Maropost – Acceptable Use Policy

Effective Date: June 15, 2021

At Maropost, we want our customers to only send emails to contacts who truly want to receive them, otherwise, they’re sending spam. That’s why we require you to have permission from all of your contacts in order to email them. There are a few rules to be aware of when it comes to the types of email addresses you can are able to send emails to and the types of permission you are granted for sending to them. This Acceptable Use Policy (“AUP”) describes activities that are not allowed in connection with your use of the Services. The AUP is incorporated by reference in your Agreement.

Maropost and its partners only support permission-based and lawful email/mobile marketing practices that comply with but are not limited to regulations such as Canadian Anti-Spam Laws (“CASL”), United States Controlling the Assault of Non-Solicited Pornography and Marketing or (“CAN-SPAM“) Act, United States Telephone Consumer Protection Act (TCPA), or privacy regulations like General Data Protection Regulation (GDPR).

Closed-Loop Authentication List Building
Maropost products enable clients to put an ‘opt-in’ form on their website. This feature collects and stores the email addresses of permission-based recipients. All Maropost products also have an option to use closed-loop authentication: an email address is not added to the recipient list until a link is clicked in the confirmation email. This process is implemented completely by the software.

Contact List Abuse Prevention
Maropost technology automatically screens email campaigns for indicators of potential problems such as blacklisting and high spam scores. Any Maropost account email campaign that surpasses a threshold is automatically suspended until the Postmaster reviews and clears it.

To protect Maropost’s reputation, and that of its clients, Maropost offers to help new customers upload their first large email distribution list. This service allows Maropost to view the contents of an email distribution list, with the customer’s permission. In addition, Maropost helps first time customers run a sample email campaign to a few select recipients from their list before sending it to the rest.

Software Control Tools
Maropost provides its customers with certain tools to assist in compliance with Email and Privacy regulations. For example, Maropost products independently add an unsubscribe option to each email sent. Unsubscribes can be requested via a link in each email that goes to a landing page where users can unsubscribe from all or some lists.

This option cannot be removed by the customer; however, they can choose how it will be phrased. Anyone who unsubscribes will be automatically flagged in the database and their email address will be suppressed from all future mailings. Unsubscribe status can not be overwritten by list merging. To further protect recipients from email abuse, contacts receiving emails sent using the Maropost products will only see their names in the ‘To’ field. No other recipients’ email addresses are visible.

Email Sending Practices
Maropost honors ISP and Mailbox providers policies (restrictions on the number of connections, speed of sending servers, open relay off, reverse DNS enabled, RFC compliance). Authentication standards, such as sender policy framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication Reporting and Conformance (DMARC) are used for outgoing email campaigns. Maropost products distinguish between soft and hard bounces. Hard bounces (bad email addresses) are immediately flagged and suppressed from future mailings.

Suppression File Encryption
Maropost supports suppression file encryption. Suppression file abuse is a significant source of spam. The simple act of encrypting these files makes this sort of abuse more difficult. The Email Sender and Provider Coalition (ESPC) has implemented a membership requirement that members should support MD5 suppression file encryption. It is our hope that adoption of this standard will not only help reduce spam but also drive broader encryption adoption within the industry. You can read more by clicking here.

Dealing with Complaints
As customers use Maropost systems, the number of complaints they receive is tracked by an internal reputation and tracking system. Customers with a high number of complaints may be subject to list upload restrictions. Larger lists are uploaded not by the customer, but by Maropost upon the customer’s instruction, and may be subject to manual scrutiny.

When a complaint is received the following process is followed:

User addresses from complaints received via ISP or Mailbox providers Feedback Loops (FBLs) are automatically unsubscribed. Complaints received directly from end-users or via third-party sources like SpamCop, are reviewed by our Postmaster team and the account is subject to suspension. The user address is unsubscribed (manually added to the account’s Do Not Mail list) and we track such reports. We may ask our customers to provide proof of consent in such cases. We may also ask our customers to reconfirm their lists, as needed.

Maropost reserves the right to assess a fee against clients of up to, the greater of $1,000 and 10% of their monthly fees, for each account suspension caused by the client delivering emails that are reasonably deemed unacceptably spam or bounce heavy by Maropost, including, without limitation, due to complaints arising from Blocklists like Spamhaus, SURBL listings, mailbox providers or similar organizations, services or lists. These fees are cumulative if issues continue. These fees, which represent liquidated damages and not a penalty or fine, will be chargeable upon each incident of spam complaint or reasonable apprehension of spam heavy content. In addition to the above, and without prejudice to Maropost’s entitlement to fees owing under a subscription agreement, Maropost may, at its sole discretion, terminate the customer accounts of repeat, or otherwise egregious, offenders hereunder.

End users should only receive emails from our system sent on behalf of our customers that they recognize opting in to. We do not allow any customer to use our platform to send unsolicited emails.

