By using CarlyEmail you agree to these terms. If you are agreeing on behalf of a company, you confirm you may bind it.

The service

CarlyEmail is an API for creating email inboxes and sending, receiving and managing mail through them, over REST and MCP. We provide it as described in the documentation.

Your account

You are responsible for what happens under your API keys. Keys are shown once and stored only as a hash — we cannot recover one, so keep them somewhere safe and revoke any you think has leaked.

You must give a working owner email address and confirm it. Until you do, your organization cannot send mail; that is a deliberate limit, not a fault.

You must be old enough to enter a contract where you live.

Acceptable use

This is a sending platform, so the rules that matter are about what you send. You may not use CarlyEmail to:

• Send unsolicited bulk email, or mail to addresses you have no permission to contact.
• Send phishing, malware, or anything designed to deceive a recipient about who it is from.
• Impersonate a person or organization you do not represent.
• Harass, threaten, or send content that is unlawful where it is received.
• Evade suppression — an address that bounced or complained is blocked, and routing around that is a breach of these terms rather than a clever workaround.
• Resell raw sending capacity as a commodity, or run an "email blaster" on top of the API.
• Probe, overload or reverse-engineer the service beyond what the documented API permits.

Building a product where your customers get their own inboxes is expressly fine — that is what pods are for.

Limits

Each plan carries inbox and sending limits, described in limits. We enforce them at inbox creation and at send. We may change limits with notice to the owner email on file.

We may throttle or suspend an account immediately, without notice, if it is causing harm — high complaint rates, obvious abuse, or activity that puts other customers' deliverability at risk. We will tell you why.

Your content

Your mail is yours. We claim no ownership of it.

We store and process it only to run the service — deliver it, show it to you through the API, and keep the delivery record. We do not sell it, share it for advertising, or train models on it. See the privacy policy for what is stored and for how long.

You are responsible for having the right to send what you send.

Payment

Paid plans bill monthly in advance through Stripe. Charges are not refundable except where the law requires, though we will look at a genuine billing mistake.

Cancel any time through the billing portal; you keep the plan until the end of the period you have paid for. Failed payment moves you to the free tier rather than cutting off access to mail you already have.

We may change pricing with 30 days' notice to the owner email.

Availability

We aim for the service to be available and to lose nothing, and the system is built for that — mail that cannot be processed waits and retries rather than being dropped. But this is a v0 API with no contractual uptime commitment. Do not use it as the only copy of anything you cannot lose.

We may change or deprecate parts of the API. Breaking changes to a documented endpoint get notice to the owner email.

Ending it

You can stop at any time; delete your data through the API or ask us to.

We may terminate for a breach of the acceptable-use section, for non-payment after notice, or if we stop offering the service — in which case we will give reasonable notice and time to export.

On termination we delete your data. Say so if you want it sooner.

Warranties and liability

The service is provided as is, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement.

To the maximum extent the law allows, SWH Labs LLC is not liable for indirect, incidental, special or consequential damages, or for lost profits, revenue or data. Our total liability for any claim is limited to what you paid us in the twelve months before it arose — which, on the free tier, is nothing.

Some jurisdictions do not allow these exclusions, in which case they apply only as far as permitted.

Changes

We will update the date at the top and tell the owner email about material changes before they take effect. Continuing to use the service after that is acceptance.

Governing law

These terms are governed by the laws of the Commonwealth of Massachusetts, USA, without regard to conflict-of-laws rules.
