Effective date: March 25, 2026
By accessing or using Maillayer (maillayer.com), operated by MVP Stack LLC, you agree to be bound by these Terms of Service. If you do not agree to these terms, do not use the service.
Maillayer is a transactional email API service. It allows developers to send transactional emails — such as password resets, order confirmations, and account notifications — via a REST API. Maillayer is not a marketing email platform.
You are responsible for maintaining the security of your account credentials, including your API keys. You are responsible for all activity that occurs under your account. You must provide accurate information when creating your account and keep it up to date.
Maillayer is for transactional email only. You may not use the service to send bulk marketing emails, newsletters, promotional campaigns, or unsolicited messages (spam). You may not send emails to purchased or scraped lists. Violation of this policy may result in immediate account suspension or termination.
Your plan determines your monthly email volume and rate limits. Emails exceeding your plan limit will be rejected. We reserve the right to throttle or restrict API access if usage patterns indicate abuse or place excessive load on our infrastructure.
Paid plans are billed monthly or yearly through Stripe. All fees are non-refundable unless otherwise required by law. You can upgrade, downgrade, or cancel your plan at any time from the billing page. Changes take effect at the end of the current billing cycle.
Your use of Maillayer is also governed by our Privacy Policy, which describes how we collect, use, and protect your data.
You may close your account at any time. We may suspend or terminate your account if you violate these terms, abuse the service, or engage in activity that harms other users or our infrastructure. Upon termination, your data will be deleted in accordance with our Privacy Policy.
Maillayer is provided "as is" without warranties of any kind. MVP Stack LLC is not liable for any indirect, incidental, or consequential damages arising from your use of the service. Our total liability is limited to the amount you paid us in the 12 months preceding the claim.
We may update these terms from time to time. If we make material changes, we will notify you via email or through the service. Continued use of Maillayer after changes take effect constitutes acceptance of the updated terms.