If you have received an unsolicited email from one of Maropost’s customers, please contact

Acceptable Guidelines for Customers
Below are some guidelines around list collection, identification, unsubscribe, and content requirements that need to be followed by all Maropost customers.

Maropost requires its customers to ensure they have proper opt-in permission (explicit, express, or implied) for each recipient in their list. Customers are also required to produce proof of opt-in or prior relationship upon request within 72 hours of receipt of a request by the recipient or Maropost. You must use reasonable means to ensure that the person giving consent is the owner of the e-mail address for which the consent is given. Customers are encouraged to ensure they are emailing end users only for the purposes for which their consent has been collected. For example: If has consented to receive a one-time product update from Brand A, their email address should not be used to send Brand A’s general periodic email newsletter.

Explicit or Express Consent
Recipients must express their choice to receive one or more types of emails. Note that consent must be collected using an opt-in mechanism and not an opt-out mechanism. The recipient must take positive action to indicate their consent. Note that express consent may be collected both orally or in writing.

Co-registration on a partner’s website may be acceptable so long as there are separate opt-in options for each list and the recipient is presented with options and choices in a clear and conspicuous manner. For example, recipient choice to consent to one email list should not be construed as consent to receive email from multiple partner lists.

Below are some common sources of collecting express consent:

  • Online webform
  • Offline form, paper ballot
  • Call center

Implied consent
Recipients must have had a prior business or non-business relationship, in most cases within the last two (2) years. There are some other forms of implied consent as well like:

  • The recipient has provided an email address without indicating a wish to receive unsolicited emails and the emails are relevant to the person’s business or official capacity.
  • For example, you may get implicit permission through:
    • The exchange of business cards.
    • A verbal request.
    • A fishbowl collection where no consent to email is asked.
    • The sale of a product or service.
    • An inquiry about a product or service.
    • A donation to your nonprofit organization.
    • Membership to your organization.

Below forms of acquiring email addresses may not provide adequate consent (not an exhaustive list):

  • Email addresses obtained from a third party: Any purchased, rented, or appended list of email addresses from any source, no matter what the source claims.
  • Any shared list of email addresses that haven’t given you direct permission to email, such as:
    • an affiliated company contact list.
    • a trade show attendee list.
  • Address harvesting, Dictionary attacks: These are ways of fraudulently collecting email addresses using various software tools like bots, scrapers, etc., or by attempting to guess email addresses using common usernames at a particular domain.
  • Correcting typos – Creating new email addresses by correcting common typos in either local part or domain part of email addresses.
  • Any collected email addresses obtained by surfing the internet or “scraping” web pages.
  • Role account type email addresses are typically risky in terms of proving consent because users of such addresses change frequently. Role account-based email addresses like:
  • Distribution lists – Since these types of addresses forward email to multiple persons, it is usually very onerous to collect consent from all recipients. Distribution list addresses like:
    • a voter registration list.
    • public directories.
    • membership association contacts.
    • chamber of commerce.
  • Any addresses obtained through social media connections where the contact has not explicitly requested mailings. This includes:
    • Facebook friends.
    • LinkedIn connections.
    • Twitter followers.
    • Instagram followers.
  • Addresses collected using opt-in pages that may be deceptive/ misleading, this includes but is not limited to, misleading users about the products/ services advertised.

Every email sent using the Maropost platform must include a clear, conspicuous unsubscribe mechanism that is simple and easy to use. Maropost automatically includes such functionality in the footer of every email.

However, if customers wish to add additional unsubscribe links in the content, Maropost provides the option of using several ‘campaign tags’ to add an unsubscribe link in outgoing emails. Such unsubscribe requests are captured by Maropost software and relevant user addresses are automatically removed from the applicable mailing lists. Customers are responsible for choosing a ‘campaign tag’ that is optimized for their campaign type and recipient selection method. Customers are also responsible to make sure it is coded correctly within their email content.

In case customers use some other unsubscribe link, a plan should be in place to make sure users opting out using such means are marked as unsubscribed in Maropost.

We understand that this may not be entirely feasible, so we discourage customers from using non-Maropost unsubscribe links. Using unsubscribe links belonging to third-party advertisers is very risky because the user never opted into the advertiser and it is challenging to make sure all such users are properly unsubscribed in Maropost.

Maropost also advises customers to ensure singular opt-in does not have multiple opt-outs. Example: If the end user is subscribing to List A, then the sender should not auto-subscribe user address to List B, List C and List D. In case the sender does that, they should ensure that unsubscribe action in any email actually opts the user out of all applicable lists (A, B, C, D).

