1. Definitions
- Service — the WebinarOS software available at webinaros.ai and app.webinaros.ai, including registration pages, campaign automation, content tools, audience segmentation, deliverability monitoring, and reporting.
- Customer Infrastructure — the SMTP servers, mail relays, sending domains, subdomains, DNS records, IP addresses, mailboxes, and any other systems or accounts you own, lease, or control and connect to the Service.
- Third-Party Platforms — Zoom, Microsoft Teams, Google Meet, your CRM, your calendar, and any other external service you authorize the Service to connect to.
- Customer Data — all data you upload, import, generate, or transmit through the Service, including contact lists, registrant records, campaign content, and engagement data.
- Recipients — the individuals you contact or register through the Service.
2. The Service
WebinarOS is an add-on, not a replacement for your webinar platform. You continue to host on Zoom, Teams, or Meet, and you continue to send from your own email infrastructure. We layer registration, promotion, reminders, and reporting on top.
We grant you a non-exclusive, non-transferable, revocable right to access and use the Service during your subscription, for your internal business purposes, subject to these Terms.
We may modify, add, or remove features. We will not materially reduce core functionality during a paid month without notice. Beta or preview features are provided as-is and may be changed or withdrawn at any time.
The Service is for business use only. It is not offered to consumers, and you must be at least 18 years old.
3. Your infrastructure — your responsibility
This section is important. Read it carefully.
The Service sends email through Customer Infrastructure that you provide and control. You are solely responsible for procuring, configuring, securing, paying for, and maintaining that infrastructure.
We are not responsible or liable for:
- The health, uptime, performance, capacity, or security of your SMTP servers, mail relays, or hosting
- The registration, renewal, expiration, transfer, suspension, or seizure of your domains and subdomains
- Your DNS configuration, including SPF, DKIM, DMARC, MX, and reverse DNS records
- The sending reputation of your domains, IP addresses, or mailboxes
- Whether your messages are delivered, deferred, throttled, filtered to spam, or rejected by any mailbox provider
- Your domains or IPs being added to any blocklist, blacklist, or reputation service
- Suspension or termination of your account by any mailbox provider, registrar, hosting provider, or ISP
- Data loss, downtime, or breach originating in your infrastructure
- Any act, omission, outage, price change, or policy change by your infrastructure vendors
Deliverability depends on factors outside our control — your list quality, sending history, content, recipient engagement, consent practices, and the unilateral decisions of mailbox providers. We make no representation, warranty, or guarantee that any message will reach any inbox.
Our warm-up tooling, reputation monitoring, and deliverability reporting are diagnostic aids only. They report signals; they do not guarantee outcomes. Acting on or ignoring them remains your decision and your risk.
You are responsible for maintaining valid credentials and authorizations. If your credentials expire, are revoked, or stop working, campaigns may fail to send, and we are not liable for the consequences.
3.1 Managed email infrastructure add-on
If you purchase our managed email infrastructure add-on, we will provision and administer sending domains, inboxes, and SMTP configuration on your behalf for the additional monthly fee then listed on our pricing page. In that case Section 3 applies to the portion of infrastructure you still control, and we will use commercially reasonable efforts to configure and maintain the portion we provision.
Even then, we do not guarantee deliverability, inbox placement, sender reputation, or freedom from blocklisting, and Section 14 (Disclaimers) and Section 16 (Limitation of Liability) apply in full.
4. Third-party platforms
The Service connects to Third-Party Platforms only when you authorize it. Those platforms are controlled by their providers, governed by your agreements with them, and may change, break, deprecate their APIs, rate-limit us, or terminate access at any time.
We are not responsible for the availability, accuracy, security, or conduct of any Third-Party Platform, or for any loss arising from an integration failing, syncing incorrectly, or being discontinued. Maintaining your own accounts and licenses with those providers is your responsibility.
5. Accounts and security
You must provide accurate registration information and keep it current. You are responsible for all activity under your account, for safeguarding credentials, and for your users' compliance with these Terms. Notify us at [email protected] immediately if you suspect unauthorized access.
We may refuse registration, or suspend or close accounts, at our discretion where these Terms are breached.
6. Customer Data and content
You own your Customer Data. We claim no ownership in it.
You grant us a worldwide, non-exclusive, royalty-free license to host, copy, transmit, display, and process Customer Data solely to provide, secure, support, and improve the Service and to comply with law. This license ends when the data is deleted, except for backups pending routine deletion and any copies we must retain by law.
You represent and warrant that you have all rights, consents, and lawful bases necessary for us to process Customer Data as contemplated, and that your Customer Data does not infringe any third party's rights or violate any law.
For personal data, you are the controller (or business) and we are the processor (or service provider). Our processing is governed by our Privacy Policy and, where applicable, our Data Processing Addendum, available on request.
