Terms of Service

Effective date: September 27, 2026

These Terms govern your use of Silo, the email marketing service at silomailpro.com and app.silomailpro.com (the "Service"), provided by Simpli Software LLC, 30 North Gould Street, Sheridan, WY 82801 ("we", "us"). By creating an account or using the Service you agree to these Terms on behalf of yourself and the organization you represent ("you").

1. The Service

Silo provides software to manage subscriber lists, design and schedule email, run sequences and automations, host signup pages, and report on results. Silo does not deliver your email itself. You connect your own sending provider (for example Amazon SES or an SMTP service), and all email is sent through your account with that provider, under that provider's terms. You are responsible for your relationship with, and fees owed to, your sending provider.

2. Accounts

  • You must provide accurate information and keep your sign-in credentials secure. You're responsible for activity under your account, including by team members you invite.
  • You must be at least 18 and able to form a binding contract.
  • The account owner controls the account, its data and its team. Team roles (owner, admin, editor, viewer) are managed by you.

3. Your responsibilities

  • You will comply with the Acceptable Use and Anti-Spam Policy, which is part of these Terms.
  • You will comply with applicable laws, including CAN-SPAM, CASL, GDPR, the UK GDPR and the ePrivacy rules that apply to you and your recipients.
  • You are the controller of your subscriber data and are responsible for having a lawful basis, including consent where required, to email every address you upload or collect.
  • You will keep a valid postal address in your account settings; it's added to your marketing emails.

4. Plans, fees and limits

  • The Free plan is free of charge within its limits. Paid plans are billed in advance, monthly (and annually once offered), through our payment processor, Stripe.
  • Plans are priced by the number of subscribed contacts and include a monthly fair-use send allowance, as described on the pricing page. We don't charge per email; your sending provider bills you for sending.
  • If you exceed your plan's contact limit, imports, API additions and broadcasts pause until you upgrade or reduce your contact count. Signup pages keep accepting subscribers.
  • If you cancel, or a payment remains unpaid 7 days after the end of the billing period, your account moves to the Free plan's limits. Fees already paid are non-refundable except where required by law. There are no refunds for partial periods; you can cancel at any time and keep your plan until the end of the period you paid for.
  • We may change prices with at least 30 days' notice; changes apply from your next billing period.
  • Prices exclude taxes, which you're responsible for where applicable.

5. Your content and data

You keep all rights to your content, lists and data. You grant us a limited license to host, process and transmit them only as needed to provide the Service, as described in our Privacy Policy. We don't sell your data or use your subscribers' data for our own marketing.

6. Third-party services

The Service connects to services you choose, such as Amazon Web Services, SMTP providers, Shopify, WooCommerce, Mailchimp, Kit, Zapier, Google and Facebook. Your use of them is governed by their terms. We're not responsible for their availability or actions, including a sending provider suspending your account with them.

7. Suspension and termination

  • We may suspend sending, or suspend or terminate an account, for a breach of these Terms or the Acceptable Use Policy, non-payment, a legal requirement, or activity that threatens the Service or others, as described in the Acceptable Use Policy. Where practical we'll notify you first and give you a chance to fix the problem.
  • You may cancel a paid plan at any time from Billing. To close your account entirely, or to get a copy of your subscriber data first, contact support@silomailpro.com.
  • After an account is closed we delete its data as described in the Privacy Policy.

8. Availability and changes

We work to keep the Service available and secure, but we don't guarantee it will be uninterrupted or error-free, and we don't offer a service-level agreement on standard plans. We may change or discontinue features; if we discontinue the Service entirely we'll give reasonable notice and help you get a copy of your data.

9. Disclaimers

The Service is provided "as is" and "as available". To the extent permitted by law, we disclaim all implied warranties, including merchantability, fitness for a particular purpose and non-infringement. We don't guarantee inbox placement, open rates or any particular deliverability outcome, which depend on your sending provider, your content and your recipients.

10. Limitation of liability

To the extent permitted by law, neither party is liable for indirect, incidental, special, consequential or punitive damages, or lost profits or revenue. Our total liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the claim.

11. Indemnity

You'll defend and indemnify us against third-party claims arising from your content, your lists, your email, or your breach of these Terms or applicable law.

12. General

  • These Terms are governed by the laws of the State of Wyoming, without regard to conflict-of-law rules. Any dispute will be resolved exclusively in the state or federal courts located in Wyoming, and both parties consent to their jurisdiction.
  • We may update these Terms. For material changes we'll notify account owners by email or in the app at least 30 days before they take effect.
  • If any part of these Terms is unenforceable, the rest remains in effect. These Terms, with the policies they reference, are the entire agreement between us about the Service.
