Hey Vizi, we just did a similar work for our client but it was Facebook Messenger with Pipedrive integration. Privacy as always is something to be cautious about, especially with Meta's limitations on automated outreach. For Instagram, we looked into a few tools but most reliable platforms don't allow auto DMs to new followers directly due to API restrictions. That said, we’ve seen some accounts pulling it off using third-party workarounds, though it's a bit of a grey area. Curious to see if anyone here found a compliant way to do it.
I'd be happy to chat more about it.
