What is the best consent and preference management software in 2026?
The one that proves every visitor choice and lets customers control what they get, without breaking your email program. From $0 (Ketch, Usercentrics, Osano) to an enterprise quote (Didomi, OneTrust).
Consent management is really two jobs. The first is the cookie banner: it asks visitors for permission and stores proof of the answer. The second is the preference center: customers choose channels, topics and frequency, and those choices have to land in your CRM and email platform.
The short answer: Didomi is the best pick if you want both from one vendor, synced to HubSpot, Braze or Marketo, but you will need a quote. Usercentrics is the best value, with a banner from €7 a month and a Preference Manager you add later. Ketch includes a privacy preference center even on its free plan. iubenda is the cheapest way to prove newsletter opt-ins, and OneTrust is for enterprises with a privacy team.
Before you buy, check one thing: does your email platform already have a preference page? If you send from a single tool, a good banner plus that page is often enough. A dedicated preference platform earns its cost when customer choices must stay in sync across three or four systems.
The ranking is editorial: a sponsored placement is always labeled on its entry, and no affiliate link changes a score.

The full ranking. The "preference center" column tells you whether customers can set channels, topics or frequency with that vendor, and on what terms. Prices are the first paid plan on the vendor's own pricing page; "custom quote" means no figure is published.

How we compared and scored
For this search, the top five Google results are vendor blogs and software directories. The best-known list ranks its own publisher first and gives a price for almost none of the tools. We read each vendor's pricing and product pages, then public user reviews and practitioner discussions.
A tool makes the list if it collects and proves consent and either lets customers manage preferences or proves form opt-ins. Termly and consentmanager are not ranked: their banners are fine, but their official pages show no marketing preference management (channels, topics, frequency). Termly's preference center only covers cookies.
Web consent and preferences carry the most weight because they are the two halves of the question. Pricing comes next, since most of these tools keep part of their pricing behind a quote. Setup effort and scale break the remaining ties.
- Web consentBanner, proof of choice, reject as easy as accept, TCF.25%
- Preferences and syncChannels, topics, frequency, sync to CRM and email.25%
- Pricing clarityPublished prices, free plan, clear billing meter.20%

The ranking is editorial: a sponsored placement is always labeled on its entry, and no affiliate link changes a score.
Didomi
Didomi is a French vendor with two products that fit together. The CMP (consent management platform) collects each visitor's cookie choice and keeps proof of it. The PMP (preference management platform) handles everything after that: your customer picks channels, topics and how often they hear from you, through a full-page preference center, an embedded form or a small widget.
Those choices flow natively into Braze, Marketo, Pardot and HubSpot, and through an API into everything else. So when a customer ticks "monthly digest only" in their account, your email platform applies it without anyone exporting a CSV.
The catch is pricing: nothing is published. The CMP is billed on monthly unique visitors with unlimited domains, which favors groups running many sites. Essential and Advanced scan your cookies monthly, Premium weekly. There is no free plan and no trial on the page.
- Consent and preference center from one vendor
- Native sync to Braze, Marketo, Pardot, HubSpot
- Unlimited domains, billed per unique visitor
- ✓Deepest preference center in this ranking
- ✓Banner and preferences share one proof store
- ✓Built for many brands and many countries
- ✗No published price, not even for the CMP
- ✗No trial and no free plan
- ✗Overkill for a brochure site
The pick when your marketing team already sends segmented email and needs every partial opt-out respected across tools. Ask for the PMP price as its own line, separate from the CMP.
Usercentrics
Usercentrics is a German vendor that also owns Cookiebot. Its CMP has the longest public price ladder here: free under 1,000 sessions a month, €7 a month up to 1,500 sessions, €30 for 15,000 sessions across 3 domains, €50 for 50,000 across 10, then steps up to one million sessions. The 14-day trial needs no card. Prices are listed in euros, so a US buyer pays the exchange rate.
Preference Manager is a separate product. Customers manage their communication preferences on your site, at signup or in your app. Updates leave through webhooks, and into Mailchimp through a Zapier connector. That is lighter than Didomi: no native CRM connector is front and center. No price is published, but the trial runs 30 days.
One thing to watch: the CMP counts sessions, not visitors. A content site with lots of short visits climbs tiers faster than you expect. Pull last month's sessions from your analytics before you pick a plan.
- Public price ladder from €7 to €750 a month
- 14-day trial, no card
- Preference Manager with webhooks
- ✓Free start, then gradual tiers
- ✓Several domains from the Pro plan
- ✓One vendor for banner and preferences
- ✗Preference Manager is quote-only
- ✗Few native CRM connectors
- ✗Billed per session, which adds up faster
The sensible middle ground: a banner with a public price now, and a preference center you can bolt on once your email list grows.
