Terms and Conditions

01About the Service and eligibility

HTsend helps businesses and organizations manage email sending, campaigns, templates, contacts, sending domains and related workflows. We do not determine whether a particular campaign or list complies with laws applying to your business.

You must have legal capacity to enter these Terms. If you use HTsend for an organization, you confirm that you are authorized to accept these Terms for it. You must provide accurate information and may not impersonate another person or conceal who is responsible for sending.

02Account registration and security

You are responsible for:

• Keeping your login credentials, API keys and authentication details secure.
• Maintaining accurate account, sender and billing information.
• Protecting access to your account, domains, devices and connected systems.
• All activity performed through your account by you or anyone you authorize.

Do not share credentials with unauthorized persons. Contact us promptly if you suspect a compromise. We may require additional verification to protect customers, recipients or the Service. Practical account guidance is available in our documentation.

03Acceptable email use, consent and lists

HTsend is for legitimate, permission-based communication. You must have an appropriate legal basis and, where required, permission to send each recipient the type of message you send. Keep appropriate records of how recipients were obtained and how consent was given.

You must not upload or use lists that were purchased, rented, scraped, harvested, obtained without authorization, or collected unlawfully.

Prohibited email and activity

• Unsolicited bulk email, spam, repeated messages to people who opted out, or deliberate spam-trap targeting.
• Phishing, credential theft, impersonation, fraud, scams, malware, ransomware or malicious files and links.
• Illegal, threatening, harassing, deceptive or abusive content, or content promoting illegal activity.
• Attempts to evade spam filters, manipulate reputation, bypass security controls, scan systems without authorization or exploit vulnerabilities.

Unsubscribe and suppression

Marketing and promotional email must include a clear, functioning opt-out where required by law. You must honor valid requests promptly and keep suppression records so opted-out, bounced or complaining recipients are not accidentally re-added. Transactional messages may be treated differently, but you are responsible for classifying them correctly.

Commercial email may also require accurate sender details, truthful subjects, a valid physical postal address and timely opt-out processing. Using an email platform does not remove the sender's responsibilities. Read the full Anti-Spam Policy, which is incorporated into these Terms.

Sender identity and content

You must use accurate From, Reply-To, routing and subject information. You may not impersonate another person or organization, disguise the sender, use a domain you do not control, or misrepresent the purpose of a message. Your content must accurately represent the relevant business, product, service or communication.

04Domains, DNS and deliverability

You must own or be authorized to use every connected domain. You are responsible for its registration, DNS access, required authentication records and protection from unauthorized sending. HTsend may provide instructions for SPF, DKIM and DMARC, but you remain responsible for keeping those records correct.

No email service can guarantee inbox placement. A message may reach an inbox or spam folder, be delayed, deferred, rejected or blocked. Results depend on recipient engagement, sender, domain and network reputation, authentication, content, bounce and complaint rates, prior behavior, and receiving-provider rules. We do not promise a delivery, inbox-placement, open, click, response or conversion rate.

We may monitor sending signals necessary to identify spam, excessive bounces, complaints, compromised accounts, unusual patterns, security threats or fraud. We may investigate reports from recipients, receiving providers or security organizations and request evidence about a list or campaign before allowing sending to continue.

05Customer data, content and privacy

You retain your rights to contacts, campaign content, templates and other materials you provide. You grant HTsend only the limited rights necessary to process and transmit that content to operate the Service, secure it, prevent abuse, troubleshoot, comply with law and enforce these Terms.

HTsend does not sell your contact information or use recipient lists for its own marketing. Information may be processed or technically handled when necessary to deliver email, operate the Service, authenticate requests, prevent abuse, detect threats, maintain reliability, troubleshoot, meet legal duties or protect customers and recipients. Our Privacy Policy explains this handling in more detail.

You are responsible for having the rights and permissions needed to upload, process and send your data. You must not submit information you are not legally authorized to use.

Templates, images and AI-assisted features

You must review all final material before sending. Automated or AI-assisted tools may produce inaccurate, incomplete, unsuitable or inappropriate output. You are responsible for factual accuracy, claims, links, images, branding, targeting, permissions, opt-out functionality and legal compliance. HTsend does not guarantee that generated content is correct or suitable for a particular audience.

Intellectual property

The HTsend software, interface, branding, logos, designs, documentation and underlying technology are owned by or licensed to HTsend. You may not copy, resell, reverse engineer, modify, distribute or commercially exploit proprietary technology except as expressly permitted. These Terms do not transfer HTsend intellectual property to you.

06Subscriptions, billing, cancellation and refunds

Paid plans renew according to the billing period selected. You authorize the payment provider to charge your chosen payment method and must keep billing information current. If payment fails, we may restrict paid features until it is resolved. Current allowances are shown on the pricing page and in your account.

Cancellation prevents future renewal and normally takes effect at the end of the paid period; it does not automatically reverse a completed charge or create a right to a refund.

