Nexpand Mail — Terms of Service

Last updated: 18 July 2026 · Effective: 18 July 2026

These Terms of Service (the "Terms") govern access to and use of the Nexpand Mail web application available at mail.nexpand.hu and related services (the "Service"). The Service is operated by Zsigmond Gergely, egyéni vállalkozó (sole proprietor, Hungary), registered seat: 1026 Budapest, Guyon köz 5., Hungary, sole-proprietor registration number: 59673189, VAT number: 90477241-2-41 ("Provider", "we", "us"). Contact: gergely.zsigmond@prime4squad.com.

By creating an account, ticking the acceptance checkbox at registration, or using the Service, you agree to these Terms, the Acceptable Use & Anti-Spam Policy, the Data Processing Agreement and the Privacy Policy, which form part of these Terms. If you accept on behalf of a company, you confirm you are authorised to bind that company.

1. Business use only

The Service is a professional business tool offered exclusively to businesses, sole traders and other professional users (B2B). By registering you confirm that you use the Service in the course of your trade, business or profession and not as a consumer. Consumer-protection rules applicable to consumer contracts do not apply.

2. The Service

Nexpand Mail sends personalised business outreach email from your own mailboxes (Microsoft 365 / Outlook and Google Workspace / Gmail accounts that you connect), through the providers' official APIs, paced to configurable daily caps and send windows. It includes contact and list management, campaign and follow-up sequence tools with content variation, reply and bounce detection with automatic suppression, an optional mailbox warm-up module, per-company access roles, and an optional HubSpot synchronisation you can connect.

Emails are sent from your own mailboxes under your own name and domains. We do not provide sending infrastructure, sender reputation, email addresses or recipient lists.

3. Your mailboxes and email providers

• You may only connect mailboxes you own or are expressly authorised to operate. Connecting a mailbox may require consent from your organisation's administrator.
• Your use of Microsoft and Google services remains governed by your agreements with those providers, including their acceptable-use and bulk-email policies and technical sending limits. You are responsible for staying within them.
• OAuth tokens for connected mailboxes are stored encrypted; we never see or store your mailbox password. You can disconnect a mailbox at any time, which revokes the Service's access.
• Email providers may throttle, block or suspend mailboxes at their discretion (for example after spam complaints). You bear this risk; the Service's pacing and warm-up features reduce it but cannot eliminate it.
• The Service is not affiliated with, endorsed by or sponsored by Microsoft or Google.

4. Your responsibility for lawful emailing

You are the sender of every email dispatched through the Service. You are solely responsible for compliance with all laws applicable to your outreach — including the GDPR, the ePrivacy rules implemented in the recipient's country, Hungarian Act XLVIII of 2008 on advertising, and the US CAN-SPAM Act where applicable — and for the content of your messages. The Acceptable Use & Anti-Spam Policy sets out binding minimum rules. We may suspend sending if your use generates spam complaints, provider warnings or legal risk.

5. Account and roles

You must provide a valid email address and keep your credentials confidential. You are responsible for all activity under your account. The Service's company-based roles let a manager grant other users access to a company's senders and data; granting and revoking such access appropriately is the manager's responsibility. Notify us without undue delay of any suspected unauthorised use.

6. Free trial

New accounts receive a free trial (currently 14 days). At the end of the trial, sending is paused until a subscription is purchased; your data remains accessible. We may modify or withdraw trial offers at any time; a trial does not obligate you to purchase.

7. Fees and payment

• Paid use of the Service requires a subscription. Prices are shown at purchase inside the app; unless stated otherwise they are exclusive of VAT, which is added where applicable.
• Payments are processed by Stripe; we do not store your card details. Subscriptions renew automatically for successive billing periods until cancelled.
• You can cancel at any time on the Billing page; cancellation takes effect at the end of the current billing period. Fees already paid are non-refundable, including for partly used periods, except where required by mandatory law.
• We may change prices with at least 30 days' notice; changes apply from your next renewal.
• If a renewal payment fails, we may pause sending and, after reasonable notice, suspend the account.

8. Your data

• You own your data. Contact lists, campaign content and message data you bring into or generate through the Service ("Customer Data") remain yours. You grant us the rights needed to host, process, back up and display it solely to provide the Service.
• You are the data controller for Customer Data; we process it as your processor under the Data Processing Agreement.
• You can export your data at any time. On account closure we delete Customer Data as described in the DPA.

9. Warm-up module

The warm-up module exchanges automated emails between mailboxes in a pool you configure. You must only include mailboxes and recipients that you control or whose owners have agreed to participate. Warm-up traffic is generated content; you are responsible for the pool's composition.

10. Intellectual property

The Service and all associated software, design and branding are the Provider's property or licensed to it. Except for the rights expressly granted in these Terms, no rights are transferred to you.

11. Availability and support

We aim for high availability but the Service is provided without an uptime guarantee. Email providers change their APIs and policies without notice; features that depend on them may be temporarily unavailable, and restoring them is handled on a best-effort basis. We may change, improve or discontinue features with reasonable notice where a change is material and adverse. Support is provided on a best-effort basis by email.

12. Warranties and disclaimers

The Service is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties, express or implied. In particular, we do not warrant any deliverability, inbox placement, open, reply or conversion outcome — these depend on your domains, content, lists and the receiving systems.

13. Limitation of liability

To the maximum extent permitted by law: (a) neither party is liable for indirect or consequential damages, loss of profits, loss of business, or loss of data (beyond restoration from existing backups); (b) the Provider's total aggregate liability arising out of or related to the Service is limited to the fees you paid in the 12 months preceding the event giving rise to the claim; (c) nothing limits liability for intentional misconduct, gross negligence, or damage to life, limb or health, or any other liability that cannot be limited under Hungarian law. You acknowledge that the subscription price reflects this allocation of risk.

14. Indemnity

You will indemnify the Provider against third-party claims (including claims by email recipients, data subjects, authorities, or your email provider) arising from your Customer Data, the content or targeting of your emails, or your use of the Service in breach of these Terms or applicable law.

15. Suspension and termination

• You may stop using the Service and cancel your subscription at any time, and may request deletion of your account by email.
• We may suspend or terminate the account (with prior notice where practicable) if you materially breach these Terms or the Acceptable Use & Anti-Spam Policy, if required by law, or if your use creates security, deliverability or legal risk for the Service or other customers.
• After termination, we delete Customer Data as described in the DPA. Export your data before closing your account.

16. Changes to these Terms

We may update these Terms. For material changes we will give at least 15 days' notice by email or in-app notice. Continued use after the effective date constitutes acceptance; if you do not agree, stop using the Service and cancel before the change takes effect.

17. Governing law and disputes

These Terms are governed by Hungarian law, excluding its conflict-of-law rules and the UN CISG. The parties will first attempt to settle disputes amicably; failing that, the Hungarian courts having jurisdiction at the Provider's registered seat are exclusively competent, to the extent permitted by law.

18. Miscellaneous

If a provision of these Terms is invalid, the remainder stays in force. Our failure to enforce a provision is not a waiver. You may not assign the agreement without our consent; we may assign it to a successor of the business. These Terms, together with the documents referenced in them, are the entire agreement regarding the Service. The language of the agreement is English.
