Master Service Agreement

Version 1.0, effective 28 August 2026

This Master Service Agreement (the Agreement) is between Meridian Interface Ltd, a company registered in England and Wales (Company No. 16150489) whose registered office is at Park House, Wilmington Street, Leeds, LS7 2BP, trading as Mailbox Fleet (Mailbox Fleet, we, us), and the business identified in the signature block or the account application (the Customer, you).

It incorporates the Terms of Service, the Sending Policy, the Acceptable Use Policy (AUP), the Data Processing Agreement (DPA) and the Privacy Policy. If those documents conflict, the order of precedence is: the DPA (for personal data only), then this Agreement, then the AUP, then the Sending Policy, then the Terms of Service.

1. Definitions

1.1 Customer means the business entity holding a subscription to the Service, as defined in the Terms of Service. The Customer must be acting in the course of business; we do not contract with consumers.

1.2 Service means the managed cold-email sending infrastructure described in clause 2, including the customer portal (the Portal).

1.3 Fleet means the set of Domains, Mailboxes and Sending IPs provisioned for the Customer, or for one End Client where clause 8 applies.

1.4 Domain means a lookalike domain name we register on the Customer's behalf under clause 9.

1.5 Mailbox means an email account hosted on our mail servers, tied to a Domain, from which the Customer's Sending Tool sends.

1.6 Sending IP means the IP address allocated to the Customer's Fleet. Each Customer (or End Client) has its own Sending IP, not shared with any other Customer.

1.7 Sending Tool means the sequencing software the Customer connects to its Mailboxes, such as Instantly, Smartlead or the Customer's own software.

1.8 Ramp means the automated volume schedule described in clause 2.4, and Cap means the per-Mailbox daily sending limit set by the Ramp and enforced at our servers.

1.9 Suppression List means the list of addresses our sending systems refuse to send to, described in section 6 of the Privacy Policy.

1.10 Verification means the identity, sanctions and business checks in clause 3.2.

1.11 Order means an order placed through the Portal or an Order Form (as defined in the Terms of Service) stating the number of Mailboxes and Domains.

1.12 End Client means a client of the Customer for whom the Customer operates a Fleet under clause 8.

1.13 Fees means the charges in clause 5.

2. The Service

2.1 We provision and operate sending infrastructure. You supply the recipients, the copy and the Sending Tool. The Service comprises:

(a) sourcing and registering Domains in your name at a flat £10 per Domain per year; (b) creating Mailboxes on our mail servers on a dedicated Sending IP; (c) configuring DNS for each Domain, including SPF, DKIM and DMARC records and tracking records; (d) the Ramp, with Caps enforced at the server; (e) inbox-placement testing during and after the Ramp; (f) monitoring every Domain and Sending IP against public blacklists and mailbox-provider reputation signals; (g) automatic pausing of a Domain that trips a reputation, complaint or spam-trap threshold, and provisioning of a warmed replacement Domain (a Swap); (h) the Suppression List; and (i) the Portal, showing your Fleet's state and delivery telemetry.

2.2 We hand over Mailbox credentials for you to connect to your Sending Tool. We do not operate your Sending Tool, write your copy or select your recipients, and we do not read message bodies (section 7 of the Privacy Policy).

2.3 The Service does not include prospect data, copywriting or campaign management, and we do not provide mailboxes on your primary business domain; all cold volume is sent from Domains.

2.4 The Ramp. Every Mailbox starts on a low Cap. We raise the Cap step by step, never by more than 20% in a day, and only while bounce rates, complaint rates and measured inbox placement stay within the thresholds in the AUP. A Domain is cleared for full volume once it holds 90% or better measured inbox placement across three consecutive placement checks, which typically takes two to three weeks. The Ramp cannot be skipped or overridden at your request, and Caps stay enforced after it completes.

2.5 Swaps. When a Domain is paused under clause 2.1(g), we may register a replacement Domain in your name, charged at the Domain fee in clause 5.2, and add it to your Fleet. A paused Domain remains yours.

3. Ordering and Verification

3.1 Orders are placed through the Portal and accepted when we confirm them there or by email.

3.2 Verification before provisioning. We provision nothing until the account has passed:

(a) an identity check of the individual opening the account, run by Stripe Identity or by manual verification with our team (section 4.1 of the Privacy Policy explains both routes and your right to choose the manual one); (b) a check of the Customer against the UK Government consolidated list of financial sanctions targets, repeated periodically; and (c) a check that the Customer is active on Companies House (or its home-country equivalent) and that the verified individual is genuinely connected to it.

3.3 You must give accurate and complete information for Verification and keep it up to date. False Verification information or a sanctions match is grounds for immediate termination under clause 7.3.

4. Accounts and access

The account, credential and security rules in section 2 of the Terms of Service apply. Mailbox credentials are for use in your Sending Tool only and must not be shared beyond your staff, contractors and End Clients.

