Usage Guidelines

Capsule requires that Affiliates use only the marketing materials available from the PartnerStack Platform. No re-sampling or other attempted duplication is allowed and no alterations, modifications, cropping or additions to the marketing materials or marks are permitted.

Any marketing materials or visual display for the Affiliate's products or services that use the “Capsule” trademark or logo must (in the sole opinion of Capsule) be consistent with the following brand attributes of the products and services offered by Capsule (e.g. easy-to-use, simple and powerful) and must comply with the Capsule Trademark Usage Guidelines.

Capsule has the right to review Affiliate’s use of the Capsule mark and marketing materials and Capsule may provide input about whether said materials or displays are compliant. If marketing materials or visual displays are, in the sole opinion of Capsule, inconsistent with the Capsule requirements, Capsule can require that such materials be changed prior to any public distribution as set forth in the Terms. If the Affiliate does not make the changes to its Site that Capsule deems necessary, Capsule reserves the right to terminate your participation in the Program.

In addition to the above, the appropriate ownership legend must be included in the “legal notices” section of any materials in which the “Capsule” logo or mark is displayed. This legend must read generally as follows: “Capsule is a registered mark, displayed with permission.” In advertising and promotional materials, the legend is typically placed at the bottom of the ad or layout. The legend may appear in small type, but must still be legible.

Unless authorized in writing from Capsule, Affiliate will not bid on or purchase keywords, search terms, or other identifiers, including the word Capsule, Zestia,, Capsule crm, any other trademark or brand name of Capsule or Zestia, or any variations or misspellings of any of these words (“Prohibited Keywords”) or otherwise receive any paid search results using the Prohibited Keywords. The Affiliate will enable negative keyword matching for all Protected Keywords, will not use Prohibited Keywords in any display URL content and may not direct link to a Capsule sales page from any paid advertising.

  • Using any illegal or spam method of advertising like unsolicited email, repeated placing of your referral link in forums, newsgroups, message boards, social media sites etc. We will not tolerate any form of spam or unsolicited email.

  • Targeting or placing advertisements on keywords and phrases containing our trademark, or variations or misspellings of the trademarked term. This means for example, that you may not bid on Pay per Click or Pay per Impression campaigns on any keywords or phrases containing our trademarks or registered URLs, or on any variations, abbreviations, or misspellings of the same.

Referral Fees

For the sale of a subscription to be eligible to earn a referral fee:

  • The customer must not have already visited the Capsule website via another source within the past 30 days;
  • And the customer must click-through a link from your site, email, or other communications to the Capsule website and sign up within 30 days of the initial click-through. If they fail to sign up within those 30 days and later return without following your link, you will not earn a referral fee

We will only pay referral fees on links that are automatically tracked and reported by our systems. For our systems to track the referral, the visitor must have cookies enabled. We will not pay referral fees if someone says they signed up through you but it was not tracked by our system.

The referral fee varies depending on the number of paying customers that you refer. This is 20%, 25% or 30% of our revenue from customers that you refer depending on the number of paying customers that you have secured. The referral fee will be credited to your Affiliate account when the customer pays their subscription. Although PartnerStack may track and calculate the commission accrued in accordance with the Program, determination of whether the subscription is eligible shall be made by Zestia.


Commissions will be paid by Zestia to PartnerStack and PartnerStack shall process and distribute commissions, less fees, in accordance with Your PartnerStack Terms of Use. Customer payments refunded or payments charged-back due to credit card fraud do not qualify for referral fees. We may delay crediting of referral fees subject to risk analysis considerations and Anti-Money Laundering procedures. Disputes regarding commissions or fees should be submitted in accordance with PartnerStack’s Terms of Use.

If fraud is detected, your account will be made inactive pending further investigation. In addition, in the event that you have already received payment for fraudulent activities, Zestia reserves the right to seek credit or remedy from future earnings or to demand reimbursement from you.

The referral fee structure is subject to change at our discretion.
