Best Email Platforms for SaaS Customer Advocacy Programs in 2026
An advocacy ask should follow evidence of value and give the customer a respectful choice.
Advocacy programs recruit reviewers, referrals, case-study participants, reference customers, community contributors, and beta advisors. Each action has different consent, eligibility, effort, and usage-rights requirements.
Evaluate product and account signals, role context, incentives, frequency caps, response suppression, approval, attribution, and the ability to stop an ask after participation. Measure completed advocacy actions with an explicit denominator rather than promising revenue impact.