Refund policy — all payments

This policy applies equally to all payments, regardless of how you pay. Except where required by law or expressly agreed in writing, payments are non-refundable. Dispatched emails and consumed email credits are non-refundable because the sending service has already been provided. Inbox placement, opens, clicks, replies or sales are not guaranteed and do not, by themselves, create a right to a refund for sending services already provided.

Unused purchases, duplicate charges, billing errors and verified failures to provide the paid service may be reviewed case by case. Approval is not automatic. Suspension for a breach of our sending rules does not, by itself, entitle you to a refund. Nothing in this policy limits mandatory consumer rights, remedies for unauthorized payments or other rights that cannot legally be excluded.

How to request a refund

• Contact us through the support page with your invoice reference, account email and the reason for your request. Never send passwords or sensitive payment credentials.
• We review the payment record, credits consumed, sending history and any reported service failure before making a decision. Credits used while a request is under review remain consumed.
• If approved, the refund covers only the amount agreed in writing. Corresponding unused credits and paid access must be removed or adjusted so refunded services cannot still be used. A refund does not restore the one-time free allowance.
• Approved refunds are returned through the original payment channel where supported; processing time depends on the payment service. We provide a written decision and confirmation when processed.

Plans may limit emails, contacts, campaigns, API use, domains, storage, templates or other features. You must not bypass quotas, rate limits or account restrictions. We may adjust reasonable limits to protect reliability and prevent abuse, and will provide reasonable notice where a change materially affects your rights or obligations.

07Monitoring, suspension and termination

We may temporarily restrict or suspend an account to prevent abuse, protect recipients or the Service, investigate suspicious activity, respond to complaints or security incidents, meet legal or infrastructure requirements, or enforce these Terms. We may act immediately where continued access creates significant legal, security, operational or reputational risk.

You may stop using HTsend at any time. We may terminate or restrict an account for a material or repeated breach, unlawful activity, serious abuse, non-payment, security risk or legitimate operational reason. Obligations arising before termination survive, as do provisions concerning ownership, payments, liability, indemnification and disputes.

Service and third-party availability

We work to keep HTsend reliable but do not guarantee uninterrupted or error-free operation. Maintenance, updates, security events, network or DNS problems, internet failures, legal requirements and third-party outages may affect availability. HTsend may rely on cloud, delivery, DNS, payment, analytics and security providers with their own terms and limitations. We are not responsible for independent failures or policy decisions made by those providers. Current service information is available on our status page.

08Compliance, warranties and legal responsibility

You must comply with laws applying to your business, location, recipients and communications, including electronic communications, marketing, privacy, consumer protection, advertising, intellectual property, cybersecurity and electronic transactions. HTsend does not provide legal advice; obtain professional advice for your circumstances where needed.

Disclaimer of warranties

To the maximum extent permitted by law, the Service is provided “as is” and “as available.” We do not warrant that it will always be uninterrupted, error-free, completely secure, compatible with every system, continuously available or suitable for every business purpose. Nothing excludes a warranty or consumer right that cannot legally be excluded.

Limitation of liability

To the maximum extent permitted by law, HTsend will not be liable for indirect, incidental, special, consequential, exemplary or punitive damages, including loss of profits, revenue, opportunities, goodwill, data or anticipated savings. HTsend's total liability arising from the Service is limited to the amount you paid HTsend during the 12 months immediately preceding the event giving rise to the claim, except where liability cannot legally be limited.

Third-party claims and indemnification

You are responsible for claims arising from your campaigns, lists, content, promoted products or services, use of third-party data, legal violations or infringement of another person's rights. To the extent permitted by law, you agree to defend and hold harmless HTsend, its affiliates, personnel, contractors and service providers from claims, losses, liabilities, damages and reasonable expenses arising from your unlawful use, content, lists, breach of these Terms, violation of law or infringement of rights.

Disputes

Before starting formal proceedings, you agree to give HTsend a reasonable opportunity to investigate and resolve the issue. This does not prevent either party from seeking urgent legal relief where necessary.

Force majeure

HTsend is not responsible for delay or failure caused by events beyond our reasonable control, including natural disasters, war, civil unrest, government action, widespread network or power failures, major infrastructure outages, third-party outages or cybersecurity incidents.

General provisions

If a provision is invalid or unenforceable, the remaining provisions continue. Failure to enforce a provision immediately is not a waiver. You may not transfer your account or rights without our prior written consent except where law permits. HTsend may assign its rights and obligations in a merger, acquisition, restructuring, asset sale or similar transaction.

These Terms, the Privacy Policy, the Anti-Spam Policy, and expressly incorporated policies form the agreement concerning the Service and replace prior understandings on the same subject, except where a separate written agreement applies.

09Changes to the Service or these Terms

We may add, change, suspend or discontinue Service features and may update pricing or limits. We may also revise these Terms. We will update the date above and, for material changes, may provide notice through the website, dashboard, email or another reasonable method. Continued use after revised Terms take effect means you accept them.
