Hey buddy! Right now, I'm engaged in a similar approach of using Instagram mass direct messaging to promote CPA offers. What I want to share with you is that Instagram is a promising platform, but it can be quite challenging to maintain multiple accounts for spamming. These accounts require careful nurturing, such as a proper warm-up process and implementing clean strategies like incorporating sleep time and spacing out the delivery of each direct message. Lastly, if you manage to discover a profitable niche on Instagram, you can expect a significant conversion rate. Feel free to ask me any questions you may have, my friend!
