Pricing that scales with you. Not against you.

Newsletter is priced by contacts on your list — your monthly send allowance scales with your contact volume (4× contacts on Essential, 8× on Professional, 12× on Business). Transactional is priced by raw email volume, regardless of contacts. Use Newsletter for marketing campaigns, Transactional for API-triggered sends like password resets and order confirmations. Most teams use both — same account, same Bridges.

Essential is the simplest, cheapest tier — designed for predictable budgets. If you exceed your allocation, sending pauses until you upgrade or wait for next billing. Pro and Business plans allow overages at a transparent per-email rate (visible in the configurator above). Essential plans on the Transactional track also cap at 100K emails/month — high-volume senders should pick Pro or Business.

If your account is set to Allow Overuse, sending continues past your plan allowance instead of pausing — and the overused quota is invoiced on your billing date, at the transparent per-email rate shown in the configurator above. That invoice must be paid within 7 days of its creation. If Allow Overuse is off, sending simply pauses at your plan ceiling until your next cycle or an upgrade — no surprise charges either way. You choose which behaviour fits your operation.

Yes — anytime. Upgrade or downgrade from your Mumara ONE account, and the change is prorated against your current cycle. You can also switch tracks (Newsletter ↔ Transactional) if your sending pattern changes.

Dedicated IPs (and Pools, and Bridges-to-Pool binding) are included on Professional and Business plans. Buy IPs from inside the platform; we handle warm-up automatically and monitor reputation continuously. Essential plans use shared sending infrastructure.

Mumara AI is included on every plan with a starter quota of credits. Three quality tiers — Mumara AI Fast (cheapest), Mumara AI (default), Mumara AI Advanced (highest quality) — let you balance cost and output. Top up credits anytime from your billing panel. AI Content Tags (the auto-rewriting differentiator) is gated to Business tier.

Yes. Mumara ONE has a free tier — 100 emails/day, 100 contacts — so you can build your first campaign before paying anything. No credit card required to sign up.

Volumes above 5M contacts (Newsletter) or 5M emails (Transactional) need custom pricing. Same for compliance-heavy industries, multi-region requirements, and anything with an SLA negotiation. Talk to sales — we tailor each engagement.
