Terms of Service

The agreement between you and Send4.ai for use of the platform.

Last updated: 14 August 2026 · Version 2026-08-14

1. Who these terms are between

These Terms of Service ("Terms") are a binding agreement between Nord it, UAB, Ateities g. 5-86, LT-08305 Vilnius, Lithuania ("Send4.ai", "we", "us") and the business or person creating an account ("you", the "Customer"). You accept them by ticking the acceptance box at registration, by continuing with Google sign-in, or by using the service. The version you accepted is recorded with your account. Send4 is a business tool — by accepting you confirm you are acting in the course of a trade, business, or profession, and that you are authorised to bind the company you register for.

2. The service

Send4 is an AI-assisted omnichannel messaging platform: it connects your messaging channels, uses AI to hold and qualify conversations with your contacts ("leads"), and gives your team a shared workspace to monitor and take over those conversations. A built-in simulator lets you try the AI without a real phone number; it does not send messages to real recipients. To reach real contacts you connect your own messaging provider account, as described in Section 4.

3. Your account

  • Provide accurate registration information and keep it up to date.
  • Keep your credentials confidential; you are responsible for activity under your account.
  • You must verify your email address before signing in with a password.
  • Notify us promptly of any unauthorised use of your account.

4. Plans and fees

Send4 is a paid service. The available plans, their prices, billing cycles, and the monthly allowance included in each are published at send4.ai/pricing and form part of these Terms. You can change your plan, and switch between monthly and annual billing, at any time — see "Renewal, changes and cancellation" below for when a change takes effect.

Free trial. New accounts begin with a fourteen (14) day trial of our mid-tier plan: its full feature set, with a trial-sized monthly allowance. You give us a payment card to start the trial, but nothing is charged during the fourteen days. We may offer a trial once per customer and may end a trial early where Section 5 is breached.

When the trial ends. Unless you cancel first, your subscription begins automatically on the fifteenth day and we charge your card for the first period on the mid-tier plan, at the price then in force — unless you have moved to a different plan or billing cycle before then, in which case we charge for that one. You can change plan during the trial from the plan page in your account. We email you before that first charge. You can also cancel at any point during the trial and pay nothing; the account then stops processing new work, your data is retained, and you can subscribe later.

Trials are provided as an evaluation. A trial is made available free of charge for you to evaluate the service. To the maximum extent permitted by law, we give no warranties in respect of trial use and accept no liability for loss arising from it — including messages sent to, or not sent to, your contacts, missed or mishandled leads, and any charges billed to you by your own messaging provider. Section 12 applies in any event.

Messaging channels and carrier costs. Team seats and messaging channels are included on every plan, subject to fair use. Messaging traffic runs on your own account with a messaging provider (for example Twilio or Vonage), which you connect to Send4. That provider bills you directly for carrier and number charges; those charges are not part of our fees and we do not mark them up.

Payment and tax. You keep a payment card on file, and we charge it in advance at the start of each billing period. We email you a receipt and an invoice for every charge, and you can change the card, or download past invoices, at any time in the billing portal in your account. Card details are entered directly with our payment processor and are not stored by us. Some customers pay us by bank transfer instead: where we have agreed in writing to invoice you — Enterprise plans, and accounts we already invoiced before card payment existed — we invoice by email in advance of the period the invoice covers and you pay within fourteen (14) days of the invoice date. Prices are stated in euro and exclude any applicable taxes. We are not currently registered for VAT, so our invoices carry no VAT. If we become VAT-registered, VAT at the applicable rate will be added to invoices from the date of registration — for business customers established elsewhere in the EU who give us a valid VAT identification number, this normally means the reverse-charge mechanism applies instead.

If a payment fails. Cards get declined and expire. If a charge fails we retry it over the following days and email you each time so you can put it right, and you can update the card yourself in the billing portal. If payment has still not succeeded seven (7) days after the first failed attempt, your subscription ends and the service stops processing new work; your data is retained, your account stays open, and you can subscribe again at any time from your account. Where we invoice you instead, the equivalent point is an invoice more than fourteen (14) days overdue, and we notify you by email before suspending the service.

Usage limits are a stop, not a surcharge. Each plan includes a monthly allowance as published on the pricing page. When you reach it, AI processing pauses for the remainder of that calendar month and resumes when the allowance resets; we aim to warn you by email before you get there. We do not bill you for exceeding an allowance — there are no overage charges. Upgrading raises the limit immediately.

Renewal, changes and cancellation. Subscriptions renew automatically for a further period of the same length, and we charge the card on file, unless you cancel before the current period ends. You can cancel yourself at any time in the billing portal in your account — or ask us at [email protected] and we will do it for you — and the service stays available until the end of the period you have paid for. Upgrades take effect immediately and we charge the difference for the rest of the current period pro rata; downgrades take effect at the start of the next period.

Refunds.

  • Trial — nothing is charged, so there is nothing to refund.
  • Monthly plans — cancel at any time; the month already paid for is not refunded and the service runs to the end of it.
  • Annual plans — if you cancel within thirty (30) days of the start of an annual period, we refund the unused whole months of that period. After those thirty days the period already paid for is not refunded.

Refunds are returned to the payment card that made the payment, or, where we invoiced you, by bank transfer. This does not affect any refund you are entitled to under mandatory law, or a refund we owe you because we failed to provide the service.