Snowshoe Spamming or Waterfalling
Snowshoe spamming is an abusive sending technique used in an attempt to avoid email filters. Named for the similarity to how a snowshoe distributes the load of a traveler across a wide area of snow, snowshoe spamming spreads spam across many IPs and domains in order to dilute reputation metrics and evade filters. Furthermore, the practice of switching domains is considered against best practices and your sending reputation will be negatively affected and generally unrecoverable.

It is at the sole discretion of Maropost to determine if the use of multiple IPs or domains are being used for such a practice. If it is determined that Snowshoeing is occurring, Maropost at its sole discretion may suspend or terminate your account.

Waterfalling is an abusive technique wherein a list owner “waterfall” the same illicitly obtained address list through a series of (usually) unknowing, innocent ESPs. Each time they clean out bounces, complainants, and maybe non-respondents, with the end goal being to send the final result through a good ESP with solid deliverability.

The result of this process damages the reputation of each ESP involved, as well as being a violation of ethics, counter to best practices and against our policy.

It is at the sole discretion of Maropost to determine if Waterfalling is being used. If it is determined that Waterfalling is occurring, Maropost at its sole discretion may suspend or terminate your account.

Maropost requires its customers to accurately identify themselves in emails sent out of their account:

  • You must have a Privacy Policy posted for each domain associated with the mailing
  • Your Privacy Policy must clearly notify recipients if you intended to share their email addresses with third parties OR in accordance with applicable privacy and email regulations obtain the proper permissions to do such.
  • We require senders to have friendly From addresses’ that are accurate, relevant, and consistent on all senders’ messages since emails not matching those best common practices are more highly likely to be marked as spam. This needs to accurately identify the sender of the message (Senders need to introduce themselves to the recipients with relevant, accurate, and consistent name on all their messages).
  • The “Display Name” field must identify the sender of an email that the recipient has opted into. It can be a person, a company, a department, etc., but may not be used as a secondary Subject line. It must be recognizable to the recipient.
  • Subject lines: These need to accurately reflect the purpose of the email.
  • Identification requirements: The sender of the message needs to be clearly identified in the message. In case the message is being sent on someone’s behalf (advertiser), both parties need to be clearly identified in the message.
  • Contact information: Mailing address and either of the following contact information pertaining to the sender needs to be mentioned in the message: telephone number, email address, web address.
  • Statement: In case the message is being sent on behalf of someone else (advertiser), a statement indicating which person is sending the message and which person on whose behalf the message is being sent needs to be mentioned in the message.

We prohibit customers from sending certain types of content (not an exhaustive list):

  • Emails offering illegal goods or services.
  • Emails that violate the CAN-SPAM act or other anti-spam laws
  • Pornography/sexually explicit content
  • Escort services, mail-order bride/spouse finders, international marriage brokers, and other similar sites and services
  • Hookup, swinger, or sexual encounter sites or services
  • Dating services
  • Promoting or supporting terrorism or violent extremism
  • Counterfeit products or products that infringe the intellectual property rights of others, including trademark, copyright, design or patent rights
  • Pharmaceutical products
  • Products claiming to prevent, treat, or cure COVID-19 that are not approved or authorized for emergency use by regulatory or public health agencies, such as the FDA in the U.S.
  • Products that are in demand due to COVID-19 with excessive pricing, price gouging, or deceptive pricing practices or in demand due to COVID-19 and prohibited by applicable law
  • Emails that have false or misleading representation in the email, including subject lines.
  • Emails containing URLs that link to pages that spoof known brands and ask users to download suspicious content.
  • Work from home, internet ‘get rich’ schemes, lead generation opportunities.
  • Network marketing, pyramid schemes, and multi-level marketing.
  • Credit repair and get out of debt opportunities.
  • No online trading, day trading tips, penny stocks, Exchange of currencies, fraudulent shares or stock market related content
  • Cryptocurrencies and virtual currencies.
  • Real-money gambling.
  • Payday loans
  • Multi-level marketing
  • Affiliate marketing
  • Credit repair and get out of debt opportunities
  • List brokers or list rental services
  • Selling “Likes” or followers for a social media platform

With regards to the From: domains; we require customers to ensure they maintain proper DNS entries – A (IP address), TXT (for SPF, DKIM, and DMARC authentication records). Customers also need to ensure they have proper MX records for the Reply-to domain.

From address must be a registered domain and clearly identify the sender. Customer must own or have permission to utilize the From Domain and the domain must have a functional “live” site that ties back to the Customer.

If from or reply address is unmonitored, it must have an autoresponder detailing that it is unmonitored, as well as alternative ways to contact the Customer. A monitored email address must be one of those included forms of communication.

It is also prohibited to use any form of Private WHOIS registration.

ISPs assign a fair bit of reputation to From: domains and we discourage customers from rotating these domains frequently because ISPs regard this as an attempt to circumvent filtering. This includes rotating both the domain and the subdomain. Example: Similar mail should not be sent from many domains like,,,,, Instead, all this mail should be sent from
