obviously takes a bit of time and some general software development expertise.

   I’ve been looking for free CRM and email marketing plugins over the years (I’ve been creating WordPress websites since 2007). After finding and then using Groundhogg for almost a year for small and medium businesses/organizations, I can say that I haven’t found any better value. I’ve used Hubspot, Salesforce, and a handful of other CRMs and Marketing tools/plugins but nothing compares to the value I found in Groundhogg. Try the free version of Groundhogg for yourself and see if it works! There are always limitations and issues, and such is the case with anything, however, the value and the cost cannot be compared to anything else I have found. If anyone wants to learn how to use Groundhogg, give me a shout.

   We have this product for about 3+ years. It is a great concept but some features are promoted as existing, although in reality are buggy or not completely functional as expected (maybe I have too hight expectations). The problems is, there is learning courve for it and you only realise some expected features or needed features aren’t there and it’s too late as you have it in production. What frustrates me and made me write this review is, I have tickets opened with them in their support section that are opened from 2024 (almost 2 years) and also there are tickets closed without a resolution. I would have expected in almost 3 years to see some of the features we complained about being fixed or new features added in this sense. For the money, ok but I would have loved to see a bit more attention to support and user voice in regards to what’s needed. For example, if you work as a sole individual with thsi CRM is ok-ish, but when you look integrating it in a company with several departments and each having multiple team members, you will struggle making it work, sharing data amongst the team members or keeping some sections private to each team/department.

   I have tried to use Zoho as my CRM with my WordPress site that relies heavily on WPForms. I love WPForms and would not switch away from it unless someone gave me a really good reason. The problem is that Zoho does not integrate easily/well with WordPress and WPForms. I have wasted a couple of thousands using Zoho developers to try and get things integrated. I also tried to work with Zoho directly and that was a bigger waste of time. Zoho sucks! And just when I was ready to chuck it in on using a CRM, I found Groundhogg. Right from the beginning, Groundhogg installed their App, configured it, and gave me the most incredible customer support. Whenever I had a question, they responded anywhere from within one hour to no more than a few hours (usually right away). If you have a WordPress site, and you’re doing business with it, you need a CRM. There is only one choice…Groundhogg! Adrian and Gregg will give you support that exceeds your expectations. Do I work for Groundhogg? No. Am I a fan? Absolutely! Give Groundhogg a try. You will be incredibly happy you did.

   I’ve been using GroundHogg for almost a year on an e-learning site and I’m very happy with the results. I was looking for a system that would offer: 1. WordPress integration. 2. Premium CRM features. 3. A better price. I found everything I needed with GroundHogg. Plus, I’ve always received excellent support from their customer service.

   No footer block is used. Add your signature and footer to the “Custom Footer Text.”Center the body of the email to style the default compliance footer, which has no margin and is left-aligned. Footer block used: Add custom replacement code at the end of the email. Then, style and align the footer block beautifully in the editor. Thank you, Adrian, for the meeting and for bringing up this solution. This topic was modified 9 months, 1 week ago by Steven Stern (sterndata).