We may generate aggregated and de-identified statistics from use of the Service and use them to operate, benchmark, and improve our products. Such data will never identify you, your Recipients, or your Customer Data.
7. Acceptable use and anti-spam
Your use of the Service is governed by our Acceptable Use & Anti-Spam Policy, incorporated here by reference.
You are the sender of every message sent through the Service. You are solely responsible for compliance with all applicable law, including the CAN-SPAM Act, CASL, the GDPR and UK GDPR, the TCPA, and all US state privacy laws.
You represent and warrant that:
- You have a lawful basis and any required consent to contact every Recipient
- You did not purchase, scrape, rent, harvest, or otherwise acquire your lists without permission
- Your sender identification, subject lines, and message content are accurate and not deceptive
- Every marketing message includes a functioning unsubscribe mechanism and a valid postal address
- You will honor unsubscribe requests promptly and will not re-contact suppressed addresses
You will not use the Service to send unlawful, deceptive, harassing, infringing, malicious, or sexually explicit content; to distribute malware or phishing; to circumvent authentication or filtering; to reverse engineer, scrape, resell, or white-label the Service without our written consent; to exceed reasonable usage in a way that degrades the Service for others; or to test, probe, or attack our systems.
Suspension. We may throttle, suspend, or terminate sending or the account immediately, without refund, if we reasonably believe you have breached this Section, or if your activity threatens the security, reputation, or lawful operation of our platform or our other customers.
8. AI features
The Service uses third-party AI models to generate first drafts of landing page copy, invitations, reminders, and follow-ups.
AI output may be inaccurate, incomplete, biased, outdated, non-compliant, or similar to output generated for others. You are responsible for reviewing, editing, and approving all AI-generated content before it is published or sent. Nothing is sent on your behalf without your action.
We make no warranty as to the accuracy, originality, non-infringement, or fitness of AI output. Do not rely on it as legal, financial, medical, or professional advice. As between you and us, you own the output you approve and use, subject to these Terms and the applicable model provider's terms.
Do not submit sensitive personal data, regulated data, or third-party confidential information into AI prompts.
9. Fees, billing, and refunds
Subscription fee: billed monthly in advance, according to the tier you select — Starter ($250/month), Growth ($500/month), or Scale ($1,000/month), as described on our pricing page. Optional add-ons, including managed inboxes ($9/inbox/month), are billed at the rates listed there.
Payments are processed by Stripe. You authorize us and our processor to charge your payment method the full subscription fee on each monthly renewal date until you cancel. Your subscription renews automatically each month.
All fees are non-refundable. We do not provide refunds, credits, or prorated amounts for partial months, unused time, unused features, downtime, deliverability outcomes, blocklisting, integration failures, or cancellation mid-cycle. This applies whether cancellation is initiated by you or by us for breach.
Fees are exclusive of taxes. You are responsible for all sales, use, VAT, GST, and similar taxes, excluding taxes on our income.
Failed payment. If a charge fails, we may retry, and we may suspend access until payment clears. Accounts left unpaid for 30 days may be terminated and their data deleted.
Price changes. We may change pricing on 30 days' notice by email. Changes take effect at your next renewal. If you do not accept a price change, cancel before that renewal.
Chargebacks. Initiating a chargeback rather than contacting us first is a breach of these Terms and may result in immediate termination.
10. Term, cancellation, and termination
Term. These Terms start when you first accept them and continue for as long as your subscription is active.
Cancel anytime, for any reason. You may cancel through your account settings or by emailing [email protected]. Once you cancel, we will not bill you again.
Cancellation takes effect at the end of your current paid month. You keep access through that date. Consistent with Section 9, cancelling mid-month does not produce a refund or credit for the remainder of that month.
Termination by us. We may suspend or terminate immediately for breach of these Terms or the Acceptable Use Policy, non-payment, unlawful use, or conduct that risks harm to us, our other customers, or Recipients. We may also terminate without cause on 30 days' notice, in which case we will refund any prepaid fee covering the period after termination — the only circumstance in which a refund is given.
Effect of termination. Access ends, running campaigns stop, and scheduled sends are cancelled. You may export Customer Data for 30 days after termination; after that we delete or return it as described in our Privacy Policy. Suppression and unsubscribe records may be retained. Export your data before you cancel.
Sections 3, 6, 7, 9, 12, 13, 14, 15, 16, 18, and 20 survive termination.
11. Support
We provide support by email at [email protected] during standard US business hours. Support does not include configuring, repairing, or administering Customer Infrastructure or Third-Party Platforms.
12. Intellectual property
The Service, including all software, interfaces, templates, documentation, trademarks, and branding, is owned by us and our licensors and protected by intellectual property law. Except for the limited access right in Section 2, no rights are granted.
