Where Reseller’s End Customer is established outside the United Kingdom, the European Union, the European Economic Area, and Switzerland, the applicable Master License Agreement shall be the SELv2 Agreement (World) issued by Stalwart Labs LLC, available at https://stalw.art/legal/license-world.

1.6. “Confidential Information” refers to any non-public information disclosed by either Party to the other in connection with this Agreement, whether in written, oral, electronic, or other form, that is designated as confidential or that a reasonable person would understand to be confidential given the nature of the information and circumstances of disclosure.

2. APPOINTMENT

2.1. Stalwart hereby appoints Reseller as a non-exclusive reseller of subscriptions to the Products, subject to the terms and conditions of this Agreement. Reseller accepts such appointment and agrees to use commercially reasonable efforts to promote and sell the Products.

2.2. This Agreement does not grant Reseller any exclusive rights to sell the Products in any territory or market segment. Reseller may sell the Products globally without territorial restriction, but Stalwart reserves the right to sell the Products directly and to appoint additional resellers without limitation.

2.3. Exclusivity for a specific territory or market segment may be considered and mutually agreed upon in a separate written amendment based on Reseller’s demonstrated sales performance.

3. PRODUCT LICENCE AND END CUSTOMER TERMS

3.1. The Products are licensed by Stalwart on an annual subscription basis. The current pricing is published at: https://stalw.art/pricing. Stalwart reserves the right to update pricing at any time; however, pricing changes will not apply to active subscriptions already purchased by Reseller until their renewal date.

3.2. Reseller shall ensure that each End Customer accepts the Master License Agreement prior to or upon delivery of the Products. Reseller shall not deliver License Keys, grant access to the Products, or provision any End Customer account until the End Customer has agreed to the Master License Agreement. Reseller is responsible for maintaining records evidencing each End Customer’s acceptance.

3.3. Reseller shall not modify, amend, or waive any terms of the Master License Agreement on behalf of Stalwart. Any End Customer requesting modifications to the Master License Agreement must be referred to Stalwart for direct negotiation.

3.4. Upon non-renewal or expiration of an End Customer’s subscription, all Enterprise features will be disabled and the software will revert to the Community Edition, in accordance with the Master License Agreement.

4. RESELLER DISCOUNTS

4.1. Stalwart shall provide Reseller with the following discount tiers on the published subscription prices, determined by the support model selected for each End Customer engagement:

Standard Reseller Discount (10%): Applies where Reseller sells the Products and Stalwart provides all end-user support (Tier-1 and Tier-2) directly to the End Customer. Under this model, Reseller’s role is limited to sales, billing, and account management.

Support Reseller Discount (20%): Applies where Reseller provides Tier-1 Support directly to its End Customers, and Stalwart provides only Tier-2 Support for escalated issues. To qualify for this discount tier, Reseller must demonstrate the capability and resources to deliver Tier-1 Support in a timely and professional manner.

4.2. The applicable discount tier shall be determined on a per-End-Customer basis and may differ across Reseller’s customer portfolio. Reseller shall indicate the selected support model when placing each order.

4.3. Reseller is free to set its own retail pricing to End Customers. The discounts set forth in this Section represent the reduction applied to Stalwart’s published prices when invoicing Reseller, and do not restrict or dictate Reseller’s retail pricing.

5. SUPPORT RESPONSIBILITIES

5.1. Where Reseller provides Tier-1 Support (20% discount model):

(a) Reseller shall serve as the first point of contact for all End Customer support inquiries and shall use commercially reasonable efforts to resolve Tier-1 issues in a timely manner.

(b) Reseller shall only escalate issues to Stalwart after performing reasonable diagnostic analysis and determining that the issue requires Tier-2 Support (code-level investigation, bug confirmation, or patch development).

(c) Escalations to Stalwart shall include a detailed description of the issue, steps taken to diagnose, relevant logs or configuration details, and the End Customer’s environment information.

(d) Stalwart shall use commercially reasonable efforts to respond to properly escalated Tier-2 issues within a timeframe consistent with the severity of the issue.

