Support
SupportBasicStandardStandardPriorityPriorityDedicated

Every plan includes the web app, the iOS and Android apps (coming soon), rolling address names, and the usage and event log.

Support: every plan can write to us from the app or by email, and we aim to reply within one business day. Requests are answered by support level: Priority first, then Standard, then Basic. Dedicated support is set out in the Enterprise agreement.

What scales

What changes as you move up.

Worker devices

Unlimited on every paid plan. A Worker is not a seat, and devices are never billed.

Email addresses

The number that meters. Every address counts, whether or not a device holds it. Deleting one frees its place immediately.

Domains

Shared domains are grouped by plan, and an account reaches its own group plus every group below it. Paid plans get a shared domain free accounts never reach, as well as the free one. Every shared domain is vetted before we add it. Scale and Fleet can also bring 10 and 50 of your own.

Retention

Mail is held 1 to 90 days, set per address and 7 by default, then deleted. Storage is not billed separately.

Address names

Roll names on every plan, like maya.holt@ or harbor-supply42@. From Scale you can also type any name, like sam@.

Management & API

Bulk management, tags, API keys and webhooks arrive at Operator. Audit history arrives at Fleet. AI agents, sending from the API and your own domains arrive at Scale. Teams arrive at Fleet.

Billing

Questions about plans.

Yes, on every paid plan. Mailcycle is built to put private email on every device you own, so devices are not billed. A Worker is not a paid seat. You can pair two thousand phones on the $15 plan.

Email addresses, and the management and automation around them. A device that connects to one costs nothing extra.

Yes. Two thousand Workers sharing 250 email addresses on Operator is a normal setup. Addresses move between devices whenever you want, and you decide which devices receive which addresses. If you need more addresses than your plan holds, upgrade.

One device is enough to try the product. Any paid plan removes the cap.

Every address your account creates, whether or not it is currently assigned to a device. Unassigning an address does not free its place; deleting it does, immediately. Deleted addresses are retired and never reissued to anyone.

For $19 a month instead of $15: AI agent inboxes, sending from the API, four times the email addresses, three times the mail received, five times the daily sending, ten of your own domains, addresses you name yourself, full API access and priority support. Operator suits code that receives mail and reacts to it through the API and webhooks; Scale suits code and agents that also send.

Nothing extra. Agents are included on Scale and above, and like devices they are not billed. An agent's addresses count toward your plan like any others, and it sends up to 20 messages an hour, more on Fleet and Enterprise.

Yes: three email addresses, one device and 3,000 messages a month. Free receives mail; sending starts at Personal. It has no time limit and needs no card, email address, name or password. Before you upgrade: paying by card, or through the App Store or Google Play, links a real identity to your account id in that provider's systems. Paying in cryptocurrency usually does not. The account stays anonymous to us either way.

Creating an email address beyond your plan's limit is refused, with a message saying why. Each plan also includes a message allowance: 3,000 a month on Free, 50,000 on Personal, 250,000 on Operator, 750,000 on Scale and 4,000,000 on Fleet, counted in fixed 30-day periods. Once it is used, new mail is refused until the next period starts, and senders are told so. Single messages over 25MB are refused on every plan. Pairing a device is refused only on Free, which pairs one. Free receives mail only. Paid plans send within a daily limit: 20 a day on Personal, 50 on Operator, 250 on Scale and 1,000 on Fleet. At the limit, sending pauses until 00:00 UTC and receiving carries on.

On the web, by card through Polar, which bills monthly as merchant of record and adds sales tax or VAT where it applies, or in crypto through NOWPayments. Card checkout asks for an email address for the receipt; we never see it. Once the iOS and Android apps reach the stores, Apple or Google will bill the subscription instead, and card and crypto will not be offered there.

Yes, provided the email addresses you hold fit the smaller plan. If they do not, the change is refused and you are told how many to delete. Paid plans do not cap devices, so devices never block a move between them. Moving to Free needs one paired device or fewer. Moving to Free during a period you have paid for stops the renewal and keeps your plan until that period ends, and you can change your mind until then. Moving between two paid plans starts a new paid period and is paid for. A subscription bought in the iOS or Android app is cancelled in the App Store or Google Play instead. See how addresses are counted.

Yes, on the web, by card or in cryptocurrency. Top up your account balance by any amount from $15 to $2,000, and your plan takes its monthly price from that balance every 30 days until it runs out. The balance is spent before a card: when it covers a period, the card is not charged for it, and no period is paid for twice. A balance buys Mailcycle plans and nothing else: it can't be withdrawn, transferred or exchanged, and it doesn't expire while your account exists. You can cancel a top-up within 14 days and get back what you haven't spent. After that, the Refund Policy says when the rest is refunded, including if we close your account or you ask before deleting yours.

In Plans & Billing, choose Cancel subscription, on the web or in the iOS or Android app. A card subscription can also be cancelled in Polar's customer portal. The plan runs to the end of the period you paid for, nothing more is charged, and the account then moves to Free. A card renews on Polar's monthly billing date; a crypto payment covers 30 days and does not renew by itself; a balance renews the plan every 30 days until it runs out. If you subscribed in the iOS or Android app, cancel in the App Store or Google Play, which the app opens for you; if you also have a balance, it pays for the plan again when that subscription ends, so move to Free too to stop completely.

Deleting your account cancels a card subscription at Polar at the same moment, so nothing more is charged. If it can't be cancelled, the account is not deleted and the app tells you. A subscription bought in the iOS or Android app is not cancelled by deleting the account: cancel it in the App Store or Google Play first, or the store keeps charging. Money you paid into your balance and haven't spent is refunded if you ask before deleting; after that, the balance is deleted with the account. Step by step: mailcycle.email/delete-account.

A day after an unpaid renewal, the account moves to Free and anything over Free's limits is paused for 21 days. Extra devices disconnect, API keys stop, and extra email addresses, including those on your own domains, can't send. Mail to them is still accepted and held. Pay within the 21 days and your plan comes back with everything on it, and the held mail arrives. If not, what was paused is deleted with its held mail, and the account stays on Free, which you can upgrade from whenever you like.

Yes. Card through Polar and crypto through NOWPayments are both live on the web. Every account still starts on Free, and nothing is charged until you choose a paid plan.

Start on the free tier.

Three email addresses and one device, with no time limit. No card, name, password or email address needed. Any paid plan connects as many devices as you like.
