Seamless.ai Review (2026)No Published Price Above Free
By Daan Haket · Tested hands-on · written with an AI assistant · who does what
Data accuracy is the recurring complaint: independent tests put email deliverability around 74% (20–30% bounce) versus ZoomInfo's ~2–3%, so real cost per usable contact climbs. The tool we compare it with at each step below is ZoomInfo.
- Best for Outbound teams building large prospect lists
- Not for teams where data accuracy comes first

Tested by our team on 31 October 2026 with the free credits: Daan created the account and our AI assistant ran the test in Daan's browser. We searched the company database for two of our own sites and one well-known company, without spending credits or revealing any contact details.
How we tested
- Searched the company database for two of our own domains
- Ran one control search on a well-known domain
- Checked the credit counter before and after
- The account came with 50 free credits and no card. After logging in it asked for phone verification.
- The setup filters preselect the United States and Canada as locations; we skipped them.
- A company search for AI Builder Marketplace and for Marketing and Sales Software found neither.
Pricing (2026)
✓ Pricing re-verified 30 Sep 2026
| Plan | Price | What you get |
|---|---|---|
| Free | no published price | 50 Universal Credits that do not replenish |
| Basic | no published price | 250 Universal Credits a month, refreshing on contract date |
| Pro | no published price | 10,000 Universal Credits a month, refreshing on contract date |
Summarised from the pricing notes below; the notes carry the conditions.
The pricing page no longer shows plans: seamless.ai/pricing now forwards the browser to seamless.ai/pricing-inquiry, a demo-request form headed 'Perfect Pricing for Startups to the Fortune 500' that offers special pricing for unlimited users, bulk credits, prospector, job changes, buyer intent and enrichment, and carries no amount, no plan table and no FAQ. Still no published price above the free plan, in a fifth reading.
Seamless's help centre now states the allowances: Free is 50 Universal Credits that do not replenish; a Basic licence gets 250 Universal Credits a month and a Pro licence 10,000 a month, both refreshing on the contract date; bulk pool credits are bought up front and do not replenish. Legacy Pro accounts created before 1 April 2026 keep 1,000 credits a day, no longer sold.
Full pricing notes (2 more paragraphs)
Researching a contact costs 1 credit for the whole profile, a Data Enrich row 1, an Autopilot contact 1, and an AI Assistant interaction or AI-written message 0.2. Buyer Intent runs on separate Intent Topics, not credits. Credit Back Protection refunds the credit when Seamless's own check flags an email as invalid, but not for soft bounces, role addresses like info@, or phone numbers.
Until 7 September the pricing page's FAQ said Pro starts at 10,000 annual credits; the help article says 10,000 a month, so ask which one your quote uses. Third-party guides report an entry around $147 a month for roughly 250 credits; that matches the Basic allowance, but the dollar figure is not Seamless's number.
Plans change, so check the live price on their site before you buy.
Category context: Growth & Revenue. Across the 84 tools in this category that we researched with a public US-dollar price, the median entry price is about $30 a month (lowest paid plan as listed, per seat where the vendor prices per seat). Compare pricing conditions in the Software Cost Atlas →
What the price did
We read Seamless.ai’s own pricing page on a schedule and keep every reading, so this is our record of the page. It is not a forecast, and not someone else’s summary. A change appears here only after we confirmed the new price on the page itself.
No series, and no published price to build one from: our July and August 2026 captures both contain no amount, there was still no public rate card on 17 August 2026, and there is none on 7 September 2026 either. Four readings, four blanks. The one thing that has appeared is a quantity: the FAQ's floor of 10,000 annual credits on Pro. Any money figure you find for this tool came from a buyer or a comparison site, not from Seamless. On 30 September 2026 the pricing page itself was gone: seamless.ai/pricing forwards to a demo-request form with no plans and no amounts. Five readings, five blanks. The quantities moved to the help centre instead: 250 Universal Credits a month on Basic, 10,000 a month on Pro, after a June 2026 migration of all legacy Standard and premium credits into Universal Credits.
