LinkDM is an Instagram marketing platform that enables brands and creators to automatically send direct messages to individuals who comment on their Instagram posts, ads, stories or reels!

LinkDM offers a completely free version with no usage limitations. The free version also allows users to attach and manage up to 3 Instagram accounts.

For an additional fee, users can upgrade to Pro, which includes access to premium features like auto post-tagging and ads automation, as well as the ability to manage up to 10 Instagram accounts. Pro costs $19 per month.

LinkDM connects to the Instagram API as a third-party developer. When a comment is received on a post, we receive the information from Instagram and automatically send the specified direct message back to the user.

LinkDM is a certified Instagram third-party developer and a member of the Meta Business Partner program. This allows us to connect directly to the Instagram API and provide our services to users while remaining 100% complaint with Instagram TOS (Terms of Service).

No, you do not need to add a credit card to use the free version of LinkDM. The free version is available to use without requiring a credit card or any other payment information. However, if you decide to upgrade to the Pro version, you will need to provide a valid payment method in order to access the additional features and functionality.
