Effective date: July 30, 2026 — Last updated: July 30, 2026
These Terms of Service (“Terms”) form a binding agreement between [Legal Entity Name], operating as SenderRank (“SenderRank,” “we,” “us,” or “our”), and the person or entity using our website and application (“you” or “Customer”). By creating an account or otherwise using senderrank.com, app.senderrank.com, or any related service (collectively, the “Service”), you agree to these Terms. If you do not agree, do not use the Service.
If you are using the Service on behalf of a company or other entity, you represent that you have authority to bind that entity, and “you” refers to that entity.
1. The Service
SenderRank is a deliverability intelligence platform built exclusively for Klaviyo customers. The Service monitors sender reputation, authentication (SPF/DKIM/DMARC), sending infrastructure, campaign performance, and subscriber engagement, and combines these signals into an SR Score and related reports, alerts, and recommendations. SenderRank currently supports Klaviyo as the only email service provider integration; other ESPs are not supported.
SenderRank is a monitoring and advisory tool. Except for the narrow “click-to-fix” feature described in Section 5, SenderRank does not make changes to your email infrastructure, ESP settings, or DNS configuration on your behalf.
2. Eligibility and Accounts
The Service is intended for business use by individuals at least 18 years old, acting on behalf of a business. You must provide accurate registration information and keep it up to date. You are responsible for maintaining the confidentiality of your login credentials and for all activity under your account. Notify us promptly at security@senderrank.com if you suspect unauthorized access.
3. Connecting Third-Party Accounts
To use the Service, you will connect one or more third-party accounts, which may include your Klaviyo account (via OAuth), Google Postmaster Tools, and, optionally, a DNS provider (Cloudflare, GoDaddy, or Porkbun).
By connecting any third-party account, you represent and warrant that:
- You own, or have full authority to connect and grant SenderRank access to, the domain(s), Klaviyo account, and DNS provider account(s) in question;
- Connecting these accounts to SenderRank does not violate any agreement you have with that third party or with any other person or entity (including, for agencies, your obligations to your own clients); and
- You will promptly disconnect any account you are no longer authorized to access.
SenderRank is not responsible for the availability, accuracy, or continued operation of any third-party service (including Klaviyo, Google, Stripe, or any DNS registrar). Changes those providers make to their APIs, data, or policies may affect the Service, and SenderRank will make commercially reasonable efforts to adapt but does not guarantee uninterrupted compatibility.
4. Agencies and Client Domains
If you are an agency using SenderRank to manage domains on behalf of clients, you are solely responsible for obtaining all necessary authorization from each client before connecting that client’s Klaviyo, Postmaster, or DNS provider accounts, and for your own agreement with that client governing your handling of their data. SenderRank acts as described in our Privacy Policy’s “Data Processing Roles” section.
5. Click-to-Fix DNS Changes
For domains where you have connected a supported DNS provider, SenderRank may identify specific DNS issues (such as a missing or misconfigured SPF or DMARC record) and offer a “Fix it” action. The following rules govern this feature at all times:
- No DNS record is ever written without your specific, logged click on a “Fix it” action. No background job, cron process, or automated workflow writes DNS records on your behalf, even after you connect a registrar.
- MX records are never written by SenderRank, under any circumstance.
- DKIM records are never written or rotated by SenderRank, except for the narrow case of Klaviyo static-mode domain-verification records (CNAME and TXT records using the exact values returned by Klaviyo’s own API), and even then only via your logged “Fix it” click.
- SPF and DMARC changes are click-to-fix only, with one narrow, explicitly scoped exception: SenderRank may automatically advance a DMARC policy’s enforcement percentage (“pct” value) on a domain that already has an established quarantine-or-stronger policy, as part of a documented, gradual rollout you have configured.
- You are solely responsible for reviewing the proposed change before clicking “Fix it.” DNS changes can affect mail flow, website availability, and other services connected to your domain. SenderRank is not liable for any consequence of a DNS change you authorized by clicking “Fix it,” including misconfiguration, downtime, or loss of mail.
6. Subscriptions, Trials, Fees, and Billing
The Service is offered on Lite, Standard, and Pro subscription plans, each with different monthly prices and domain limits, as described on our pricing page. New customers may access a discounted 30-day trial of full Pro-tier functionality, after which the subscription converts to a regular paid plan at the then-current rate unless cancelled beforehand.
- Subscriptions are billed in advance on a recurring monthly basis via Stripe and automatically renew until cancelled.
- You may cancel at any time from your account settings; cancellation takes effect at the end of the current billing period, and we do not provide prorated refunds for partial periods except where required by law.
- You are responsible for all applicable taxes, and fees are exclusive of tax unless stated otherwise.
- We may change our prices with reasonable advance notice; continued use of the Service after a price change takes effect constitutes acceptance of the new price.
- We may suspend or downgrade your account if payment fails and is not remedied after reasonable notice.
7. Domain Limits and Fair Use
Each plan permits monitoring a limited number of domains as described on our pricing page. You may not use multiple accounts, or misrepresent domain ownership, to circumvent these limits. We reserve the right to review usage that appears to abuse domain limits, API quotas, or the click-to-fix feature.
8. Referral and Agency Partner Programs
We offer a customer referral program (automatic enrollment, commission on referred subscriptions for a limited period) and an agency partner program (application-based, recurring commission, directory listing, and client account access). Participation in either program is subject to the specific program terms made available at enrollment or application, which are incorporated into these Terms by reference. We may modify, suspend, or terminate either program, or your participation in it, at our discretion, including for suspected fraud or abuse.
