Fair Usage Policy

Unlimited where it matters. Generous ceilings only to keep the network healthy.

Muzero is built for teams who want to scale outreach without counting mailboxes. Every plan includes unlimited warmup and unlimited mailboxes, with team seats sized to your plan. The limits below exist for one reason only: to prevent abuse and protect the shared warmup network and deliverability of every customer. You will never see these numbers in your dashboard unless you actually approach them — and if you do, we'll simply reach out to raise them.

Phone-number ceilings are set at one number for every five mailboxes. Need more on any line? Contact usand we'll lift your limits.

What's genuinely unlimited

  • Warmup — every connected mailbox warms continuously, at no extra cost.
  • Campaigns, sequences, and sends — no artificial caps; your mailboxes send at full capacity.
  • Deliverability tooling — inbox placement, bounce, and blacklist monitoring run around the clock.

How automations work

Automations are the metered network and AI actions Muzero runs for you — finding a lead, importing a LinkedIn profile, enriching a contact, AI web research, or a minute of calling. Each plan includes a monthly pool that's shared across your whole team, and automations only deduct on success. Need more? Top up anytime or move up a plan.

Preventing abuse

The ceilings above let us stop bad actors from flooding the shared warmup network with disposable mailboxes, which would harm deliverability for everyone. Legitimate teams effectively never hit them. If usage looks abusive or is degrading the network, we may temporarily throttle it and contact you before taking any further action.
