Services for MASS cold DMs on Instagram?

Given the nature of business I'm in, I'm looking to send out MASS outreach over Instagram DMs. Ideally, sending out messages that go out to thousands of people (hopefully in the 'requests' folder).

My company has budget to spend - we're just really looking for the right partner here that will help us do this effectively.

Is there an agency and/or tool you recommend here?

Check the BHW Marketplace - Social Media Section

There are reputable services that offer it here: https://www.blackhatworld.com/forums/social-media.200/

I have the tool too.
