Sending Policy
Last updated: 6 May 2026
This Sending Policy sets out the rules that apply to all communications sent through the Hileadplatform (the “Service”) provided by Hilead Ltd (“Hilead”, “we”, “us”). It supplements our Terms of Serviceand is binding on all customers (“you”, “your”).
The purpose of this policy is twofold:
- Protect recipients from unwanted, harmful, or unlawful communications.
- Protect the deliverability and reputation of the Service for all customers.
By using the Service to send communications, you agree to comply with this policy. Violations may result in immediate suspension or termination of your account, without refund.
1. Scope
This policy applies to all outbound communications sent through the Service, including but not limited to:
- Email outreach and follow-ups.
- Automated sequences and cadences.
- Any other channel made available through the Service.
2. Lawful sending
You must comply with all applicable laws in the jurisdictions where:
- You are established.
- Your recipients are located.
- Your sending infrastructure operates.
This includes, without limitation:
- United Kingdom: Privacy and Electronic Communications Regulations (PECR), Data Protection Act 2018, UK GDPR.
- European Union: ePrivacy Directive, EU GDPR.
- United States: CAN-SPAM Act (15 U.S.C. § 7701 et seq.).
- Canada: Canadian Anti-Spam Legislation (CASL).
- Australia: Spam Act 2003.
You are solely responsible for determining what laws apply to your sending and ensuring compliance.
3. Required elements in every message
Every email you send through the Service must include, at minimum:
- A clear identification of the sender (your name and / or your company).
- A valid physical postal address for the sender.
- An unsubscribe mechanism that is functional, easy to use, free of charge, and honoured within 10 business days.
- An accurate subject line that is not deceptive or misleading.
- Accurate header and routing information(no spoofing, no false “From” or “Reply-To” addresses).
Failure to include these elements will be considered a material breach of this policy.
4. Targeting rules
4.1 Permitted targets
You may use the Service to contact:
- Business professionals in their professional capacity, where you have a legitimate business reason to contact them and where applicable law permits B2B outreach without prior consent.
- Recipients who have given their explicit consent to receive your communications.
- Existing customers and prospects with whom you have a prior business relationship, in line with applicable laws.
4.2 Prohibited targets
You may not use the Service to contact:
- Individuals in their personal capacity (consumers).
- Recipients who have opted out of your communications, regardless of the channel through which they opted out.
- Recipients whose data was obtained unlawfully, including from data leaks, breaches, or unauthorised scraping.
- Recipients in jurisdictions that prohibit B2B outreach without prior consent (such as Germany under certain circumstances), unless you have obtained the required consent.
- Generic role-based addresses (e.g., info@, contact@, abuse@, postmaster@, support@) at scale, except where directly relevant to your offering.
- Honeypot and spam-trap addresses (you are responsible for keeping your lists clean).
5. Content restrictions
You may not use the Service to send content that:
- Promotes illegal goods or services.
- Promotes adult content, pornography, or sexually explicit material.

6. Volume and frequency
You must keep volumes reasonable and appropriate to your sending infrastructure and reputation:
- Warm up new sending domains and addresses before sending at scale.
- Respect rate limits imposed by the Service and by recipient mail servers.
- Avoid sudden spikes in volume that may trigger spam filters.
- Use sub-sending limits as recommended by deliverability best practices (typically no more than 30-50 emails per address per day on cold outreach).
We reserve the right to throttle, suspend, or terminate accounts whose sending patterns harm Service reputation.
7. Deliverability hygiene
You must:
- Authenticate your sending domains with SPF, DKIM, and DMARC records.
- Use a custom domain for outbound sending(no shared “@hilead.co” sending).
- Maintain bounce rates below 5% and complaint rates below 0.3%.
- Remove invalid, bouncing, or complaining addresses from your lists promptly.
- Honour opt-outs within 10 business days at the latest, ideally immediately.
- Maintain accurate suppression lists across all your campaigns.
We may automatically pause campaigns that exceed deliverability thresholds.
8. List sources
You may use the Service to engage with:
- Prospects identified through Hilead’s database.
- Lists you have lawfully built or sourced from compliant providers.

- Obtained through data breaches or leaks.

We may, at our discretion, request evidence of how a given list was sourced. Failure to provide reasonable evidence within 5 business days may result in suspension of your campaigns.
