SendTidings is a hosted reporting tool for agencies and freelancers that turns client analytics into branded monthly email reports. It connects to supported data sources, lets you choose the sections and branding, and sends reports on a recurring schedule.
The site positions it as a replacement for manual monthly reporting work: connect your data, design the template once, and let the system send the report on the first of each month. The product currently supports hosted use, with a self-hostable AGPL-3.0 version listed as coming soon.
