An excerpt regarding your obligations can be found below:
In no event will Affiliate engage in any Affiliate Marketing Activities except as expressly set forth in this Agreement. In the event that Affiliate has a list of emails where the individuals on the list have expressly elected to receive emails from Affiliate (“Opt-in List”), Affiliate may make a written request to Sonetel to send emails regarding the offering of Sonetel to the individuals on the Opt-in List (and Sonetel may, in its sole discretion, allow Affiliate to send such emails). In conducting all Affiliate Marketing Activities, Affiliate will comply with all applicable laws, rules, regulations and directives, including but not limited to those relating to email marketing and “spamming”. Unless Affiliate has secured the applicable Referred Customer’s consent first, Affiliate will not email any Referred Customer whose email address they have received via Sonetel.
Without limiting the generality of the above clause, Affiliate will (i) not send any email regarding Sonetel to any individual or entity that has not requested such information; (ii) always include Affiliate’s contact information and “unsubscribe” information in any email regarding Sonetel or the Service; and (iii) not imply that such emails are being sent on behalf of Sonetel.
An Affiliate will not (i) engage in any fax, broadcast, telemarketing or any other offline marketing methods with respect to Sonetel; (ii) use malware, spyware or any other aggressive advertising or marketing methods in any of its dealings relating to Sonetel; (iii) make any false, misleading or disparaging representations or statements with respect to Sonetel; (iv) solicit Referred Customers to leave the Sonetel Service; (v) copy, resemble or mirror the look and feel of Sonetel’s websites, Sonetel Trademarks or Services or otherwise misrepresent Affiliate’s affiliation with Sonetel; or (vi) engage in any other practices which may adversely affect the credibility or reputation of Sonetel, including but not limited to, sending email communications or using any Website in any manner, or having any content on any Website, that (a) uses aggressive or low-quality marketing, including marketing services that are unrelated to Sonetel or the Affiliate’s services, (b) promotes sexually explicit materials, violence, discrimination based on race, sex, religion, nationality, disability, sexual orientation or age, or any illegal or objectionable activities, or (c) violates any intellectual property or other proprietary rights of any third party; or (d) violates the Terms & Conditions.
An Affiliate will not promote or advertise Sonetel on coupon, deal, or discount sites or on GTP/Get Paid to Click or other incentivized sites, or display any offer code on a public-facing page or through the use of a “click to display” offer code;
use its Affiliate Link directly in any pay-per-click advertising;
purchase search engine or other pay-per-click keywords (such as Google Ads), trademarks or domain names that use the Sonetel Trademarks or any variations or misspellings thereof that may be deceptively or confusingly similar to the Sonetel Trademarks;
create or participate in any third party networks or sub-affiliate networks without the express written permission of Sonetel;
use or encourage any means of delivering fraudulent traffic, including but not limited to use of bots or toolbar traffic, cookie stuffing, or use of false or misleading links;
use direct linking to any page on any Sonetel website, without prior written permission from Sonetel; or
mask its referral sites or use deceptive redirecting links.
The Federal Trade Commission in the United States (“FTC”) has guidelines for governing endorsements and testimonials. These rules are aimed at increasing transparency between endorsers and consumers. As a member of the Affiliate Program with Sonetel, Affiliate receives compensation for the Referred Customer referrals made to Sonetel. This may establish a “material connection” according to FTC rules, which creates an obligation for Affiliate to provide disclosure to consumers. Full compliance with these guidelines requires, among other things, that (a) Affiliate clearly and conspicuously disclose that Affiliate is being compensated for referring Referred Customers to Sonetel, and (b) Affiliate not engage in misleading or deceptive advertising. For further information Affiliate should refer to the statement released by the FTC regarding these guidelines.
A Referred Customer cannot be owned or controlled by an Affiliate. An Affiliate will be deemed to have introduced only those Referred Customers that: access Sonetel from that Affiliate’s Affiliate Link assigned by Sonetel.