What the pricing page doesn’t say
The buying experience is the other weak spot: sales-led, auto-renew with 30–60 day written cancellation, and reports of charges after a 'confirmed' cancellation.

What Seamless.ai does
B2B contact database with AI list-building, plus an MCP server so Claude or ChatGPT can run the searching and enrichment. Nothing above the free plan (1 user, 50 credits) carries a published price; the only quantity their FAQ names is a Pro floor of 10,000 annual credits. Independent tests put deliverability near 74%, and contracts auto-renew with 30-60 days' notice to cancel.
What buyers report about Seamless.ai
Hands-on: tested 2026-10-31Reported by buyers: G2, Capterra, Trustpilot, Reddit and the BBB, read August 2026
Themes from the buyer-review sites listed at the foot of this page, read in August 2026. We tested Seamless.ai ourselves on 2026-10-31, but one test is a narrow sample, so here is what other buyers report. We summarise it here because the complaints are usually the part a vendor page leaves out.
- • Real-time search rather than a static database, and the Chrome extension pulls contacts while you browse: 4.4 on G2 across 5,000+ reviews, 4.5 on Capterra.
- • Reviewers who work within their credits report it finding contacts other tools miss.
- • Cancellation is the number one complaint across every platform: ahead of data quality, pricing and features. Contracts are annual with 60 days' notice required before renewal; miss it by a fortnight and you have another twelve months.
- • One reviewer submitted cancellation three months early, had it acknowledged, was charged anyway, and needed four months plus a credit card dispute to resolve it.
- • Bounced emails and disconnected numbers still consume your credit. There are no refunds for invalid data.
- • Renewal often pairs a price increase with a reduced credit allotment.
Where the ratings disagree. 4.4 on G2 against 1.4 on Trustpilot, and the BBB logged 79 complaints in three years with 42 never answered. That is the widest and best-documented split in this whole set. The G2 reviews are about finding contacts; the rest are about getting out.
Pages read (August 2026): Trustpilot
Price the usable contacts, not the credits
There is still no published price above the free plan, and since late September 2026 there is not even a pricing page: seamless.ai/pricing now forwards to a demo-request form that promises special pricing and shows no amount (read 30 September 2026). Five readings across July, August and September, five blanks. Free is one user and 50 credits that do not replenish; everything above it is Contact sales. What Seamless does publish is the allowance, in its help centre rather than on a sales page: a Basic licence gets 250 Universal Credits a month and a Pro licence 10,000 a month, both refreshing on the contract date.
That explains the figure everyone else quotes. Third-party guides report an entry around $147 a month for roughly 250 credits, which is the Basic allowance, not Pro. Moving from Basic to Pro is a 40-fold jump in credits, so the real question is whether you will research more than 250 contacts a month. One conflict remains: the old pricing page's FAQ, read on 7 September, put the Pro floor at 10,000 annual credits, not monthly.
That is a twelve-fold difference; get it in writing. What a bigger tier does not buy is the extras. On 7 September the old page marked AI Assistant, Data Enrichment, Autopilot and Buyer Intent Data as Add-on in every column, Enterprise included. The help centre now says the first three draw on the same Universal Credits, while Buyer Intent needs separate Intent Topics. Either way, upgrading the tier is not what puts intent data in the contract.
What the contract rations is credits, not seats, and a credit here buys the whole profile, phone number and email together. So the number to compare is not the price per credit but the price per contact you can actually reach. Independent tests put email deliverability here around 74%, meaning 20-30% bounce, against ZoomInfo's roughly 2-3%. Credit Back Protection refunds the credit when Seamless's own check flags an email as invalid, but not soft bounces, role addresses or phone numbers, so it trims that gap rather than closing it.
Divide any per-credit rate you are quoted by your own measured hit rate before you compare it with anything, and take that measurement during the free 50 rather than trusting either figure. The other half of this purchase is the paperwork, and it is where the complaints cluster. The contract auto-renews and requires 30 to 60 days' written cancellation; buyers report the renewal conversation being harder than the first sale, and there are reports of charges landing after a cancellation the customer believed was confirmed.