You will not copy, modify, translate, reverse engineer, decompile, create derivative works from, resell, sublicense, or use the Service to build a competing product, except where such restriction is prohibited by law.
Feedback. If you send us suggestions or feedback, we may use them without restriction, obligation, or compensation.
13. Confidentiality
Each party will protect the other's non-public information disclosed in connection with the Service with at least reasonable care, use it only to perform under these Terms, and not disclose it except to personnel and advisors bound by confidentiality. This does not apply to information that is public, independently developed, rightfully received from a third party, or required to be disclosed by law, provided reasonable notice is given where permitted.
14. Disclaimers
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
We specifically do not warrant or guarantee:
- Any number or rate of registrations, attendees, show-ups, opens, clicks, replies, meetings booked, pipeline, or revenue
- Any level of inbox placement, deliverability, or sender reputation
- That the Service will be uninterrupted, timely, secure, or error-free, or that defects will be corrected
- The accuracy, completeness, or reliability of AI output, analytics, or reporting
- The performance or continued availability of Customer Infrastructure or Third-Party Platforms
Any figures, benchmarks, case studies, or examples on our website are illustrative and not a promise of results. Outcomes depend on your offer, audience, content, list quality, and infrastructure.
Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you.
15. Indemnification
You will defend, indemnify, and hold harmless WebinarOS, Welcomes Stranger Strategies LLC, and their members, officers, employees, and agents from any claim, demand, proceeding, loss, liability, damage, fine, penalty, or expense (including reasonable attorneys' fees) arising out of or related to:
- Your Customer Data or campaign content
- Your messages, lists, consent practices, or sending activity, including any spam, CAN-SPAM, CASL, TCPA, or privacy claim
- Customer Infrastructure, including domains, servers, DNS, and reputation
- Your use of Third-Party Platforms
- Your breach of these Terms, the Acceptable Use Policy, or any law
- Your infringement or misappropriation of any third party's rights
We will notify you of the claim, give you control of the defense (no settlement admitting fault or imposing obligations on us without our consent), and cooperate at your expense.
16. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY IS LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST PIPELINE, LOST DATA, LOST GOODWILL, LOST SENDER REPUTATION, OR BUSINESS INTERRUPTION, EVEN IF ADVISED OF THE POSSIBILITY.
OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE AMOUNT YOU ACTUALLY PAID US IN THE THREE (3) MONTHS IMMEDIATELY BEFORE THE EVENT GIVING RISE TO THE CLAIM.
These limits apply to all theories of liability — contract, tort, negligence, strict liability, statute, or otherwise — and survive failure of any limited remedy. They do not limit your payment obligations, your indemnity obligations, or liability that cannot be limited by law.
You acknowledge that the fees reflect this allocation of risk and that we would not provide the Service on these prices without it.
17. Force majeure
Neither party is liable for delay or failure caused by events beyond its reasonable control, including acts of God, natural disaster, war, terrorism, civil unrest, labor disputes, government action, epidemic, internet or utility failure, cyberattack, or the failure of any third-party provider. Payment obligations are not excused.
18. Governing law and disputes
These Terms are governed by the laws of the State of Colorado, without regard to conflict-of-law rules. The UN Convention on Contracts for the International Sale of Goods does not apply.
The exclusive venue for any dispute is the state and federal courts located in Denver County, Colorado, and each party consents to personal jurisdiction there and waives any objection to venue.
Each party waives any right to a jury trial and to participate in any class, collective, or representative action.
Before filing, the parties will attempt to resolve the dispute in good faith for 30 days after written notice.
19. Changes to these Terms
We may update these Terms. The "Last updated" date reflects the current version. For material changes we will give at least 30 days' notice by email or in-product notice. Continued use after the effective date constitutes acceptance. If you do not accept, cancel before the change takes effect.
20. General
Entire agreement. These Terms, the Privacy Policy, the Acceptable Use Policy, and any order or DPA are the entire agreement and supersede all prior discussions and proposals. Any purchase order or vendor terms you issue are of no effect.
Assignment. You may not assign these Terms without our written consent, except to a successor of substantially all your business. We may assign freely.
Severability. If a provision is unenforceable, it is modified to the minimum extent necessary and the rest remains in force.
No waiver. Failure to enforce a provision is not a waiver of it.
Notices. To you at the email on your account; to us at [email protected] and the postal address above. Email notice is effective on transmission.
Independent contractors. No partnership, joint venture, agency, or employment is created.
Export and sanctions. You represent you are not located in an embargoed country or on any restricted-party list, and you will comply with all export control and sanctions laws.
Publicity. We will not use your name or logo in marketing materials without your prior written consent.
Headings. For convenience only, with no legal effect.