5. Fees, billing and payment

5.1 Mailbox Fees. Mailboxes are charged monthly in advance at £2.50 per Mailbox per month for the first 199 Mailboxes on the account, and £2.00 per Mailbox per month for the 200th Mailbox and each Mailbox above it, counted across all the Customer's Fleets.

5.2 Domain Fees. Domains are charged at a flat £10 per Domain per year, payable on registration and on each anniversary while the Domain remains in your Fleet. This covers registration, renewal, DNS hosting and registrar charges.

5.3 There is no set-up fee, no minimum term and no exit fee.

5.4 Billing. We bill by card or direct debit through Stripe on the same day each month. Mailboxes added mid-period are charged pro rata for the remainder of that period. Mailboxes removed mid-period are not refunded for that period.

5.5 VAT and taxes. All Fees are exclusive of VAT and any other applicable taxes, which are added at the prevailing rate.

5.6 Late payment. If a payment fails or is not made within 14 days of its due date, we may suspend the Fleet under clause 6.1(d), charge interest and the fixed sum provided by the Late Payment of Commercial Debts (Interest) Act 1998, and allow Domains falling due for renewal to lapse.

5.7 Price changes. We may change the Mailbox or Domain Fees on at least 30 days' written notice. If you do not accept a change, cancel under clause 7.2 before it takes effect.

6. Suspension

6.1 We may suspend some or all of a Fleet, pause a Domain or Mailbox, or lower a Cap, immediately and without prior notice, where:

(a) deliverability harm: sending from the Fleet threatens the reputation of the Sending IP, our mail servers, our address ranges or other Customers, including where bounce or complaint rates exceed the thresholds in the AUP; (b) complaints: we receive an abuse report, a spam-trap hit, a mailbox-provider notice or a complaint from a recipient about the Fleet; (c) blacklisting: a Domain, the Sending IP or our range appears on a blacklist or is throttled by a mailbox provider; (d) non-payment: Fees are overdue under clause 5.6; (e) we reasonably suspect a breach of the AUP, the Sending Policy or clause 10; or (f) a court, regulator, registrar or law-enforcement body requires it.

6.2 We tell you the reason as soon as reasonably practicable and lift the suspension once the cause is resolved. Automatic pauses and Swaps under clause 2.1(g) are part of the Service, not suspensions.

6.3 Fees continue to accrue during a suspension caused by your act or omission; for suspensions caused by us we credit Mailbox Fees for the Mailboxes and days affected.

7. Term and termination

7.1 This Agreement starts when you accept it and continues until terminated.

7.2 Cancellation by you. You may cancel any Mailboxes, or the whole Agreement, at any time through the Portal or by written notice. Cancellation takes effect at the end of the current monthly billing period; we do not refund the remainder of a period already paid.

7.3 Termination by us for cause. We may terminate immediately by written notice if you: materially breach this Agreement, the AUP or the Sending Policy and (where the breach is capable of remedy) fail to remedy it within 7 days of notice; deliberately breach the AUP; provide false Verification information or fail a sanctions re-screen; fail to pay Fees within 30 days of the due date; or become insolvent or cease trading.

7.4 Termination by us for convenience. We may terminate this Agreement or any Fleet on at least 30 days' written notice.

7.5 Consequences. On termination: your access to the Portal and Mailboxes ends at the effective date; Mailbox contents are deleted 30 days later; Domains are dealt with under clause 9.4; the DPA governs the return and deletion of personal data; and clauses 5 (for accrued Fees), 9.4, 11, 12, 13, 14, 16 and 18 survive.

8. Agencies and End Clients

8.1 You may not resell, sublicense or white-label the Service without our prior written consent, except as this clause allows.

8.2 If you are an agency running outreach for clients, you may operate a separate Fleet for each End Client provided that you: identify each End Client to us by legal name and registered number before the Fleet is provisioned; obtain the End Client's authority for Domains to be registered in the End Client's name under clause 9; and remain fully responsible to us for the End Client's sending.

8.3 Each End Client Fleet has its own Sending IP, DKIM keys and Domains. We may require the End Client to pass the sanctions and business checks in clause 3.2 and may decline to provision a Fleet for any End Client.

8.4 Nothing in this clause creates a contract between us and an End Client.

9. Domain ownership and transfer-out

9.1 Domains are registered through our registrar in the Customer's name (or the End Client's name under clause 8.2) as registrant. You own each Domain from the moment of registration. We are listed as technical contact so that we can manage DNS and renewals.

9.2 While a Domain is in your Fleet you authorise us to manage its DNS, renew it, lock and unlock it, and pause it under clause 2.1(g). You must not change its nameservers or DNS records yourself while it remains in service.

9.3 You warrant that no Domain registered at your request or kept with your approval infringes anyone's trade mark or other rights, and you indemnify us against any claim that it does. Lookalike Domains are adjacent to your own brand, not anyone else's.

9.4 Transfer-out. At any time, and in any event on termination, you may ask us to transfer any Domain to a registrar account of your choosing. Within 10 business days of your request we unlock the Domain and provide the authorisation code. There is no transfer fee. If you give no transfer instructions within 60 days after termination, we may let the Domain lapse at its next renewal; we never use or resell it ourselves.

