Maildoso Terms of Service

Last updated on 1 October 2026.

These Terms of Service ("Terms") govern your use of maildoso.ai and any related services provided by BacklinkSwappers, Inc., d/b/a Maildoso ("Maildoso", "we", "us"). By accessing the website or the platform, you agree to abide by these Terms and all applicable laws and regulations. If you do not agree, you may not use this website or any associated services.
We may amend these Terms at any time at our sole discretion. Changes take effect immediately upon publication on this page. We review these Terms periodically to keep them accurate and up to date.

Limitations of Use

By using this website or our services, you warrant on behalf of yourself, your users, and other parties you represent that you will not:
  • modify, copy, prepare derivative works of, decompile, or reverse engineer any materials or software on this website;
  • remove any copyright or other proprietary notations from any materials;
  • transfer materials to another person or mirror them on any other server;
  • knowingly or negligently use this website or its associated services in a way that abuses or disrupts our networks or any other service we provide;
  • use this website or its associated services to transmit or publish harassing, indecent, obscene, fraudulent, or unlawful material;
  • use this website or its associated services in violation of any applicable laws or regulations;
  • use this website or its associated services to send unauthorized advertising or spam;
  • harvest, collect, or gather user data without the user's consent; or
  • use this website or its associated services in a way that may infringe the privacy, intellectual property, or other rights of third parties.

Intellectual Property

The intellectual property in the materials on this website is owned by or licensed to Maildoso and is protected by applicable copyright and trademark law. We grant users permission to download one copy of the materials for personal, non-commercial, transitory use. This is a license, not a transfer of title. The license terminates automatically if you breach these Terms and may be terminated by Maildoso at any time.

Liability

Our website, services, and the materials on our website are provided on an "as is" basis. To the extent permitted by law, and except as expressly provided in the Email Deliverability Guarantee below, Maildoso makes no warranties, expressed or implied, and disclaims all other warranties, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement of intellectual property or other rights.

To the extent permitted by law, Maildoso's liability to you is limited as follows:
(a) Excluded loss. Maildoso and its suppliers are not liable for any indirect or consequential loss arising from the use or inability to use this website, our services, or the materials on this website, even if Maildoso has been notified of the possibility of such loss. This includes loss of profit, revenue, business, goodwill, opportunity, savings, or reputation, loss of use, and loss or corruption of data, whether under statute, contract, equity, tort (including negligence), indemnity, or otherwise.

(b) Cap on remaining liability. For any other loss (direct loss), Maildoso's total liability arising out of or relating to these Terms or the services shall not exceed the amount paid by you to Maildoso in the three months preceding the event giving rise to the claim.

Because some jurisdictions do not allow limitations on implied warranties or limitations of liability for consequential or incidental damages, these limitations may not apply to you.

Accuracy of Materials and Links

The materials on this website are for general information purposes only and are not comprehensive. Maildoso does not warrant the accuracy or reliability of these materials or of any linked third-party resources. We have not reviewed all sites linked from this website and are not responsible for their contents; the inclusion of a link does not imply endorsement. Use of any linked site is at your own risk.

Sending Limits and Warm-up

Maildoso provides sending infrastructure (domains and mailboxes). Maildoso does not provide a mailbox warm-up service. Warm-up is performed by the client using a third-party warm-up or sequencing tool of their choice.

To protect deliverability, clients agree to the following practices:
  • Warm up each new mailbox for a minimum of 14 days before starting cold email campaigns.
  • After warm-up, gradually increase volume from 1 email per day to a maximum of 15 cold emails per day per mailbox, including follow-ups.
  • Verify all recipient email addresses before sending and maintain a bounce rate below 2%.
  • Include a visible, functional unsubscribe link in every email.
  • Refrain from sending spam-related content.

Email Deliverability Guarantee

Maildoso aims to maintain a minimum 80% inbox placement rate for emails sent through our infrastructure. If this rate is not met, we will investigate the cause. To be eligible for this guarantee, clients must comply with the Sending Limits and Warm-up section above.

If non-deliverability results from domain performance issues outside the client's control, we will provide replacement domains at no extra cost. This guarantee is valid for one year from the date of domain purchase. Each customer is entitled to up to 4 domain replacements.

