01Agreement
These terms govern your use of SadaSend. By creating an account or sending email through the service you agree to them. If you are agreeing on behalf of a company, you confirm you have authority to bind it.
02Your account
- You are responsible for everything sent using your API keys. Treat them as credentials, not configuration.
- You must give us a working email address and respond to notices about deliverability or abuse. We will occasionally need to reach a human quickly.
- One person or company per account. Reselling SadaSend as your own email service requires a separate written agreement.
03Acceptable use
Email is a shared resource. What you send affects the deliverability of every other customer on the same infrastructure, which is why this section is stricter than you may expect and why we enforce it quickly.
You may not use SadaSend to send:
- Mail to recipients who did not ask for it, including purchased, scraped, rented, or appended lists.
- Phishing, credential harvesting, malware, or anything impersonating another person or organisation.
- Content that is illegal in the jurisdiction of the sender or the recipient.
- Mail that conceals its origin, forges headers, or evades unsubscribe mechanisms.
- Bulk marketing without a working one-click unsubscribe that you honour within two days.
04Deliverability thresholds
We monitor bounce and complaint rates per account and act on them automatically. These are not warnings we may choose to send — they are enforced by the platform.
| Signal | Threshold | What happens |
|---|---|---|
| Complaint rate | Above 0.08% | Warning in the dashboard and by email |
| Complaint rate | Above 0.10% | Automatic throttle on your sending rate |
| Complaint rate | Above 0.25% | Sending suspended pending review |
| Hard bounce rate | Above 5% | Automatic throttle |
| Verified domain | Missing or broken | Sending refused until DNS is corrected |
05Suspension
We may suspend sending immediately and without notice where we reasonably believe an account is sending unsolicited or malicious mail, or where continued sending would damage the deliverability of other customers. We will tell you why, and we will restore service as soon as the cause is resolved.
Where the issue is a rate threshold rather than abuse, we throttle before we suspend, and you keep dashboard and API read access throughout so you can diagnose the problem.
06Billing
- Paid plans are billed monthly in advance. Usage above your plan is billed monthly in arrears.
- You can cancel at any time; cancellation takes effect at the end of the current period and we do not refund partial months.
- We will give at least 30 days’ notice by email before any price increase.
- Fees exclude taxes, which are added where applicable.
07Service availability
We publish real-time status at status.sadasend.com. Scale plans include a service level agreement; Free and Pro plans are provided without one.
Email delivery depends on receiving mail servers we do not control. We will do everything reasonable to get your mail accepted, but no provider can guarantee inbox placement, and you should treat anyone who claims otherwise with suspicion.
08Your content
You own the content you send. You grant us only the limited licence needed to transmit, store and display it in order to operate the service — for example, rendering a message body in your own logs.
09Warranty and liability
The service is provided “as is”, without warranties of any kind to the fullest extent permitted by law. To the maximum extent permitted, our aggregate liability arising from these terms is limited to the amount you paid us in the twelve months preceding the claim.
Nothing in these terms excludes liability that cannot lawfully be excluded.
10Termination
Either party may terminate at any time. On termination we delete your data on the schedule set out in the Privacy Policy, except suppression records and anything we are legally required to retain.
