The screenshot above is the accounts tab of the panel, with real accounts connected. You add your own accounts, and the number you run at once is up to you rather than up to us.
The work itself starts from a source. Point it at a group and pull the members, or search for groups from inside the panel if you don't have a target list yet. You can take members or the people actually posting, filter by when they were last seen, or simply paste a list of usernames you already have. Then you pair that source with your own destination and start the job.
While it runs you keep the controls. There's a cap on how many are added per cycle, the account steps back on its own if Telegram asks for a wait, the load is spread across your accounts rather than sitting on one, and you can check an account's standing before it does anything. Jobs are tracked in real time, several can run in parallel, and you can schedule cycles, pause, resume or delete a job, keep a blacklist, and read stats per account. Team seats with roles and webhook access come with the higher tier.
Packages are Starter $690, Professional $990 and Team $1,490, one payment with no renewals and 12 months of support. There's a free 24 hour demo if you want to try it before deciding.
