Acceptable Use Policy

Last updated: 27 October 2026

1. Who this applies to

This policy applies to everyone who uses Vaartix ("you"), including your team members and any application that sends email with your API keys or SMTP credentials. Vaartix is operated by NAP Designs, India ("we", "us"). This policy forms part of our Terms of Service.

2. What Vaartix is for

Vaartix is built for transactional email: messages triggered by a recipient's action or relationship with your product. Examples:

• One-time passwords, login links and verification emails
• Order confirmations, receipts and invoices
• Password resets and security alerts
• Account, billing and service notifications

Bulk marketing, newsletters and promotional campaigns are not supported at this time.

3. Prohibited content and practices

You must not use Vaartix to send, or help send:

• Unsolicited email to anyone who has not given you clear permission to email them, including cold outreach in bulk.
• Email to purchased, rented, shared, scraped or harvested address lists.
• Phishing, credential harvesting, or messages that impersonate another person, brand, bank or government body.
• Malware, viruses, or links to files or sites that host them.
• Messages with false or misleading sender names, subject lines or headers.
• Content that is illegal in India or in the recipient's country, including fraud, scams, and content that infringes intellectual property.
• Gambling, betting, adult or sexually explicit content, or promotions for illegal drugs, weapons or counterfeit goods.
• Get-rich-quick, pyramid or multi-level marketing schemes, and unlicensed financial or investment offers.
• Harassment, threats, hate speech, or content that exploits minors.

You must also not:

• Try to bypass sending limits, suppression lists or account reviews, or open multiple accounts to do so.
• Trigger OTP or verification emails in bulk to addresses you don't own (including "OTP pumping").
• Probe, scan or attack Vaartix's systems, or interfere with other customers.
• Share your API keys publicly or let unauthorised parties send through your account.

4. Your responsibilities as a sender

• Permission: only email people who expect to hear from you, and keep a record of how they signed up.
• Accurate identity: send from a domain you own and have verified, with a sender name your recipients will recognise.
• Opt-out: any non-essential notification must include a clear way to stop receiving it, and you must honour requests promptly.
• List hygiene: don't retry addresses that bounce; we suppress hard bounces and complaints automatically, and you must not work around this.
• Healthy rates: keep your bounce rate below 4% and your spam complaint rate below 0.08%. Accounts above these levels are paused automatically.
• Law: comply with applicable laws, including India's Information Technology Act, 2000 and Digital Personal Data Protection Act, 2023, and the anti-spam laws of your recipients' countries.

5. How we enforce this policy

To protect deliverability for every customer, we monitor sending volumes, bounce and complaint rates, and content signals. New accounts start with low daily limits that increase with a clean sending history, and we may review accounts manually.

If we believe you have broken this policy, we may, with or without notice:

• Lower your sending limits or pause sending
• Ask you for information about your recipients and how they opted in
• Suspend or terminate your account
• Report illegal activity to the relevant authorities

Where possible, we'll tell you what happened and how to fix it before restoring sending.

6. Reporting abuse

If you received an unwanted or suspicious email sent through Vaartix, please forward it with full headers to [email protected]. We review every report.

7. Changes

We may update this policy as Vaartix grows. We'll post the new version on this page with a new date, and notify customers by email of significant changes.
