Terms of Service
01The service
justsmtp provides an SMTP relay for transactional email. We accept messages over authenticated SMTP at smtp.justsmtp.com, verify the sending domain belongs to your account, and hand messages to our upstream infrastructure provider for delivery.
Receiving is a second, optional service. Point a verified domain's MX at us and we accept, store and show you the mail addressed to it; it stays off until you switch it on for that domain, and we never publish an MX record on your behalf.
02Accounts
Sign-in is delegated to epass, our identity provider: you authenticate there and come back here with a session, so we hold no password of yours. You are responsible for the epass identity that opens this account and for every SMTP credential pair minted under it. Credentials are shown once at creation; we store only a one-way hash.
03Acceptable sending
Transactional and expected mail only. The full policy is the Acceptable Use document, which is part of these terms. In brief, you must not send:
- unsolicited bulk email, purchased lists, or "re-engagement" campaigns to stale addresses;
- content that is unlawful in your jurisdiction or the recipient's;
- mail from domains you do not control.
Sustained bounce or complaint rates materially above network norms may result in throttling first, suspension second. We contact you before suspending unless abuse is active.
04Your data
Message bodies exist in memory during relay and are not retained after the upstream provider accepts them. The activity log keeps envelope metadata, the subject line, delivery events and upstream SMTP responses, for the retention window of your plan (7, 30 or 90 days). The Privacy Policy sets out what that means in detail.
Mail you receive is different, and has to be: we store the message so there is something to show you. The original, its headers and its attachments are kept until the receiving retention window expires, and each message's own page says the date it goes.
05Billing
Plans are billed monthly in advance by send volume. Sends beyond your quota are refused with a temporary failure (SMTP 452) rather than billed as overage. Upgrades take effect immediately; downgrades at the next renewal.
06Availability
The service is provided with commercially reasonable effort. On paid tiers we target 99.9% monthly availability of the SMTP endpoint; Enterprise agreements carry a written SLA with service credits.
07Liability
To the maximum extent permitted by law, our aggregate liability in any twelve-month period is limited to the fees you paid us in that period. We are not liable for indirect or consequential damages, including lost profits or lost data.
08Changes
We may update these terms with 30 days' notice by email to your account address. Continued sending after the effective date is acceptance. If you do not accept, stop sending and we will refund any prepaid, unused period.