10. Customer obligations

10.1 You must use the Service only for lawful business-to-business outreach in accordance with the AUP and the Sending Policy.

10.2 You are the sender and the controller of your prospect data. You are solely responsible for complying with the UK GDPR, the Data Protection Act 2018 and the Privacy and Electronic Communications Regulations 2003 (PECR), and with the equivalent laws of every jurisdiction in which your recipients are located, including documenting a lawful basis for every message.

10.3 You must operate the Mailboxes only through a Sending Tool that respects the Caps and required unsubscribe headers, and must not attempt to bypass or defeat the Ramp, the Caps or the Suppression List.

10.4 You must keep your Verification, contact and billing details current, and respond within 2 business days to any abuse report we pass to you.

10.5 You are responsible for everything sent from your Mailboxes, whether by you, your staff, your contractors, your End Clients or anyone who obtains your credentials.

11. No deliverability guarantee

11.1 We operate the Service to achieve good inbox placement and we measure it, but placement also depends on your recipients, your copy, your Sending Tool and mailbox providers' filters, none of which we control.

11.2 The Ramp, the placement gate in clause 2.4, blacklist monitoring, Swaps and Caps are controls we operate. They are not warranties. A Domain passing the placement gate met the threshold at the time of the checks; that is not a promise that any later message will reach an inbox, that your reply rate will meet any level, or that any Domain or Sending IP will avoid a blacklist.

11.3 Except as expressly stated in this Agreement, the Service is provided with reasonable skill and care but otherwise "as is", and all other warranties, conditions and terms implied by law are excluded to the fullest extent permitted.

12. Limitation of liability

12.1 Nothing in this Agreement limits or excludes liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot lawfully be limited.

12.2 Subject to clause 12.1, neither party is liable to the other for any indirect or consequential loss, loss of profit, loss of business or revenue, loss of anticipated savings, loss of or damage to reputation or goodwill, or regulatory fines and penalties, however arising.

12.3 Subject to clauses 12.1 and 12.2, our total aggregate liability under or in connection with this Agreement, however arising, is limited to the total Fees paid by you in the 12 months immediately before the event giving rise to the claim.

12.4 Clauses 12.2 and 12.3 do not limit your obligation to pay Fees or your liability under clause 13.

13. Indemnity

13.1 You indemnify us against all losses, costs, claims, regulatory fines and expenses (including reasonable legal fees) arising out of: any message sent from your Mailboxes that breaches the AUP, the Sending Policy, PECR, the UK GDPR or any other applicable law; any claim by a recipient, mailbox provider, blacklist operator or regulator relating to your sending; any claim under clause 9.3; or any false Verification information.

13.2 We will notify you promptly of any claim and give reasonable assistance at your cost.

14. Confidentiality

14.1 Each party must keep confidential the other's non-public information obtained under this Agreement (including Fees, credentials, Fleet configuration, telemetry and End Client identities) and use it only to perform this Agreement.

14.2 This does not apply to information that is public through no fault of the recipient, already lawfully known to it, required to be disclosed by law, or shared under clause 4.5 of the AUP.

15. Data protection

15.1 The DPA applies to all personal data we process on your behalf and forms part of this Agreement. Where we act as controller (Verification, billing, the Suppression List and telemetry) the Privacy Policy describes our processing.

15.2 The Suppression List is append-only. You cannot delete entries from it, and we will not delete entries at your request, because opt-outs must be honoured permanently (section 6 of the Privacy Policy).

16. Governing law and jurisdiction

This Agreement and any dispute or claim arising out of or in connection with it (including non-contractual disputes or claims) are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction.

17. Notices

17.1 Notices to us go by email to hello@peachdata.co.uk (data-protection notices copied to privacy@peachdata.co.uk) or by post to our registered office. Notices to you go to the account owner's email address in the Portal.

17.2 Email notices are deemed received the next business day; posted notices two business days after posting. Routine operational messages may be given through the Portal alone.

18. General

18.1 Entire agreement. This Agreement, with the documents it incorporates, is the entire agreement about the Service and supersedes all earlier discussions and representations.

18.2 Changes. We may update this Agreement, the AUP, the DPA and the Sending Policy. Material changes are notified to the account owner at least 30 days before they take effect, and the Portal will ask you to review and accept them, as section 13 of the Terms of Service describes. Continued use after the effective date is acceptance.

18.3 Assignment. You may not assign this Agreement without our written consent. We may assign it to a successor of our business on notice to you.

18.4 Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control, including mailbox-provider policy changes, registrar or hosting outages and blacklist operators' decisions.

18.5 Severance, waiver and third parties. If any clause is unenforceable the rest stands; delay in enforcing a right is not a waiver; and no third party may enforce this Agreement under the Contracts (Rights of Third Parties) Act 1999.

19. Version and effective date

This is version 1.0 of the Master Service Agreement, effective 28 August 2026. The current version is always available in the Portal.
