01Who we are

discard.dev ("we", "us", "the service") is an independently operated developer tool providing a throwaway SMTP server that captures outbound email instead of delivering it. These terms form a binding agreement between us and you, or the organisation you act for ("you"). By creating an account or sending mail through the service, you accept them.

You can reach us at support@discard.dev for anything arising out of these terms.

02The service

discard.dev accepts SMTP connections on smtp.discard.dev and stores the messages your applications submit so you can inspect them in the portal. The essential characteristic of the service is that nothing is delivered onward: messages addressed to real recipients are captured and stopped, never relayed.

The service is intended for development, testing and quality assurance. It is not a mail provider, not a relay, not an archive, and not a backup. It must not be used as part of a production email path, nor relied on for the delivery, storage or preservation of any message that matters.

04Acceptable use

You agree not to use the service to:

Security research is welcome, but not against live infrastructure without our written agreement first. Write to support@discard.dev.

05Your content

The messages your applications submit remain yours. You grant us only the permission we need to run the service: to receive, store, index, render and return those messages to you, and to delete them under clause 6.

You decide what you send us, and you are responsible for it. Because captured mail is stored so it can be read back in a browser, do not send real personal data through the service. Use synthetic fixtures. If you do send personal data anyway, you are the controller of it, we process it on your instructions, and the terms in our Privacy Policy apply.

We do not read your captured messages except where strictly necessary to operate the service, investigate abuse, or comply with a legal obligation.

06Plans, limits and retention

Limit Free Pro
Messages per day 25 5,000
Message size 10 MB 25 MB
SMTP credentials 1 Unlimited
Retention 7 days 30 days

Messages over the daily limit are refused at the SMTP layer with a 550 response; messages over the size limit are refused outright. The daily counter resets each UTC day. Refused messages are not stored and do not consume allowance.

Retention is the period for which we undertake to keep a captured message available. After it expires a message may be deleted at any time without notice, and you should not assume anything is still there. You can delete individual messages yourself from the portal at any time. We may change these limits on notice under clause 13.

Downgrading from Pro to Free re-applies the Free limits, including the credential limit and the shorter retention window.

07Billing

The Free plan is free and requires no card. The Pro plan is a paid recurring subscription.

Paddle is the merchant of record for every purchase. Paddle.com Market Limited sells the subscription to you, runs the checkout, charges the card, handles tax and issues the invoice. Your purchase is therefore also subject to Paddle's buyer terms, and we never see or store your card details.

08Availability

We aim to keep the service up, but we offer no service level agreement and no uptime guarantee. The service may be unavailable for maintenance, for changes, or because something has broken. We may add, alter or remove features at any time.

This is a development tool. Do not place it on any path where an outage would harm you.

09Suspension

We may suspend or throttle an account, or revoke credentials, without prior notice where we reasonably believe it is necessary to protect the service or other users — for example on breach of clause 4, on unpaid fees, on suspected compromise, or where we are legally required to. Where we can, we will tell you why and what would resolve it.

10Termination

You may stop using the service at any time. To close an account and have its data erased, write to support@discard.dev from the account's registered address.

We may terminate this agreement on 30 days' notice, or immediately for material breach. On termination we delete the account's captured messages, credentials and account record, subject to the retention described in the Privacy Policy. Export anything you need before you go — raw .eml downloads are available from the portal while the account is live.

Clauses 5, 11, 12 and 14 survive termination.

11Warranties

The service is provided "as is" and "as available". To the fullest extent permitted by law we exclude all warranties, conditions and terms implied by statute or common law, including any warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement.

We do not warrant that the service will be uninterrupted or error-free, that every message submitted will be captured, or that a captured message will remain available for any particular period beyond the retention undertaking in clause 6.

12Liability

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any liability that cannot lawfully be limited. If you are a consumer, your statutory rights are unaffected by anything here.

Subject to that, we are not liable for loss of profit, revenue, business, goodwill, anticipated savings, or for loss or corruption of data, or for any indirect or consequential loss, however arising.

Our total aggregate liability arising out of or in connection with this agreement is limited to the greater of the fees you paid us in the twelve months before the event giving rise to the claim, or EUR 100.

You will indemnify us against claims brought by a third party arising from content you submitted to the service or from your breach of clause 4.

13Changes to these terms

We may update these terms. The version and date at the top of this page always identify the current text. For changes that materially reduce your rights or increase your obligations we will give at least 30 days' notice by email to the account address before they take effect. Continuing to use the service after that date is acceptance; if you would rather not accept, cancel and close the account.

14Governing law

This agreement, and any dispute arising out of it, is governed by the laws of Ireland and subject to the exclusive jurisdiction of the Irish courts. If you are a consumer resident in the EU or EEA, you keep the protection of the mandatory laws of your country of residence and may bring proceedings there.

If any clause is found unenforceable, the rest stands. Our failure to enforce a term is not a waiver of it. You may not assign this agreement without our consent; we may assign it to a successor of the business. These terms, with the Privacy Policy, are the entire agreement between us on this subject.