Ketch
Ketch is a US vendor with an unusual offer: its privacy preference center ships on every plan, free included. The Free plan is not a trial. It stays free while you stay under 5,000 monthly unique users, with two integrations and email support, and no credit card to start.
The next step is steep. Starter costs $150 a month on monthly billing for up to 30,000 users, and Plus starts at $499 a month billed annually. Marketing preference management (channels, topics, frequency), data mapping and DSR automation are priced separately or bundled into the custom Pro plan. So the free tier covers privacy choices, not your whole email relationship.
It is the most natural fit in this list for a US company: pricing in dollars, published tiers up to Plus, and an easy path from free to paid. Just budget for the jump from $0 to $150.
- Preference center included even on Free
- Free up to 5,000 monthly unique users
- No credit card to start
- ✓Most useful free tier for preferences
- ✓Published prices up to Plus
- ✓Free plan with no time limit
- ✗Jump from $0 to $150 a month
- ✗Marketing preferences are an add-on
- ✗DSR automation only on Pro or as an add-on
Start here if you run a SaaS with modest traffic: you get a real preference center for free and already know what the next tier costs.
iubenda
iubenda is an Italian vendor selling a legal toolkit: cookie banner, privacy policy and terms generator, and a consent log. That log, the Consent Database, records what happened in your forms: who ticked the newsletter box, when, and which wording they saw.
That is exactly what you need when someone claims they never signed up. Cookie consent proof is included in all three plans. Form consent proof costs €5 a month per 1,000 consents (the page lists it in euros only). Essentials starts at $5.99 per site a month on a yearly plan, with 25,000 pageviews, and the page lists overage per extra 1,000 pageviews.
Its limit: it is not a preference center. Your customers do not pick topics or frequency in iubenda. You prove consent there, and let your email platform handle preferences.
- Proof of form consents
- Generated legal policies
- From $5.99 per site a month
- ✓Cheapest route to full opt-in proof
- ✓Banner and legal pages in one plan
- ✓14 days to get a refund
- ✗No preference center
- ✗Billed per site
- ✗Pageview overage is extra
Right for a small business that mainly needs to prove opt-ins. Once you segment your sends, you will want a real preference center on top.
Osano
Osano is a US vendor. Its banner is free up to 5,000 visitors a month on one domain. Plus, at $199 a month, covers 30,000 visitors, 3 domains and 2 users, and includes a UK and EU representative, which matters if you sell into Europe without an office there.
The Unified Consent & Preference Hub adds a customer-facing preference center, and Basic Privacy adds subject rights requests. Both are quote-only. There is no tier between free and $199 a month, which hurts a small team that outgrows the free plan.
For a single small site, Ketch or iubenda cost less at the same traffic. Osano earns its place when one legal team runs privacy for many sites and wants a single vendor.
- Free up to 5,000 visitors
- UK and EU representative on Plus
- Preference center in the hub
- ✓One dashboard for banner, preferences and rights
- ✓Useful free plan for a small site
- ✓Built for multi-law programs
- ✗Nothing between $0 and $199
- ✗Preference hub on quote
- ✗Thin public detail on the hub
Worth a demo if one legal team owns privacy across many properties. For a single small site, the $199 step is hard to justify.
OneTrust
OneTrust is one of the best-known privacy software vendors. Its Universal Consent & Preference Management module gives customers one portal for consent, communication preferences and the first-party data they share with you. It ships with pre-built integrations for Salesforce, Marketo, Snowflake and Adobe.
It is powerful, but it is a separate product from cookie consent, and nothing is published: no price, no trial. Budget like an enterprise buyer. User reviews describe months of setup, steep renewal increases and a banner that slows pages down.
If you sign, get a cap on annual increases and bulk export of consent records written into the contract. If not, our OneTrust alternatives page lists lighter options.
- Salesforce, Marketo, Snowflake, Adobe integrations
- One portal for consent, preferences and customer data
- Covers many privacy laws
- ✓Most complete option for a large group
- ✓Preferences tied to first-party data
- ✓Modules you switch on as needed
- ✗No published price or trial
- ✗Long implementation
- ✗Renewal increases are a common complaint
Only if you have a dedicated privacy team. Everyone else gets the same job done with Didomi or Ketch, faster.
Banner, proof or preference center: what do you need?
Three different needs hide behind "consent management". Plenty of teams pay for a preference platform when a banner and their email tool's preference page would do. Others do the reverse and cannot prove an opt-in when a complaint lands.
A cookie banner (CMP)
Opt-in proof
A preference center (PMP)
- List your sending tools: one, or several?
