Thermostat

Thermostat is an NPS-focused survey service for teams that need customer sentiment collection across email, web, links, or an API. It fits product, customer-success, and marketing groups that rely on segmentation and branded surveys more than broad form-building. Its strongest case is structured NPS analysis and feedback follow-up; the main constraint is the sharp increase in survey, seat, volume, and history limits between plans.

Overview

Thermostat centers each survey on one question, with an optional comment field and anonymous responses when appropriate. Distribution is flexible: send by email, place a popup in a site or product, share a standalone link, or integrate sending through the API. That range suits teams running the same NPS program across several customer touchpoints.

Its reporting is designed for the Net Promoter System, including filters, comparisons, and customer-satisfaction views. Custom fields accept text, numbers, dates, and lists, letting teams break scores down by their own customer attributes instead of relying only on the rating. Feedback can be filtered, starred, and answered, and daily or weekly email updates surface score and comment changes without requiring constant dashboard visits.

Key features

Delivery and integrations

Direct campaign integrations include Stripe, Mailchimp, ConvertKit, and Drip, with Zapier connections also described. The API can send surveys and retrieve results programmatically, which is useful when NPS belongs inside an existing product or data workflow rather than a separate campaign routine.

Branding and follow-up

Logos and colors can be applied to survey emails, pages, and embedded popups, helping a survey match the surrounding customer experience. Email updates are available daily or weekly. Together with filtering, starring, and replies, that creates a focused feedback-handling loop, though it remains narrower than a full customer-support or case-management system.

Support and scale

Email support is included on every plan, priority email support comes with paid plans, and Enterprise adds phone support. Plans are offered up to 80,000 surveys per month; organizations above that level are directed to contact the company.

Pricing

The free tier is genuinely permanent, but one survey, 200 administered surveys per month, and four months of history make it a pilot tier rather than a durable archive for an active program. Pro keeps one seat while raising the survey and volume ceilings and removing the history expiry. Premium is the practical step for a team, adding four more users and substantially higher quotas. Enterprise is aimed at departments with many operators and still larger campaign volume. There is no free trial, while paid purchases carry a 30-day money-back guarantee. The service is freemium, with paid plans starting at $49/mo.

Platforms

Thermostat is offered through the web and an API. The API emphasis matters for teams embedding survey delivery and result retrieval in their own systems; there is no separate mobile platform listed.

Who it's for

Choose Thermostat if your program is specifically NPS-oriented, needs custom-field segmentation, and uses several collection channels or API automation. The paid tiers make the most sense when permanent response history, higher monthly administration, or multiple users matter. The free plan suits a small proof of concept. It is less suitable for teams seeking a broad questionnaire builder, generous no-cost response quotas, or a fully featured support workspace.

Pros and cons

Pros

• Purpose-built NPS reporting: filters, comparisons, and satisfaction views keep analysis focused on Net Promoter work.
• Flexible collection: email, popups, links, and API delivery cover common product and campaign workflows.
• Useful segmentation: text, number, date, and list fields connect scores to customer attributes.
• Branded feedback experience: logos and colors can be applied across emails, pages, and popups.
• Permanent history on paid plans: Pro and above avoid the Free tier's four-month archive limit.

Cons

• Free limits are restrictive: one survey and 200 administered surveys per month leave little room for a mature program.
• Seats and quotas jump by tier: Pro remains one-user, while collaboration starts at Premium's $99 monthly price.
• No trial period: prospective paid users must rely on the free tier or the 30-day money-back guarantee.

Alternatives

Net Promoter Score Software is the broader category list for comparing NPS-focused tools.

• Formbricks is the better direction if self-hosting, mobile access, or a 250-response Hobby plan matters; its Pro plan is $89 per month.
• Fynzo Survey suits users prioritizing broad survey creation, with a free plan advertising unlimited surveys, questions, and responses.
• Refiner is an alternative for teams wanting a free tier after trial with 25 survey responses per month.
• SatisMeter is worth comparing when a dedicated NPS product with a $199-per-month Growth plan fits your budget.
• Mapster is a lower-cost web option: its free plan allows 50 responses per month and unlimited surveys.
• Survicate is another freemium choice with a free plan capped at 25 responses per month and three teammates.
• Customer Thermometer is a paid alternative with plans starting at $9 per month.
• Zonka Feedback is an option for teams evaluating feedback-management offerings with custom-quoted pricing.

Verdict

Thermostat is a good choice for teams that want NPS collection, customer-attribute segmentation, and lightweight feedback handling in one focused service. Its API, channel variety, and permanent paid-plan history strengthen the case for an embedded or recurring program. Look elsewhere if your priority is a generous free quota, many collaborators at entry pricing, or a general-purpose survey and support platform.
