Our verdict on Thermostat
Thermostat measures customer sentiment through one-question Net Promoter Score and CSAT surveys. It is designed for small businesses and SaaS or ecommerce teams that need email campaigns, embedded website or app surveys, shareable links, or API-based collection. Results can be reviewed in reporting dashboards, filtered by dates and custom respondent fields, and compared across segments. Feedback replies, score-based messaging, and scheduled daily or weekly snapshot emails extend the product beyond basic score collection.
The published plans cover a clear progression. Free costs $0 per month and includes 1 user, 1 survey, and free-forever access. Pro costs $49 per month and adds 5 surveys, email, embed, link, and API administration, plus forever response history. Premium costs $99 per month and expands the allowance to 5 users and 20 surveys while retaining those administration options and response history. Enterprise costs $199 per month, supports 25 users and 50 surveys, and adds priority email and phone support. The free plan has a 2,000-response limit, while paid tiers provide a path to broader survey administration.
Thermostat’s web and API access suits teams that want to connect survey collection to their own workflows. Its JSON API supports sending surveys and retrieving results, while integrations include Stripe, Mailchimp, ConvertKit, Drip, Zapier, and Salesforce. Custom fields support segmentation, and replies plus score-based messaging provide follow-up capabilities. Choose Thermostat for focused NPS and CSAT programs that value multiple delivery channels and API access. Teams needing more advanced workflows or a wider integration ecosystem should consider a broader alternative.
