If we decide, in our sole discretion, that the username you choose is improper, objectionable, or otherwise unacceptable, we have the right to remove, reclaim, or replace it. If you share your password, you will be responsible for the consumption that your account has.


The product may offer a Free Trial for consumers to test the product. When accessing the Free Trial, the consumer has to register and enter their credit card information. At the end of the trial period, if the client didn't previously cancel the subscription, SendYellow Ltd. will bill the amount corresponding to the subscription on a recurring basis until the consumer unsubscribes. SendYellow Ltd. won't accept refund requests for this reason. It is important to clarify that the consumer will be able to access the Free Trial only once. The second time the consumer subscribes to the product, it won't be able to access more than one Free Trial. SendYellow Ltd. reserves the right to discontinue the Free Trial or modify the trial period. The trial period will be announced on the website at the time of subscription. The consumer acknowledges and accepts that during the trial period they will not be able to claim any type of refund or compensation from SendYellow Ltd.

The Free Trial cannot be used for any commercial or public use or redistribution under any circumstances. The features provided in the free trial are licensed for personal use and for testing use only. Only the features provided using a paid subscription are licensed to allow public and commercial purposes and/or redistribution.


Only a paid Subscription is required to access the Service or certain portions of the Service. Depending on the type of Subscription plan you choose when purchasing the Subscription, you will be invoiced in advance on a recurring and periodic basis (such as daily, weekly, monthly, or annually). Unless you or the company decide to terminate it, Your Subscription will automatically renew at the end of each period under the same terms.

Refund Policy

Refunds are valid within 2 hours after the time of purchase and only apply to the first payment the product receives, as long as the consumer hasn't sent more emails or has a larger contact list than what's offered on the free plan.

Refund requests for duplicate payments made in months earlier than the current month won't be accepted.

After this period, claims for refunds will not be accepted. If we determine that you are eligible for a refund, we will refund the full purchase price of your subscription. Please note that any third-party fees associated with your purchase, such as credit card processing fees, may not be refunded. Refunds will be processed within 14 business days of our approval.

We will not accept a cancellation request from an email account different from the one used to register your account. Sending the email with the cancellation request does not mean that your account will be automatically canceled. You must wait for instructions or confirmation from our customer support team.

The opt-in function is a feature that enables recipients to voluntarily subscribe or provide their consent to receive emails from a specific sender or organization. It plays a crucial role in establishing a permission-based email list and ensuring compliance with email marketing regulations.

At SendYellow, we highly recommend utilizing the opt-in function to enhance the effectiveness of your email campaigns. While it is currently an optional feature, please note the following:

  • Complaints and Compliance: In the event that SendYellow receives complaints from recipients or email servers regarding campaigns sent by a user, SendYellow reserves the right to require the mandatory use of the opt-in function. This measure aims to ensure that email communications are consensual and compliant with industry regulations.
  • Refund Policy: If a user decides not to comply with the requirement of utilizing the opt-in function when it is mandated due to complaints or compliance concerns, SendYellow will not accept refund requests.


Standard support services are included for all product plans Monday - Friday from 8 am to 5 pm EST via chat or email. If you require a more advanced level of support, you can contact us to acquire an Enterprise Plan.


SendYellow Ltd. and its dedicated support team work hard to provide high-quality service that meets the needs of even the most demanding customers. This is why all of its infrastructure is hosted in the cloud with top-of-the-line services that include backup and redundancy. In addition, all our services are monitored by an Operations Center capable of quickly identifying any type of failure and executing the planned contingency plans. Despite all such efforts, you acknowledge that The Product may not be accessible for any reason related or not to SendYellow Ltd. and that refund requests related to service downtime will not be honored.

The product allows you to upload a list of contacts. Depending on the plan, it is allowed to upload one or more lists of contacts and the total number of contacts depends on each plan.
The contacts are the sum of subscribers and unsubscribers.
The number of contacts permitted in each plan is the sum total of contacts from all lists.

When you delete contacts from your contact list, the server may take time to make the deletion effective. It is possible that when you want to upload new contacts the system tells you that you have reached the limit of contacts. In this case, you must wait between 1 and 2 hours for the deletion to take effect.


Each plan has a maximum number of emails to send per month.

The same campaign sent to N contacts will be counted as N emails sent.

The user may not exceed the number of emails sent per month according to the subscribed plan.


The extent of your usage of The Product is dependent on your subscription plan. You shall not exceed the usage limits associated with your account. Unused amounts of emails sent will not carry over from one monthly period to the next. If you exceed your monthly usage limit.
The Product will return an error message indicating that your monthly usage limit has been reached and no more email can be sent within the current monthly window. It is your sole responsibility to ensure that your application(s) properly detect and handle any returned error messages. SendYellow Ltd. will make reasonable efforts to help you identify and resolve usage problems, or to review the suitability of your current subscription plan for your needs. SendYellow Ltd. reserves the right to limit or throttle the number of network calls available to Your application(s) if SendYellow Ltd.