Price changes. We may change prices and the contents of plans for future billing periods, with at least thirty (30) days' notice by email. A period you have already paid for is not repriced. If you do not accept a change, cancel before the period it would first apply to begins.

5. Acceptable use — messaging compliance is your responsibility

You instruct Send4 to contact your leads. You are solely responsible for making sure you may lawfully do so. In particular you must:

  • Have a lawful basis (such as consent where required) to message every contact you upload or connect, under the laws that apply to you and them — including the GDPR and ePrivacy rules in the EU and equivalents elsewhere;
  • Honour opt-outs and stop requests immediately;
  • Not send spam, unsolicited bulk messages, or deceptive, fraudulent, or unlawful content;
  • Not upload data you have no right to process, and no special-category (sensitive) data unless you have a valid legal basis;
  • Not use the service to harass, defame, or harm anyone, to violate telecommunications carrier rules, or to attempt to breach or overload the platform;
  • Not resell or provide the service to third parties except to your own organisation, and not reverse-engineer it.

Messaging the United States. If you message US phone numbers, you represent and warrant that you have prior express written consent from each recipient as required by the Telephone Consumer Protection Act (TCPA), that you can produce evidence of that consent on request, that you send no marketing message outside the hours of 8am–9pm in the recipient's local time, that you comply with the CTIA Messaging Principles, and that your sending brand and campaign are properly registered for A2P 10DLC where required by the carriers. TCPA damages are statutory and per-message; this is your risk, not ours.

Messaging the United Kingdom. If you message UK phone numbers, you represent and warrant that you comply with the Privacy and Electronic Communications Regulations (PECR), including the consent requirement in regulation 22, and with the UK GDPR.

Opt-outs are your responsibility. Every message campaign you run must give recipients a working way to stop receiving messages, and you must honour a stop request immediately and permanently — including where it arrives in words rather than a keyword. Do not assume the platform detects opt-outs on your behalf: you are responsible for monitoring your conversations and suppressing contacts who have asked you to stop. Where you collect consent, tell recipients who is messaging them, roughly how often, that message and data rates may apply, and how to stop and how to get help.

We may suspend or restrict accounts that we reasonably believe violate this section, harm the platform, or expose us or carriers to liability — where practicable we will notify you and give you a chance to remedy the issue first.

6. Your data, our processing

You own your data. Lead and conversation data you process through Send4 remains yours; we process it only as your processor, on your instructions, as described in our Privacy Policy and our data processing agreement (available on request at [email protected]). The sub-processors we engage, with each provider's purpose, location, and transfer safeguard, are listed at send4.ai/subprocessors; that list forms part of that agreement. We update it before engaging a new sub-processor that handles customer personal data, and customers with a data processing agreement are notified with 30 days to object as set out in that agreement. You grant us the non-exclusive right to host, process, and transmit your data as needed to provide the service.

7. AI-generated content

The service generates message content with large language models. AI output can be inaccurate, incomplete, or inappropriate for your context. You are responsible for configuring your scenarios, reviewing AI behaviour, and supervising conversations — especially in regulated industries. We do not warrant that AI-generated messages are correct or fit for any particular purpose.

8. Intellectual property

We own the platform, its software, and everything we make available to you except your data. These Terms grant you a limited, non-exclusive, non-transferable right to use the service for your internal business purposes while your account is active. Feedback you give us may be used to improve the service without obligation to you.

9. Third-party services

Message delivery depends on third parties (telecom carriers, messaging providers, email providers) we do not control. We are not responsible for their availability, delivery success, or fees they charge you directly. Google sign-in is subject to Google's own terms.

10. Availability

We aim for high availability but provide the service — and trial accounts in particular — "as is" and without an uptime guarantee. We may modify features or perform maintenance with reasonable notice.

11. Termination

You may stop using the service and close your account at any time by contacting [email protected]. We may terminate or suspend your account for material breach of these Terms (including Section 5), for legal reasons, for non-payment as set out in Section 4, or after twelve (12) months of inactivity on an account with no active subscription, in which case we will give you at least 30 days' notice by email first. After closure we handle your data as described in the Privacy Policy — including erasing it on request — and you can ask us for an export of your data before closing the account.

12. Warranties and liability

To the maximum extent permitted by law: the service is provided without warranties of any kind, express or implied; we are not liable for indirect or consequential damages, loss of profits, or loss of data; and our total aggregate liability under these Terms is limited to the greater of (a) the fees you paid us in the six (6) months before the event giving rise to the claim, or (b) EUR 100. Nothing in these Terms excludes liability that cannot be excluded by law, including for intent or gross negligence.

13. Indemnity

You will indemnify us against third-party claims, fines, and reasonable costs arising from your breach of Section 5 (acceptable use and messaging compliance) or from data you process through the service without a lawful basis. This expressly includes claims under the TCPA, the CTIA Messaging Principles, PECR, the GDPR and the UK GDPR, and any carrier penalty or filtering imposed because of your traffic.

14. Changes to these terms

We may update these Terms. For material changes we will give account holders at least 30 days' notice by email or in the app. If you continue using the service after the effective date, the new version applies; if you object, you may close your account before it takes effect. Each version is dated and numbered at the top of this page.

15. Governing law and disputes

These Terms are governed by the laws of the Republic of Lithuania, and the courts of Vilnius, Lithuania have exclusive jurisdiction, without prejudice to mandatory consumer or data protection law that applies regardless. The English version of these Terms is the binding version.