Email Recipients

Our services are intended exclusively for outreach to corporate email addresses. Clients may not send emails to personal email accounts (e.g., @gmail.com, @yahoo.com, @hotmail.com). It is the client's responsibility to ensure that all recipients hold corporate email addresses.

Unsubscribe Links

Every email sent through our services must include a visible, functional unsubscribe link. Clients must maintain accurate records of individuals who have opted out and must honor all unsubscribe requests promptly.

Failure to include an unsubscribe link, failure to honor opt-out requests, or continued sending to unsubscribed recipients may result in immediate suspension or termination of service.

Domain Registration and Ownership

Maildoso offers domain registration both as part of its packages and as a standalone purchase, including without purchasing mailboxes. Domains purchased through Maildoso are registered to and managed by Maildoso. To provide uninterrupted service (mailbox creation, IP rotation, and related processes), Maildoso retains full control over these domains for as long as they are serviced on the platform. Clients may request ownership of their domains, and we will facilitate the transfer at no cost.

Refund and Cancellation

Refunds for mailbox subscriptions are available only within 30 days of the first payment date, and only under the single condition below. Maildoso does not offer refunds on any other grounds, including dissatisfaction with the product or changes in the client's plans.

Refund condition. A refund may be issued if the client's mailboxes fail to send emails for 3 or more consecutive days due to a fault on Maildoso's side. The failure must be reported to Maildoso and verified by our team. All other refund requests will be declined.

Domains. Domain purchases and renewals are non-refundable under all circumstances. If mailboxes and domains were purchased on a single invoice, domain charges ($15 per domain) are deducted from any refund issued for the mailboxes. If domains were purchased on a separate invoice, a refund for mailboxes covers the full amount of the mailbox invoice.

A refund request will be declined if any of the following applies:
  • the request is made more than 30 days after the first payment date;
  • the issue results from violation of these Terms, including the Sending Limits and Warm-up section;
  • the issue results from misuse of the service;
  • the issue results from external factors beyond our control (e.g., third-party service disruptions or client-side issues);
  • cold emails were sent in excess of 15 per day per mailbox;
  • the minimum 14-day warm-up period was not completed;
  • the unsubscribe link was omitted from email campaigns;
  • emails were sent in bulk to personal email addresses (@gmail.com, @hotmail.com, @yahoo.com, etc.);
  • the request concerns services not advertised on our website or outside the scope of the purchased package;
  • mailboxes were deleted before the end of the refund dispute period;
  • the subscription was not cancelled before the renewal date.

Refund dispute process. All refund requests undergo review; please allow 3 business days for resolution. Mailboxes must not be deleted during the 3-business-day dispute period; deletion before the period ends invalidates the refund request. Partial refunds, where applicable, are calculated by deducting the days of service used and, where purchased on the same invoice, domain charges from the total subscription amount.

Renewals

All subscriptions, for mailboxes and for domains, renew automatically on the renewal date. Our payment partner, Stripe, sends a renewal notification 1 week before that date. To cancel, the client must cancel from the billing page or notify Maildoso through official communication channels before the renewal date. No refund is issued for a renewal that was not cancelled in advance; failure to cancel is entirely the client's responsibility.

Domains are billed as an annual subscription, either as part of a mailbox subscription where domains are included in the package, or as a separate domain subscription. The standard renewal price is $15 per domain per year. If the subscription is cancelled or the payment fails, the domain is not renewed.

If a domain's renewal price exceeds $15 (for example, due to a registrar price change), Maildoso will notify the client at least 7 days before the renewal date, stating the actual amount. The client must confirm the renewal at the new price within 3 business days of the notification; without confirmation, the domain is not renewed.

Maildoso reserves the right to deny domain renewals at its discretion.

Termination

Maildoso may suspend or terminate your access to the website and services, and terminate these Terms, immediately upon written notice for any breach of these Terms.

Customer Feedback and Testimonials

Feedback, testimonials, or information shared by customers via email or in conversations with our team may be used for case studies or testimonials without requiring separate permission. We also reserve the right to state on our website that a customer uses our product. Customers may at any time request that their feedback not be used or that their logo be removed, and we will honor such requests promptly.

Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States. You irrevocably submit to the exclusive jurisdiction of the courts of the State of Delaware.

Severance

Any term of these Terms that is wholly or partially void or unenforceable is severed to the extent that it is void or unenforceable. The validity of the remaining Terms is not affected.