9. Acceptable Use
You agree not to:
- Use the Service to monitor, scan, or connect any domain, Klaviyo account, or DNS provider account you are not authorized to access;
- Use the Service for any unlawful purpose, including to facilitate spam, phishing, or malware distribution;
- Attempt to reverse engineer, decompile, or access the source code of the Service, except as permitted by law;
- Scrape, resell, sublicense, or white-label the Service without our prior written consent;
- Interfere with or disrupt the integrity or performance of the Service, including through excessive automated requests;
- Circumvent plan-based domain, feature, or usage limits;
- Misrepresent your identity or affiliation, or impersonate any person or entity.
We may suspend or terminate accounts that violate this Section, with or without notice, at our discretion.
10. Intellectual Property
SenderRank and its licensors own all right, title, and interest in the Service, including its software, scoring methodology, benchmarks, designs, and trademarks (collectively, “SenderRank IP”). Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your internal business purposes during your subscription. No other rights are granted. You may not use SenderRank trademarks or the “SenderRank” name without our prior written permission, except as expressly permitted (for example, the “Powered by SenderRank” attribution link, where applicable).
11. Your Data
As between you and SenderRank, you retain all rights to the data from your connected Klaviyo, Postmaster, and DNS accounts (“Customer Data”). You grant SenderRank a limited license to access, process, and use Customer Data solely to provide, maintain, and improve the Service, including to compute aggregate, de-identified benchmarks as described in our Privacy Policy. We do not sell Customer Data. If you provide feedback or suggestions about the Service, you agree we may use them without restriction or compensation to you.
12. Confidentiality
Each party agrees to protect the other’s non-public business, technical, and account information disclosed in connection with the Service using at least the same degree of care it uses for its own confidential information of similar nature, and not to disclose it except to employees, contractors, or subprocessors who need it to perform under these Terms, or as required by law.
13. No Guarantee of Deliverability Outcomes
Email deliverability depends on many factors outside SenderRank’s control, including decisions made by mailbox providers (such as Gmail, Outlook, and Yahoo), your own sending practices, your Klaviyo configuration, and third-party blocklists. SenderRank provides monitoring, scoring, and recommendations to help you understand and improve your sending reputation, but does not guarantee any specific inbox placement rate, deliverability outcome, SR Score, or improvement in engagement or sender reputation.
14. Privacy
Our Privacy Policy, available at senderrank.com/privacy-policy, describes how we collect, use, and share information in connection with the Service and is incorporated into these Terms. By using the Service, you agree to the practices described there.
15. Term and Termination
These Terms remain in effect while you use the Service. You may terminate by cancelling your subscription and closing your account. We may suspend or terminate your access, with notice where reasonably practicable, if you materially breach these Terms, fail to pay fees when due, or if we reasonably believe your use of the Service poses a security, legal, or reputational risk to SenderRank or others. Upon termination, your right to use the Service ends immediately; Sections 10 through 20 of these Terms survive termination.
16. Disclaimer of Warranties
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, THAT ANY DATA FROM THIRD-PARTY INTEGRATIONS WILL BE ACCURATE OR COMPLETE, OR THAT ANY RECOMMENDATION OR SCORE WILL ACHIEVE ANY PARTICULAR RESULT.
17. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, SENDERRANK AND ITS OFFICERS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF THE SERVICE, INCLUDING ANY DNS CHANGE MADE THROUGH THE CLICK-TO-FIX FEATURE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. SENDERRANK’S TOTAL LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE AMOUNT YOU PAID TO SENDERRANK IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS OF LIABILITY, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU.
18. Indemnification
You agree to defend, indemnify, and hold harmless SenderRank and its officers, employees, and agents from any claim, liability, damage, or expense (including reasonable attorneys’ fees) arising from: (a) your use of the Service; (b) your breach of these Terms, including the representations in Sections 3 and 4 regarding your authority to connect third-party accounts; (c) your violation of any law or third party’s rights; or (d) Customer Data, except to the extent caused by SenderRank’s breach of these Terms.
19. Governing Law and Dispute Resolution
These Terms are governed by the laws of [State/Country of Governing Law], without regard to its conflict-of-laws principles. The parties agree to first attempt to resolve any dispute informally by contacting legal@senderrank.com. If a dispute is not resolved within 30 days, it will be subject to the exclusive jurisdiction of the courts located in [Venue], and each party consents to personal jurisdiction there.
20. General Provisions

- Changes to these Terms: We may update these Terms from time to time. We will post the updated version with a revised “Last updated” date and, for material changes, provide additional notice. Continued use of the Service after changes take effect constitutes acceptance.
- Assignment: You may not assign these Terms without our prior written consent; we may assign these Terms in connection with a merger, acquisition, or sale of assets.
- Severability: If any provision of these Terms is found unenforceable, the remaining provisions remain in full effect.
- No waiver: Our failure to enforce any right or provision is not a waiver of that right or provision.
- Force majeure: Neither party is liable for delay or failure to perform caused by circumstances beyond its reasonable control.
- No partnership: These Terms do not create any partnership, joint venture, employment, or agency relationship between you and SenderRank, other than the agency-client data relationship described in Section 4.