None of that is a price, but all of it is a cost. Get the notice period, the cancellation method and the renewal price in writing, and put a calendar reminder 90 days before renewal on the day you sign, not 30, because 30 is the window itself.
What we found running Seamless.ai ourselves
The first findings are at the top of this page. The rest:
- A control search for hubspot.com found it, but the phone numbers and description stay blurred until you click 'Find', which costs credits.
- Searching did not use any credits.
Claim vs. what we measured
We set a claim from Seamless.ai's own pages next to what we saw in our test, on the plan named. The status says whether the two describe the same thing and match; it is not a verdict on the product. Confirmations are listed too.

Exit test: can you take your data out?
Company-domain search; CRM kit used only as an evaluation matrix. Test date: 31 Oct 2026. We describe the friction rather than score it; this is one run with synthetic records, not a verdict on Seamless.ai.
| What we checked | What we saw |
|---|---|
| Fields offered by the export dialog | |
| Not offered in the field selector | None noted. |
| The exported file | We did not inspect the file, so data retention and loss remain unverified. |
| Awkward but not lost | Login was followed by phone verification handled by the account owner. Onboarding preselected United States and Canada in the location filters; we skipped this step, and do not infer the effective search geography. Both our own domains returned zero matches with the observed Default company matching. The hubspot.com control returned one result, with Company Phones and About blurred behind Find. We did not reveal fields or spend credits: the balance stayed at fifty. In our two dated tests Apollo found aibuildermarketplace.com and did not find marketingandsalessoftware.com; Seamless found neither. This limited comparison does not establish broader database coverage. No kit contacts were entered, no export obtained, no mailbox connected and no prices inspected. |
| Export route | No own records; export not tested. |
| Export format | No export file obtained. |
| Re-importing the export | No application record reimport tested. |
| Cancelling | No cancellation, expiry or deletion action tested. |
What the exit test does not show:
- Complete signup screen count and human first-result setup speed.
- Actual cancellation, expiry, deletion and follow-up mail.
- Kit fields not entered and application record reimport.

- Contacting support
Most of our reviews are researched rather than run. How we review explains which is which, and why we do not pretend otherwise.
How to actually use Seamless.ai
Spend the 50 free credits as a measurement rather than a trial. Pull 50 contacts you can verify independently (people at companies you already sell to, or addresses you have mailed before) and check two things: how many resolve at all, and how many actually deliver. Independent tests put deliverability here around 74%, and your own 50 will tell you whether your segment is better or worse than that. Take that bounce rate into the sales conversation, because it is the only number that converts their price into your cost.
Divide any quoted per-credit rate by your measured hit rate and compare that figure, not the quoted one, against the alternatives. Go into that conversation with the one quantity they do publish. Their FAQ says Pro starts at 10,000 annual credits, so ask what those 10,000 cost before you discuss anything bigger, and ask separately about the AI Assistant, Data Enrichment, Autopilot and Buyer Intent Data, which are add-ons on every tier including Enterprise.
Then handle the contract before the product. Ask for the renewal price, the notice period and the cancellation method in writing, and set a calendar reminder 90 days before each renewal date at the moment you sign. The notice window is 30 to 60 days, so a reminder set at 30 days is already too late, and buyers report the exit being harder than the entry.
Where this section comes from: our research notes (283 words)
On 30 September 2026 seamless.ai/pricing served only a script that forwards to seamless.ai/pricing-inquiry (page source, last published 29 September 2026); that form was read in full and carries no amount, plan table or FAQ. Allowances and credit costs come from Seamless's help-centre articles 'Seamless Credit and License Types' and 'Credit Back Protection' (seamless.ai/customers/education/articles/), plus seamless.ai/products/bulk-credits, all read 30 September 2026. seamless.ai/llms.txt, read the same day, still carries no amounts. Earlier reading: seamless.ai/pricing read on 7 September 2026, plus seamless.ai/llms.txt the same day.
