Telegram DMs - Analytics tool (metrics)

Hey fellas,

we're planning to leverage Telegram mass DMs to invite users to our Telegram channel, potentially our app. Despite extensive research, I haven't found any existing tools, bots, or similar solutions that effectively track key metrics for cold DMs. Metrics like: views, clicks, reactions, conversions etc. Our strategy involves testing various messaging approaches with different content versions and languages to see what works. And btw.how do you do it?
Thanks

Hmm anyone out there not doing the "close my eyes and hit send" approach to DMs? Or the "spray and pray" haha

Now actually wondering how you do it for example on Instagram or any other social with mass DMs?
