Acceptable Use Policy

1. Permission to email (no purchased lists)

You may only send email to recipients who have given you permission to contact them, or where you have another valid lawful basis to do so. You are strictly prohibited from sending to:

• Purchased, rented, leased, or otherwise acquired third-party lists.
• Scraped, harvested, or appended email addresses.
• Recipients who have not opted in or who have no prior relationship with you.
• Anyone who has unsubscribed, marked your mail as spam, or asked you to stop.

When you build an audience from an uploaded file or a Monday board, you confirm that you have consent — or another lawful basis — to email those contacts. That confirmation is your representation to us, and you are responsible for its accuracy.

2. Prohibited content

You may not use MailMonk to create, send, or link to content that is illegal, deceptive, or harmful. MailMonk applies an automated content-safety scan to campaigns, and we may suspend sending where content falls into any of the following categories:

• Phishing & credential harvesting — impersonating a person, brand, or institution to obtain passwords, payment details, or other sensitive information.
• Fraud & scams — deceptive financial schemes, fake invoices, “too good to be true” offers, advance-fee fraud, and similar.
• Malware & malicious links — attachments or URLs that distribute viruses, spyware, ransomware, or lead to harmful sites.
• Hate, harassment & threats — content that attacks, demeans, or incites violence against people or groups.
• Sexual & adult content — pornographic or sexually explicit material.
• Illegal or regulated goods — drugs, weapons, counterfeit products, and other goods or services unlawful to promote.
• Deceptive sending practices — falsified headers, misleading “from” names, or subject lines that misrepresent the message.

You remain solely responsible for the content you send. MailMonk acts as a technical conduit and does not endorse or guarantee review of any message prior to dispatch.

3. Required campaign elements

Every marketing or bulk campaign you send must include:

• A functional, single-click unsubscribe mechanism, honored promptly.
• A valid physical mailing address for the sender.
• Accurate “from” identity and a subject line that reflects the message’s content.

MailMonk adds compliant unsubscribe links and headers automatically; you must not remove, obscure, or defeat them.

4. Deliverability obligations (bounce & complaint rates)

To protect shared deliverability, you must keep your sending metrics within industry-standard thresholds. MailMonk monitors these continuously and may automatically pause or restrict sending — and, on repeated or severe breaches, suspend your account — when you exceed limits including:

• A spam complaint rate exceeding 0.1%.
• A hard bounce rate exceeding 5%.
• Detection of spam traps or honeypot addresses in your recipient lists.

You are expected to maintain clean lists, remove repeated bounces, and stop emailing recipients who do not engage. When sending is paused for a deliverability problem, you can clean up your list and resume once metrics return to acceptable levels.

5. Sending limits & infrastructure protection

MailMonk applies sending caps and pacing based on your plan, account age, and track record. You may not attempt to circumvent these limits — for example by creating multiple accounts, splitting a single audience across accounts, or registering domains to evade enforcement. We may decline, throttle, or queue sends to protect our infrastructure and the reputation of our shared sending domain.

6. Compliance with law

You are solely responsible for ensuring your use of MailMonk complies with all applicable local, state, national, and international laws, including but not limited to:

• The CAN-SPAM Act (USA)
• The General Data Protection Regulation (GDPR) (EU)
• Canada’s Anti-Spam Legislation (CASL)

7. Enforcement & suspension

We reserve the right to warn, restrict, suspend, or terminate your account — with or without notice, and without refund — if you violate this policy, exceed the thresholds above, or otherwise threaten the integrity, legality, or deliverability of our service. Enforcement may be automated. We may also remove access to our shared sending address while permitting sending from your own verified domain, or vice versa, at our discretion. These remedies are in addition to any rights described in our Terms of Use.

8. Reporting abuse

If you believe email sent through MailMonk violates this policy, please contact us at abuse@mailmonk.app. We investigate reports of abuse and take appropriate action.