The pricing page is served complete as HTML, no browser needed, and no amount appears anywhere in it. The plan columns (Free / Pro / Enterprise) were read cell by cell down the full feature list, which is where the four Add-on markers (AI Assistant, Data Enrichment, Autopilot, Buyer Intent Data) and the Pro card's '1 Credits = Phone + Email' come from. The only number above Free is in the FAQ block at the foot of the page, which is also published as FAQPage JSON-LD in the same document: 'Pro plans start off at 10,000 annual credits', no setup fees, and the answer claiming the prices shown reflect the annual discount.
seamless.ai/llms.txt says subscriptions are tiered by features, seats and usage, that credit consumption depends on plan, and instructs AI systems reading it: 'Do not invent pricing, availability, or guarantees.' It carries no amounts either. Note on what was NOT re-checked in this reading: the ~74% deliverability figure and the auto-renewal and cancellation reports are third-party and buyer-reported, not vendor-published, and they were carried over from earlier rounds rather than re-sourced today.

Seamless.ai vs ZoomInfo, side by side
Where a vendor publishes a price, its column shows the entry price we read and when; where it does not, the column says so rather than filling in a figure from elsewhere. We do not average them into a score.
Both names above are affiliate links: we may earn a commission if you sign up, at no extra cost to you. Neither changes what this table says.
The natural comparison is ZoomInfo or Apollo: the more accurate and the cheaper data tools. Weigh it against ZoomInfo on the job you actually need done.
Not a fit for you?
Seamless.ai is not the pick for teams where data accuracy comes first. In that case, look at ZoomInfo, built for enterprise go-to-market teams that need the deepest US database, buyer-intent signals and conversation intelligence, and can absorb the contract.
The Visit link is an affiliate link: we may earn a commission, at no extra cost to you. We picked this alternative for fit first; commission only decides between equal fits.
Frequently asked questions
Can you export your data from Seamless.ai?
Exit check 2026-10-31; route excerpt: No own records; came along (excerpts): not tested; lost (excerpts): not tested; re-import: not tested.
What does Seamless.ai cost?
It is not published, and the pricing page now forwards to a demo-request form. There is a free plan with one user and 50 credits that do not replenish; everything above it is quoted by sales. Seamless's help centre gives the allowances: 250 Universal Credits a month on a Basic licence, 10,000 a month on Pro. Third-party guides cite roughly $147 a month for about 250 credits, which fits Basic, but we could not verify any amount against Seamless's own pages in five readings.
What should I check before signing?
The credit allowance and what happens when it runs out, since that is what the contract rations, and which of the four add-ons you need: AI Assistant, Data Enrichment, Autopilot and Buyer Intent Data were marked Add-on on every tier, Enterprise included, when the pricing page still listed plans (7 September 2026); Buyer Intent also runs on separate Intent Topics rather than credits. Buyers also consistently report friction at renewal rather than at purchase, so get the cancellation terms and the renewal price in writing at the start.
Is the free plan useful?
Fifty credits is enough to test data accuracy on a handful of your own target accounts, which is exactly what you should do: accuracy varies sharply by territory and industry, and it is the only thing that matters in this category. Check names you already know the answers for.
Can Seamless clean my CRM data as well as run outbound?
The homepage says so, as a vendor claim. Among its AI agents for sales teams it lists an Ops Agent described as one that "Cleans CRM data and launches outbound automatically", and its Data Engine names a separate CRM Enrich product (seamless.ai, read 10 November 2026). Which CRMs it connects to, and whether either sits inside a plan or is billed on top, is not confirmed. Data Enrichment and Autopilot were marked Add-on on every tier on the old pricing page (7 September 2026), so ask for both to be priced in the quote.
Is this a hands-on review of Seamless.ai?
Yes. We tested Seamless.ai ourselves on 2026-10-31; the section above says what we tested, what we found and what we did not test, and where a figure comes from the vendor's own documentation instead. Most of our reviews are researched rather than run; we say which is which. We name what each tool is good and bad at, and we earn a commission only if you sign up, at no cost to you.
- Buyer reviews on G2, Capterra, Trustpilot, Reddit and the BBB, read August 2026.
- Read 2026-09-30 on seamless.ai/pricing, seamless.ai/pricing-inquiry, Seamless's help centre and seamless.ai/llms.txt.
