Pay only when the message lands in the Inbox. Start free, scale as you grow.
prepaid balance, never expires
managed pool
Only confirmed delivery to Inbox (not Promotions, Spam, Bounce). Verified via seed sampling or engagement signals (open/click/reply).
Managed: our warmed-up accounts, quick start, no setup. BYO: your SMTP/IMAP accounts, cheaper, requires setup.
Every creative passes a 3-tier pipeline (rules → AI → human review). The one-time $5 approval fee covers this. Required to protect our sender pools. Auto-approved workspaces are not charged.
You don't pay. Billing only on confirmed inbox placement.
No. The $50 signup credit and your balance don't expire. Top-ups are handled by our team while the beta runs (no payment gateway yet).
The beta runs with limited capacity: a few self-signup workspaces are active at a time, the rest join a waitlist and are activated as seats free up.
Traditional providers charge per send regardless of outcome. LDM charges only when the message lands in the Inbox.