- Check whether your email platform already has a preference page.
- Make sure your banner offers "Reject all" on the first layer for EU visitors.
- Ask how an unsubscribe made in your email tool syncs back to the PMP.
- Export a consent log during the trial.
Visitors, sessions or pageviews: what you actually pay
Pricing pages do not count the same thing. The same site can fit a free plan with one vendor and pay $150 a month with another. Pull last month's numbers before you compare.
Per unique visitor
Per session
Per pageview
- Pull unique visitors, sessions and pageviews for last month.
- Work out your real tier with each vendor, not the headline price.
- Ask for the PMP price as a separate line from the CMP.
- Get a cap on renewal increases in writing.
- Count every domain and subdomain you need to cover.
Six checks before you sign
What separates a preference center people use from one more form nobody opens, according to teams that have rolled one out.
Open your email platform's preference page first
BudgetMailjet, like many sending tools, ships a no-code preference page. If you send from one tool, switch it on and add topic-based lists. Buy a PMP only when that page stops being enough, for example when SMS or your app join the loop.
- Cost
- often included
Keep one-click unsubscribe
DeliverabilitySince 2024, Gmail requires senders of more than 5,000 messages a day to support one-click unsubscribe and show a visible link. Never hide that link behind your preference center. Put both side by side: "Get fewer emails" and "Unsubscribe". A frustrated reader who hits "spam" costs you more than one who leaves.
- Gmail threshold
- 5,000 messages a day
- Spam rate
- below 0.30%
Test sync in both directions
CRMDuring the demo, unsubscribe a contact in your email platform and check that the PMP shows them as opted out. Then do the reverse. If only one direction works, you will end up with two versions of the truth and, sooner or later, email someone who said no.
- Check
- email to PMP, and back
Give "Reject all" the same weight as "Accept all"
EU trafficFrance's CNIL and Spain's AEPD both expect refusing to be as easy as accepting. If you get EU traffic, put both buttons on the first layer, same size and style, and keep a "Cookie settings" link in the footer so people can change their mind at any time.
- Rule
- same effort to refuse
Export a consent log during the trial
AuditA consent log only helps if you can get it out. During the trial, accept and reject from two browsers, then export the log. If bulk export is not included in your plan, get it written into the contract before you sign.
- Cases to replay
- accept, reject, withdraw
Offer three to five topics, not fifteen
ConversionA preference center with fifteen checkboxes scares people off. Start with three to five clear topics (product news, offers, content) and a frequency choice (weekly, monthly). Add topics when your sends justify them, and make sure each topic maps to a real list in your email platform.
- Good start
- 3 to 5 topics

Consent and preference management · FAQ
What is the difference between a CMP and a preference management platform?
A CMP handles cookie consent on your site and stores proof of it. A preference management platform (PMP) handles what customers want to receive: channels, topics, frequency. Didomi, Usercentrics, Ketch, Osano and OneTrust sell both, almost always as two separately priced products.Is my email platform's preference page enough?
Often, yes, if you send from one tool. Mailjet, for example, ships a no-code preference page inside its suite. A PMP pays off when preferences have to live in several systems at once: CRM, email, SMS and your app.Is there free consent and preference management software?
Yes. Ketch includes a privacy preference center on its Free plan, up to 5,000 monthly unique users. Usercentrics is free under 1,000 sessions, Osano under 5,000 visitors, but those two free tiers mostly cover the banner.Can a preference center replace the unsubscribe link?
No. Since 2024, Gmail requires senders of more than 5,000 messages a day to support one-click unsubscribe and show a visible unsubscribe link. Keep that link, and offer the preference center next to it as a softer option than leaving entirely.How do consent tools price their plans?
Each vendor counts something different. Didomi, Ketch and Osano count unique visitors, Usercentrics counts sessions, iubenda counts pageviews. Pull last month's numbers from your analytics and work out the exact tier with each vendor before comparing.How long should I keep consent records?
For as long as you rely on that consent, plus enough time to defend yourself in a dispute. France's CNIL, for one, expects you to be able to prove every consent, and lists dated screenshots of the banner and timestamped records of your consent platform's successive configurations among acceptable evidence. Check that your tool can export that full history before you cancel a contract.Can someone who unsubscribed opt back in from the preference center?
It depends on the tool. Some email platforms block re-subscribing once consent is withdrawn. Test this during the trial: a returning customer should be able to give fresh, timestamped consent while the old opt-out stays on record.Do I need a European tool if I only sell in the US?
Not necessarily. Ketch and Osano are US vendors priced in dollars. A European vendor like Didomi or Usercentrics makes more sense once you have real EU traffic, where a reject button as easy as accept and stored proof become the baseline.
