Recognisable sender addresses and branded reward pages can help research teams make incentive delivery more trustworthy, according to TruCentive guidance published on May 9, 2026. The company warns that an unexpected reward email from an unfamiliar sender can undermine the experience even after a participant has completed a study.

The company claims that 80% of users will flag an unfamiliar email as suspicious on first glance, and known senders receive 63% more clicks than unknown ones. TruCentive advises that reward emails should originate from a subdomain controlled by the company, rather than a generic platform address.

TruCentive offers full design control for the claim page, where participants can select their Visa prepaid card, merchant gift card, or swag item. The company recommends that the claim page should carry the company's logo, color palette, and voice to create a seamless experience.

The company also emphasizes the importance of integrating the incentive platform with the recruiting tool or CRM to automate reward delivery and reduce operational burden. TruCentive notes that virtual prepaid cards are most common, but many audiences prefer merchant gift cards, which work especially well when the company knows the audience's preferences.

TruCentive advises that the email notifying participants of their reward should use the company's tone, acknowledge the specific contribution, and include the standard email design template. The company also recommends that participants should know before a session begins what they will receive, when, and in what form, to create clarity and transparency.

The company notes that many incentive platforms profit from breakage, with roughly 20% of value going unclaimed globally. TruCentive recommends looking for platforms that return unclaimed balances to the company's account. According to the company, neuroscience research shows that a 24-hour gap between the expectation of a reward and its delivery can trigger loss aversion, which can negatively impact participant experience.

TruCentive recommends that companies evaluate incentive delivery platforms based on several factors, including the ability to send from the company's domain, fully branded claim experience, integration with the tech stack, and the ability to send reminders and control email content and design. The company claims that teams that get this right report measurable improvements in panel health, including higher return rates and stronger referral numbers.
