Free forever
The free tier covers the whole workflow at a small scale: 5 campaigns, 10 posts per month, and manual fill-only publishing. You also get unlimited group discovery, multi-account switching, side-panel mode, posting history, and secure Google sign-in — no credit card required.
Pro: monthly and annual
Pro removes every limit: unlimited campaigns, groups, posts, and schedules; all three publish modes (Manual, Confirm, Auto); and full scheduling with Once, Daily, Weekly, and Monthly cadences.
Monthly is $5.99 per month — about $0.20 a day. Annual is $57.60 per year (normally $71.88), which saves 20% and works out to two months free. Both plans start with a 7-day free trial.
What the free tier leaves out
Free includes Manual mode only. Confirm mode, Auto mode, and scheduling & cadences are Pro features — the three locks you will see in Settings.
Trials and billing
Every paid plan starts with a 7-day free trial. Cancel any time during the trial and you are not charged. Paid plans are billed in USD through Polar; your receipt arrives by email from Polar/Marbelona.
Manage your subscription — upgrade, change card, or cancel — from Settings → Manage billing, which opens the Polar customer portal. Plan changes always go through the portal.
Refunds
If GroupBlaster is not right for you, email i@marbelona.com within 14 days of a charge and we will refund it in full. The full policy is on our Refund Policy page, linked in the footer.
