Perfect plugin

gwennyeeckels September 19, 2024

Works perfect. Easy set up.I also use FleuntCRM, Fluent Booking and Ninja socials. All works perfectly together.

No Support, No Documentation, Don’t Use

Stef September 18, 2024

After being told to use this app we started recognizing issues. We followed their minimal doc for Send Grid. However, emails for lost password are only being sent to the client’s domain emails and not others. I reached out to this group on Facebook and noticed no response. I came here to reach support queries and saw no response to lots of issues. I also emailed these people and their OWN email comes back bad. I don’t know how there are a ton of great reviews here. This app is horrible and no support.

It works and integrates well with other plugins.

joeduardoreyes September 16, 2024
