Terms of service.
Last updated July 2026. The rules for sending, receiving, and building on Milesender.
Using Milesender
You may use Milesender to send and receive transactional email through the accounts, domains, and credentials you control. Sandbox sending requires no verified domain; production sending requires a domain that has passed SPF, DKIM, and DMARC verification.
Acceptable use
No unsolicited bulk email, no sending on behalf of a domain you don't control or haven't verified, no using Milesender to distribute malware, phishing content, or anything illegal in the jurisdictions you send to or from. We reserve the right to suspend sending on a workspace that generates abuse complaints or spam-trap hits above provider-safe thresholds.
API keys and credentials
You're responsible for keeping API keys and SMTP credentials secret. Scope keys to the minimum access a given service needs — a key with send-only access can't read your logs or rotate other keys. Rotate immediately if a key is exposed.
Rate limits and fair use
Sandbox keys are rate-limited to protect shared infrastructure. Verified production domains scale with your plan. We'll warn you before throttling and never silently drop a queued send without surfacing it in your delivery logs.
Service availability
We target the uptime published on our status page for API, SMTP, and inbound routing. Scheduled maintenance is announced in advance where possible. We are not liable for delivery failures caused by receiving-provider policy (spam filtering, greylisting) outside our infrastructure.
Termination
You can delete your workspace at any time from Settings, which stops billing and schedules data deletion. We may suspend or terminate a workspace that violates acceptable use, with notice where the violation isn't actively harming deliverability for other customers.
Liability
Milesender is provided as-is during this stage of the product. Our liability for any claim is limited to the fees you paid in the 3 months preceding the claim. We are not liable for indirect or consequential damages, including lost revenue from undelivered email.