5.2. Where Stalwart provides all support (10% discount model):

(a) Stalwart shall provide Tier-1 and Tier-2 support directly to the End Customer, subject to the support terms set forth in the Master License Agreement (including the 150-Mailbox threshold for priority email support).

(b) Reseller shall facilitate communication between Stalwart and the End Customer as reasonably necessary and shall not interfere with Stalwart’s support processes.

5.3. Regardless of the support model, Stalwart retains sole responsibility for the release of software updates, patches, and new versions.

6. ORDERING, PAYMENT, AND INVOICING

6.1. All orders placed by Reseller must be in writing or submitted through a mutually agreed upon ordering system. Each order shall specify the End Customer name, licensed domain, Mailbox count, subscription term, and the applicable support model (10% or 20% discount tier).

6.2. Upon acceptance of an order, Stalwart will issue the appropriate License Keys and provisioning instructions to Reseller for onward delivery to the End Customer, or directly to the End Customer if mutually agreed.

6.3. Reseller is responsible for collecting all payments from End Customers. Reseller shall remit payment to Stalwart, net of the applicable discount, within thirty (30) days of the date of Stalwart’s invoice (“Net-30”).

6.4. All prices and invoices are denominated in Euros (EUR). Reseller may request to pay in pounds sterling (GBP) or United States Dollars (USD) at the prevailing exchange rate as mutually agreed at the time of invoicing.

6.5. All amounts payable under this Agreement are exclusive of Value Added Tax (VAT) and any other applicable indirect taxes, which shall be added to invoices where required by law and paid by Reseller. Where the reverse-charge mechanism applies under Article 196 of Council Directive 2006/112/EC (or its successor) or under the equivalent provisions of UK VAT law, the invoice shall be issued without VAT and Reseller shall account for VAT in its own jurisdiction.

6.6. Late payments shall, without prejudice to any other right or remedy, accrue interest in accordance with the Late Payment of Commercial Debts (Interest) Act 1998 (or such equivalent statutory regime as applies to Reseller). Reseller shall also be liable for the reasonable costs of recovery in accordance with that Act.

6.7. In the event Reseller fails to collect payment from an End Customer, Reseller remains fully responsible for payment to Stalwart. Non-payment by an End Customer does not relieve Reseller of its payment obligations under this Agreement.

7. INTELLECTUAL PROPERTY AND BRANDING

7.1. All rights, title, and interest in and to the Products, including all intellectual property rights, are and shall remain the exclusive property of Stalwart and its licensors. Nothing in this Agreement grants Reseller any ownership interest in the Products or any associated intellectual property.

7.2. Reseller shall not alter, obscure, or remove any copyright, trademark, or proprietary rights notices incorporated in the Products.

7.3. Stalwart hereby grants Reseller a non-exclusive, non-transferable, revocable licence to use the Stalwart Marks solely in connection with the marketing, promotion, and resale of the Products during the term of this Agreement. The Stalwart Marks are registered trademarks of Stalwart Labs Ltd in the United Kingdom and the European Union, and of Stalwart Labs LLC in the United States.

7.4. Reseller shall use the Stalwart Marks in accordance with the following guidelines:

(a) The Stalwart Marks shall be displayed accurately and without modification, distortion, or alteration of colour, proportion, or design.

(b) Reseller shall not use the Stalwart Marks in any manner that implies a partnership, joint venture, endorsement, or affiliation beyond the reseller relationship established by this Agreement.

(d) Stalwart may provide brand guidelines and assets from time to time. Reseller shall comply with any such guidelines upon receipt.

7.5. Upon termination of this Agreement, Reseller shall immediately cease all use of the Stalwart Marks and remove them from all marketing materials, websites, and other media within thirty (30) days.

8.4. Each Party shall implement and maintain technical and organisational measures appropriate to the risk pursuant to Article 32 of the UK GDPR and the EU GDPR, and shall notify the other Party of any confirmed personal data breach affecting personal data processed under this Agreement without undue delay and in any event within seventy-two (72) hours of becoming aware of the breach.
